Overview - -sf is an **autopilot for software engineering work** that the user owns end-to-end: the user states a goal (`/sf plan "add OAuth"`) and sf decomposes, plans, executes, verifies, reviews, and merges through a structured phase pipeline without per-unit human intervention. The user watches or steers; the agent executes. - -sf v3 is the next major version of singularity-forge, built directly on the [pi-mono](https://github.com/badlogic/pi-mono) SDK packages already vendored under `packages/pi-*`: - -| Vendored package | Role | -|---|---| -| `@singularity-forge/pi-coding-agent` | Coding agent CLI primitives (vendored from pi-mono) | -| `@singularity-forge/pi-agent-core` | General-purpose agent core | -| `@singularity-forge/pi-ai` | Unified LLM API across 20+ providers | -| `@singularity-forge/pi-tui` | TUI primitives | - -sf adds the autopilot layer on top: phase state machine, persistent agent fleet, knowledge integration with Singularity Memory, gates, hooks, worktree management, blockers and dispatch scheduling. The agent harness itself (tool execution, model calls, hook plumbing) is pi-mono's; the orchestration is sf's. - -### 1.1 Existing infrastructure - -sf already ships: - -- **`packages/daemon`** — long-lived background process that absorbs Node.js cold-start cost. The autopilot loop runs in the daemon; CLI invocations (`/sf status`, `/sf next`) talk to it via local RPC. -- **`packages/mcp-server`** — exposes sf orchestration tools (plan/dispatch/status) via MCP so other agent CLIs (Claude Code, Cursor) can call sf as a backend. -- **`packages/native`** — N-API bindings for performance-critical native (Rust) code where TypeScript would be too slow. -- **`packages/rpc-client`** — standalone RPC client SDK with zero internal dependencies, used by the CLI to talk to the daemon. - -This spec defines the v3 contract that ties these together with the gen-2 harness control pattern that GSD established (drop into pi-mono primitives directly; do NOT layer skills on top and hope the LLM follows them). - -### 1.2 Versioning - -sf follows [SemVer 2.0](https://semver.org/). For this spec: - -- **Patch** (1.x.Y): clarifications, conformance refinements, no behavioural change. -- **Minor** (1.Y.0): additions to the harness API, schema, or CLI that do not break existing implementations. -- **Major** (X.0.0): breaking changes to schema, hook contracts, or harness API. - -v1.0.0 (this spec, when finalised) freezes §§3 (Data Model), 4 (Phase State Machine), 6 (Worker Attempt Lifecycle), 10 (Hooks), 14 (Configuration), and 26 (Conformance) — changes to those sections post-v1 require a major bump. sf v3 MUST NOT rebuild what pi-mono already provides: - -- Agent loop via `pi-coding-agent` -- Multi-provider LLM (20+ providers including Anthropic, OpenAI, Gemini, Groq, Bedrock, Azure, Ollama) via `pi-ai` -- MCP client (`modelcontextprotocol/go-sdk`) -- LSP integration -- SQLite state via `ncruces/go-sqlite3` -- TUI primitives via `pi-tui` -- Tool execution (bash, file read/write, grep, web search, sourcegraph) -- Agent Skills open standard (`internal/skills/`) -- Permission service with pubsub, persistent grants, hook pre-approval -- PreToolUse hook system with allow/deny/halt, input rewriting, multi-hook aggregation - -This specification covers only what sf v3 adds on top of pi-mono. Behaviour already provided by the pi-mono SDK packages is inherited. - -**Project-level conformance.** sf MUST enforce JSDoc on every exported function, type, and class in its harness modules via a CI check (`scripts/specs-check.ts` — an AST walk, no external linter dependency). This applies to sf's own development; it is not a runtime gate against user projects. - ---- - -## 2. Definitions - -**Unit** — the atomic unit of work. Has a type (`milestone`, `slice`, `task`), a phase, and an attempt counter. Units are ephemeral — they complete or fail and are archived. - -Unit IDs use the format `{type}/{slug}` where slug is hierarchical: -- Milestone: `milestone/m{n}` (e.g. `milestone/m2`) -- Slice: `slice/m{n}/s{n}` (e.g. `slice/m2/s3`) -- Task: `task/m{n}/s{n}/t{n}` (e.g. `task/m2/s3/t1`) - -The slug encodes the parent hierarchy redundantly with `units.parent_id` to make trace and log lines self-describing without requiring a join. - -**Phase** — a named stage of a unit's lifecycle. The harness owns all phase transitions; no other layer may transition a phase directly. - -**Attempt** — one dispatch of a worker for a unit. A unit may accumulate multiple attempts across failures and retries. - -**Turn** — one model call within an attempt. An attempt consists of one or more turns. The first turn receives the full task prompt; subsequent turns receive continuation guidance only. - -**Project** — a directory with `.sf/config.toml`. The project root is the directory containing `.sf/`. Each project has its own SQLite DB at `/.sf/sf.db` — `~/.sf/sf.db` is the cross-project default DB used only when no project-local DB exists. Multiple projects on the same machine MUST use separate `.sf/` directories and therefore separate DBs, locks, and trace files. - -**Session** — a top-level container scoped to one project, with a stable ULID, persisting across process restarts of the same project. A session is created on the first `/sf auto` or `/sf next` invocation in a project and reused on subsequent invocations until explicitly ended (`/sf session end`) or until 30 days of inactivity. The session holds the running state for all units, the context budget, and the supervisor state. - -**Harness** — the layer between pi-coding-agent's agent loop and sf's orchestration logic (milestones, phases, git, worktrees). It owns: context budget, phase transitions, unit lifecycle hooks, session contract, observability, and supervision. Nothing in the planning or git layers MUST reach past the harness boundary into pi-coding-agent directly. - -**Worker** — the process (local or SSH-remote) that executes one attempt. Spawned by the orchestrator. - -**Orchestrator** — central process. Owns the scheduling loop, in-memory state, and all SQLite writes. Always runs locally even in distributed deployments. - -**Singularity Memory** (`sm`) — the durable knowledge layer. An HTTP + MCP server holding memories, learnings, and anti-patterns across sessions, projects, and tools. Originally derived from `vectorize-io/hindsight` (MIT) and assimilated into our codebase under `singularity_memory_server/`; we own the engine. Runs either embedded (in-process for single-user sf) or remote (shared service on tailnet, reachable from sf, Hermes, OpenClaw, Claude Code, Cursor, etc.). Not SQLite — knowledge lives in Singularity Memory; SQLite holds only orchestration state. - -**Skill** — a `SKILL.md` file providing prompt guidance to the agent. Inspirational, not enforced. - -**Workflow template** — a TOML file specifying the exact phase sequence the harness enforces for a class of work. Programmatic, not a suggestion to the agent. - -**Plan** — the local source of truth for work units. Created by the user via `/sf plan "..."` or by editing `.sf/plan.md`. Decomposed by sf into milestones → slices → tasks. There is no external tracker — sf's SQLite DB is authoritative. (External visibility, e.g. mirroring to GitHub Issues for teammates, is achieved via PostUnit hook scripts, not a built-in tracker integration. See § 10.) - -**Claim** — a soft lock recorded on a `units` row indicating the orchestrator is currently dispatching it. Stored as `claim_holder` (worker host or PID) and `claim_until` (UNIX ms expiry). A claim is released on terminal phase, worker exit, or claim expiry. Prevents two workers picking up the same unit simultaneously. The orchestrator MUST sweep expired claims at the start of every poll tick: any row with `claim_until < now()` and `phase_status = 'running'` is reset to `phase_status = 'interrupted'` and `claim_holder = NULL`. - -**Run** — the unifying abstraction for one execution of the worker attempt lifecycle (§ 6). A run is either a **unit attempt** (driven by the phase state machine) or a **persistent agent run** (driven by inbox messages). The `runs` table (§ 3.5) records both, distinguished by `run_kind`. Trace, billing, and supervisor monitoring all key on `run_id`. - ---- - -## 3. Data Model - -> **Status: PARTIAL** — sf has `milestones`/`slices`/`tasks` as 3 separate tables instead of one `units` table with `type` discriminator. Plus richer planning tables (`decisions`, `requirements`, `artifacts`, `assessments`, `replan_history`). Reconciliation: either migrate to single `units` table or keep 3-table shape and update spec. - - -The orchestrator uses a single SQLite database **per project** at `/.sf/sf.db` (or `~/.sf/sf.db` for non-project sessions) for **orchestration state only**: sessions, units, phase transitions, blockers, gate results, benchmarks, circuit breakers, and persistent agents. **Knowledge** (memories, learnings, anti-patterns, codebase context) lives in Singularity Memory (§ 16), not SQLite. - -All primary keys for runtime-allocated rows (sessions, units, runs, agents, agent_messages, agent_inbox, gate_results, session_blockers, pending_retain) MUST be [ULIDs](https://github.com/ulid/spec) — sortable by creation time without a separate timestamp column.

