Our review

This meta-skill audits and validates the structural integrity and standardization of Codex and Claude skills using the skill-polisher tool.

Strengths

  • Deterministic audit with prebuilt scripts
  • Cross-flavor compatibility (Codex and Claude)
  • Clear reporting including TASTE score
  • Multiple scripts for different audit contexts (local, cross, single)

Limitations

  • Requires uv and its dependencies
  • Only works within .codex/skills and .claude/skills directories
  • Does not automatically fix issues (except adding @POLISHED seals)
When to use it

Use this skill when you need to ensure all skills in a project follow standard formatting and required frontmatter.

When not to use it

Do not use it if you intend to modify skill content or if your skills are not organized in .codex/skills or .claude/skills folders.

Security analysis

Safe
Quality score87/100

The skill only reads and audits skill files using local scripts; no destructive commands or data exfiltration. Bash tooling is used for script execution, but all actions are scoped to auditing and polishing, with no external URLs or malicious payloads.

No concerns found

Examples

Audit all Codex skills
Run skill-polisher on all skills in .codex/skills to check structural integrity.
Audit a single Codex skill
Audit the skill 'my-skill' in .codex/skills/my-skill for compliance.
Cross-flavor audit
Perform a cross-flavor audit of both .codex/skills and .claude/skills using the shared auditor.

Skill Polisher (Claude Code)

Audit Codex skills for structural integrity and standardization by using the existing Codex skill-polisher tooling.

Flavor Contract

  • Claude-flavored by default: validates Claude frontmatter/tooling rules.
  • Cross-flavored compatible via shared auditor (see Cross-Flavor Audit).

Target scope

  • Codex skills:
    • Single skill: .codex/skills/<skill-name>
    • Whole set: .codex/skills
  • Claude skills:
    • Single skill: .claude/skills/<skill-name>
    • Whole set: .claude/skills

Execution

Codex skills (preferred)

Use the Codex polisher for deterministic audits:

uv run .codex/skills/skill-polisher/scripts/polish_skill.py .codex/skills --all

For a single skill:

uv run .codex/skills/skill-polisher/scripts/polish_skill.py .codex/skills/<skill-name>

Claude skills (manual audit)

Claude skills do not share the Codex polisher; use a lightweight audit:

Get-ChildItem .claude/skills -Directory
Get-Content .claude/skills/<skill-name>/SKILL.md

Checks to confirm:

  • SKILL.md present
  • Frontmatter includes name and description
  • Any allowed-tools entries match Claude tool names (Read, Write, Glob, Grep, Bash as needed)

Cross-Flavor Audit (shared)

Use the shared auditor when you want consistent reporting:

uv run scripts/skill_audit.py --flavor codex --root .codex/skills
uv run scripts/skill_audit.py --flavor claude --root .claude/skills

Hook (Claude-side)

Run the Claude cross-compatible audit via the helper script:

.\scripts\run_claude_skill_polisher.ps1 -Root .claude/skills

Claude-Local Audit (Claude-centric outputs)

Write JSON outputs into claude/mailbox:

.\scripts\run_claude_local_audit.ps1 -Root .claude/skills

Hook (Claude-side cross-polish)

Run both Codex and Claude audits in one pass:

.\scripts\run_claude_cross_polish.ps1 -CodexRoot .codex/skills -ClaudeRoot .claude/skills

Bridge (Codex tooling)

Invoke Codex polisher from Claude:

.\scripts\run_codex_polisher.ps1 -Root .codex/skills

Reporting

Summarize:

  • TASTE + score
  • Issues (if any)
  • Files changed (if any)

Notes

  • This skill audits Codex and Claude skills; do not modify either unless explicitly requested.
  • If you need to add @POLISHED seals, do so after a clean run and record the timestamp.

Cross-Flavor Compatibility

  • Codex flavor: requires agents/openai.yaml and assets/ with SVG icons.
  • Claude flavor: requires SKILL.md with valid frontmatter (name, description), optional allowed-tools.
  • For shared audits use: python scripts/skill_audit.py --flavor codex --root .codex/skills and python scripts/skill_audit.py --flavor claude --root .claude/skills.
