Agent Skills Creator

Create and improve skills in the Agent Skills open format: full lifecycle from pattern selection through validation and README update.

• IS: creating new agent skills and auditing or rewriting existing ones: SKILL.md, references, rules folders, scripts, evaluations.
• IS NOT: AGENTS.md/CLAUDE.md instruction files (use agents-md) or general documentation quality (use ghostwriter).

Choose a Mode

• New skill → Creation Workflow below.
• Audit, improve, or rewrite an existing skill → references/improving-existing-skills.md, which scores eleven audit dimensions, runs an ordered rewrite, then reuses Steps 5-8 for validation and shipping.
• Simplify a skill or update a collection → same reference, plus references/capability-delta.md for retention decisions and the collection ledger.
• Skill never triggers, triggers on the wrong prompts, or its description is being trimmed in a crowded listing → the Routing Evals section of references/evaluation-and-iteration.md, then the description. Body edits do not fix routing.
• Skill stops after a first draft and hands back for review when nobody asked → "Say Where the Work Ends" in references/authoring-tips.md; the fix is the scope of done and the review checkpoints, not the steps.