Rows MUST NOT be deleted or modified after insert. `delivered` is the only mutable field. - -### 3.3 No external tracker - -> **Status: EXISTS** — sf already operates from local SQLite only; no Linear/Jira/etc. integration in core. - - -sf v3 does **not** integrate with external task trackers (Linear, GitHub Issues, Jira). Work units are entirely local — created by `/sf plan "..."`, edited via `.sf/plan.md`, and stored in `units` (§ 3.1). The local SQLite DB is the only authoritative source of unit state. - -This is a deliberate simplification from the earlier draft. Reasons: - -- sf's gen-2 model is "user states a goal, sf decomposes and executes" — not "team files tickets in Linear, sf picks them up." The autopilot doesn't need an external queue. -- External tracker integration adds network dependency on the orchestrator's critical path (rate limits, outages, GraphQL pagination edge cases). -- Symphony-style reconciliation (cancel mid-run when external state changes) doesn't apply when the only source is internal. - -**External visibility is achieved via hooks, not core integration.** A PostUnit hook can call `gh issue comment`, `slack-cli send`, or any other publishing target to broadcast progress. Read-side stays in sf's DB; write-side goes through hooks. See § 10.5.1 for an example GH Issues publishing hook. - -**Sources of truth for unit creation:** - -| Source | When | -|---|---| -| `/sf plan ""` CLI command | Adds a milestone with sf-decomposed slices and tasks | -| `.sf/plan.md` file edit | Declarative; sf re-reads and reconciles on `/sf plan reload` | -| `/sf dispatch ` | One-off task, no enclosing milestone | -| `/sf agent run ""` | Wakes a persistent agent; not a unit (§ 17.1) | - -There is no poll loop against any external API. The orchestrator's poll cycle (§ 5.1) reads only from local SQLite. - ---- - -## 4. Phase State Machine - -> **Status: PARTIAL** — phases `research`/`plan`/`execute`/`review`/`complete` exist in sf prompts. Spec's `tdd`, `verify`, `merge`, `reassess`, `uat` need verification — may exist under different names (`assessments`, `replan_history` table hints at reassess). - - -### 4.1 Phase enum - -```go -type Phase int - -const ( - PhaseResearch Phase = iota // map the problem, gather context - PhasePlan // decompose into slices and tasks, get sign-off - PhaseExecute // write the code - PhaseTDD // write tests for what was just built; red → green - PhaseVerify // run full test suite + lint + type check; gates pass - PhaseReview // structured self-review: correctness, style, security - PhaseMerge // commit, push, open PR - PhaseComplete // unit done; result recorded; artifact archived - PhaseReassess // re-enter planning with failure context - PhaseUAT // human acceptance; only when workflow has require_uat = true -) -``` - -### 4.2 Standard flow - -`Research → Plan → Execute → TDD → Verify → Review → Merge → Complete` - -Permitted non-standard transitions: - -| Trigger | Transition | -|---|---| -| Gate failure in Verify (attempt < max_retries) | `Verify → Execute` | -| Gate failure in Verify (attempt = max_retries) | `Verify → Reassess` | -| Review finds a real problem | `Review → Execute` | -| Merge conflict | `Merge → Reassess` | -| External cancellation | Any → (AttemptCanceled, no phase write) | - -All other transitions are REJECTED at the harness boundary with a typed error. The harness MUST NOT silently allow invalid transitions. - -### 4.3 Attempt state - -Within each phase, individual dispatch attempts move through finer-grained states: - -```go -type AttemptState int - -const ( - AttemptPreparingWorkspace AttemptState = iota - AttemptBuildingPrompt - AttemptLaunchingAgent - AttemptInitializingSession - AttemptStreamingTurn - AttemptFinishing - AttemptSucceeded - AttemptFailed - AttemptTimedOut - AttemptStalled // stall_timeout exceeded since last agent event - AttemptCanceled // issue became non-active mid-run (reconciliation) -) -``` - -`AttemptCanceled` is distinct from `AttemptFailed`. It means the work was valid but the task was externally invalidated (deleted, moved to a terminal state, superseded). The harness MUST NOT retry a canceled attempt — it releases the slot and moves on. - -### 4.4 Turn kind - -```go -type TurnKind int - -const ( - TurnFirst TurnKind = iota // full rendered task prompt - TurnContinuation // short continuation guidance, same thread -) -``` - -Turn 1 of every attempt is always `TurnFirst`. Turns 2+ are `TurnContinuation`. The harness determines `TurnKind`; the agent never does. - -### 4.5 Workflow templates - -A workflow template MUST be a TOML file in `.sf/workflows/.toml`. The harness reads the template, constructs the phase sequence from it, and enforces it programmatically. The agent has no say in phase ordering or skipping. - -```toml -# .sf/workflows/feature.toml -name = "feature" -phases = ["research", "plan", "execute", "tdd", "verify", "review", "merge", "complete"] -require_tdd = true # PhaseTDD is enforced; skipping is a gate violation -require_review = true -require_uat = false # if true, PhaseUAT is inserted before PhaseComplete -max_retries = 3 # per gate in PhaseVerify -max_reassess = 2 - -# .sf/workflows/release.toml — uses UAT -name = "release" -phases = ["research", "plan", "execute", "tdd", "verify", "review", "uat", "merge", "complete"] -require_tdd = true -require_review = true -require_uat = true # halts after UAT enters; only resumes on /sf uat-approve -max_retries = 3 - -# .sf/workflows/spike.toml -name = "spike" -phases = ["research", "plan", "execute", "complete"] -require_tdd = false -require_review = false -max_retries = 0 -``` - -PhaseUAT halts the auto-loop with `SignalPause` and waits for `/sf uat-approve ` (advance to PhaseMerge) or `/sf uat-reject "reason"` (advance to PhaseReassess). The harness MUST fail startup if a configured workflow template references an unknown phase or includes `uat` without `require_uat = true`. - -#### Workflow selection at dispatch - -The workflow used for a given unit is determined in this order: - -1. Explicit unit metadata: `metadata.workflow = ""` set at `/sf plan` time. -2. Project default: `[harness] default_workflow = "feature"` in `.sf/config.toml`. -3. Built-in fallback: `feature` (if available) else the first workflow in `.sf/workflows/`. - -The selected workflow is recorded in `units.workflow` at dispatch time and never re-evaluated for that unit, even on retry — workflow stability across attempts is a hard guarantee. Additionally, the *content* of the chosen template is hashed (SHA-256) and stored in `units.workflow_hash`. If the on-disk template changes mid-session, the harness uses the pinned hash's content (cached in SQLite at `workflow_pins.content`) for that unit; new units pick up the new content. This prevents in-flight units from silently changing rules. - -```sql -CREATE TABLE workflow_pins ( - hash TEXT PRIMARY KEY, -- SHA-256 of template content - name TEXT NOT NULL, - content TEXT NOT NULL, -- frozen TOML at first pin - pinned_at INTEGER NOT NULL -); -``` - -### 4.6 PhaseReassess - -`PhaseReassess` is entered when a unit cannot make progress through normal phases (gate failed `max_retries` times, merge conflict, supervisor halt). The Reassess agent is dispatched at the **`reasoning`** tier with `Think: true` and is given: - -- The original task description. -- The full failure trail: gate output, last `max_retries` attempt errors, last commit history. -- The unit's plan (from `.sf/active/{unit-id}/plan.md`). - -The Reassess agent MUST output one of: - -| Outcome | Effect | -|---|---| -| **Re-plan** | Writes a new `plan.md`, transitions back to `PhasePlan`. Counter `max_reassess` decrements. | -| **Abandon** | Writes a `decision.md` explaining why the task cannot succeed; transitions to `PhaseComplete` with verdict `abandoned`. Any registered visibility hook (e.g. GH Issues comment) fires from the standard PostUnit pipeline. | -| **Escalate** | Halts auto-loop with `SignalPause`; writes a `human-question.md` with concrete questions for the operator. Resumes on `/sf reassess-resolve `. | - -If `max_reassess` hits zero on a Re-plan path, the next entry into PhaseReassess MUST be Abandon or Escalate; Re-plan is rejected. - -### 4.7 Phase transition rules - -1. All phase transitions MUST go through a single `Harness.Transition(ctx, from, to, reason)` method. -2. `Transition` MUST persist the `PhaseTransition` record to SQLite BEFORE the new phase begins. A crash mid-phase means on resume the harness re-enters the last committed phase cleanly (see § 4.8). -3. `Transition` MUST emit a pubsub `PhaseChange` event after the SQLite write. The TUI subscribes — it MUST NOT poll phase state directly. -4. The harness MUST set `Think: true` on the model config for `Research`, `Plan`, and `Reassess` phases. The agent does not control this. -5. **`PhaseChange` is non-vetoable.** Hook subscribers receive a notification *after* the transition is committed; they cannot block or reject. Hooks that need veto semantics MUST register on `PreDispatch` instead, which fires before the next dispatch and IS vetoable. - -### 4.8 Crash recovery - -In-memory scheduler state is intentionally not persisted (§ 20.2). On restart, the orchestrator MUST follow this exact sequence: - -1. **Acquire project lock** at `/.sf/run.lock` (PID file). Stale lock (PID not in `/proc` on Linux, `kill(pid, 0)` on other Unixes) is cleaned and logged. The lock is per-project; multiple projects can run auto concurrently on the same machine. -2. **Mark interrupted units.** All units with `phase_status = 'running'` are updated to `phase_status = 'interrupted'`. This is the only schema-level recovery action. -3. **Run startup cleanup** (§ 5.6) — move stale active artifacts to archive. -4. **Resume from the last committed phase boundary.** Each `interrupted` unit is treated as eligible for fresh dispatch; the worker re-enters at `unit.phase` with a new attempt number (`unit.attempt + 1`). The agent receives a `last_error` of `"resumed_after_crash"` so the prompt can warn the agent. -5. **Begin polling.** Resume normal poll cycle. Operator-issued `/sf abandon` commands made during the outage are visible via the next poll because they're persisted in `units.phase_status`. - -The harness MUST NOT replay tool calls. It MUST NOT attempt to "resume" a partial agent session. The crash recovery model is **fresh dispatch from the last persisted phase boundary**, not transparent continuation. - -**Side effects are not rolled back.** A crash mid-Merge may have produced a partial commit, push, or PR. The agent on retry sees the existing commits and either continues from there or surfaces a conflict. This MUST be documented in the Merge phase prompt: "if you see existing commits from a previous attempt, integrate them; do not start over." - -**Workspace state is preserved.** A crashed worker's workspace remains on disk; the next attempt reuses it (`ensure_workspace` returns `created=false`). The `before_run` hook is responsible for any cleanup (e.g. `git stash`, `npm clean`) appropriate for the project. - ---- - -## 5. Orchestration Loop - -> **Status: EXISTS** — `src/resources/extensions/sf/auto-loop.ts`, `auto-dispatch.ts`, `auto-supervisor.ts`. - - -### 5.1 Poll cycle - -The orchestrator runs a single goroutine that polls on a configurable interval (default 1s). Each tick: - -1. Re-check config stamp (§ 14.3). -2. Fetch eligible units from SQLite. -3. Apply priority sort (§ 5.2). -4. For each eligible unit (up to capacity), dispatch a worker. -5. Check running workers for stalled/timed-out attempts. -6. Write orchestrator snapshot to HTTP API state (§ 19.4). - -The orchestrator MUST be the single authority for all in-memory scheduler state. No other goroutine writes scheduler state. - -### 5.2 Priority ordering - -When multiple units are eligible, the orchestrator sorts them: - -1. **Explicit priority** — `priority` 1 (urgent) before 4 (low); `NULL` sorts last. -2. **Blocker-free first** — units with no non-terminal upstream blockers before blocked units. -3. **Phase order** — earlier phases first (Research before Execute) within the same priority bucket. -4. **Created-at** — oldest first as tie-breaker. -5. **Unit ID lexicographic** — final deterministic tie-breaker. - -This ordering is re-evaluated fresh on every poll tick. - -### 5.3 Blocker-aware dispatch - -A unit MUST NOT be dispatched if any of its upstream dependencies (in `task_blockers`) are in a non-terminal state. - -**Terminal** means `PhaseComplete`, `PhaseReassess` (resolved), or explicitly cancelled. **Non-terminal** means any other state, including `PhaseVerify` in progress. - -A dependency that failed and was marked abandoned is terminal and MUST NOT block downstream dispatch. - -Blocked units stay queued and are re-evaluated on the next poll tick. No backoff, no retry counter increment for a blocked wait. - -### 5.3.1 Atomic claim acquisition - -The orchestrator acquires a claim with a single conditional UPDATE: - -```sql -UPDATE units - SET claim_holder = ?, claim_until = ?, phase_status = 'running', updated_at = ? - WHERE id = ? - AND (claim_holder IS NULL OR claim_until < ?); -- ? = now() -``` - -Dispatch proceeds only if `rows_affected = 1`. This makes the claim race-free at the DB level and supports multiple orchestrators against the same `~/.sf/sf.db` even though SF normally runs as a singleton (one process per `~/.sf/run.lock`). The atomic claim is the safety net if the lock fails (e.g. shared NFS, broken filesystem semantics). - -`units.attempt` is the **current** attempt counter (used as the `attempt` prompt template variable). Historical attempts live in `runs` (§ 3.1). Authority: `units.attempt` is incremented exactly when a new `runs` row is inserted; the two are kept in sync inside the same transaction. - -### 5.4 Per-phase concurrency - -The harness MUST NOT exceed `max_agents_by_phase[phase]` concurrent units in any given phase. When a phase slot is full, further dispatches for that phase wait until the next tick. - -```toml -[harness.concurrency] -max_agents = 10 -max_agents_by_phase.execute = 4 -max_agents_by_phase.tdd = 4 -max_agents_by_phase.verify = 10 -``` - -### 5.5 Continuation retry and exponential backoff - -**After a normal (clean) exit** from a worker, the orchestrator MUST schedule a 1-second continuation retry to re-poll eligibility. If the unit is still active, a new session starts. If terminal, the claim is released. This is not a failure retry. - -### 5.4.1 Turn outcome signal - -Between transport-level "turn ran cleanly" and phase-level "gate passed," the harness MUST capture a per-turn semantic signal. After every turn, the harness inspects the model output for an explicit terminal marker: - -| Marker (in agent output) | Meaning | Effect | -|---|---|---| -| `complete` | Agent considers this turn's goal achieved | Recorded; allow continuation if max_turns_per_attempt not reached | -| `blocked` | Agent stuck, need user input or escalation | Triggers `SignalPause` if auto-mode | -| `giving_up` | Agent has decided the task can't be done | Ends attempt; transitions to PhaseReassess | -| (no marker) | Default success | Continue normally | - -The marker is parsed from the last 200 chars of the agent's response. Markers appearing earlier are ignored (prevents partial-quote false positives). This gives the harness a checkpoint *between* turns without waiting for a phase boundary. - -The agent prompt template (`prompts/execute-task.md`) instructs the agent to emit one of these markers at end-of-turn. Compliance is best-effort — absence of a marker is treated as default success. - -**After an abnormal exit**, exponential backoff. `attempt` is 1-indexed (first try = 1, first retry = 2, …): - -``` -delay = min(10s × 2^(attempt - 1), max_retry_backoff) -``` - -| Attempt | Delay before next dispatch | -|---|---| -| 1 (first try) | (no retry yet) | -| 2 (first retry) | 20 s | -| 3 | 40 s | -| 4 | 80 s | -| 5 | 160 s | -| 6+ | capped at `max_retry_backoff` (default 5 min) | - -Configurable: `[harness] max_retry_backoff = "5m"`, `[harness] max_attempts = 6`. - -### 5.6 Startup cleanup - -On startup, the orchestrator MUST: - -1. Scan `.sf/active/` for unit artifacts whose tasks are in terminal states. -2. Move stale active artifacts to `.sf/archive/` atomically (rename, not copy+delete). -3. Mark any running/claimed units as interrupted in SQLite. -4. Release all worker slots. - ---- - -## 6. Worker Attempt Lifecycle - -> **Status: EXISTS** — `src/resources/extensions/sf/auto.ts` and surrounding modules. - - -The exact sequence inside a single worker attempt: - -``` -run_worker_attempt(unit, attempt): - # 1.

