Closes #348

Consolidates #1357 (the repro test slice, now closed): this branch already contained every #1357 commit, so one PR now carries the repro and the fix.

PR Type

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

Label request: type:bug (fork PR cannot self-label)

Summary

  • One clause in the always-on core Skill Registry Protocol extends the exact-file read duty to the parent's own inline path at the composition boundary (+49 B): "...or report unavailable paths; the parent's own inline path owes the same read."
  • New lazy ### Parent inline execution section carries the detail: in-session read, Output Contract markers in the reply, name-only attribution (Skill applied (inline): <name>), and the unreadable-path fallback. No skill_resolution tokens added; that contract stays delegation-only.
  • Canonical always-on budget pin re-measured to 7131 B at the controlled worst-case root: current main's SDD/openspec surface removal shrank the always-on core, and this branch's parent-inline clause (+49 B) lands on that smaller base (prior pin 8320 pre-dated that drift).
  • Two test layers: a contract test with per-clause negative controls and forbidden-token injections, and the runtime flip of test(orchestrator): reproduce the parent-inline skill contract gap (#348) #1357's repro proving the obligation IS delivered in the composed parent prompt while the contract body stays excluded.

size:exception

442 changed lines against main (438+/4-), requesting size:exception. Rationale:

Refresh and review provenance (2026-09-25)

  • Branch refreshed onto current main (merge 25663003, single assets/orchestrator.md conflict resolved: parent-inline clause kept, main's SDD-removal wording adopted), then absorbed refreshed test(orchestrator): reproduce the parent-inline skill contract gap (#348) #1357's head so this branch is a true superset (98f03c90).
  • Focused verification on the refreshed head: 38/38 pass (flipped runtime test 1/1, contract layer 3/3, budget 34/34 at the 7131 pin).
  • Native review approved for this exact candidate: lineage review-981fb1a6f24ef2d7 (high tier, lenses risk/resilience/readability/reliability, 4/4 reviewers), closure approved and acknowledgement burned. Nine advisory findings, all informational and non-blocking (test naming, budget-pin comment wording, unused fixture fields); recorded as follow-up work, not corrections to this candidate.

Changes Table

File Change
assets/orchestrator.md Skill Registry Protocol sentence extended with the parent-inline read duty (+49 B)
assets/orchestrator-skills.md New ### Parent inline execution lazy section (read discipline, contract markers, name-only attribution, unreadable-path fallback)
tests/orchestrator-budget.test.ts BUDGET_BYTES 8192 → 8320 with rationale comment; one test-name string updated
tests/orchestrator-inline-skill-execution.test.ts Flip of #1357's repro: asserts composition-boundary delivery of the obligation (guarded helpers inverted, exact-wording anchors)
tests/orchestrator-skills-inline-contract.test.ts New contract layer: happy path + per-clause negative controls + forbidden-token injections

Test Plan

  • orchestrator-inline-skill-execution 1/1 (offline runtime, delivery proof)
  • orchestrator-skills-inline-contract 3/3 (contract + negative controls)
  • orchestrator-budget 38/38 (both budget variants + namedPointers green; byte counts 8129/8234 of 8320)
  • skill-registry 17/17, orchestrator-rdd-ownership 7/7 (untouched, third budget site still fits)
  • check:provider-contract green
  • Full-suite attribution: inprocess-reviewer cancelled cluster (26) reproduces on clean main without this change; pre-existing, not a regression

Contributor Checklist

  • Linked an approved issue (Closes #348, status:approved)
  • Exactly one type:* label — requested above (fork PR cannot self-label)
  • No shell scripts modified (shellcheck n/a)
  • Skills load correctly in target agent (the runtime test boots a real offline session)
  • Docs updated if behavior changed (docs/readme-reference.md stays accurate: no new skill_resolution tokens)
  • Conventional commit format
  • No Co-Authored-By trailers

Summary by CodeRabbit

  • Documentation
    • Clarified how parent workflows apply and attribute skills inline, and updated the skill registry’s fallback reference.
  • Tests
    • Added coverage for inline skill guidance and updated the measured prompt budget.
  • Chores
    • Extended the Windows candidate-view regression test timeout.

