Yao Meta Skill

YAO stands for Yielding AI Outcomes — the goal is not to generate more prompt text, but to produce reusable AI assets and real operational outcomes.

yao-meta-skill is a lightweight but rigorous system for creating, evaluating, packaging, and governing reusable agent skills.

Quick Start · Examples · Evals · Failure Library · Method Doctrine

It turns rough workflows, transcripts, prompts, notes, and runbooks into reusable skill packages with:

• a clear trigger surface
• a lean SKILL.md
• optional references, scripts, and evals
• a front-loaded intent dialogue with an intent confidence gate, so the system keeps clarifying when the true job, outputs, exclusions, or standards are still fuzzy
• a silent-by-default GitHub benchmark scan plus reference synthesis that studies top public repositories and world-class pattern tracks, then surfaces only real conflicts or uncertainty to the user
• a generated visual HTML overview for each newly initialized skill
• a Review Studio 2.0 HTML gate page that combines intent, trigger, output eval, context, runtime, trust, atlas, adoption drift, reviewer waivers, reviewer annotations, release evidence, and per-warning fix actions
• a Skill OS 2.0 audit that maps each world-class requirement to current evidence, human-required gaps, and external-required gaps
• a Skill OS 2.0 blueprint coverage report that maps the upgrade plan’s core modules and recommended PRs to concrete artifacts, commands, and tests
• a world-class evidence plan that turns remaining provider, human, native-permission, and real-client telemetry gaps into executable evidence tasks
• a world-class evidence ledger that records which external and human evidence is accepted or still pending without treating planned work as proof
• a world-class evidence intake contract that validates external and human evidence packets for provenance, privacy, artifact refs, and anti-overclaim rules before ledger review
• a redacted world-class preflight report that checks local files, environment readiness, human/external prerequisites, and source blockers before operators collect evidence
• a world-class submission review queue that compares evidence packets, intake validation, source artifacts, and ledger state without accepting evidence
• a world-class operator runbook that gives reviewers the exact commands, artifacts, and collection checklist needed to close remaining evidence gaps
• a world-class claim guard that scans public claim surfaces and blocks premature completed/true claims while the evidence ledger still has pending external or human evidence
• a benchmark reproducibility manifest that checks methodology sections, required artifacts, failure disclosure, and reproduction commands
• an evidence consistency gate that compares generated reports against each other so benchmark, overview, interpretation, adoption, world-class ledger, coverage, and Review Studio facts do not drift silently
• Output Eval Lab evidence with assertion grading, execution/timing/token evidence, a blind A/B review pack, a separate answer key, and reviewer adjudication reports
• a runtime permission probe report that checks packaged target adapters for explicit permission metadata, native-enforcement flags, metadata fallback notes, and residual risks
• a Python compatibility gate that catches supported-runtime syntax hazards before they reach GitHub Actions or packaged distribution
• a side-by-side HTML review studio for first-pass human review
• an artifact design profile that defines visual direction, layout patterns, and quality gates for reports, tutorials, dashboards, screenshots, and review pages
• a prompt quality profile that abstracts need modeling, RTF mapping, complexity, and quality checks into reviewer-visible evidence instead of bloating SKILL.md
• a systems-thinking model that maps boundaries, feedback loops, drift risks, recurring failure patterns, and highest-leverage quality moves
• three high-value next iteration directions after the first package is created
• a lightweight feedback log that does not require a full promotion cycle
• a local-first metadata-only adoption and drift report that turns real usage signals into next iteration candidates, with optional yao.py CLI run capture, external client event emit hooks, hook recipes, and JSONL import that record command names and outcomes without arguments or raw content
• an explicit-source adaptive proposal loop that summarizes redacted repeated user preferences and generates approval-gated adaptation proposals without scanning private logs or writing source files
• a SkillOps opportunity scorer and decision policy that ranks redacted repeated signals, maps them to report-only, AGENTS update, existing-skill patch, or eval-addition actions, and keeps every durable write approval-gated
• a weekly SkillOps curator report that aggregates daily opportunities, Skill Atlas portfolio signals, release lock state, and world-class evidence gaps into a proposal-only maintenance queue
• a Browser/Chrome Native Messaging telemetry host that can receive length-prefixed metadata-only client events and generate a local launcher plus manifest without storing raw content
• a Skill Atlas drift layer that reads aggregate adoption reports and surfaces portfolio-level drift signals without packaging raw telemetry logs
• a baseline compare report for with-skill vs baseline review
• a conversation-style, archetype-aware quickstart that steers new packages toward scaffold, production, library, or governed fits
• Skill IR as the platform-neutral semantic contract, plus compiler reports and client-specific adapters
• Registry audit metadata with package version, owner, license, checksum, and compatibility matrix
• governance, promotion, and portability checks built into the default flow

