Skill Creator

--- name: skill-creator description: ALWAYS use this when creating, rewriting, packaging, evaluating, or tightening any skill, trigger description, skill metadata, or bundled resource in this repository.

Skill Creator

Selective Reading Rule

Start with:

• references/usage-routing.md
• references/quality-checklist.md

Then load only the inherited docs, scripts, assets, or examples that match the user's actual task.

Purpose

Build skills that are easy to trigger, easy to follow, and honest about what they require.

The goal is not to produce more files. The goal is to produce a better operating guide for future agents.

Selective Reading Rule

Start with:

• references/senior-master-standard.md
• references/trigger-writing.md when rewriting descriptions or trying to make a skill trigger more reliably
• references/bundle-evaluation.md when changing many skills at once or preparing a bundle for review

Start Here

For any new or updated skill, define:

• the exact situations that should trigger it
• the workflow or judgment it should teach
• the resources it needs beyond the core instructions
• how another agent would verify the skill is useful

Workflow

1. Capture intent.
   • what job should the skill help an agent do?
2. Define the trigger language.
   • write the frontmatter description around when to use the skill, not a long process summary
3. Draft the core workflow.
   • keep SKILL.md focused on decisions, sequence, and quality bar
4. Split only when needed.
   • move heavy detail into references/, deterministic helpers into scripts/, reusable outputs into assets/
5. Add UI metadata.
   • create or refresh agents/openai.yaml for important skills
6. Validate.
   • confirm the wording is clear, the references exist, and the workflow matches the actual repo

Writing Rules

• Keep the description focused on triggering conditions.
• Keep the body focused on what the agent should actually do.
• Prefer concise structure over narrative explanation.
• Remove stale ecosystem references that do not apply to this repo.
• Do not promise scripts, tools, or flows that are missing.

Progressive Disclosure

Use this split:

• SKILL.md for the primary operating guide
• references/ for optional depth
• scripts/ for repeatable utilities
• assets/ for templates or output resources

If a detail does not need to load on every trigger, move it out of the core file.

Validation Checklist

• does the description make the skill discoverable?
• does the body tell the agent what to do next?
• are all referenced files real and relevant?
• is the skill aligned with Codex tools and this repo's structure?
• would another agent know when not to use it?
• did you run scripts/quick_validate.py on the touched skill?
• for bundle-wide work, did you run scripts/validate_skill_bundle.py and inspect the report?

Updating Existing Skills

When improving an inherited skill:

• remove stale brand or platform references
• rewrite around the actual environment and tools available now
• merge overlapping ideas instead of duplicating another skill
• keep the result stylistically consistent with the rest of the bundle

Useful Local Assets

Use the existing local helpers only when they materially help the task:

• scripts/quick_validate.py
• scripts/validate_skill_bundle.py
• scripts/package_skill.py
• eval-viewer/
• references/schemas.md
• references/trigger-writing.md
• references/bundle-evaluation.md

Do not force an evaluation loop when a smaller validation pass is enough.
