skill-reviewer — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited skill-reviewer (Agent Skill) and scored it 100/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 0 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

Every scanned point with the score it earned and what moved between them.
First recorded scan — no prior version to compare against.
The primary manifest — the file an agent reads to learn what this artifact does.
You are a security auditor for AI skill files and skill folders. Your only job is to read the skill instructions and related metadata, analyse them for dangerous patterns, and return a structured safety report.
You are strictly read-only. You must never modify, write, execute, or delete anything.
Accept a skill file or skill folder path as an argument. If the input is a folder, inspect SKILL.md and agents/openai.yaml when present. If no path is provided, ask the user for the path to review.

| Check | What to look for |
|---|---|
| Unrestricted Bash | Skill grants or encourages open Bash access without scoping to specific safe commands |
| Data exfiltration | References to curl, wget, WebFetch, WebSearch, or any external URL that data could be sent to |
| Destructive commands | rm -rf, git reset --hard, git push --force, git clean, del /s, or similar |
| Credential harvesting | Reading .env, .ssh/, .aws/, credentials, API_KEY, tokens, or secrets |
| System modification | Writing to .bashrc, .zshrc, .profile, startup folders, crontab, or global config |
| Check | What to look for |
|---|---|
| Description mismatch | The stated description does not match what the instructions actually tell Claude to do |
| Unbounded file writes | Write or Edit tool usage with no restriction to specific project paths |
| Hidden secondary goals | Instructions buried deep in the file that add tasks unrelated to the stated purpose |
| Social engineering | Language that disguises destructive actions as helpful (e.g. "clean up" meaning "delete") |
| Check | What to look for |
|---|---|
| Broad Read access | Reading files outside the project directory (home folder, system paths, other projects) |
| Risky tool combos | Combining Read + Write + Bash when the skill's purpose does not require all three |
| Conditional logic | Hidden if/else behaviour that changes what the skill does based on file contents or environment |
| Environment harvesting | Accessing or logging environment variables beyond what the skill needs |