Architecture

Hero view: turn messy operational input into a governed, reusable skill package through one compact flow.

flowchart LR
    A["Inputs<br/>workflow / prompt / transcript / docs / notes"] --> B["Route<br/>SKILL.md"]
    B --> C["Design<br/>method + gates"]
    C --> D["Run<br/>create / validate / eval / promote"]
    D --> E["Outputs<br/>skill package + reports + adapters"]

Read it in 10 seconds:

• Inputs: start from rough operational material.
• Route: define boundary and trigger in a lean SKILL.md.
• Design: choose the right archetype, gates, and resource split.
• Run: use the unified CLI to build, validate, optimize, and promote.
• Outputs: ship a reusable skill plus evidence, governance signals, and portability artifacts.

Weighted Quality Benchmark

This benchmark is a project-level engineering review, scored from 0-10 per dimension and weighted to 100. GitHub stars are intentionally excluded because they measure ecosystem heat, not meta-skill engineering quality.

Weighted score formula: sum(score / 10 * weight).

Best-Fit Scenarios

• Choose Yao Meta Skill when the target is a reusable team asset with explicit boundaries, trigger evaluation, governance, packaging, portability, and local execution checks.
• Choose Anthropic Skill Creator when the target is a conversation-first creation loop and the priority is human-guided iteration over repository-level governance.
• Choose OpenAI Skill Creator when the target is a compact reference for writing lean skill instructions and keeping context small.
• A practical hybrid pattern is still useful: draft conversationally, then use yao-meta-skill to harden the package, add evidence, and make it team-ready.

Quick Start

1. Describe the workflow, prompt set, or repeated task you want to turn into a skill.
2. Start with a short, human intent dialogue so the real job, outputs, exclusions, constraints, and standards are explicit.
3. Let quickstart clarify intent first, then run silent benchmark scan and reference synthesis; it only surfaces explicit questions when intent is still unclear or when there is a real design conflict.
4. Use the archetype-aware quickstart or the full authoring flow to generate or improve the package in scaffold, production, library, or governed mode.
5. Review the generated reports/skill-interpretation.html first for the bilingual interpretation report. It defaults to Simplified Chinese and provides an English switch in the top right. Then open reports/skill-overview.html for the audit scorecard and reports/review-studio.html to inspect release blockers, permission approvals, and evidence paths in one page before adding more structure.

Or use the unified authoring CLI:

Local Development Source

Development source: this repository is the source of truth for authoring and review.

Disabled mirror: ~/.agents/skills.disabled/yao-meta-skill is the local backup mirror for this source. Keeping the mirror outside ~/.agents/skills prevents Codex from showing a duplicate Yao Meta Skill while this repository is also visible in the active workspace.

Sync the current source into the disabled mirror:

make sync-local-install

The sync command first rebuilds the package and runs install preflight against dist/yao-meta-skill.zip. It refuses to sync when package extraction, adapter readability, or installer permission enforcement fails. After the preflight passes, it copies Git-tracked files plus new source files in code and guidance directories such as scripts/, tests/, references/, and docs/. It skips untracked business-skill folders and untracked private reports by default, so local experiments do not leak into the mirror.

Restore an active global Codex install only when you intentionally want this skill discoverable outside the development workspace:

make sync-active-install

That active install writes to ~/.agents/skills/yao-meta-skill and can make Codex show a second Yao Meta Skill entry while this repository is open as a skills workspace.

Generated Artifact Boundaries

Keep this repository focused on the meta-skill factory.

• Put reusable factory examples in examples/.
• Put reusable benchmark evidence, regression results, and release evidence in reports/.
• Keep private analysis reports, customer-specific outputs, and one-off generated business skills outside this repository unless they are intentionally promoted into an example or regression fixture.
• Place real generated skills as sibling skill directories under the local skill workspace, not as top-level folders inside yao-meta-skill.

5-Minute Workflow

1. Start from a raw workflow note.
2. Turn it into a skill package with SKILL.md, agents/interface.yaml, and only the folders the workflow actually needs.
3. Validate the trigger description with evals/trigger_cases.json.
4. Export compatibility artifacts for the clients you care about.
5. Compare the result against the examples in examples/.