Teardown - agent.stop_session(session) - run_hook_best_effort("after_run", workspace, unit) - exit_normal() -``` - -Rules: -- `before_run` hook failure is fatal — the harness MUST fail the attempt without starting the session. -- `after_run` hook is always attempted, even after failure. Its failure is logged but MUST NOT change the attempt outcome. -- The unit state re-check between turns MUST happen before building the next turn prompt. A canceled unit MUST NOT receive another turn. - ---- - -## 7. Prompt Contract - -> **Status: PARTIAL** — `auto-prompts.ts` and `commands-handlers.ts` load templates; strict-variable-mode behavior needs verification. - - -### 7.1 Template variables - -Every prompt template MUST be rendered with a strict variable checker. An unknown variable in the template MUST cause `loadPrompt` to panic at startup rather than silently render an empty string. - -Canonical variables for execute-task templates: - -| Variable | Type | Notes | -|---|---|---| -| `unit_id` | string | Stable unit identifier | -| `unit_type` | string | `"milestone"` \| `"slice"` \| `"task"` | -| `phase` | string | Current phase name (`"execute"`, `"tdd"`, etc.) | -| `attempt` | int \| null | `null` on first dispatch; integer ≥ 1 on retry | -| `session_id` | string | Stable session UUID | -| `issue` | object | Full issue/task struct as flat map | -| `last_error` | string \| null | Injected automatically when `attempt >= 1` | - -When adding a new `{{variable}}` to any template: (1) pass it in every `loadPrompt` call site, (2) add a placeholder in every test that renders that template, (3) recompile. Skipping either step causes a startup panic. - -### 7.2 Continuation turns - -A `TurnContinuation` MUST receive a short guidance prompt, not the full task prompt. The full prompt is already in the thread history — resending it inflates context and degrades model reasoning. The continuation prompt MUST NOT re-state the task description; it provides only steering context for the current turn. - -### 7.3 Attempt variable semantics - -The `attempt` variable enables prompt templates to give different instructions to retrying agents vs. fresh starts. A retry prompt SHOULD include: `"your previous attempt failed with: {{last_error}} — focus on that specifically."` The harness injects `last_error` automatically on `attempt >= 2`. - -**`last_error` is only injected on `TurnFirst` of attempts ≥ 2.** Continuation turns within the same attempt have already established context and don't need it. A turn failure within an attempt always fails the entire attempt (§ 6); there are no mid-attempt error injections to reason about. - -`last_error` content MUST be capped at 4 KB. Larger payloads (gate output, lint dumps, traceback) are truncated head-and-tail: 2 KB from the start, marker `... [truncated, full payload at ] ...`, then 2 KB from the end. The full payload is written to `.sf/active/{unit-id}/last-error-full.txt` so the agent can `read_file` it if the truncated context isn't enough. - -### 7.4 `turn_input_required` in auto-mode - -When the agent raises `turn_input_required` during auto-mode, the harness MUST respond according to the `turn_input_required` config (default: `"soft"`): - -- **`"soft"`** — inject `"This is a non-interactive session. Operator input is unavailable."` as a `user` role turn and let the session continue. The agent adapts. -- **`"hard"`** — end the attempt immediately, record `ErrTurnInputRequired`, schedule failure retry. - -In interactive/step mode, the harness MUST surface the request to the user via the TUI and MUST NOT auto-respond. It waits up to `unit_timeout` before failing. - -The harness MUST NOT leave a run stalled indefinitely waiting for interactive input in any mode. - ---- - -## 8. Context Budget - -> **Status: EXISTS** — `src/resources/extensions/sf/auto-budget.ts` with threshold logic; `auto-recovery.ts` for compaction. - - -### 8.1 Budget type - -```go -type Budget struct { - MaxTokens int - UsedTokens int - CompactAt float64 // fraction e.g. 0.80 - HardLimitAt float64 // fraction e.g. 0.95 -} - -func (b *Budget) ShouldCompact() bool { - return float64(b.UsedTokens)/float64(b.MaxTokens) >= b.CompactAt -} - -func (b *Budget) AtHardLimit() bool { - return float64(b.UsedTokens)/float64(b.MaxTokens) >= b.HardLimitAt -} -``` - -### 8.2 Rules - -- The harness MUST update `UsedTokens` after every model response. The agent loop MUST NOT manage budget. -- When `ShouldCompact()` is true, the harness MUST trigger compaction before the next turn, not mid-turn. -- When `AtHardLimit()`, the harness MUST halt the current unit, snapshot state, and surface `ErrBudgetExhausted`. It MUST NOT let the agent proceed and hit a provider context error. -- Budget state MUST be persisted to SQLite after every turn so crash recovery can restore it. - -### 8.3 Compaction - -When compaction fires (budget at compact threshold): - -1. Write a `session_summary` entry to Singularity Memory via `retain`. -2. Clear the hot cache (in-memory last-N turns). -3. Start the next turn with a fresh context window seeded by a `recall` from Singularity Memory. - -Compaction MUST NOT truncate the window — it MUST replace it with a fresh recall. A truncated window loses structure; a recalled window gains relevance. - -**Agent run compaction preserves the wake context.** For persistent agent runs, the compacted window MUST include verbatim: -- The wake message that started this run. -- The most recent 3 inbox arrivals delivered in this run. -- The agent's full `agent_memory_blocks` (these are durable anyway, but they go above the recall block). - -Compaction without this preservation can drop the originating intent and cause the agent to lose thread continuity mid-run. - -### 8.4 Token accounting precision - -Provider responses arrive as either absolute thread totals or per-turn deltas. The harness MUST prefer absolute totals (`thread/tokenUsage/updated`-style events) and MUST track the last-reported total to compute deltas, preventing double-counting. - -Aggregate totals (input, output, cache-read, cache-write, cost-usd) MUST accumulate in orchestrator state and be included in every runtime snapshot. - ---- - -## 9. Supervision - -> **Status: EXISTS** — `abandon-detect.ts`, `auto-budget.ts`, `auto-recovery.ts`, `auto-timeout-recovery.ts`, `blocked-models.ts` cover most checks. Circuit breaker and ModelUnavailable specifics need verification. - - -### 9.1 Supervisor interface - -The harness MUST run a supervisor goroutine alongside the agent loop. The supervisor communicates exclusively via pubsub — it MUST NOT touch agent state directly. - -```go -type SupervisorCheck interface { - Name() string - Check(ctx context.Context, state SupervisorState) SupervisorSignal -} - -type SupervisorSignal int - -const ( - SignalOK SupervisorSignal = iota - SignalWarn // log, surface in TUI - SignalPause // pause auto-loop, wait for user - SignalAbort // stop unit, mark interrupted -) -``` - -### 9.2 Built-in checks - -| Check | Trigger | Signal | -|---|---|---| -| `StuckLoop` | Same phase for > N turns with no successful tool calls | `SignalPause` | -| `BudgetWarning` | Context approaching compaction threshold | `SignalWarn` | -| `TimeoutCheck` | Unit running longer than `unit_timeout` | `SignalAbort` | -| `AbandonDetect` | Agent producing output with no tool calls | `SignalPause` | -| `GitDivergence` | Working branch diverged from base unexpectedly | `SignalPause` | -| `BlockerCheck` | Upstream dependency moved to non-terminal state mid-run | `SignalPause` | -| `ModelUnavailable` | Provider returns "model not supported / not found" class error | `SignalAbort` immediately (not after timeout) | -| `CircuitBreaker` | Same model fails 3 consecutive times within a session | Trip circuit; `SignalAbort` on next dispatch to tripped model | - -### 9.3 Circuit breaker - -When the circuit trips for a model: - -- Write circuit state to SQLite (`circuit_breakers` table — `model`, `tripped_at`, `resets_at`). -- Subsequent dispatches in that tier MUST skip the tripped model. -- Circuit auto-resets after 24 hours or on explicit `/sf reset-circuits`. -- The circuit state MUST survive a process restart. - -### 9.4 Supervisor constraints - -- The supervisor MUST NOT call `os.Exit` or panic. -- The supervisor MUST NOT write to agent state or SQLite unit state directly. -- The auto-loop acts on `SignalPause` and `SignalAbort`. The TUI shows warnings on `SignalWarn`. - -### 9.5 SignalAbort and in-flight tool calls - -When the harness receives `SignalAbort` while a tool call is in flight (e.g. a long-running `bash` subprocess), it MUST follow this sequence: - -1. Cancel the tool call's context (Go `context.CancelFunc`). Cooperative cancellation MUST be honoured by built-in tools. -2. Wait up to `[harness] tool_abort_grace = "5s"` for the tool to exit cleanly. -3. After the grace period, send `SIGTERM` to any tool subprocess. -4. Wait an additional `[harness] tool_abort_kill = "3s"`. -5. If the subprocess is still running, send `SIGKILL`. - -Total worst case: 8 seconds from `SignalAbort` to forcible termination. The harness MUST NOT hang the orchestrator waiting on a non-cooperating tool call. - -After the tool call ends (cleanly or via SIGKILL), the harness records the run as `outcome = canceled` with `error_code = canceled_by_supervisor` and emits the `after_run` hook before releasing the slot. - ---- - -## 10. Hook Pipeline - -> **Status: EXISTS** — `src/resources/extensions/sf/post-unit-hooks.ts`, `bootstrap/register-hooks.ts`. Per-hook timeouts and exact event set (PreDispatch/AutoLoop/etc.) need cross-check. - - -### 10.1 Events - -The harness extends pi-coding-agent's hook system with sf-specific events: - -```go -const ( - // Existing pi-coding-agent event - EventPreToolUse = "PreToolUse" - - // Unit lifecycle - EventPreDispatch = "PreDispatch" // before a unit is dispatched; can block - EventPostUnit = "PostUnit" // after a unit completes - EventPhaseChange = "PhaseChange" // on phase transition - - // Auto-loop - EventAutoLoop = "AutoLoop" // each iteration of the auto-loop - - // Worktree - EventWorktreeCreate = "WorktreeCreate" - EventWorktreeDelete = "WorktreeDelete" - EventMergeReady = "MergeReady" - EventMergeConflict = "MergeConflict" - - // Agent fleet - EventAgentWake = "AgentWake" // target agent should start/resume - EventAgentMessage = "AgentMessage" // message routed (TUI + tracing) - EventAgentIdle = "AgentIdle" // agent completed its turn, inbox empty -) -``` - -### 10.2 UnitResult payload - -PostUnit hooks receive: - -```go -type UnitResult struct { - UnitID string - UnitType string // "milestone" | "slice" | "task" - Phase Phase - Verdict string // "success" | "failure" | "abandoned" - Duration time.Duration - InputTokens int - OutputTokens int - CacheHits int - CostUSD float64 - Model string - WorkerHost string - Error error - Learnings []string -} -``` - -The payload is serialized to JSON and passed to hook subprocesses via stdin. - -### 10.3 Hook execution rules - -- PostUnit hooks run **sequentially**, not concurrently. The next dispatch MUST NOT begin until all PostUnit hooks have returned. -- A hook subprocess that exits non-zero for `PreDispatch` or `PostUnit` MUST trigger `SignalAbort`. The harness stops the session and marks it `SessionFailed`. -- Hook timeouts are per-hook-type. Defaults: - - | Hook | Default | Rationale | - |---|---|---| - | `before_run` | `120s` | Cleanup, dependency install can take time | - | `after_run` | `30s` | Best-effort teardown | - | `after_create` | `120s` | First-time setup | - | `before_remove` | `30s` | Cleanup | - | `pre_dispatch` | `15s` | Should be a fast check | - | `post_unit` | `60s` | Subprocess work; longer for git push | - | `doc_sync` (built-in) | `5m` | Runs an agent dispatch over the diff | - - All overridable in config via `[harness.hooks.timeouts.] = ""`. A timeout kills the hook and logs. A `PostUnit` hook timeout MUST NOT block the next dispatch. -- The git service subscribes to PostUnit via a hook and handles commits, branch creation, and push. The harness MUST NOT call `git` directly. -- Singularity Memory feedback (retain learnings, mark anti-patterns) is emitted from a built-in PostUnit hook (not a subprocess) — it calls the Singularity Memory client directly. -- PostUnit hook results MUST be written to the trace as child spans of the unit span. - -### 10.4 Tool response contract - -Every tool call — successful or not — MUST return a response in this shape: - -```go -type ToolResponse struct { - Success bool `json:"success"` - Output string `json:"output"` - ContentItems []ContentItem `json:"contentItems"` -} - -type ContentItem struct { - Type string `json:"type"` // always "inputText" for text results - Text string `json:"text"` -} -``` - -For successful calls: `success = true`, `output` = result summary. For unsupported or failed calls: `success = false`, `output` = human-readable error, `contentItems` lists which tools are available in the current context. The shape MUST be consistent — the agent relies on `success` to distinguish real failures from tool-not-found errors. - -If the agent calls a tool that is not registered, the harness MUST return a structured failure response and continue the session. It MUST NOT stall, panic, or exit on an unknown tool name. - -### 10.5.0 SF tool registration - -pi-coding-agent (vendored from pi-mono under `packages/pi-coding-agent/`) provides the agent's tool registry. sf adds new tools (`send_message`, `core_memory_append/replace`, `handoff`, `wait_for_reply`, `chapter_open`, `stop`, `plan_unit`, etc.) by registering them at sf-startup via pi-coding-agent's API. There is NO parallel tool registry — sf tools live in `src/resources/extensions/sf/tools/` and call into pi-coding-agent's registration during module init. - -sf-specific tools MUST: -1. Conform to the response shape of § 10.4 (`{success, output, contentItems}`). -2. Honour pi-coding-agent's `PreToolUse` hook system — they receive the same hook pipeline as built-in tools. -3. Document the auto_approve key they expect (e.g. `agent:send_message`) so projects can list them in `[harness.auto_approve.tools]`. - -This means PreToolUse hooks can deny sf tool calls just like any other; the auto-approve list scopes them; permissions are uniform. - -### 10.5.1 External visibility via PostUnit hooks (recipe) - -> **Status: NEW** — documentation-only; no `gh issue comment` recipe shipped. - - -If the user wants teammates to see sf's progress in GitHub Issues (or Slack, or any other system), this is done as a PostUnit hook script — **not** a built-in tracker integration. - -Example: `.sf/hooks/post-unit-gh.sh` - -```bash -#!/usr/bin/env bash -# Reads UnitResult JSON from stdin; posts a comment to a GitHub issue -# whose number is stored in the unit's `external_ref` field (set at plan -# time via /sf plan --link-issue=42 "..."). - -set -euo pipefail -payload="$(cat)" -issue=$(jq -r '.unit.metadata.gh_issue // empty' <<< "$payload") -verdict=$(jq -r '.verdict' <<< "$payload") -phase=$(jq -r '.phase' <<< "$payload") -[ -z "$issue" ] && exit 0 # not linked, no-op - -gh issue comment "$issue" --body "sf $phase: $verdict" -``` - -Wired in `.sf/config.toml`: - -```toml -[harness.hooks] -post_unit = ["./.sf/hooks/post-unit-gh.sh"] -``` - -The unit's `metadata.gh_issue` field is set at plan time: - -```bash -sf plan --link-issue=42 "implement OAuth" -``` - -This pattern keeps the orchestrator's critical path local (sf's DB) while still giving external visibility where the user wants it. The same pattern works for Slack, Discord, Jira, Linear, in-house dashboards — sf doesn't need to know about any of them. - -### 10.5 Doc sync (sub-step of PhaseMerge or PhaseComplete) - -> **Status: NEW** — no doc-sync sub-step found. - - -Doc sync runs as the final sub-step of the **last code-mutating phase** before `PhaseComplete`: - -- For workflows that include `PhaseMerge`: doc sync runs at end of `PhaseMerge`. -- For workflows that omit `PhaseMerge` but include `PhaseExecute` (e.g. `spike`): doc sync runs at end of the last code-mutating phase that ran. If the spike adopted a new dependency, doc sync still gets a chance to update `STACK.md`. - -It is not a separate phase and not a post-merge hook; it is the final sub-step of whichever phase was last to mutate code. - -The doc-sync sub-step: - -1. Dispatches a `fast`-tier turn against the merged diff with a short prompt asking whether project-level docs (`ARCHITECTURE.md`, `CONVENTIONS.md`, `STACK.md`) need updating. -2. The agent emits a diff (possibly empty) to stdout. -3. If the diff is non-empty, the harness surfaces it to the TUI for user approval. On approval, it is committed as `docs: sync after {unit_id}` on the same branch and the merge hook is re-triggered. -4. On empty diff, the sub-step is a no-op and PhaseMerge proceeds to PhaseComplete. - -Configuration: -- `[harness] doc_sync = false` disables the sub-step entirely. -- `[harness] doc_sync_auto_approve = true` skips the user prompt and commits the diff directly. Off by default. - ---- - -## 11. Workspace Management - -> **Status: EXISTS** — `auto-worktree.ts` plus `worktree-manager.ts`. Symlink-aware path containment specifics need verification. - - -### 11.1 Naming - -Workspace directories are derived from the unit identifier. The identifier MUST be sanitized: replace any character not in `[a-zA-Z0-9._-]` with `_`. This prevents path injection via issue identifiers containing slashes, `..`, or null bytes. - -### 11.2 Symlink-aware path containment - -Workspace path validation MUST use segment-by-segment canonicalization, not `filepath.EvalSymlinks` or `path.Clean` alone. A naive call can be defeated by a symlink that resolves outside the workspace root. - -Algorithm: - -``` -resolveCanonical(path): - segments = split(path) - resolved = root - for segment in segments: - candidate = join(resolved, segment) - stat = lstat(candidate) - if stat == symlink: - target = readlink(candidate) - # expand target relative to current resolved prefix - # restart segment walk from resolved target - elif stat == exists: - resolved = candidate - elif stat == ENOENT: - resolved = join(resolved, remaining segments) # path not yet created; OK - break - else: - return error - return resolved -``` - -After canonicalization, MUST assert `canonical_workspace` has `canonical_root + "/"` as a prefix. If it does not, reject with `ErrWorkspaceSymlinkEscape`. - -For remote workers, the same check MUST be performed via a shell script that resolves each path segment before `mkdir`. - -### 11.3 Workspace lifecycle - -1. `after_create` — runs once when the workspace directory is first created. -2. `before_run` — runs before every attempt. Fatal if it fails. -3. `after_run` — runs after every attempt (success or failure). Best-effort. -4. `before_remove` — runs before the workspace is deleted. - -All hooks run in the workspace directory as the working directory. - -### 11.4 Local workspace creation - -``` -ensure_workspace(workspace): - if directory exists: - return (workspace, created=false) - if file exists at path: - rm -rf path - mkdir -p path - return (workspace, created=true) -``` - -### 11.5 Remote workspace creation - -For SSH workers, the orchestrator runs a shell script on the remote host that atomically creates and resolves the workspace, then echoes a tab-separated marker line: - -``` -printf '%s\t%s\t%s\n' '__SINGULARITY_WORKSPACE__' "$created" "$(pwd -P)" -``` - -The orchestrator parses this line from stdout to confirm the resolved canonical path. - ---- - -## 12.

The git service commits incrementally. -- The worktree is merged at milestone PostUnit time. - -### 12.2 Rules - -- The harness MUST emit `WorktreeCreate` and `WorktreeDelete` events. It MUST NOT call `git` directly. -- `worktree_mode` is session-immutable — changing it requires restart. - -### 12.3 Merge ordering for parallel slices - -When multiple slices in `branch-per-slice` mode complete concurrently, the harness MUST merge them in **dependency-aware** order, not completion order: - -1. A slice marked `code_depends_on: ["m1/s2"]` in unit metadata is held until that upstream slice's branch has merged. -2. With no declared code dependency, slices merge in `created_at` order. -3. The merge gate is serial: only one slice's merge runs at a time per project, even if multiple are eligible. - -This is distinct from `task_blockers` (task-completion dependency). **Code dependency** means slice B's diff cannot merge cleanly before slice A's diff. Without explicit declaration, the harness assumes no code dependency and merges in creation order — accept that this can produce avoidable conflicts that the next attempt will resolve. - ---- - -## 13. Verification Gates - -> **Status: EXISTS** — `verification-gate.ts`, `verification-evidence.ts`, `auto-verification.ts`, `gate_runs` table. PhaseReview 3-pass chunking is NEW. - - -### 13.1 Configuration - -```toml -[harness.gates] -post_slice = ["./gates/run-tests.sh", "./gates/lint.sh"] -post_milestone = ["./gates/integration-tests.sh"] -``` - -### 13.2 Execution rules - -- Gates run as subprocesses. The `UnitResult` JSON is passed via stdin. -- Exit 0 = pass. Non-zero = fail. -- Fail increments the gate-level retry counter (separate from `units.attempt`). The gate retry counter resets on the next phase transition. -- Default max gate retries: 3. Configurable per gate via `[harness.gates.max_retries.]`. -- On retry, the harness re-dispatches the same unit with gate failure output appended to context. The agent MUST see what failed and why. -- After max retries, the harness transitions to `PhaseReassess` and emits `GateBlocked` on pubsub. -- Gate results MUST be stored in `gate_results` table and written as span events on the unit span. - -### 13.2.1 Gate script protocol - -Every gate script MUST adhere to this contract. Implementations that violate any rule are rejected at startup validation. - -**Environment variables provided:** - -| Variable | Value | -|---|---| -| `SF_PROJECT_ROOT` | Absolute path to project root | -| `SF_HOME` | SF data directory (`~/.sf` or override) | -| `SF_UNIT_ID` | Active unit ID (§ 2 format) | -| `SF_RUN_ID` | Active run ULID | -| `SF_PHASE` | Phase name (e.g. `verify`) | -| `SF_ATTEMPT` | Attempt counter, 1-indexed | -| `SF_GATE_NAME` | This gate's name (script basename without extension) | -| `SF_GATE_RETRY` | Gate retry counter, 0-indexed | -| `SF_WORKSPACE` | Path of the unit's workspace | -| `SF_TRACE_FILE` | Path to current day's trace JSONL | - -**Stdin:** the `UnitResult` JSON struct (§ 10.2). UTF-8, single line, terminated with `\n`. - -**Exit code:** `0` = pass; `1` = fail (retry); `2` = block (do not retry, transition straight to PhaseReassess); `3` = skip (gate is not applicable for this unit). Other codes are treated as `1`. - -**Stdout / stderr:** captured combined, truncated at 8 KB, stored in `gate_results.output`. Multi-line is fine. No structured output is required, but if the first line is valid JSON of the form `{"summary": "...", "issues": [...]}` the harness uses it for richer reporting. - -**Timeout:** default 5 minutes per gate, configurable via `[harness.gates.timeouts.]`. Timeout = SIGTERM, then 10s grace, then SIGKILL; recorded as `error_code = "gate_timeout"`. - -**Cwd:** the workspace directory. Scripts MAY assume `git status` etc. work as expected. - -```go -type GateResult struct { - GateName string - UnitID string - Passed bool - Attempt int - MaxRetries int - Output string // combined stdout+stderr, truncated at 8KB - Duration time.Duration -} -``` - -### 13.3 PhaseReview — chunked review - -Large diffs MUST NOT be reviewed in a single pass. The harness MUST split the changed file list into chunks of ≤ 300 lines (`ReviewChunkLines = 300`) before dispatching the review agent. Files larger than `ReviewChunkLines` get their own chunk. - -To prevent context-blind review of cross-file changes, the harness runs three passes: - -1. **Establish-context pass (single dispatch, fast tier).** The agent receives the full diff summary (file list + first/last 20 lines of each) and produces a one-paragraph "what this change does and what to watch for" summary. -2. **Per-chunk review pass (parallel, `standard` tier).** Each chunk receives: the establish-context summary as a system-prompt prefix, then its own files. Reviewer findings are accumulated. Parallelism is bounded by `max_agents_by_phase.review`. -3. **Synthesis pass (single dispatch, `standard` tier).** All chunk findings are merged, deduplicated, and prioritised. The synthesis agent decides whether the review should pass, request changes, or block (security/correctness issue). - -The synthesis verdict is what the harness acts on — chunked passes alone never decide. - -### 13.4 Unit archive - -When a slice or milestone reaches `PhaseComplete`, the harness MUST move its artifact directory from `.sf/active/` to `.sf/archive/{YYYY-MM-DD}-{unit-id}/` atomically (rename, not copy+delete). - -`.sf/active/` holds only in-progress work. `.sf/archive/` is queried by `/sf history`. - -### 13.5 Reserved - -(`specs.check`, godoc enforcement on the harness package, is a sf CI requirement — see § 1 — not a runtime gate against user projects.) - ---- - -## 14. Configuration - -> **Status: PARTIAL** — `config-overlay.ts` exists but does not appear to expose the spec's canonical keys (`context_compact_at`, `max_agents_by_phase`, `turn_input_required`, `unit_timeout_by_phase`).

