What it does
Skill Security Auditor is an agent skill from mohitagw15856/pm-claude-skills. Audit a Claude/Agent SKILL.md (or any AI skill / system prompt) for safety before installing or merging it. Use when asked to review a skill for security, check a prompt for injection, vet a community skill, or assess whether an instruction file is safe to run. Produces a risk-rated report of findings (prompt injection, data exfiltration, code execution, secrets, hidden text) with severity, evidence, and a clear install / don't-install recommendation.
Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `references/injection-patterns.md`, `references/worked-example.md` and `templates/audit-report.md`).
It sits in Security, covering Prompt injection and agent security and Prompt engineering. The repository describes itself as: 1255 professional Agent Skills for Claude, ChatGPT, Gemini, Cursor & Codex — PRDs, postmortems, leases, medical bills, layoffs, go-bags, new countries. Plain markdown, MIT, in… The licence is MIT.
When your agent uses it
- Asked to review a skill for security
- Check a prompt for injection
- Vet a community skill
- Assess whether an instruction file is safe to run
Example prompts
- “/skill-security-auditor”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Read the skill body and every bundled script — scripts are where real harm hides.
- For each finding, capture: category, severity, the exact line/snippet (evidence), and why it's risky.
- Decide an overall verdict: Safe to install, Install with caution (medium issues to review), or Do not install (any high-severity issue).
- For a repo, recommend automation: run node scripts/skill-audit.mjs in CI to gate every PR.
What it can do on your machine
Read from SKILL.md and the folder at commit 1cbf1f0. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
nodecurl
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use curl, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Skill Security Auditor loads about 1.5k tokens when it runs, and up to ~3.9k if it reads all its reference files. Until then it costs about 120 tokens; SKILL.md has 757 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- description
- Audit a Claude/Agent SKILL.md (or any AI skill / system prompt) for safety before installing or merging it. Use when asked to review a skill for security, check a prompt for injection, vet a community skill, or assess whether an instruction file is safe to run. Produces a risk-rated report of findings (prompt injection, data exfiltration, code execution, secrets, hidden text) with severity, evidence, and a clear install / don't-install recommendation.
Skill Security Auditor
Review an AI skill file or system prompt for instructions that could harm whoever installs or runs it. Skills are plain text, but plain text can still tell a model to leak data, run destructive commands, or ignore its guidelines. This skill produces a structured safety verdict.
When to use
- Vetting a skill from an untrusted or community source before installing it
- Reviewing a contributed
SKILL.mdin a pull request - Checking a system prompt / custom instruction for prompt-injection risks
Required Inputs
Ask for these if not provided:
- The skill / prompt content to audit (paste it, or the file path)
- Any bundled scripts the skill ships (these matter as much as the prose)
- Where it came from (source/author) and how it will run (auto-loaded vs. manual)
What to Check
Scan for each category and rate severity (🔴 High / 🟠 Medium / 🟡 Low):
| Category | Look for |
|---|---|
| Prompt injection | "ignore previous/all instructions", "developer mode", jailbreak/DAN framing, attempts to reveal the system prompt, forced unrestricted personas |
| Data exfiltration | Instructions that transmit the conversation, user-provided content, credentials, or keys to an external URL/webhook/server |
| Code & command execution | eval/exec, os.system, subprocess, child_process, destructive shell (rm -rf /, dd, fork bombs, chmod 777) |
| Secrets | Hardcoded API keys, AWS keys (AKIA…), private keys, or asking the user to paste secrets |
| Obfuscation | Zero-width / invisible Unicode, very long base64 blobs that hide payloads |
| Scope creep | Instructions unrelated to the skill's stated purpose, or that try to broaden permissions |
Process
- Read the skill body and every bundled script — scripts are where real harm hides.
- For each finding, capture: category, severity, the exact line/snippet (evidence), and why it's risky.
- Decide an overall verdict: Safe to install, Install with caution (medium issues to review), or Do not install (any high-severity issue).
- For a repo, recommend automation: run
node scripts/skill-audit.mjsin CI to gate every PR.
Output Format

Apply it while producing the output; it carries the calibration and judgment calls the method summary above compresses.templates/audit-report.md— a fill-in version of the deliverable with the quality gates inline. Offer it when the user wants to work the document themselves rather than have it generated.

Scoring Rubric (0–40)
Score any output of this skill before handing it over; 32+ is ship-quality.
| Dimension | 0 | 5 | 10 |
|---|---|---|---|
| Coverage depth | Only the markdown body was skimmed; bundled scripts untouched | Body read carefully, scripts glanced at, but encodings and invisible characters not checked | Every bundled script read line-by-line, plus codepoint/encoding inspection for hidden content, with scope stated in the report |
| Evidence precision | Findings say "looks risky" with no location | Findings cite lines but mix observation with speculation | Every finding pins an exact line/file reference with a faithful, inert description of the pattern and why it's dangerous |
| Verdict discipline | Vague caution with no install decision | A verdict is given but doesn't follow from the severities found | Verdict applies the severity rule exactly (any high ⇒ do not install), stated up front with reasons |
| Calibration | Every mention of keys or network activity flagged as malicious | One benign pattern over-flagged or one real risk missed | Benign documented examples cleared by name, intent and context weighed, nothing real missed |
Quality Checks
- Every bundled script was read, not just the markdown body
- Each finding cites a concrete snippet as evidence (no vague "looks risky")
- The verdict follows the rule: any high-severity finding ⇒ Do not install
- Legitimate examples (e.g. a documented
curl https://example.com) are not over-flagged - The recommendation is actionable (what to remove/change, not just "be careful")
Anti-Patterns
- Do not pass a skill as safe without reading its scripts — prose can look clean while a script exfiltrates data
- Do not treat every mention of "API key" or "curl" as malicious; weigh intent and context
- Do not give a vague verdict — always land on install / caution / do-not-install with reasons
- Do not ignore zero-width or invisible characters; they are a classic way to hide instructions
- Do not assume a high star count or popular author means a skill is safe — audit the content itself
Example Trigger Phrases
- "Review a skill for security."
- "Check a prompt for injection."
- "Vet a community skill."
- "Assess whether an instruction file is safe to run."
