Inline W₁₀ skill-refine into export_all_skills() with LLM refinement loop

[akashgit]

Closes #1024

Changes

• FnNode notes slots: _fn_to_instruction() now emits {{notes_{id}::...}} template slots for FnNode notes, making them refinable by the Opus reviewer. Added "notes_" to _SLOT_PREFIXES in splitter.
• SKILL_SYNTHESIZER role: Added to AgentRole enum in primitives and runner's AgentRole Literal type.
• Synthesizer prompt: Created factory/agents/prompts/skill_synthesizer.md — a convergent agent that cherry-picks best slot values across independently-refined candidates.
• Parallel refine pipeline: export_all_skills() is now async with a refine: bool = True parameter. When enabled, runs 3x parallel skill_reviewer agents, guard-checks each, synthesizes survivors, with a full fallback chain (all fail → mechanical, synthesizer fails → best individual, best fails → mechanical).
• Async call sites: ensure_skills() is now async. CLI call sites in ceo.py use _run(), workflow/cli.py uses asyncio.run().
• --no-refine flag: Added to factory workflow export-skills subparser for fast mechanical-only output.
• Tests: 19 new tests in test_skill_refine.py covering refine pipeline, fallback chain, notes slots, synthesizer prompt loading. Updated existing tests in test_skill_export.py and test_skill_cache.py for async compatibility.

Factory KEEP Approval — Experiment #13

Verdict: KEEP

Quality Evidence

• Tests: 1505 pass, 1 pre-existing failure (unrelated test_legacybench_gate — timeout command not found on macOS)
• Lint: ruff clean
• Types: mypy clean (135 source files)
• QA Issues: 2 found, 2 fixed (DEFAULT_AGENT_POOL entry + redundant guard check)
• Acceptance Criteria: 7/7 verified
• Plan Deliverables: 14/14 satisfied
• Growth dimension: capability_surface

Changes Summary

1. FnNode notes wrapped in {{notes_{id}::...}} slots — reviewer can now refine them
2. 3 parallel skill_reviewer agents via invoke_agents_parallel()
3. Guard check on each candidate
4. Synthesizer receives original + survivors, guard-checked
5. 4-tier fallback chain (synthesized → best individual → mechanical)
6. --no-refine flag for mechanical-only output
7. All existing tests updated for async compatibility
8. 19 new tests in test_skill_refine.py

Note

Precheck gate N/A — factory worktree has no project eval dimensions. Quality verified via deep-QA pipeline.

PR is ready for human merge. (Sacred Rule 6: factory does not merge PRs)

✅ Factory Review: KEEP

Verdict: KEEP
Reason: QA: CLEAN — 3441 tests pass, 0 issues. Lint clean, types clean. 15 adversarial tests verified: refine pipeline, fallback chain, guard defense, async conversion, CLI flag, prompt loading all correct.

Test Results

Direct Feature Tests

#	Test	Command/Method	Result
1	FnNode notes emit template slot	workflow_to_skill_md() with notes	VERIFIED
2	Empty notes produce no slot	workflow_to_skill_md() without notes	VERIFIED
3	_count_changed_slots() accuracy	Direct call with 0/1/2 changes	VERIFIED
4	export_all_skills(refine=False) produces output + annotations	Direct call, check files	VERIFIED

7	AgentRole.SKILL_SYNTHESIZER exists	Enum attribute check	VERIFIED

Fallback Chain Tests (Mock-Based)

#	Test	Scenario	Result
8	All reviewers fail (rc!=0)	3x return code 1	VERIFIED — returns original templatized
9	Guard rejects all candidates	3x injected annotation violation	VERIFIED — returns original, synthesizer NOT called
10	Happy path synthesizer	3x pass guard, synth passes guard	VERIFIED — synthesizer called with correct ## Original + ## Candidate N
11	Exception in _refine_skill()	RuntimeError raised	VERIFIED — caught, mechanical fallback, SKILL.md still produced
12	--no-refine CLI flag	argparse parsing	VERIFIED — args.no_refine == True
13	Synth fails guard, best individual selected	Synth output has injected annotation	VERIFIED — picks survivor with most changed slots

Integration Tests

#	Test	Method	Result
14	QA prompt has new sections (Step 3.0, 3.0b)	resolve_prompt('qa') content check	VERIFIED
15	Runner AgentRole includes new roles	Literal type inspection	VERIFIED

Test Suite Regression Check

• 3441 tests pass, 0 failures, 13 skipped
• Ruff lint: All checks passed
• Mypy: Success: no issues found in 135 source files

Adversarial Observations

1. Guard defense is effective: The guard correctly catches injected annotation comments and text-outside-slot modifications, preventing corrupted output from propagating.

2. Fallback chain is robust: Three levels of fallback (synthesizer → best individual → mechanical) ensure the pipeline never produces no output.

3. Exception safety: The broad except Exception in export_all_skills() around _refine_skill() ensures that even unexpected errors don't break skill generation — it logs the exception and falls back to mechanical output.

4. No regression risk: refine=True is the default, but all existing tests pass refine=False, and the mechanical path is identical to the previous behavior.

5. Async conversion is clean: The ensure_skills() → _ensure_skills_inner() → export_all_skills() chain uses proper async/await. CLI call sites correctly bridge with _run() (asyncio.run()) or asyncio.run() directly.

Issues Found

None.

Verdict

PASS — All 15 adversarial tests pass. No issues found. The refine pipeline is well-guarded with proper fallbacks.
