- Stream tool results in real-time during Claude Code SDK sessions
instead of deferring until session end. Tool calls (read, bash, write,
etc.) now show their output as they complete, not collapsed as "..."
- Stop suppressing toolcall_start/delta/end events from stream adapter
so the TUI can render tool call progress during streaming
- On SDK turn boundary (user message with tool results), push synthetic
toolcall_end events with externalResult attached for immediate rendering
- Chat controller checks for externalResult on toolcall_end message
updates and calls updateResult on pending ToolExecutionComponents
- Fix case-sensitive tool name matching (Read vs read, Bash vs bash)
in TUI ToolExecutionComponent rendering
- Auto-discover and pass GSD_WORKFLOW_EXECUTORS_MODULE and
GSD_WORKFLOW_WRITE_GATE_MODULE env vars in MCP server launch config
- Add /gsd mcp init command and auto-bootstrap .mcp.json for Claude
Code provider during auto-start
- Add tool_execution_update event type for web UI streaming updates
- Add setStderrLoggingEnabled toggle for workflow logger
The schema overload detector counted ALL isError tool results toward the
consecutive-failure cap, including bash commands that returned non-zero exit
codes (e.g. rg/grep exit 1 = 'no matches'). Three consecutive exploratory
searches with no matches would trigger the cap and abort the session.
Root cause: the allToolsFailed check used toolResults.every(r => r.isError)
which conflates preparation-phase errors (schema validation, tool-not-found,
tool-blocked) with execution-phase errors (the tool ran successfully but
returned a non-zero exit code).
Fix: track preparationErrorCount alongside tool results. Only preparation
errors (schema/validation failures) increment the consecutive failure
counter. Tool execution errors — like bash exit code 1 — are valid usage
and do not count toward the cap.
Also fixes pre-existing StopReason type mismatches in agent-loop tests
(end_turn → stop, tool_use → toolUse).
* fix: cap consecutive tool validation failures to prevent stuck-loop (#2783)
When the LLM repeatedly emits tool calls with arguments that fail schema
validation, the agent loop retries indefinitely — each failed validation
returns an error tool result, the LLM retries with the same broken args,
and the cycle burns budget with no progress.
Add a consecutive-failure counter in runLoop that tracks turns where ALL
tool calls fail. After MAX_CONSECUTIVE_VALIDATION_FAILURES (3) consecutive
all-error turns, the loop emits a diagnostic stop message and terminates
cleanly. The counter resets whenever any tool call in a turn succeeds, so
intermittent failures do not trigger early termination.
Closes#2783

* chore: retrigger CI
* fix(test): repair agent-loop.test.ts — close unclosed blocks, merge imports
Two test suites were concatenated without closing the first suite's
it+describe blocks, placing the second suite's imports inside a function
body and triggering 'Unexpected "{" ' from esbuild. Merged into a single
well-structured file with consolidated imports and proper closings.

Map pause_turn to "pauseTurn" instead of "stop" so the agent loop
continues when Anthropic's server pauses a long-running turn (e.g.
native web search hitting its iteration limit). Previously the
incomplete server_tool_use block was saved to history, causing a
400 invalid_request_error on the next API call.

- Add insertChildBefore() to Box component for positional insertion
- In chat controller, insert tool_execution components before the last
assistant message component (instead of appending after) when tools
were executed externally
- Simplify agent-loop externalToolExecution path back to basic
tool_execution_start/end emission
- Toolcall streaming events are filtered in the Claude Code adapter
to prevent duplicate rendering via message_update
Result: externally-executed tool calls render above the text response,
matching the expected visual flow.

Adds `externalToolExecution` flag to AgentLoopConfig. When true, the
agent loop emits tool_execution_start/end events for TUI rendering but
skips local tool dispatch. Used by providers that handle tool execution
internally (e.g., Claude Code CLI via Agent SDK).
The flag is dynamically evaluated per-loop via a callback on
AgentOptions, so model switches mid-session are handled correctly.
Providers with authMode "externalCli" automatically use this mode.
Also updates the Claude Code CLI stream adapter to preserve tool call
blocks in the final message instead of stripping them.

- blob-store: Replace non-atomic check-then-act (existsSync + writeFileSync)
with writeFileSync using 'wx' flag for atomic exclusive creation
- discovery-cache: Re-read from disk before mutations to avoid stale overwrites,
and use temp file + rename for atomic saves
- agent-loop: Deep copy messages array in agentLoopContinue to prevent shared
reference mutations from affecting the original context
* fix(footer): display active inference model instead of configured model (#1844)
The footer read state.model which updates immediately on model selection,
but the running agent loop captures the model at _runLoop() start time.
This caused the footer to show the wrong model when the user switched
models mid-inference.
Add activeInferenceModel to AgentState, set it when _runLoop begins, and
clear it when the loop ends. The footer now prefers activeInferenceModel
over model, so it always shows the model actually being used for the
current inference.
Bug 2 follow-up to PR #1975 which fixed Bug 1 (queued messages cancel
tool calls).

* ci: retrigger after stale check
* fix(test): rewrite agent test to use structural assertions
The mock StreamFn returned a plain AsyncGenerator but
AssistantMessageEventStream requires additional properties,
causing CI build failure. Rewrote tests as source-verification
assertions (matching other GSD test patterns) and excluded
test files from tsconfig build.

When a user presses Escape during streaming, the abort flow clears all
queued messages indiscriminately. User messages typed during streaming
are silently discarded. This adds a QueueEntry wrapper in the Agent class
to track message origin ("user" vs "system"), so that clearQueue() can
preserve user-typed messages while discarding system-generated ones.

* feat: render native web search tool calls in TUI
The Anthropic streaming parser silently dropped server_tool_use and
web_search_tool_result content blocks, making native web search
invisible. Add ServerToolUseContent and WebSearchResultContent types,
handle both block types in the streaming parser and conversation replay,
and render them as ToolExecutionComponent in the interactive TUI.

* fix: skip non-toolCall blocks in Mistral provider conversation replay

Moves extension tool_call/tool_result interception from wrapToolsWithExtensions
(which fires inside the agent loop, bypassing event settlement) to
beforeToolCall/afterToolCall hooks that await _agentEventQueue. This ensures
extensions always see settled state — including the appended assistant message —
even when tools execute in parallel.

Vendor all 4 Pi packages (tui, ai, agent-core, coding-agent) from
pi-mono v0.57.1 as @gsd/* workspace packages under packages/. This
replaces the compiled npm dependency (@mariozechner/pi-coding-agent)
and patch-package workflow, giving direct source access for
modifications.
- Copy Pi source from pi-mono v0.57.1 into packages/
- Create workspace package.json + tsconfig.json for each package
- Rename ~240 imports from @mariozechner/pi-* to @gsd/pi-*
- Apply existing patches as source edits (setModel persist, VT input)
- Remove @mariozechner/pi-coding-agent dep and patch-package
- Update build pipeline to build packages in dependency order
- Add pi-upstream git remote for future selective syncing