Display the change in `/sf status` as "config drift detected — restart to apply: ". -4. NOT crash and NOT auto-restart. - -### 14.4 Startup validation - -The harness MUST validate config at startup and MUST fail fast with a descriptive error on invalid config. It MUST NOT silently ignore unknown keys or bad values. `/sf doctor` MUST run `HarnessConfig.Validate()` as one of its checks. - -### 14.5 Plan.md format - -Every active unit has a `.sf/active/{unit-id}/plan.md` written by `PhasePlan` and consumed by all subsequent phases. The format is: - -```markdown ---- -unit_id: task/m1/s2/t3 -created_at: 2026-04-29T14:22:00Z -written_by: claude-sonnet-4-6 -plan_version: 1 ---- - -# Goal - - - -# Approach - -<2-3 paragraphs: how the agent intends to do it> - -# Deliverables - -- [ ] -- [ ] <…> - -# Verification - -- -- <…> - -# Notes - - -``` - -The frontmatter `plan_version` increments on each PhaseReassess→Re-plan. Subsequent phases parse the frontmatter to detect plan version changes (informational; not load-bearing). - -The harness MUST validate that `plan.md` parses as Markdown with the required frontmatter fields before allowing a transition out of `PhasePlan`.

Model Routing - -> **Status: EXISTS** — `auto-model-selection.ts`, `benchmark-selector.ts`, `blocked-models.ts`, `llm_task_outcomes` table. - - -### 15.1 Three tiers - -The tier names are fixed: `fast`, `standard`, `reasoning`. Custom tier names are NOT supported — adding a tier would force changes in routing config, complexity-upgrade logic, and the rate-feedback fingerprint, with little benefit. Each tier holds multiple candidate models in `[tiers.]`. The router picks within the tier; it does not change the tier assignment. - -### 15.2 Phase → tier mapping - -Static, config-driven (see § 14.2 `[routing]` table). The harness MUST apply the phase-to-tier mapping before each dispatch. The agent MUST NOT influence this mapping. - -The harness MUST set `Think: true` on the model config for phases mapped to `reasoning` tier. - -### 15.3 Complexity upgrade - -A classifier at dispatch time — file count, scope breadth, cross-cutting changes → complexity score. If the score crosses a configurable threshold, the tier bumps one level (fast→standard, standard→reasoning). The fingerprint and upgrade decision MUST be stored in SQLite for future routing decisions. - -### 15.4 Within-tier selection - -Within a tier, the router picks the model with the highest benchmark score: - -``` -score = quality * 0.6 + (1 - normalised_latency) * 0.2 + (1 - normalised_cost) * 0.2 -``` - -Weights are configurable. If no benchmark data exists for the current fingerprint, use the tier's first model. - -Models with a tripped circuit breaker (§ 9.3) MUST be skipped. - -### 15.5 `/sf rate` feedback loop - -Two signal sources: - -- **Auto-mode** — the agent self-evaluates at unit close: `over` / `ok` / `under` relative to phase objective. No human in the loop. -- **Interactive mode** — human signals `over` / `ok` / `under` after reviewing unit output. - -Both write to `benchmark_results`. Human ratings carry higher weight than LLM self-ratings (configurable multiplier, default 3×). - -Score mappings: `over=0.3` (over-resourced), `ok=0.8`, `under=0.0` (blocks model for this fingerprint). - ---- - -## 16. Knowledge Layer - -> **Status: PARTIAL** — sf has its own local memory layer (`memory-store.ts`, `memory-extractor.ts`, `memory-relations.ts`, `tools/memory-tools.ts`, `bootstrap/memory-tools.ts`, `memories` SQLite table). Spec's Singularity Memory integration is NEW. Decision needed: replace, layer, or drop. - - -### 16.1 Architecture - -The knowledge layer is **Singularity Memory** (`sm`) — an HTTP + MCP server we own at [`singularity-ng/singularity-memory`](https://github.com/singularity-ng/singularity-memory). The engine was derived from [`vectorize-io/hindsight`](https://github.com/vectorize-io/hindsight) (MIT) and assimilated into `singularity_memory_server/` under our namespace; from sf's perspective there is no upstream service. The same `sm` server is shared across our agent fleet (Hermes, OpenClaw, Claude Code, Cursor, sf), so memories accumulate across tools. - -sf uses [`github.com/singularity-ng/singularity-memory-client-go`](https://github.com/singularity-ng/singularity-memory-client-go), auto-generated from the OpenAPI document published by the running sm server (`/openapi.json`). There is no local vector store, no sqlite-vec table, no FTS5 fallback — all retrieval and persistence go through `sm`. - -**Embedded vs remote deployment.** sm supports both modes: - -| Mode | When | Config | -|---|---|---| -| **Embedded** (default for single-user sf) | sm engine runs in-process; no extra service to operate | `[memory] mode = "embedded"` | -| **Remote** | sm runs as a tailnet service shared across multiple tools/users | `[memory] mode = "remote"`, `[memory] url = "http://memory.tailnet.local:7843"` | - -Embedded mode eliminates the network hop for the common case. Switching to remote shares context across the fleet at the cost of a network round-trip per recall. - -SQLite in sf holds **orchestration state only** (sessions, units, blockers, gates, benchmarks, circuit breakers, agents). Memories, learnings, anti-patterns, and codebase context live in Singularity Memory. - -When `sm` is unreachable, the harness MUST log a warning and dispatch with no recall context (plus the local `local_anti_patterns` mirror, § 3.1). The agent still runs; it just lacks historical memory for that session. The harness MUST NOT block dispatch on memory availability. - -**Retain failures queue locally.** PostUnit retain calls that fail (transport error, 5xx) MUST be enqueued in `pending_retain` and retried with exponential backoff on every poll tick until success. This means a unit's learnings are never silently lost to an `sm` outage: - -```sql -CREATE TABLE pending_retain ( - id TEXT PRIMARY KEY, -- ULID - bank TEXT NOT NULL, - payload TEXT NOT NULL, -- serialised retain request - attempts INTEGER NOT NULL DEFAULT 0, - next_retry_at INTEGER NOT NULL, - last_error TEXT, - created_at INTEGER NOT NULL -); -``` - -`pending_retain` rows older than 7 days are flushed to `.sf/archive/lost-learnings.jsonl` and removed; at that point the operator is expected to investigate. - -### 16.1.1 Memory client interface - -The harness uses `github.com/singularity-ng/singularity-memory-client-go` (auto-generated from the sm server's `/openapi.json`) through a thin wrapper that the rest of the codebase depends on. This wrapper is the seam between sf and Singularity Memory; tests substitute a fake. - -```go -type Memory interface { - // Recall fetches top-k entries from a bank for a query. opts.Filter - // may include {"collection": "anti_patterns"} or other tags. - Recall(ctx context.Context, bank string, query string, opts RecallOpts) ([]Entry, error) - - // Retain stores a new entry in a bank. document_id is required for - // upsert-by-content-hash semantics (§ 16.3). - Retain(ctx context.Context, bank string, entry Entry) error - - // Feedback signals helpfulness of an entry recalled in this dispatch. - // signal ∈ {-1, 0, +1}; +1 resets decay timer. - Feedback(ctx context.Context, entryID string, signal int) error - - // Validate marks the entry as still-relevant (resets decay timer). - // Called by PostUnit when a recalled entry directly contributed to success. - Validate(ctx context.Context, entryID string) error - - // Health probe. Used by /sf doctor and the retain queue. - Health(ctx context.Context) error -} - -type RecallOpts struct { - TopK int - Filter map[string]string - RerankQuality string // "fast" | "accurate" -} - -type Entry struct { - DocumentID string // content hash; upsert key - Content string - Tags []string - Metadata map[string]string // includes maturity, decay_factor, etc. - Score float64 // populated on Recall, ignored on Retain -} -``` - -The wrapper is responsible for: -1. Translating sf's `last_error` and gate output into `Entry.Content`. -2. Adding `is_negative` and `collection` tags appropriately. -3. Routing transport errors through `pending_retain` (§ 16.1). -4. Exposing the local `local_anti_patterns` mirror to `Recall` when `sm` is unreachable. - -### 16.2 Memory tiers - -Two tiers prevent token bloat during long-running sessions: - -**Hot cache** — current dispatch's recent turns held in memory (never persisted to SQLite). Configurable size: `[harness] hot_cache_turns = 10`. Cleared on compaction. - -**Singularity Memory store** — durable. PostUnit writes summaries, learnings, and anti-patterns. Pre-dispatch reads top-N most relevant entries. On compaction, the hot cache is summarised and written to Singularity Memory as a `session_summary` entry. - -The harness MUST NOT mix the two tiers. - -### 16.3 Two-bank pattern - -Each session uses two Singularity Memory banks, queried separately and merged before each dispatch: - -```go -projectRecall := sm.Recall("project/"+projectHash, query) -globalRecall := sm.Recall("global/coding", query) -// merge, deduplicate, inject top-N into unit context -``` - -`projectHash` is derived deterministically (so the same project hits the same bank from any machine): - -1. If the project root is a git repository, `projectHash = sha256(canonical_remote_url)[:16]` where canonical_remote_url is the `origin` URL normalised (strip auth, lowercase host, drop trailing `.git`). -2. If no git remote, `projectHash = sha256(absolute_path_with_real_user_home)[:16]`. -3. The resolved hash is cached in `.sf/runtime/project-hash.json` to ensure stability if the remote changes (a cleared cache forces re-derivation; a project move under a different remote is a deliberate re-bank). - -This means a developer cloning the repo on a second machine hits the same Singularity Memory bank as their first machine. Different forks of the same project have different remotes and thus different banks — desired, because their context diverges. - -Concurrent `retain` calls from parallel slice workers use `document_id` derived from content hash. Duplicate memories silently overwrite rather than accumulate. - -### 16.4 Anti-pattern library - -Anti-patterns are memories tagged `collection: anti_patterns`, `is_negative: true`. They: -- Are written explicitly when the agent makes a mistake (gate failure or user feedback). -- MUST NOT be subject to normal maturation decay — they persist at full weight until explicitly removed. -- Are retrieved at dispatch time and presented in a dedicated block: `avoid these mistakes...