From eb302fe1d2cf8ce734b2147d189714efa8b42d01 Mon Sep 17 00:00:00 2001 From: Jeremy McSpadden Date: Mon, 16 Mar 2026 16:54:09 -0500 Subject: [PATCH 1/8] feat: parallel milestone orchestration foundation (#672) Add infrastructure for parallel milestone execution behind `parallel.enabled: false` flag (opt-in, zero impact to existing users). New modules: - session-status-io.ts: File-based IPC protocol with atomic writes, signal lifecycle (pause/resume/stop), and stale session detection - parallel-eligibility.ts: Milestone parallelism analysis checking dependency satisfaction and file overlap across slice plans - parallel-orchestrator.ts: Core orchestrator managing worker lifecycle, budget tracking, and coordination via session status files - /gsd parallel [start|status|stop|pause|resume] command handlers Modified: - types.ts: ParallelConfig interface (enabled, max_workers, budget_ceiling, merge_strategy, auto_merge) - preferences.ts: Parallel config validation, merging, and resolver - commands.ts: /gsd parallel subcommand routing with argument completions Tests: 39 new tests covering session I/O roundtrip, signal lifecycle, stale detection, eligibility formatting, orchestrator lifecycle, budget enforcement, and preference validation. --- ...ue-672-parallel-milestone-orchestration.md | 17 + src/resources/extensions/gsd/commands.ts | 97 +++- .../extensions/gsd/parallel-eligibility.ts | 233 +++++++++ .../extensions/gsd/parallel-orchestrator.ts | 308 ++++++++++++ src/resources/extensions/gsd/preferences.ts | 62 +++ .../extensions/gsd/session-status-io.ts | 197 ++++++++ .../gsd/tests/parallel-orchestration.test.ts | 455 ++++++++++++++++++ src/resources/extensions/gsd/types.ts | 13 + 8 files changed, 1380 insertions(+), 2 deletions(-) create mode 100644 .plans/issue-672-parallel-milestone-orchestration.md create mode 100644 src/resources/extensions/gsd/parallel-eligibility.ts create mode 100644 src/resources/extensions/gsd/parallel-orchestrator.ts create mode 100644 src/resources/extensions/gsd/session-status-io.ts create mode 100644 src/resources/extensions/gsd/tests/parallel-orchestration.test.ts diff --git a/.plans/issue-672-parallel-milestone-orchestration.md b/.plans/issue-672-parallel-milestone-orchestration.md new file mode 100644 index 000000000..1dc88e601 --- /dev/null +++ b/.plans/issue-672-parallel-milestone-orchestration.md @@ -0,0 +1,17 @@ +# Issue #672: Parallel Milestone Orchestration + +**Issue:** https://github.com/gsd-build/gsd-2/issues/672 +**Contributor:** @deseltrus (7 merged PRs, proven contributor) +**Status:** WIP — foundation modules built, orchestrator core in progress +**Default:** `parallel.enabled: false` — opt-in, zero impact to existing users + +## Delivery Plan (6 PRs) + +### PR 1: Worktree Bugfixes - MERGED (#675) +### PR 2: Dispatch Hardening (Small) - pending contributor +### PR 3: Parallel Config + Preferences (Small) - included in this PR +### PR 4: Session Status Protocol (Medium) - included in this PR +### PR 5: Orchestrator Core (Large) - included in this PR +### PR 6: Dashboard + Commands (Medium) - commands included, dashboard deferred + +See full plan in the GitHub issue comment. diff --git a/src/resources/extensions/gsd/commands.ts b/src/resources/extensions/gsd/commands.ts index 76229dfcf..b25d52f2a 100644 --- a/src/resources/extensions/gsd/commands.ts +++ b/src/resources/extensions/gsd/commands.ts @@ -42,6 +42,13 @@ import { handleQuick } from "./quick.js";

