Skill Reviewer

A quality gate for Claude Code skills: audits your own or others' skills against official best practices and can even open an improvement PR.

What it does

  • Runs an automated review of a Claude Code skill against official best practices: frontmatter (name/description), third-person phrasing, presence of trigger conditions, SKILL.md size (under 500 lines), directory layout, hardcoded paths and secrets, script error handling, and subagent_type validity.
  • Offers three modes: self-review (before publishing), external review (evaluate someone else's repo and produce an improvement report), and auto-PR (fork, improve, submit).
  • Uses clear exit codes: 0 = clean, 1 = warnings only, 2 = review errors, 3 = the reviewer itself failed.
  • Enforces an additive-only contribution philosophy: never delete files, remove features, or switch the original language — plus respectful PR wording templates and required PR sections.

Who it's for

  • Skill authors who want a quality check before publishing to a marketplace or GitHub
  • Maintainers of multi-skill repositories
  • Contributors who want to send polite, well-justified PRs to open-source skills

Examples

  1. Pre-release check: "Review my pdf-helper skill" → flags a first-person description with no trigger conditions and proposes a rewritten line.
  2. External audit: give it a GitHub skill repo; it clones to /tmp, reads all docs, and produces a checklist-based improvement report.
  3. Automated contribution: forks the repo, creates a branch, applies additive-only improvements, and drafts a PR with Summary / What's NOT Changed / Rationale / Test Plan.

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the daymade-skill/skill-reviewer folder from the GitHub repo daymade/claude-code-skills into my ~/.claude/skills/skill-reviewer/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/daymade/claude-code-skills.git /tmp/claude-code-skills && mkdir -p ~/.claude/skills && cp -r /tmp/claude-code-skills/daymade-skill/skill-reviewer ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Install uv, which the review script needs: curl -LsSf https://astral.sh/uv/install.sh | sh
  2. Clone the repository: git clone https://github.com/daymade/claude-code-skills.git /tmp/claude-code-skills
  3. Create the skills folder if needed: mkdir -p ~/.claude/skills
  4. Copy this skill: cp -r /tmp/claude-code-skills/daymade-skill/skill-reviewer ~/.claude/skills/
  5. Also copy the sibling skill it relies on for deeper security scans: cp -r /tmp/claude-code-skills/daymade-skill/skill-creator ~/.claude/skills/
  6. Restart Claude Code and ask: "Use skill-reviewer to review ~/.claude/skills/<skill-name>"
  7. Read the outcome by exit code: 0 clean, 1 warnings, 2 errors, 3 the reviewer could not run (check your uv install).
