Skill Polisher

VerifiedSafe

Validates and standardizes Codex and Claude skills by checking structural integrity (SKILL.md existence, valid frontmatter) using existing tools like polish_skill.py or skill_audit.py. Helps maintain consistency across skill repositories during audits or standardization sweeps.

Our review

Audits and polishes Codex and Claude skills to ensure structural integrity and standardization using dedicated tooling.

Strengths

  • Automates validation of skill structure
  • Supports cross-flavor audits (Codex and Claude)
  • Provides deterministic polishing scripts
  • Generates reports with scores

Limitations

  • Requires existing Codex polisher setup
  • Only works with specific directory structures
  • Does not modify skills unless explicitly requested
When to use it

When you need to ensure all Codex/Claude skills follow structural standards before deployment or sharing.

When not to use it

When you want to create or modify skills, as this is an auditing tool.

Security analysis

Safe
Quality score92/100

The skill executes only local, pre-existing scripts (uv run, PowerShell) for auditing purposes. No network downloads, arbitrary code execution, or destructive commands are instructed. Bash is allowed-tool but commands are deterministic and safe.

No concerns found

Examples

Run Codex polisher on all skills
Run the Codex skill-polisher on all skills in .codex/skills and report any issues.
Audit Claude skills for frontmatter
Check all Claude skills in .claude/skills for valid SKILL.md frontmatter (name and description).
Cross-flavor audit
Perform a cross-flavor audit on 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.