Minimum commands:

python3 scripts/trigger_eval.py --description-file evals/improved_description.txt --cases evals/trigger_cases.json
python3 scripts/run_description_optimization_suite.py
python3 scripts/judge_blind_eval.py --description-file SKILL.md --cases evals/blind_holdout/trigger_cases.json --semantic-config evals/semantic_config.json
python3 scripts/context_sizer.py .
python3 scripts/resource_boundary_check.py .
python3 scripts/governance_check.py . --require-manifest
python3 scripts/compile_skill.py .
python3 scripts/cross_packager.py . --platform openai --platform claude --platform generic --platform vscode --expectations evals/packaging_expectations.json --zip
python3 scripts/probe_runtime_permissions.py . --package-dir dist
python3 tests/verify_packager_failures.py

Or run everything together:

make test

Unified authoring flow:

python3 scripts/yao.py init my-skill --description "Describe what the skill does."
python3 scripts/yao.py validate my-skill
python3 scripts/yao.py workspace-flow --target root --label first-pass
python3 scripts/yao.py review-viewer my-skill
python3 scripts/yao.py review --target root
python3 scripts/yao.py release-snapshot --target root --label release-candidate
python3 scripts/yao.py skill-ir . --output-json skill-ir/examples/yao-meta-skill.json

Results

The homepage panel below is generated from the current eval suite so the family-level outcome is visible without opening raw JSON.

• regression corpus: 66 prompts across 21 families
• aggregate result: 0 false positives, 0 false negatives, average precision 1.0, average recall 1.0
• suite status:

Full reports: reports/eval_suite.json and reports/family_summary.md

• packaging validation: openai, claude, generic, and vscode targets pass contract checks and carry IR provenance, semantic parity metadata, and target-native behavior contracts
• target compiler validation: openai, claude, generic, Agent Skills compatible, and VS Code / Copilot contracts are compiled from Skill IR with generated-file mappings, adapter modes, native surfaces, permission enforcement notes, and unsupported-feature notes
• runtime permission probes: openai, claude, generic, and vscode adapters expose explicit permission contracts; current targets report 0 native-enforcement adapters and 4 metadata fallbacks with residual risks visible to reviewers
• portability score: 100/100 with neutral activation, execution, trust, and degradation metadata preserved across all exported targets
• description optimization suite: root, team frontend review, and governed incident command pass blind and adversarial holdout gates; governed incident command still carries one visible holdout miss, and adversarial calibration plus family drift are now tracked separately
• judge-backed blind eval: root, team frontend review, and governed incident command now pass an independent rubric judge on blind holdout prompts
• packaging failure fixtures: invalid metadata, invalid YAML, and unsupported targets fail as expected
• failure library regressions: anti-pattern families pass automated checks
• governance and resource-boundary checks are part of the default test path
• root governance maturity score: 90/100; governed benchmark example: 95/100
• CJK-aware trigger matching is now covered by explicit Chinese build, packaging, eval, and near-neighbor cases

Current Strengths

The latest weighted review puts Yao at 91.5/100. The strongest dimensions are the ones that matter most when skills become long-lived team assets:

• Method depth 9.5: formal skill engineering doctrine, archetypes, gate selection, non-skill decisions, lifecycle governance, and resource boundaries.
• Toolchain completeness 9.5: authoring, validation, benchmark scan, description optimization, report generation, promotion checks, packaging, CI, and portability checks are wired into one operational flow.
• Eval and test rigor 9.5: trigger quality is checked with train/dev/holdout, blind holdout, adversarial holdout, judge-backed blind eval, route confusion, drift history, and promotion gates.
• Governance and lifecycle 9.5: important skills can carry owner, lifecycle state, review cadence, maturity score, trust boundaries, promotion decisions, and regression history.
• Local execution reliability 9.5: the repository is executable locally through make test, make ci-test, and the unified scripts/yao.py authoring CLI.
• Portability and distribution 9.0: neutral source metadata, client adapters, degradation rules, packaging contracts, and portability scoring preserve reusable semantics across target environments.
• Systems stability: generated skills now include a system model that turns boundary discipline, feedback loops, drift watch, and leverage-point analysis into reviewer-visible evidence.
• Context discipline 8.0: the entrypoint is still held under budget, but this is tracked as a live constraint because the system now carries more reports, examples, benchmark assets, and generated evidence.
• Onboarding and review experience 6.5: quickstart, HTML overview, side-by-side review viewer, and feedback logs have improved the first-run experience, but this remains the clearest UX improvement area.

The current direction is deliberate: keep the entrypoint light, make evaluation hard to fake, make governance visible, and continue reducing the friction of first-time creation and review.