`. -- MUST also be mirrored to the local `local_anti_patterns` SQLite table (§ 3.1) on `retain`. When Singularity Memory is unreachable, the harness still injects local anti-patterns into prompt context. Anti-patterns are small, high-value, and never decay — making them the one knowledge category worth duplicating locally. - -```go -type AntiPattern struct { - ID string - Description string // what went wrong - Context string // when/where this applies - CorrectPath string // what to do instead - SourceUnit string - CreatedAt time.Time -} -``` - -### 16.5 Pattern maturation - -| State | Condition | Retrieval weight | -|---|---|---| -| `candidate` | < 3 observations | 0.5× | -| `established` | ≥ 3 obs, harmful ratio < 30% | 1.0× | -| `proven` | decayed helpful score ≥ 5, harmful ratio < 15% | 1.5× | -| `deprecated` | harmful ratio > 30% | 0× (excluded) | - -After 3 failed uses, content is prefixed `AVOID:` and flagged `is_negative: true`. - -### 16.6 Confidence decay - -``` -halfLife = 90 * (0.5 + confidence) // days; confidence ∈ [0.0, 1.0] -decayFactor = 0.5 ^ (ageInDays / halfLife) -finalScore = similarityScore * decayFactor -``` - -Memory access tiers: **hot** (accessed within 7 days), **warm** (within 30 days), **cold/stale** (older). - -Entries with 10+ accesses gain a 7-day buffer against decay. Calling `validate()` when a memory directly aids task completion resets the decay timer. - -### 16.7 Retrieval pipeline - -Retrieval is delegated to Singularity Memory via `sm.Recall(bank, query, opts)`. Singularity Memory runs its own internal pipeline — fused semantic + lexical retrieval, optional reranking, and decay weighting — and returns ranked entries. The harness does not implement a retrieval pipeline of its own. - -Recall options the harness uses: - -| Option | Use | -|---|---| -| `top_k` | Number of entries to inject into prompt (default 5) | -| `bank` | `project/{hash}` or `global/coding` (§ 16.3) | -| `filter` | Tag filters (e.g. `collection=anti_patterns`) | -| `rerank_quality` | `fast` (routine) or `accurate` (pre-dispatch context injection) | - -The harness applies its own maturity and anti-pattern weighting (§ 16.4, § 16.5) by tagging entries on retain and filtering / re-ordering on recall — Singularity Memory stores the metadata but does not interpret it. - -### 16.8 `sf init` - -Deep analysis is default, not opt-in: - -1. AST-level codebase scan (languages, structure, entry points, dependencies). -2. Git history analysis (active areas, recent changes, contributors). -3. Retain findings into the `project/{hash}` Singularity Memory bank. -4. Establish `.sf/config.toml` with detected stack, workflow templates, model routing hints. - -`--quick` flag skips Singularity Memory indexing for throwaway sessions. - ---- - -## 17. Persistent Agents - -> **Status: PARTIAL** — sf has ephemeral subagents, including single, -> parallel, chain, and bounded debate batches (`subagent({ mode: "debate", -> rounds, tasks })`; tests include `subagent-agent-discovery`, -> `subagent-model-dispatch`, `agent-end-retry`, `subagent-debate-mode`). -> The spec's persistent-identity + memory-blocks + inbox-wake model is NEW. - - -### 17.1 Agent vs unit - -A **unit** is ephemeral work created by `/sf plan` (or `.sf/plan.md`) and driven through the phase state machine (§ 4). It is archived on completion. - -A **persistent agent** is a named, long-lived identity: it has its own memory blocks, system prompt, and message history. It sleeps at zero cost when idle and wakes when its inbox receives a message or an explicit `/sf agent run ` is issued. - -**A persistent agent run is NOT a unit.** Specifically: - -| Aspect | Unit | Persistent agent run | -|---|---|---| -| Source of work | User goal via `/sf plan` (§ 3.3) | Inbox message or explicit `/sf agent run` | -| Phase state machine | YES | NO | -| Verification gates | YES | NO | -| Workflow templates | YES | NO | -| PostUnit hooks | YES | NO (replaced by `PostAgentRun`) | -| `before_run` / `after_run` workspace hooks | YES | YES (shared lifecycle) | -| Supervisor checks (StuckLoop, AbandonDetect, BudgetWarning) | YES | YES | -| Crash recovery | re-dispatch from last phase | re-deliver undelivered inbox | -| Budget instance | fresh per attempt | persistent across runs (until reset) | - -What they share: the worker attempt lifecycle (§ 6) — workspace creation, `before_run` hook, agent session, turn loop, `after_run` hook — is identical. The supervisor goroutine monitors agent runs and unit attempts with the same checks. The trace records both as runs with distinct `run_kind` attributes. - -### 17.2 Memory block injection - -At dispatch time, the harness MUST render the agent's memory blocks into the system prompt: - -```xml - - {{value}} - {{value}} - {{value}} - -``` - -### 17.3 Built-in memory tools - -| Tool | Signature | Effect | -|---|---|---| -| `core_memory_append` | `(label string, content string)` | Appends content to block, respects `char_limit` | -| `core_memory_replace` | `(label string, old string, new string)` | Replaces substring in block | - -Both tools MUST write to `agent_memory_blocks` in SQLite before the next turn is dispatched. A crash mid-session MUST preserve the updated block state. - -### 17.4 Agent lifecycle - -```go -type AgentState int - -const ( - AgentIdle AgentState = iota // no pending messages, not running - AgentRunning // dispatched, consuming tokens - AgentWaiting // sent a message to another agent, awaiting reply - AgentStopped // explicitly stopped; will not wake automatically -) -``` - -The harness owns all state transitions. The agent loop MUST NOT write `AgentState` directly. - -### 17.5 Agent run termination - -A persistent agent run terminates when ANY of: - -1. **Inbox drained.** The agent's inbox has no `delivered = 0` rows AND the agent's last turn produced no outgoing `send_message` requiring `wait_for_reply`. -2. **Explicit stop.** The agent calls a built-in `stop()` tool, signalling it has no further work. -3. **Budget exhausted.** Per-agent `Budget.AtHardLimit()` fires (§ 8). Compaction does NOT terminate the run; only hard-limit does. -4. **Turn cap.** `max_turns_per_run = 100` (configurable per-agent via `agents.max_turns_per_run` column or `[harness] agent_max_turns_per_run`). Higher than unit cap because agents are long-running. -5. **Supervisor signal.** `SignalAbort` for any reason (StuckLoop, AbandonDetect, ReconciliationCancel does not apply to agents). -6. **Timeout.** A configurable `agent_run_timeout = "30m"` from run start. - -On termination the agent transitions to `AgentIdle` (or `AgentStopped` for case 2). On wake (next inbox message), a NEW run begins — the **agent's hot cache is NOT preserved across runs**; only the durable memory blocks (`agent_memory_blocks`) and message history (`agent_messages`) survive. - -### 17.6 Agent fleet supervision - -Each persistent agent has its own `Budget` instance (§ 8) that persists across runs and is reset only on explicit `/sf agent reset `. Compaction fires per-agent — when one agent's budget hits the compact threshold, only its hot cache is summarised; other agents are unaffected. - -Crash recovery for agents differs from unit recovery (§ 4.7): on restart, each agent's `agent_inbox` is rescanned for `delivered = 0` rows. Any such rows trigger an immediate `AgentWake` — the agent resumes processing the queue. There is no phase to resume; the inbox IS the resumption state. - -The trace records each agent run as a separate root span with `run_kind = "agent"` and `agent_id = `. `/sf session-report` breaks down spend by agent. - ---- - -## 18. Inter-Agent Messaging - -> **Status: NEW** — no `send_message` tool, no `agent_inbox` table, no AgentWake events in sf. - - -### 18.1 `send_message` tool - -```go -// Tool the agent calls: -// send_message(to: string, message: string) -> void -// -// to: agent name or agent ID -// message: plain text; the receiving agent sees it as a "user" role message -``` - -When called, the harness MUST: -1. Insert a row into `agent_inbox` for the target agent. -2. Emit an `AgentWake` pubsub event for the target agent. -3. Record the message in `agent_messages` for both sender and receiver. - -### 18.2 Wake rules - -- An `AgentIdle` agent that receives `AgentWake` MUST start a new dispatch cycle immediately. -- An `AgentRunning` agent queues the message for its next dispatch cycle. -- Undelivered inbox messages MUST be prepended to the context as `user` role messages in arrival order at the start of each dispatch, then marked `delivered = 1`. - -### 18.3 `wait_for_reply` - -An agent calling `wait_for_reply(ticket_id)` transitions to `AgentWaiting`. The harness suspends its dispatch loop until the target agent sends a reply or a configurable timeout elapses. - -`wait_for_reply` has a mandatory timeout. The harness MUST NOT block indefinitely. - -### 18.4 Agent handoff - -`handoff(to, context)` transfers the active task to a specialist agent. `to` is either an agent name (exact match) or a capability tag string (e.g. `"capability:go"` or `"capability:sql,perf"`): - -1. **Resolution.** If `to` starts with `capability:`, the harness queries `agents` for an active agent (`archived_at IS NULL`, `state != 'stopped'`) whose `capabilities` JSON array includes ALL listed tags. If multiple match, the one with the lowest `last_active` wins (round-robin). If none match, `handoff` returns `ErrNoCapableAgent`. -2. **Suspension.** The calling agent's current run is suspended (not completed). -3. **Context delivery.** The target agent receives the full task context (system prompt, memory blocks at handoff time, last N messages) pre-loaded as a snapshot in its inbox. -4. **Wait.** The calling agent transitions to `AgentWaiting` until the specialist replies (subject to `wait_for_reply` timeout). -5. **Fallback.** If the target agent is not found or is `AgentStopped`, `handoff` returns an error and the calling agent continues. - -```go -// Tool the agent calls: -// handoff(to: string, context: string) -> HandoffTicket -// Agent calls wait_for_reply(ticket.id) to block until the specialist responds. -// -// to formats: -// "go-specialist" — exact agent name -// "capability:go" — first eligible agent with capability tag "go" -// "capability:sql,perf" — agent with both "sql" AND "perf" tags -``` - -Capability matching is the recommended form — it lets the agent fleet evolve without changing handoff call sites. - -### 18.5 Append-only inbox log - -`agent_inbox` MUST be append-only. Rows MUST NOT be deleted after insert. `delivered` is the only mutable column. This gives a complete audit trail of all inter-agent communication. - -Inbox and message tables are subject to a periodic GC sweep: rows with `delivered = 1` and `created_at < now() - retain_window` are moved to `.sf/archive/agents/{agent_id}/inbox-{YYYY-MM}.jsonl` and deleted from the live tables. Default `retain_window = 30d`, configurable via `[harness] agent_inbox_retain = "30d"`. The archive is human-readable and queryable by `/sf agent history`. - -### 18.6 Memory block concurrency - -An agent's memory blocks are owned by that agent — they are NEVER shared with other agents (§ 18.7). Within a single agent, a turn's tool calls execute serially (one tool at a time), so two `core_memory_*` writes within a turn cannot race. Across turns, the harness commits the prior turn's writes before dispatching the next turn (§ 17.3). - -`handoff` does NOT share blocks — the receiving agent gets its own blocks. The `context` argument of `handoff` is a snapshot, not a reference. - -### 18.7 What not to build - -- **Shared memory** — agents MUST NOT share memory blocks. If two agents need a common fact, one sends it as a message. -- **Broadcast** — there is no `send_message_all`. Routing MUST be explicit. -- **Synchronous RPC** — `send_message` is fire-and-forget. `wait_for_reply()` is explicit and has a timeout. - ---- - -## 19. Observability - -> **Status: EXISTS** — `activity-log.ts`, `trace-collector.ts`. HTTP API and intent chapters are NEW. - - -### 19.1 Structured log format - -All harness log lines MUST use stable `key=value` pairs. Required context fields: - -| Scope | Required fields | -|---|---| -| Any unit-related log | `unit_id=`, `unit_type=` | -| Agent