Formax skill capture (create skills from our workflow)

What this is

This skill is a Formax-specific wrapper around skill authoring: it helps us reliably convert “we just figured out how to do X” into a repo-local skill under .codex/skills/<skill-name>/.

It complements the built-in skill-creator (system skill) by adding Formax conventions:

• repo-local skills (checked into git)
• “where to change what” file map
• invariants (UI parity, model injection orthogonality, etc.)
• minimum regression tests to lock behavior

When to use

Trigger this when the user says:

• “把这个流程沉淀成 skill”
• “以后别再忘了怎么改 /xxx”
• “给我一个复用的修改清单/固定套路”

Minimal questions to ask (do not proceed until answered)

1. Skill name (kebab-case), e.g. formax-slash-command-workflow
2. 1–2 sentence description: when should Codex use it?
3. Scope: which subsystem? (pick one)
   • slash commands / overlays
   • tools (spec/handler/presenter)
   • hooks
   • permissions/policy
   • stability/input routing
4. Any explicit “don’t change” constraints? (UI copy/spacing/colors, contracts, etc.)

Output requirements

The resulting skill must include:

• a short “Goal” section
• “Where to change what” (file list)
• “Patterns” (2–4 common patterns)
• “Tests to update” (minimum regression set)
• “Guardrails” (what must not regress)

Avoid long prose; prefer checklists.

Create a new skill (scaffold)

Use the scaffold script:

bash .codex/skills/formax-skill-capture/scripts/new-skill.sh <skill-name> "<description>"

Then fill SKILL.md body with the content above.

Refactor policy for skills

When a skill is created from a workflow we already shipped:

• Do not broaden scope (no extra features)
• Do not rewrite UI (unless explicitly requested)
• Write/extend tests first if behavior has regressed before