…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.
Design note: issues/348#issuecomment-5784664642
…ead (Gentleman-Programming#348)

One clause in the always-on core Skill Registry Protocol extends the
exact-file read duty to the parent's own inline path at the composition
boundary (+49 B). The new lazy '### Parent inline execution' section in
orchestrator-skills.md carries the detail: in-session read, Output
Contract markers in the reply, name-only attribution line
(Skill applied (inline): <name>), and the unreadable-path fallback.

Budget: canonical always-on budget steps 8192 -> 8320 (next 256-B step).
The controlled-long assets root previously held 7 B headroom (frozen,
see odd/tasks/sdd-trigger-boundary.md), so the duty clause required the
step; margins are now 191 B (short root) and 86 B (long root).

Tests: a contract layer with per-clause negative controls and
forbidden-token injections binds the lazy section; the offline runtime
harness flips to prove composition-boundary delivery (fixture skill
indexed, obligation present in the composed prompt, contract body still
excluded, boot clean, fidelity pin intact).

Full-suite note: tests/inprocess-reviewer.test.ts has a pre-existing
cancelled cluster (26 cancelledByParent) that reproduces on clean main
without this change; unrelated. All suites covering the touched surfaces
pass.

Design note: issues/348#issuecomment-5784664642 (addendum follows).

📝 Walkthrough

Walkthrough

The orchestrator skill guidance now defines parent inline execution requirements. New tests check the guidance and composed prompt. The canonical prompt budget is updated, and the Windows candidate view regression test receives a Git timeout setting.

Changes

Parent inline skill execution

Layer / File(s) Summary
Inline skill requirements
assets/orchestrator-skills.md, assets/orchestrator.md
The guidance specifies reading the indexed skill, following its output contract, and adding skill-name attribution. If the skill path is unreadable, it specifies proceeding without the skill and stating that. The registry protocol changes its fallback label.
Contract and prompt tests
tests/orchestrator-skills-inline-contract.test.ts, tests/orchestrator-inline-skill-execution.test.ts, tests/orchestrator-budget.test.ts
Tests check required contract clauses, disallowed wording, and the composed prompt. The canonical prompt budget changes to 8,457 bytes; the separate core cap remains 8,400 bytes.

Windows regression test timeout

Layer / File(s) Summary
Test timeout setting
.github/workflows/ci.yml
The Windows candidate view regression test step sets GENTLE_PI_CANDIDATE_GIT_TIMEOUT_MS to 60000.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Change: Bug fix


Merge Risk: 🔵 Low · up to b8f39

The inline probe runs in Ubuntu CI, but a direct Windows test run can fail because its child environment may hide Git. This is a bounded developer-workflow issue, so the PR is mergeable with that limitation understood.

…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.

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.

Both slices for #348 are green and mergeable (repro test in #1357 + the contract fix here). Ready for a review window whenever suits you — happy to adjust anything.

…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.

Picked up the refreshed #1357 base (main forward, 199 commits) into this branch. Clean merge: the probe rewrite here does not depend on the handler-return shape, so gentle-shell#1485's appendSystemPrompt contract needs no change in this slice. All three suites green locally post-merge (38/38): inline-skill-execution, skills-inline-contract, orchestrator-budget.

Still draft pending a review window for the pair.

Add an execution-level inline skill assertion.

The test refreshes the registry and renders the parent prompt, but it never starts a model turn or observes a read tool call. A regression where the parent skips the indexed SKILL.md read and omits the fixture marker would still satisfy the changed tests.

Add an offline provider-backed turn that asserts the parent reads the indexed path, includes FIXTURE348-CONTRACT-MARK in the result, and emits Skill applied (inline): fixture-contract-probe. The existing registerProvider/streamSimple test seam in tests/orchestrator-consultation-sdk.test.ts provides a suitable pattern.

Hard-coded POSIX PATH makes the child env non-portable.

