- Evaluate a local Codex skill in engineer-friendly terms. Use when the user says "evaluate this skill", "give me an analysis of the game dev skill", "audit this skill", "why did this score that way", "what should I fix first", or asks for a skill-specific report before benchmarking it.
Evaluate Skill
Use this skill when the target is a local skill directory or SKILL.md file.
Workflow
- Treat "Evaluate this skill." as the default entrypoint.
- If the user names a skill instead of giving a path, resolve it locally first, preferring
~/.codex/skills/<skill-name>and then repo-localskills/<skill-name>. - If the user says the request in natural language first, use
plugin-eval start <skill-path> --request "<user request>" --format markdownto show the routed path clearly. - Run
plugin-eval analyze <skill-path> --format markdown. - Review
At a Glance,Why It Matters,Fix First, andRecommended Next Stepbefore drilling into details. - Explain which findings are structural, which are budget-related, and which are code-related.
- If the user asks for an "analysis" of the skill, do not stop at the report. Also run
plugin-eval init-benchmark <skill-path>and show the setup questions for refining the starter scenarios in.plugin-eval/benchmark.json. - If the user wants real usage numbers, switch to "Measure the real token usage of this skill." and run the benchmark flow.
- After observed usage is available, use
plugin-eval measurement-plan <skill-path> --observed-usage <usage.jsonl> --format markdownto recommend what to instrument or improve next. - If the user wants a rewrite plan, route to
../improve-skill/SKILL.md.
Skill-Specific Priorities
- frontmatter validity

- broken relative links
- oversized