session lifecycle | `session_id=`, `turn_count=` | -| Phase transitions | `from=`, `to=`, `reason=` | -| Gate execution | `gate=`, `attempt=`, `passed=` | - -Include action outcome in the message: `completed`, `failed`, `retrying`, `canceled`. MUST NOT log large raw payloads — truncate hook output at 2 KB and append `(truncated)`. - -### 19.2 Log rotation - -- Max file size: 10 MB. -- Max rotating files: 5. -- Single-line format — no multi-line log entries. -- When file logging is configured, the default stderr handler MUST be removed (logs to file only). -- Default path: `~/.sf/log/sf.log`. - -### 19.3 Spans and trace - -```go -type Span struct { - TraceID string - SpanID string - Operation string // "tool_call" | "phase_transition" | "model_request" | "hook" - StartedAt time.Time - Duration time.Duration - Attrs map[string]any - Error error -} -``` - -- Every tool call, phase transition, model request, and hook execution MUST emit a span. -- Spans MUST be written to `/.sf/trace/trace-{YYYY-MM-DD}.jsonl` (rolls at local-midnight on first span emission after midnight). -- Span emission MUST be non-blocking — use a buffered channel with a background writer goroutine. -- MUST NOT drop spans. If the buffer is full, block briefly rather than discard. -- The first line of each daily file MUST be a `_meta` record: - ```json - {"_meta":true,"trace_schema_version":1,"sf_version":"","created_at":""} - ``` - Readers branch on `trace_schema_version`. Future schema changes bump the version; no in-place migration of historical files. - -### 19.3.1 Trace index for forensics - -JSONL is the source of truth for spans, but `/sf forensics` queries demand fast access to specific runs/units/sessions. The harness MUST maintain a small SQL index alongside the JSONL: - -```sql -CREATE TABLE trace_index ( - run_id TEXT NOT NULL, - span_id TEXT NOT NULL, - parent_span_id TEXT, - trace_id TEXT NOT NULL, - operation TEXT NOT NULL, -- "tool_call" | "phase_transition" | "model_request" | "hook" - started_at INTEGER NOT NULL, - duration_ms INTEGER, - file_path TEXT NOT NULL, -- which JSONL file holds the full record - file_offset INTEGER NOT NULL, -- byte offset within the file - PRIMARY KEY (run_id, span_id) -); -CREATE INDEX trace_index_started_at ON trace_index(started_at); -CREATE INDEX trace_index_trace_id ON trace_index(trace_id); -``` - -The index is populated by the trace writer goroutine after a successful flush. `/sf forensics ` queries the index, then seeks into the JSONL files for full payloads. - -JSONL files older than 30 days MAY be moved to `/.sf/archive/trace/` by `/sf clean`. The move MUST be a single transaction: -1. Move the JSONL file to `archive/trace/`. -2. UPDATE `trace_index SET file_path = REPLACE(file_path, '.sf/trace/', '.sf/archive/trace/') WHERE file_path = ?`. - -Both steps under a process-level lock so a concurrent forensics query never observes a half-renamed state. If `/sf clean` is interrupted mid-move, on next run it detects the file in archive but index pointing to original path and repairs by re-running the UPDATE. - -### 19.4 Intent chapters - -Spans are grouped into named chapters by intent (not just by phase). - -```go -type Chapter struct { - ID string - UnitID string - Name string // inferred or agent-declared - Intent string // one-sentence summary written at close - OpenedAt time.Time - ClosedAt *time.Time - Outcome string // "success" | "failure" | "pivot" - SpanIDs []string -} -``` - -Chapters serve two purposes: -1. **Context recovery** — on resume after a crash, the harness reconstructs "what the agent was doing and why" from the chapter log. The chapter summary is injected at the top of the restored context. -2. **Singularity Memory recall** — completed chapters are stored as discrete entries. Recall queries match against chapter intent. - -The agent MAY open a chapter explicitly via `chapter_open(name)`. - -### 19.5 HTTP observability API - -The harness MUST expose a lightweight HTTP server on `localhost` when `server.port` is configured. The API is observability-only — orchestrator correctness MUST NOT depend on it. - -**Auth.** The server binds to `127.0.0.1` only. Every request MUST include header `Authorization: Bearer ` where token is read from `/.sf/runtime/api.token` (generated as 32 random bytes hex on first start, mode 0600). Multi-user machines need this — `localhost` alone is insufficient. The actual port and token are written to `/.sf/runtime/server.port` and `api.token` for tools to discover. - -**Session filter.** All endpoints accept `?session=` to scope the response to one session. With no parameter, responses include all active sessions in the project DB; the response body has a top-level `sessions: [...]` array with the snapshot per session. - -**`GET /api/v1/state`** — runtime snapshot: - -```json -{ - "generated_at": "2026-04-29T14:22:00Z", - "counts": { "running": 3, "retrying": 1, "queued": 5 }, - "running": [ - { - "unit_id": "execute-task/m1/s2/t3", - "phase": "execute", - "session_id": "sess-abc-turn-4", - "turn_count": 7, - "last_event": "tool_call", - "started_at": "2026-04-29T14:10:00Z", - "tokens": { "input": 18200, "output": 2100, "total": 20300 } - } - ], - "retrying": [ - { - "unit_id": "execute-task/m1/s2/t4", - "attempt": 2, - "due_at": "2026-04-29T14:24:00Z", - "error": "gate: tests failed" - } - ], - "totals": { - "input_tokens": 84000, - "output_tokens": 12000, - "cost_usd": 1.24, - "seconds_running": 4820 - } -} -``` - -**`GET /api/v1/units/`** — per-unit debug detail: recent events, workspace path, retry count, last error, log file path. - -**`POST /api/v1/refresh`** — queue an immediate poll + reconciliation cycle (202 Accepted; best-effort coalescing of rapid requests). - -### 19.6 Rate-limit tracking - -The harness MUST track the latest rate-limit payload from any provider event and surface it in the TUI and HTTP API. Rate-limit data is observability-only — no retry logic is driven by it. - -**Why not actively throttle on rate limits?** Three reasons: (a) rate limit headers vary in format and meaning across providers (Anthropic's `anthropic-ratelimit-tokens-remaining` vs OpenAI's `x-ratelimit-remaining-tokens` differ in semantics — input-only vs total), (b) the model router (§ 15) already moves between providers, so a single provider's pressure does not need to feed back into dispatch, (c) the circuit breaker (§ 9.3) handles repeated provider failures including 429. Rate-limit data is for the operator to see what's happening, not for the orchestrator to react to. - ---- - -## 20. Failure Taxonomy - -> **Status: PARTIAL** — `src/resources/extensions/sf/errors.ts` exists; full spec error code set needs cross-check against actual codes. - - -Every harness failure has a class. The class determines recovery behavior. - -| Class | Examples | Recovery | -|---|---|---| -| `config` | Missing or invalid `.sf/workflows/*.toml`, invalid `.sf/config.toml`, missing API key | Block new dispatches. Keep service alive. Emit operator-visible error. | -| `workspace` | Directory creation failure, hook timeout, invalid path | Fail the current attempt. Orchestrator retries with backoff. | -| `agent_session` | Startup handshake failed, turn timeout, turn cancelled, subprocess exit, stalled session, `turn_input_required` (hard mode) | Fail the current attempt. Orchestrator retries with backoff. | -| `observability` | Snapshot timeout, dashboard render error, log sink failure | Log and ignore. MUST NOT crash the orchestrator over an observability failure. | - -### 20.1 Typed error codes - -```go -const ( - ErrMissingWorkflowFile = "missing_workflow_file" // .sf/workflows/.toml not found - ErrWorkflowParseError = "workflow_parse_error" - ErrWorkspaceCreation = "workspace_creation_failed" - ErrWorkspaceSymlinkEscape = "workspace_symlink_escape" - ErrHookTimeout = "hook_timeout" - ErrHookFailed = "hook_failed" - ErrAgentStartup = "agent_session_startup" - ErrTurnTimeout = "turn_timeout" - ErrTurnFailed = "turn_failed" - ErrTurnInputRequired = "turn_input_required" - ErrPromptRender = "prompt_render_failed" - ErrBudgetExhausted = "budget_exhausted" - ErrStalled = "stalled" - ErrCanceledByOperator = "canceled_by_operator" // user ran /sf abandon - ErrModelUnavailable = "model_unavailable" - ErrCircuitOpen = "circuit_open" - ErrNoCapableAgent = "no_capable_agent" - ErrSshDisconnected = "ssh_disconnected" - ErrCanceledBySupervisor = "canceled_by_supervisor" -) -``` - -Implementations MUST match on typed error codes. Matching on error message strings is PROHIBITED. - -### 20.2 Scheduler state - -Scheduler state is intentionally in-memory. Restart recovery MUST NOT attempt to restore retry timers, live sessions, or in-flight agent state. After restart: startup terminal cleanup → fresh poll → re-dispatch eligible work. This is a design choice, not a limitation. Durable retry state is a future extension. - ---- - -## 21. Trust Boundary - -> **Status: PARTIAL** — `auto_approve` config key not found verbatim. PreToolUse hooks exist via pi-coding-agent. Auto-approve allowlist needs to be made explicit. - - -Every deployment MUST document its trust posture explicitly. There is no universal safe default. - -### 21.1 Default posture (single-user developer machine) - -- Auto-approve tool execution and file changes within the workspace. -- `turn_input_required = "soft"`. -- Workspace isolation enforced (symlink-aware path containment, sanitized names). -- Secrets from Vault only — MUST NOT store secrets in config files in plaintext. - -### 21.2 Hardening measures for less-trusted environments - -- Filter which issues/tasks are eligible for dispatch — untrusted or out-of-scope tasks MUST NOT automatically reach the agent. -- Restrict the `plan_unit` client-side tool to read-only or scope-limited mutations only. -- Run the agent subprocess under a dedicated OS user with no write access outside the workspace root. -- Add container or VM isolation around each workspace (Docker, nsjail, etc.). -- Restrict network access from the workspace. -- Narrow available tools to the minimum needed for the workflow. - -### 21.3 Auto-approval contract - -In auto-mode the harness calls pi-coding-agent's existing permission API ONLY for operations listed in `[harness.auto_approve]`. Sensitive operations (`fs:write-outside-project`, `shell:exec`) MUST always prompt regardless of auto-mode setting. - -**Precedence between PreToolUse hooks and auto-approve.