Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00161 | $0.01946 |
| Opus 5.5 | $0.00064 | $0.00778 |
| Sonnet 5.5 | $0.00032 | $0.00389 |
| Haiku 4.5 | $0.00016 | $0.00195 |
Grade A, and why
skill-security-auditor scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 172 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Security Auditor
Scan and audit AI agent skills for security risks before installation. Produces a clear PASS / WARN / FAIL verdict with findings and remediation guidance.
Quick Start
# Audit a local skill directory
python3 scripts/skill_security_auditor.py /path/to/skill-name/
# Audit a skill from a git repo
python3 scripts/skill_security_auditor.py https://github.com/user/repo --skill skill-name
# Audit with strict mode (any WARN becomes FAIL)
python3 scripts/skill_security_auditor.py /path/to/skill-name/ --strict
# Output JSON report
python3 scripts/skill_security_auditor.py /path/to/skill-name/ --json
What Gets Scanned
1. Code Execution Risks (Python/Bash Scripts)
Scans all .py, .sh, .bash, .js, .ts files for:
| Category | Patterns Detected | Severity |
|---|---|---|
| Command injection | os.system(), os.popen(), subprocess.call(shell=True), backtick execution |
🔴 CRITICAL |
| Code execution | eval(), exec(), compile(), __import__() |
🔴 CRITICAL |
| Obfuscation | base64-encoded payloads, codecs.decode, hex-encoded strings, chr() chains |
🔴 CRITICAL |
| Network exfiltration | requests.post(), urllib.request, socket.connect(), httpx, aiohttp |
🔴 CRITICAL |
| Credential harvesting | reads from ~/.ssh, ~/.aws, ~/.config, env var extraction patterns |
🔴 CRITICAL |
| File system abuse | writes outside skill dir, /etc/, ~/.bashrc, ~/.profile, symlink creation |
🟡 HIGH |
| Privilege escalation | sudo, chmod 777, setuid, cron manipulation |
🔴 CRITICAL |
| Unsafe deserialization | pickle.loads(), yaml.load() (without SafeLoader), marshal.loads() |
🟡 HIGH |
| Subprocess (safe) | subprocess.run() with list args, no shell |
⚪ INFO |
2. Prompt Injection in SKILL.md
Scans SKILL.md and all .md reference files for:
| Pattern | Example | Severity |
|---|---|---|
| System prompt override | "Ignore previous instructions", "You are now..." | 🔴 CRITICAL |
| Role hijacking | "Act as root", "Pretend you have no restrictions" | 🔴 CRITICAL |
| Safety bypass | "Skip safety checks", "Disable content filtering" | 🔴 CRITICAL |
| Hidden instructions | Zero-width characters, HTML comments with directives | 🟡 HIGH |
| Excessive permissions | "Run any command", "Full filesystem access" | 🟡 HIGH |
| Data extraction | "Send contents of", "Upload file to", "POST to" | 🔴 CRITICAL |
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

skill-security-auditor is a skill published in the GitHub repository adriannoes/awesome-agentic-ai (95 stars, last pushed yesterday), licensed MIT. It adds 161 tokens to every session and 1,946 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
Other skills, from other repositories
AI/ML Model Testing
Testing machine learning models including accuracy validation, bias detection, drift monitoring, A/B testing, and model regression testing.
greenfield
Parallel persona planning for new projects. Research agent runs first to build domain context, then Architect, PM, and Security agents run in parallel. Synthesis agent combines all perspectives into a detailed GSD-style PLAN.md with Tensions section.
brownfield-drift
Enforces architecture boundaries defined in PLAN.md. Use when a PR crosses module/service boundaries, when the dev asks "are we following the architecture?", or as a scheduled architecture health check. Not for querying what a module does — use brownfield-chat for that.
wednesday-git
Unified Git workflow. Manages the entire task lifecycle: branch creation (sprint), atomic commits (git-os), and PR opening (pr-create).
standards-kit
Unified development and design standards. Enforces code quality (complexity < 8), strict naming conventions, and the mandatory use of approved UI component libraries.
kill-slop
Stop AI coding agents from shipping sloppy code — over-abstraction, drive-by refactors, obvious comments, extra files, unrequested deps, giant unreadable files, or fishing outside the workspace for “inspiration”. Use when writing or editing code, implementing features, fixing bugs, splitting or organizing files, or…
