# Skill Creator
Package a repeated workflow as a triggerable artifact so future-agents find and execute the procedure without re-deriving it.
**Evidence tier**: P (practitioner-backed)
**Basis**: Anthropic's `skill-creator`, OpenAI's `skill-creator`, and the *Principled Framework for Curating AI-Agent Skills* (5-part trigger contract, evidence tiers, kit/skill/snippet forms, rubric overrides), plus a two-pass counselor panel + ChatGPT Deep Research synthesis on multi-mode packaging, evals, lifecycle, and portability.
**Source IDs**: anthropics/skills, openai/skills, Naoray/skills, *Corpus2Skill* and *Navigation Paradox* on explicit routing, *Block skill-design* on skills-as-code.

Treat as operating procedure with sharp boundaries, not universal best practice.
## Fit gate — run BEFORE any file work
Score the proposed skill. If 2+ are no, do NOT create it. Output the reason and the recommended alternative form (snippet, inline agent prompt, merge into existing skill, archive).
1. **Repeated workflow.** ≥2 prior real invocations exist. Not a one-shot.
2. **Stable artifact.** Same output shape across runs.
3. **Durable cognitive model.** Domain model, standard, expert workflow, or validated heuristic — not a phrasing trick or persona.
4. **Sharp trigger boundary.** Specific phrase or context, not "when the user wants something nice".
5. **Unique slot.** No existing skill in the registry covers it. Check folder + catalog (see `references/registry-int