** pi-coding-agent's PreToolUse hook system already runs before any tool call. If a PreToolUse hook returns `deny` or `halt`, the tool call is rejected even if `auto_approve` lists the tool. The order is: - -1. PreToolUse hooks run first; their decision is final for `deny`/`halt`. -2. If hooks return `allow` or no decision, the auto-approve list is consulted. -3. If neither approves, the user is prompted (interactive mode) or the call fails (auto-mode for non-allowlisted tools). - -This means: PreToolUse hooks MAY revoke an auto-approval; the auto-approve list MAY NOT override a hook denial. This precedence is critical for security policies that need to override per-session approvals. - -SF-specific permission gates: -- `git:write` — any git operation that mutates state. Requires explicit grant in auto-mode. -- `worktree:create` and `worktree:delete` — worktree lifecycle. -- `fs:write-outside-project` — ALWAYS prompt, NEVER auto-approve. -- `shell:exec` — allowlist specific commands; no blanket approval. - ---- - -## 22. Distributed Execution - -> **Status: NEW** — no SSH worker code found in sf. - - -### 22.1 Topology - -The orchestrator ALWAYS runs centrally. Workers MAY execute on remote hosts over SSH. - -```toml -[worker] -ssh_hosts = ["mikki-bunker", "forge-gpu-1"] -max_concurrent_agents_per_host = 3 -``` - -### 22.2 Rules - -- `workspace.root` is resolved on the **remote host**, not the orchestrator. -- The agent subprocess is launched over SSH stdio. The orchestrator owns the session lifecycle. -- Continuation turns within one worker lifetime MUST stay on the same host and workspace. -- If a host is at capacity, dispatch MUST wait rather than silently fall back to local or another host. -- Once a run has produced side effects, moving to another host on retry is treated as a new attempt (not invisible failover). -- The run record MUST include `worker_host` so operators can see where each run executed. -- SSH workspace creation MUST use the same symlink-aware validation as local workspaces, implemented via shell script. - -### 22.3 Disconnect and zombie handling - -When the SSH connection drops mid-turn: - -1. The orchestrator marks the attempt `failed` with `error_code = "ssh_disconnected"` after `[worker] ssh_disconnect_timeout = "30s"` of no stdio activity. -2. **Before** scheduling a retry, the orchestrator MUST emit a remote-cleanup script over a fresh SSH session: `pgrep -f "" | xargs -r kill -TERM`, wait 10s, then `kill -KILL`. The marker is a unique string injected into the agent process's command line (e.g. `--sf-run-id=`). -3. If the cleanup script fails (host unreachable), the host is marked `unhealthy` for `[worker] host_quarantine = "5m"`. New dispatches skip it; the host re-eligibility check runs each tick. -4. The retry MUST land on a different host if `host_quarantine` is in effect for the original host; otherwise same host with a fresh workspace re-creation (the previous workspace is moved to `~/.sf/orphaned-workspaces/{timestamp}-{run-id}/` for forensics, not deleted). - -Zombies are the dominant failure mode for distributed execution; ignoring them produces double-write corruption. - ---- - -## 23. Plugin Extension Points - -> **Status: NEW** — no `Shipper`/`VCS`/`Notifier` interfaces. sf has its own command/extension model that may need to be reconciled with this spec. - - -Plugin interfaces are TypeScript classes implementing the listed contracts. sf loads them via dynamic import at boot from `.sf/plugins/`. Each plugin is a Node module exporting a default class with a marker method (e.g. `static readonly kind = "shipper"`). - -### 23.1 Interfaces - -**`SupervisorCheck`** — custom supervisor checks without forking: - -```go -type SupervisorCheck interface { - Name() string - Check(ctx context.Context, state SupervisorState) SupervisorSignal -} -``` - -**`Shipper`** — PR/MR creation. GitHub default; GitLab, Gitea, Forgejo alternatives: - -```go -type Shipper interface { - Ship(ctx context.Context, opts ShipOptions) (ShipResult, error) -} -``` - -**`VCS`** — version control backend. `git` default; `jj` (Jujutsu) first alternative: - -```go -type VCS interface { - Commit(ctx context.Context, msg string, files []string) error - Branch(ctx context.Context, name string) error - Push(ctx context.Context, remote, branch string) error -} -``` - -**`Store`** — storage backend. SQLite for personal use; PostgreSQL for team sessions: - -```go -type Store interface { - SaveSession(ctx context.Context, s Session) error - LoadSession(ctx context.Context, id string) (Session, error) - SaveMemory(ctx context.Context, m Memory) error - SearchMemory(ctx context.Context, q MemoryQuery) ([]Memory, error) -} -``` - -**`Notifier`** — notification provider. Slack, Discord, webhook: - -```go -type Notifier interface { - Notify(ctx context.Context, event Event) error -} -``` - -### 23.2 What stays out of plugins - -- Workflow templates — enforced TOML/YAML data -- Skills — `SKILL.md` prompt guidance -- Model routing — config + SQLite + thin Go scorer -- Phase transitions — harness-owned, not extensible - ---- - -## 24. Secret Management - -> **Status: NEW** — no `vault://` resolver found in sf. - - -### 24.1 `vault://` URI scheme - -Secrets MUST NOT be stored in config files in plaintext. The canonical secret reference format is: - -``` -vault://secret/sf#anthropic_api_key -``` - -In config: - -```json -{ - "providers": { - "anthropic": { "api_key": "vault://secret/sf#anthropic_api_key" } - } -} -``` - -### 24.2 VaultResolver - -```go -type VaultResolver struct { - client *vault.Client -} - -func (r *VaultResolver) Resolve(uri string) (string, error) { - // parse vault://path#field - // client.KVv2(mount).Get(ctx, path) → secret.Data["field"] -} -``` - -Auth chain (first that succeeds): -1. `VAULT_TOKEN` env var (CI / ephemeral) -2. `~/.vault-token` file (local dev) -3. AppRole via `VAULT_ROLE_ID` + `VAULT_SECRET_ID` (production) - -Secrets MUST be fetched once at startup and held in memory for the session lifetime. MUST NOT be written to disk or logged. - -### 24.3 Stopgap - -Until the native resolver is built, sf supports the same `$(command)` substitution that pi-mono inherits — embed a shell command: - -```json -{ "api_key": "$(vault kv get -field=anthropic_api_key secret/sf)" } -``` - ---- - -## 25. CLI Commands - -> **Status: PARTIAL** — 22 `commands-*.ts` files cover most spec commands but some are named differently (e.g. `commands-do.ts` vs spec's `/sf next`). Full mapping table needed. - - -### `/sf plan "" [--workflow=feature] [--link-issue=]` - -Add a milestone to the project's plan. sf decomposes into slices and tasks at runtime (Plan phase) but the milestone row is created immediately so it shows up in `/sf status`. `--link-issue=` writes `metadata.gh_issue` for use by visibility hooks (§ 10.5.1). `--workflow=` overrides the default workflow template. - -### `/sf plan reload` - -Re-read `.sf/plan.md` and reconcile against current `units`. Adds new milestones, surfaces removed ones as `archived`, leaves in-flight units alone. - -### `/sf abandon "reason"` - -Operator override to mark a unit terminal mid-flight. Sets `phase_status = 'canceled'`, records the reason in `runs.error_code = "canceled_by_operator"`. Mid-turn workers detect the change at the next inter-turn check (§ 6) and exit cleanly. - -### `/sf auto` - -Start the autonomous loop. The harness polls `units` for eligible work and dispatches workers until no more eligible units exist or until stopped by `/sf pause`. - -### `/sf next` - -Manual step mode. Dispatch one unit, wait for completion, surface result. Repeat on each invocation. - -### `/sf dispatch ` - -Force-dispatch a specific unit regardless of priority or blocker state. Surfaces a warning if blockers exist. - -### `/sf pause` - -Cleanly pause auto-mode. Writes `SessionPaused` to SQLite. All in-flight units complete their current turn before stopping. - -### `/sf status` - -Structured project health snapshot: - -``` -Project: singularity-foundry -Phase: Execute [m2/s3/t1 — add trace export] -Next: TDD [m2/s3/t1] -Blocker: none - -Milestones: 2 / 5 (40%) -Slices: 7 / 18 (39%) -Tasks: 14 / 42 (33%) - -Session: 4h 12m | $0.83 | claude-sonnet-4-6 -``` - -Blockers surface from the `session_blockers` table. `/sf status` MUST NOT poll pubsub — it reads SQLite directly. - -### `/sf revert ` - -Four-phase git-aware revert protocol: - -1. **Target selection** — accept explicit unit ID, or present the top 3 in-progress + 3 most recent completed units as a numbered menu. -2. **Git reconciliation** — find all commits belonging to the target unit. Handle ghost commits (SHA missing after rebase/squash) by searching by commit message prefix. -3. **Confirmation** — display exact SHA list with descriptions and dates. Warn on merge commits. -4. **Execution** — `git revert --no-edit ` in reverse order (newest first). On conflict: `SignalPause`. - -After all reverts: restore `.sf/active/{unit-id}/` artifacts from archive; mark unit as `[ ]` in the plan. - -### `/sf rate over|ok|under [unit-id]` - -Signal model quality. Without `unit-id`, targets the most recently completed run in the current session — specifically the latest row in `runs` where `outcome IN ('success', 'failure')` and `ended_at IS NOT NULL`, scoped to `session_id`. With `unit-id`, targets the latest run for that unit. - -Writes to `benchmark_results` with the human-rating weight multiplier (default 3×). Cannot be issued against an in-flight run. - -### `/sf benchmark` - -Run on-demand model benchmarks for all tiers against real task samples. Updates `benchmark_results`. - -### `/sf doctor` - -Run health checks: -- `HarnessConfig.Validate()` -- Vault connectivity -- Singularity Memory connectivity -- SQLite schema version -- Lock file state -- Workflow template syntax -- HTTP API token presence + permissions - -Exit code: `0` if all checks pass, `1` if any FAIL or WARN. Useful in CI: `sf doctor || exit 1`. The TUI rendering shows pass/warn/fail per check; the JSON form (`/sf doctor --json`) returns a structured report for automation. - -### `/sf history` - -Query archived units in `.sf/archive/`. Supports filtering by date, phase, model, verdict. - -### `/sf forensics` - -Inspect the trace for a specific unit or session. Shows all spans, tool calls, phase transitions, and gate results in chronological order. - -### `/sf reset-circuits` - -Clear all tripped circuit breakers. Next dispatch uses benchmark scores to select within each tier normally. - -### `/sf reassess-resolve "operator response"` - -Resume a unit that entered `PhaseReassess` with the **Escalate** outcome (§ 4.6). The operator's response is appended as the next attempt's `last_error` so the agent can incorporate it. The unit re-enters `PhasePlan`. - -### `/sf force-clear ` - -Operator override: mark a `session_blockers` row resolved with `resolved_by = "/sf force-clear"`. Used to dismiss stuck `GateBlocked` events that can't auto-resolve (e.g. flaky external test infrastructure). - -### `/sf merge-resolve ` - -Resume a unit halted on `MergeConflict`. Assumes the operator has resolved the conflict in the worktree. Triggers re-emission of `MergeReady`. - -### `/sf uat-approve ` and `/sf uat-reject "reason"` - -Advance a unit out of `PhaseUAT` (§ 4.6). Approve transitions to `PhaseMerge`; reject transitions to `PhaseReassess` with the reason as `last_error`. - -### `/sf agent ` - -Persistent agent management: - -- `/sf agent list` — show all agents with state, last_active, capabilities. -- `/sf agent run "message"` — wake an agent with an ad-hoc message (bypasses inbox routing). -- `/sf agent reset ` — clear hot cache and reset Budget; memory blocks and message history preserved. -- `/sf agent delete ` — soft-delete (sets `archived_at`); runs and messages preserved via snap_ columns. -- `/sf agent inspect ` — show memory blocks, recent messages, current state. -- `/sf agent history ` — query archived inbox in `.sf/archive/agents/{id}/`. - -### `/sf history [filters]` - -Query archived units in `.sf/archive/`. Filter syntax: - -``` -/sf history --since 2026-04-01 --phase merge --verdict success -/sf history --workflow spike -/sf history --model claude-sonnet-4-6 --limit 50 -/sf history --json # machine-readable output for automation -``` - -Filters are AND-combined.
