security-scan

security-scan is a skill for Claude Code from jason21wc/ai-governance-mcp. It costs 81 tokens per session (458 once invoked), scanned A, original, Apache-2.0.

A skill for checking a codebase for exposed secrets, risky dependencies, and basic authentication problems. Authentication is the process of verifying who a user or system is.

In plain words
What is it for?
Running focused checks for secrets, dependency vulnerabilities, and basic authentication weaknesses, with evidence for reported findings.
Why use it?
It catches common security issues such as leaked keys, vulnerable packages, and hardcoded or missing credentials before they cause harm.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

security-scan 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 11d 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.

What it actually says

Runtime Context

After the skill loads, establish the project root, branch, dependency manifests, and relevant authentication/configuration surfaces with ordinary read-only calls.

Instructions

You are running a focused security scan. Collect the Runtime Context above, then read procedure.md in this skill folder for the full scanning protocol.

Scope

This skill covers the most mechanical, portable security concerns:

  1. Secrets detection — API keys, tokens, passwords, private keys in code and config
  2. Dependency audit — known vulnerabilities in project dependencies
  3. Basic auth patterns — hardcoded credentials, default passwords, missing auth

For deeper analysis (full OWASP systematic review, attack surface mapping, data flow tracing), perform a comprehensive manual security review with project-specific context.

Execution Protocol

  1. Read procedure.md for the full scanning procedure.
  2. Execute all three scan phases in order.
  3. Present findings with severity gating — CRITICAL and HIGH findings first.
  4. Every finding needs evidence — file:line + quoted code, or it's dropped.

Portability Note

Slash-command references (e.g. /code-review) name companion skills. On hosts where a named skill isn't installed, perform the equivalent manually instead of invoking it.

Output Defaults

  • Severity gating: CRITICAL and HIGH shown prominently; MEDIUM and LOW summarized
  • Evidence required: Every finding must cite file:line + quoted code
  • Actionable fixes: Each finding includes a specific remediation step
Files

What ships with it

1 file 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.

Changes

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.
