Yao Meta Skill

Router Rules

• Route by frontmatter description using the lightest mode.
• Keep SKILL.md lean: guidance in references/, logic in scripts/, evidence in reports/.

Modes

• Scaffold: exploratory; Production: team; Library: shared; Governed: release-critical.
• Rules: Method, Modes, Boundaries.

Compact Workflow

1. Require repeated use + reusable output contract; skip one-offs.
2. Lock target path + identity before writes; self-edits require --self.
3. Capture job, output, exclusions, constraints, standards, mode.
4. Scan 3-5 useful external/user/local references.
5. Write description early; route edits need trigger_eval.py; release gates follow risk.
6. Add deeper profiles only when earned.

Playbooks: Target Safety, Intent, Skill IR, Output Eval, Review Studio.

Updates

Activation: scripts/yao.py check-update --notice --self; show notice_text if requested; continue. “更新”: scripts/yao.py self-update --self --yes.

Skill OS 2.0 Gates

For production/library/governed releases, run Skill IR, compiler, trigger/output eval, Atlas, conformance, trust, package/install, upgrade, drift, waiver, Review Studio.

Governed Package Boundary

Governed/file-backed packages: label input_files a file-backed fixture; include owner, review cadence, output contract, rollback boundary; require trust report and reports/output_quality_scorecard.md; mark unavailable telemetry/approvals/metrics/benchmarks as missing evidence; never fabricate evidence.

Preserve labels literally when they apply: file-backed fixture, input_files, output contract, rollback boundary, trust report, reports/output_quality_scorecard.md, missing evidence.

First-Turn Style

• Infer non-core gaps; ask one core-fork question per round, max two, then use recorded preferred inference.
• In Chinese, sound soft and companion-like; use Intent Dialogue.

Output Contract

Builds: SKILL.md, aligned interface, justified assets, boundary/gate summary. Audits: findings + fixes; edit only when asked. No-skill: no files.
