Our review

This meta-skill audits and polishes Codex and Claude skills using dedicated scripts, ensuring structural integrity and standardization.

Strengths

  • Automated validation of SKILL.md files and frontmatter structure
  • Supports single-skill or full-set audits
  • Cross-flavor compatibility between Codex and Claude formats
  • Detailed reporting with TASTE score, issues, and changed files

Limitations

  • Requires the polisher scripts to be present in the repository
  • Only works for skills organized under .codex/skills or .claude/skills directories
  • Claude audits are manual without the automated polisher
When to use it

Use this skill to audit and standardize your Codex or Claude skill set before review or deployment.

When not to use it

Avoid using it for non-skill tasks or when the polishing scripts are not set up.

Security analysis

Caution
Quality score85/100

The skill runs external scripts via 'uv run' and PowerShell, which could perform file modifications or execute code. While intended for auditing, these scripts' integrity must be ensured. No overtly malicious instructions, but caution advised.

Findings
  • Runs Python and PowerShell scripts that could potentially modify files or execute arbitrary code.
  • Uses Bash for running commands, which could be risky if the environment is not trusted.

Examples

Audit all Codex skills
Run the skill polisher on all skills under .codex/skills and report any issues.
Single skill audit
Audit the skill named 'my-skill' under .codex/skills using the polisher.
Cross-flavor audit
Perform a cross-flavor audit on both .codex/skills and .claude/skills using the shared auditor script.

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.