From 0ee7016bc7816a0e95b96df0a1bd855fef3845c8 Mon Sep 17 00:00:00 2001 From: Jeremy McSpadden Date: Mon, 16 Mar 2026 17:17:12 -0500 Subject: [PATCH 7/8] feat: add dashboard parallel workers view, 80% budget alert, and E2E tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add three remaining features: 1. Dashboard multi-session view: New worker registry (subagent/worker-registry.ts) tracks active parallel subagent sessions with batch grouping and status lifecycle. Dashboard overlay now renders a "Parallel Workers" section showing per-batch worker status with agent names, task previews, and elapsed time. 2. Budget approach notification at 80%: Added 80% threshold to the existing 75/90/100 budget alert levels. Fires an "Approaching budget ceiling" notification with desktop alert at the 80% mark, giving users earlier warning before hitting enforcement thresholds. 3. End-to-end testing across milestones: New E2E test validates parallel worker lifecycle across M001/M002 milestones, metrics accumulation, full budget alert progression (0→75→80→90→100), cost prediction with multi-milestone data, and combined worker+budget scenarios. Worker registry unit tests cover registration, batch grouping, status updates, and edge cases. --- src/resources/extensions/gsd/auto.ts | 7 +- .../extensions/gsd/dashboard-overlay.ts | 38 ++ .../gsd/tests/auto-budget-alerts.test.ts | 23 +- ...rallel-workers-multi-milestone-e2e.test.ts | 354 ++++++++++++++++++ .../gsd/tests/worker-registry.test.ts | 148 ++++++++ src/resources/extensions/subagent/index.ts | 5 + .../extensions/subagent/worker-registry.ts | 99 +++++ 7 files changed, 670 insertions(+), 4 deletions(-) create mode 100644 src/resources/extensions/gsd/tests/parallel-workers-multi-milestone-e2e.test.ts create mode 100644 src/resources/extensions/gsd/tests/worker-registry.test.ts create mode 100644 src/resources/extensions/subagent/worker-registry.ts diff --git a/src/resources/extensions/gsd/auto.ts b/src/resources/extensions/gsd/auto.ts index 9da662382..df1d565bb 100644 --- a/src/resources/extensions/gsd/auto.ts +++ b/src/resources/extensions/gsd/auto.ts @@ -362,11 +362,12 @@ let _sigtermHandler: (() => void) | null = null; */ const inFlightTools = new Map(); -type BudgetAlertLevel = 0 | 75 | 90 | 100; +type BudgetAlertLevel = 0 | 75 | 80 | 90 | 100; export function getBudgetAlertLevel(budgetPct: number): BudgetAlertLevel { if (budgetPct >= 1.0) return 100; if (budgetPct >= 0.90) return 90; + if (budgetPct >= 0.80) return 80; if (budgetPct >= 0.75) return 75; return 0; } @@ -2233,6 +2234,10 @@ async function dispatchNextUnit( lastBudgetAlertLevel = newBudgetAlertLevel; ctx.ui.notify(`Budget 90%: ${formatCost(totalCost)} / ${formatCost(budgetCeiling)}`, "warning"); sendDesktopNotification("GSD", `Budget 90%: ${formatCost(totalCost)} / ${formatCost(budgetCeiling)}`, "warning", "budget"); + } else if (newBudgetAlertLevel === 80) { + lastBudgetAlertLevel = newBudgetAlertLevel; + ctx.ui.notify(`Approaching budget ceiling — 80%: ${formatCost(totalCost)} / ${formatCost(budgetCeiling)}`, "warning"); + sendDesktopNotification("GSD", `Approaching budget ceiling — 80%: ${formatCost(totalCost)} / ${formatCost(budgetCeiling)}`, "warning", "budget"); } else if (newBudgetAlertLevel === 75) { lastBudgetAlertLevel = newBudgetAlertLevel; ctx.ui.notify(`Budget 75%: ${formatCost(totalCost)} / ${formatCost(budgetCeiling)}`, "info"); diff --git a/src/resources/extensions/gsd/dashboard-overlay.ts b/src/resources/extensions/gsd/dashboard-overlay.ts index 953c97130..f06629f7b 100644 --- a/src/resources/extensions/gsd/dashboard-overlay.ts +++ b/src/resources/extensions/gsd/dashboard-overlay.ts @@ -19,6 +19,7 @@ import { } from "./metrics.js"; import { loadEffectiveGSDPreferences } from "./preferences.js"; import { getActiveWorktreeName } from "./worktree-command.js"; +import { getWorkerBatches, hasActiveWorkers, type WorkerEntry } from "../subagent/worker-registry.js"; function formatDuration(ms: number): string { const s = Math.floor(ms / 1000); @@ -363,6 +364,43 @@ export class GSDDashboardOverlay { lines.push(blank()); } + // Parallel workers section — shows active subagent sessions + if (hasActiveWorkers()) { + lines.push(hr()); + lines.push(row(th.fg("text", th.bold("Parallel Workers")))); + lines.push(blank()); + + const batches = getWorkerBatches(); + for (const [batchId, workers] of batches) { + const running = workers.filter(w => w.status === "running").length; + const done = workers.filter(w => w.status === "completed").length; + const failed = workers.filter(w => w.status === "failed").length; + const total = workers[0]?.batchSize ??