Why Yao

• Lightweight: the entrypoint stays compact, context budgets are explicit, and extra structure is added only when it pays for itself.
• Rigorous: trigger quality is checked with family regressions, blind holdout, adversarial holdout, route confusion, judge-backed blind eval, and promotion gates.
• Governed: important skills are treated as maintainable assets with lifecycle state, maturity expectations, ownership, and review cadence.
• Portable: source metadata stays neutral while adapters, degradation rules, and packaging contracts preserve reusable semantics across environments.

What It Does

This project helps you create, refactor, evaluate, and package skills as durable capability bundles rather than one-off prompts.

The design logic is simple:

1. Capture the real recurring job behind the user’s request.
2. Set a clean skill boundary so one package does one coherent job.
3. Optimize the trigger description before over-writing the body.
4. Keep the main skill file small and move details into references or scripts.
5. Add quality gates only when they pay for themselves.
6. Export compatibility artifacts only for the clients you actually need.

Method Doctrine

The repository now treats method as a first-class asset instead of scattered guidance.

• Skill Engineering Method
• Intent Dialogue
• Reference Scan Strategy
• Pattern Extraction Doctrine
• Output Quality Risk
• Authoring Discipline
• Skill Archetypes
• Gate Selection
• Iteration Philosophy
• Non-Skill Decision Tree
• Regression Cause Taxonomy
• Human Review Template

Why It Exists

Most teams keep valuable operating knowledge scattered across chats, personal prompts, oral habits, and undocumented workflows. This project converts that hidden process knowledge into:

• discoverable skill packages
• repeatable execution flows
• lower-context instructions
• reusable team assets
• compatibility-ready distributions

Core Components

SKILL.md

The main skill entrypoint. It defines the trigger surface, operating modes, compact workflow, and output contract.

agents/interface.yaml

The neutral metadata source of truth. It stores display and compatibility metadata without locking the source tree to one vendor-specific path.

references/

Long-form material that should not bloat the main skill file. This includes design rules, evaluation guidance, compatibility strategy, and quality rubrics.

scripts/

Utility scripts that make the meta-skill operational:

• trigger_eval.py: evaluates trigger descriptions with semantic intent concepts, explicit exclusions, and near-neighbor prompts
• run_eval_suite.py: runs train/dev/holdout trigger suites, reports family-level regressions, and fails if aggregate regressions appear
• optimize_description.py: generates candidate descriptions, scores them on dev, visible holdout, blind holdout, and adversarial holdout suites, then reports calibration and family health
• judge_blind_eval.py: applies an independent rubric judge to blind-holdout prompts so blind acceptance is not backed only by the main threshold scorer
• run_description_optimization_suite.py: runs description optimization across the root skill and governed examples, then writes reusable reports and optional drift snapshots with calibration and family summaries
• promotion_checker.py: applies promotion policy to current description candidates, writes promotion decisions, builds candidate registries, and emits iteration bundles with review stubs
• create_iteration_snapshot.py: freezes the current promotion decision into a versioned release snapshot with review, route, and context evidence
• yao.py: unified authoring CLI that exposes init, validate, optimize-description, promote-check, python-compat, review, release-snapshot, workspace-flow, report, skill-report, skill-interpretation, skill-ir, compile-skill, output-exec, output-review, skill-os2-audit, skill-os2-coverage, world-class-evidence, world-class-ledger, world-class-intake, world-class-preflight, world-class-submission-kit, world-class-submission-review, world-class-runbook, world-class-claim-guard, benchmark-reproducibility, evidence-consistency, adapt-scan, adapt-propose, adapt-apply, daily-skillops, weekly-curator, telemetry-emit, telemetry-hooks, telemetry-import, package, registry-audit, package-verify, install-simulate, upgrade-check, review-waivers, and test as one entrypoint

evals/

Reusable trigger and packaging checks, including baseline and improved descriptions for comparison plus the root semantic configuration that drives description optimization.

This directory also contains route confusion fixtures and promotion policy rules for deciding when a route is promotable.

examples/

End-to-end examples showing raw workflow input, design summary, final generated skill shape, and targeted description-optimization packs where route wording is tuned against example-specific dev and holdout cases.

.github/workflows/test.yml

Continuous integration entrypoint that runs the full local regression suite on push and pull request.

