Refs #348 (chain 1 of 2; the closing keyword lands in chain PR 2)

PR Type

  • Bug fix
  • New feature
  • Documentation only
  • Code refactoring
  • Maintenance/tooling
  • Breaking change

Label request: type:chore (test-type commit per the org type mapping; this fork PR cannot self-label)

Summary

  • Deterministic runtime repro of the fix(orchestrator): enforce inline skill output contracts #348 gap on unmodified main: a registry-indexed project skill with an ## Output Contract is discoverable and indexed, but the composed parent prompt binds only subagents to the exact SKILL.md read; no parent-inline read obligation exists and the contract body never reaches parent context.
  • Offline harness per tests/asset-installation-runtime.test.ts: scoped-env child boots the real SDK session (no network, in-memory settings), forces /skill-registry:refresh, and captures the composed parent prompt via __testing.buildGentlePrompt with a fidelity pin proving the render went through the composition pipeline.
  • The two gap assertions are guarded flip helpers, so chain PR 2 (the fix) inverts them with minimal edits.

Changes Table

File Change
tests/orchestrator-inline-skill-execution.test.ts New: offline runtime repro (1 test; passes on unmodified main as the gap baseline)

Test Plan

  • node --experimental-strip-types --test tests/orchestrator-inline-skill-execution.test.ts — 1/1 pass (gap proven on main)
  • Neighbor suites green: orchestrator-budget 38/38, skill-registry 17/17
  • Full-suite attribution: the cancelled cluster in tests/inprocess-reviewer.test.ts (26 cancelledByParent) reproduces on clean main without this change; pre-existing, not a regression (same class as the macOS failure noted in fix(orchestrator): enforce inline skill output contracts #349)

Contributor Checklist

  • Linked an approved issue (Refs #348, status:approved)
  • Exactly one type:* label — requested above (fork PR cannot self-label)

  • Skills load correctly in target agent (n/a — test-only PR)

Summary by CodeRabbit

  • Tests
    • Added offline regression coverage for project skills, verifying that skill metadata and paths remain available in the project index without including skill body text in the parent prompt.
    • Added checks that prompt composition directs subagents to read skill files without requiring the parent to do so, and that indexing and prompt composition can be verified without starting a model turn.

…entleman-Programming#348)

Deterministic baseline for issue Gentleman-Programming#348 on unmodified main: a project skill
with an ## Output Contract is indexed by the skill registry, yet the
composed parent prompt binds only subagents to read the exact indexed
SKILL.md. No parent-inline read obligation exists and the contract body
never reaches parent context, so contract markers cannot reach
parent-inline results.

Offline runtime harness per tests/asset-installation-runtime.test.ts:
scoped-env child boots the real SDK session (no network, in-memory
settings), forces /skill-registry:refresh, asserts indexing, then
captures the composed parent prompt via __testing.buildGentlePrompt with
a fidelity pin proving the render went through the composition pipeline.

The two gap assertions are guarded flip helpers for the fix slice.

📝 Walkthrough

Walkthrough

This change adds an offline integration test for skill registry indexing and parent prompt composition. It verifies that the registry indexes the project skill without including its contract marker, and that the parent prompt retains the subagent-directed read clause without an inline-read obligation or the marker.

Changes

Systems and components

  • observed — tests (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

  • observed — Modified behavior in tests/orchestrator-inline-skill-execution.test.ts: Adds the new offline integration test file: imports Node built-ins and the test runner, documents the reproduction contract gap that slice 2 must flip, and defines the FIXTURE_MARKER, FIXTURE_SKILL_NAME, and CHILD_FLAG constants.
  • observed — Modified behavior in tests/orchestrator-inline-skill-execution.test.ts: Defines the fixture SKILL.md front matter and body with an ## Output Contract section whose only content is the marker line that must appear in results.
  • observed — Modified behavior in tests/orchestrator-inline-skill-execution.test.ts: Adds helpers extensionSourceUrl (URL-escapes a packaged extension path relative to this file) and buildShimSource (a shim that activates the gentle-ai and skill-registry extensions with network, review CLI, candidate views, and process env disabled).
  • observed — Modified behavior in tests/orchestrator-inline-skill-execution.test.ts: Adds the two slice-2 flip targets: assertParentPromptHasNoInlineSkillReadObligation asserts the prompt matches none of three parent-inline/SKILL.md binding patterns with a failure message containing the offending line; assertParentPromptOmitsSkillContractBody asserts the prompt does not include the supplied marker.

…d before_agent_start handler (Gentleman-Programming#348)

CodeRabbit review follow-up on Gentleman-Programming#1357: the repro previously reconstructed
the parent prompt via __testing.buildGentlePrompt and asserted against
that reconstruction. It now registers the real gentle-ai extension on a
minimal capture-pi (accepted tests/runtime-harness.mjs surface), fires
the registered before_agent_start handler with the project cwd, and
asserts the b/c/d gap checks against the handler-returned systemPrompt,
so the repro binds the prompt the primary session actually delivers.
Telemetry is deterministically skipped via the GENTLE_AI_TELEMETRY kill
switch; the fail-closed unknown RDD line stays pinned.

Addressed in cb4d4aa: the repro now registers the real gentle-ai extension on a minimal capture-pi (the accepted tests/runtime-harness.mjs surface), fires the registered before_agent_start handler with the project cwd, and runs the b/c/d gap checks against the handler-returned systemPrompt instead of the buildGentlePrompt reconstruction. Fidelity pins prove the handler path (probe base prefix + the fail-closed unknown RDD line). Telemetry is deterministically skipped via the GENTLE_AI_TELEMETRY kill switch.

…ill-contracts (chain superset: collapse diff to the fix slice after Gentleman-Programming#1357 merges)

# Conflicts:
#	tests/orchestrator-inline-skill-execution.test.ts
The Windows candidate view regression fails its first owner-preparation
git command with candidate-owner-preparation-failed (ETIMEDOUT) when a
cold windows-latest runner exceeds the 10s CANDIDATE_GIT_TIMEOUT_MS cap
(Gentleman-Programming#990, Gentleman-Programming#1009 family). Set GENTLE_PI_CANDIDATE_GIT_TIMEOUT_MS=60000 on
that step using the override the cap already provides (max 120s) rather
than retrying: a git timeout is a diagnosable candidate state, not a
transient error.
…appendSystemPrompt handler contract

Main's gentle-shell#1485 changed before_agent_start to compose through the
mutable systemPromptOptions.appendSystemPrompt section (pi-claude-bridge
drops handler-returned replacement prompts), which broke the probe's
handlerResult.systemPrompt capture after the main merge. The probe now
passes the structured options and reconstructs the delivered prompt as base
plus appended block; the gap assertions are unchanged and the repro still
passes on unmodified main.

Merged current main forward (199 commits, no conflicts) plus one adaptation: main's gentle-shell#1485 changed the before_agent_start contract to compose through systemPromptOptions.appendSystemPrompt (the handler returns undefined now), which broke the probe's handlerResult.systemPrompt capture. The probe now passes the structured options and reconstructs the delivered prompt as base plus appended block; all gap assertions are unchanged and the repro still passes on unmodified main (1/1 locally).

Ready for review; #1358 carries the fix slice on top.

Consolidated into #1358, which already contains every commit here (the repro test plus the fix that flips it). One PR, one review, and fewer total lines to read than the chain. Closing this slice.