${dirname(process.execPath)}:/usr/bin:/bin uses : as the separator and Unix directories. On Windows, the separator is ;. The PR adds a Windows CI timeout, so Windows CI is in use. This test then spawns a child with a broken PATH. The child's own process.execPath is absolute, so Node starts. Any tool that the extension spawns from PATH (for example git) can be missing on Windows.
Build the value with path.delimiter. Add the system directories for the current platform.

…ithin Gentleman-Programming#1731's 8,400 B default-render guard

Merge-forward of origin/main (552 commits) exposed a real budget bust: the
branch's Gentleman-Programming#348 skill-registry clause on top of main's Gentleman-Programming#1731-narrowed core
pushed the default-root parent prompt to 8,413 B, over the Gentleman-Programming#1731 T10
user-decision 8,400 B guard in tests/orchestrator-rdd-ownership.test.ts.

Compress the clause to main's compact shape plus only the guarded
parent-inline duty sentence (-53 B): the default-root render measures
8,360 B, so the 8,400 guard passes untouched; the fallback-semantics
enumeration tokens stay out of the lazy section
(orchestrator-skills-inline-contract guard). The canonical worst-case
budget re-measures at 8,448 B at the controlled 128-char assets root and
is re-pinned with provenance; the `paths-injected` token the
skill-registry test pins stays in the core.
…backed inline turn

Resolve both CodeRabbit actionables on Gentleman-Programming#1358 (review 2026-10-09T09:43Z):

- Child PATH now joins the Node executable directory and the current
  platform's system directories (win32: SystemRoot\System32) with
  node:path's delimiter instead of a hardcoded ':'-separated Unix PATH.
- Add the execution half of the Gentleman-Programming#348 contract through the existing offline
  provider seam (modelRuntime.registerProvider + streamSimple with
  createAssistantMessageEventStream, as in bridge-wake-lifecycle): turn 1
  issues the read tool call on the exact registry-indexed SKILL.md path,
  the tool result carries the contract body, turn 2 applies the marker and
  closes with the 'Skill applied (inline): fixture-contract-probe'
  attribution line. The turn provably runs under the composed prompt that
  carries the read duty. The prompt-only guards
  (assertParentPromptCarriesInlineSkillReadObligation,
  assertParentPromptOmitsSkillContractBody) are unchanged.

Evidence: focused run green; negative probe (scripted model that skips the
read) fails the test, proving the new assertions bind.

Make the second provider request depend on the read result.

The second scripted response emits FIXTURE_MARKER unconditionally. A missing toolResult in providerRequests[1].messages can therefore go undetected. Assert that the second request contains the matching tool result and marker, then derive the scripted marker from that result before returning the final response.

Assert the attribution line’s position and uniqueness.

includes allows the attribution in the middle of the reply and allows duplicate attribution lines. Check that the final line is the attribution and that it occurs exactly once.

…an-Programming#348 turn script

The scripted provider's done event narrows reason to the no-error literal
union; share one stopReason const between the AssistantMessage field and
the event so typecheck records no new diagnostic (TS2322 at the done push).

The CR fixes are up (head b8f399642): both actionables from the 09:43 review are addressed, plus the merged budget re-pin (8,448 worst case; default-root render 8,360 stays under the 8,400 guard).

One check needs maintainer eyes: installer (windows-latest) fails deterministically 2/2 on this PR's last two heads, always as a file-level ✖ tests\installer-windows-bootstrap.test.ts (~5.9s) with zero test output and no stack (silent child exit). Triage so far:

Could a maintainer rerun installer (windows-latest) on run 37944780568? If it stays red I'll bisect the 6-file delta against the job from my side.

Update on the windows installer check: resolved. I refreshed the branch against main (head e1c61e99) and installer (windows-latest) is green now (run 37965076428), so no rerun is needed anymore.

For context, the failure was not content from this PR: the same job went red on main itself (c0672bb, 16:05 UTC) and green again 16 minutes later, and the installer hardening (#1978 PATHEXT, #1989 standalone pnpm) landed in that window. The refresh picked all of it up.