Validation Notes

• Trigger evaluation now uses a local semantic-intent model with explicit positive concepts, exclusion concepts, and boundary-case reporting.
• The sample trigger report now covers a larger positive, negative, and near-neighbor set rather than a tiny demo set.
• Train/dev/holdout trigger suites now separate iterative tuning from final verification.
• Description optimization now uses dev for ranking, visible holdout for non-regression, blind holdout for acceptance, and adversarial holdout for harder route-collision checks without feeding the ranking loop.
• Judge-backed blind eval now adds a rubric-based second opinion for blind prompts, so blind acceptance is not decided by one scorer alone.
• Description drift history now records adversarial calibration gaps and family coverage, so routing changes can be judged on confidence and family stability rather than raw error counts alone.
• Route confusion is now tracked explicitly across the root meta-skill, frontend review skill, governed incident skill, and no_route cases, so route theft is visible instead of implicit.
• Promotion policy now requires visible holdout, blind holdout, adversarial holdout, and route confusion to stay clean before a description should be considered promotable.
• Promotion checking now emits explicit decisions, candidate lifecycle states, iteration bundles, and human-review stubs rather than leaving promotion as a prose-only step.
• Promotion decisions now distinguish “no candidate beat current” from “current still has residual route risk,” so iteration can be audited without forcing every issue into a false block.
• Packaging validation now uses explicit contracts and YAML parsing, but it is still a lightweight local validation layer rather than a full platform integration suite.
• evals/failure-cases.md captures known weak spots that should remain part of regression checks.
• failures/ captures reusable anti-pattern writeups and machine-runnable failure cases for routing, packaging, and authoring failures.
• tests/verify_packager_failures.py checks that invalid metadata, invalid YAML, and unsupported targets fail clearly.
• Governance metadata and resource-boundary rules now have runnable checks instead of staying as prose only.
• Governance checks now emit a maturity score so governed assets can be compared instead of only pass/fail checked.
• Description optimization drift history is now versioned separately from the main trigger regression history so routing improvements are visible over time.
• Iteration evidence now records why a candidate was kept, blocked, or promotable via a shared regression-cause taxonomy and bundle artifacts.
• Declared maturity tiers are checked against recommended minimum governance scores, so production, library, and governed assets can be compared without forcing every strong example into the same label.
• Context budgets are now tiered and explicit, so a governed skill can still choose a stricter production-sized initial-load budget.
• Resource-boundary checks now detect decorative directories and compute a local quality-density signal instead of only checking raw token counts.

Starter templates for simple and more advanced skill packages.

How To Use

1. Use the skill directly

Invoke yao-meta-skill when you want to:

• create a new skill
• improve an existing skill
• add evals to a skill
• convert a workflow into a reusable package
• prepare a skill for wider team adoption

2. Generate a new skill package

The typical flow is:

1. describe the workflow or capability
2. identify trigger phrases and outputs
3. choose scaffold, production, or library mode
4. generate the package
5. run the sizing and trigger checks if needed
6. export target-specific compatibility artifacts from the Skill IR contract

3. Export compatibility artifacts

Examples:

python3 scripts/export_skill_ir.py ./yao-meta-skill --output-json ./yao-meta-skill/reports/skill-ir.json
python3 scripts/compile_skill.py ./yao-meta-skill --target openai --target claude --target generic
python3 scripts/cross_packager.py ./yao-meta-skill --platform openai --platform claude --expectations evals/packaging_expectations.json --zip
python3 scripts/context_sizer.py ./yao-meta-skill
python3 scripts/resource_boundary_check.py ./yao-meta-skill
python3 scripts/governance_check.py ./yao-meta-skill --require-manifest
python3 scripts/trigger_eval.py --description-file evals/improved_description.txt --cases evals/trigger_cases.json --baseline-description-file evals/baseline_description.txt

Advantages

• Method-first, not prompt-first: skill creation is treated as a formal engineering workflow with archetypes, gate selection, and non-skill decisions.
• Trigger-aware by design: descriptions are optimized with route confusion, blind holdout, adversarial families, and promotion policy instead of one-shot intuition.
• Lightweight at the entrypoint: SKILL.md stays compact while references, scripts, and evals are only added when they pay for themselves.
• Toolchain-backed: initialization, validation, optimization, reporting, packaging, and testing are available through one unified CLI and CI path.
• Governed as an asset: important skills can carry ownership, lifecycle state, maturity expectations, and review cadence.
• Portable by default: source metadata stays neutral while adapters and degradation rules preserve compatibility across target environments.
• Evidence-rich: route scorecards, regression history, context budgets, portability scores, and promotion decisions are published as artifacts instead of hidden implementation detail.

Best Fit

This project is best for:

• agent builders
• internal tooling teams
• prompt engineers moving toward structured skills
• organizations building reusable skill libraries
