A security assessment that detects a project's technology stack, scans its code and dependencies for vulnerabilities, and plans how to fix the risks.

In plain words
What is it for?
It is for security audits, vulnerability checks, release preparation, deployment reviews, and remediation planning.
Why use it?
It helps developers find security weaknesses such as known dependency flaws or unsafe application code before they cause problems.

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-analysis 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 385 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Security Analysis Framework

Perform a comprehensive security vulnerability scan and analysis of the current project. Identifies the technology stack, scans for vulnerabilities in source code and dependencies, assesses real-world risk with context-aware analysis, and produces an actionable remediation roadmap.

Conditional-Load Confirmation

paths: does not auto-run this skill — it only makes the skill loadable once you (Claude) have touched one of the listed manifest files with a Read, Edit, or Write tool call this session (see ADR-0012). If you then choose to invoke this skill on your own initiative because you noticed such a manifest was touched — rather than the user directly asking for /security-analysis — confirm first with AskUserQuestion:

{
  "questions": [
    {
      "question": "A dependency manifest file was changed (package.json, pyproject.toml, Cargo.toml, go.mod, requirements.txt, or Gemfile). Run a security scan now? This audits dependencies for known CVEs and may take 1-15 minutes depending on project size.",
      "header": "Security",
      "multiSelect": false,
      "options": [
        {
          "label": "Yes - dependencies only",
          "description": "Faster scan targeting the changed manifests only (--dependencies-only). Skips deep taint analysis and fuzzing methodology review."
        },
        {
          "label": "Yes - full scan",
          "description": "Complete scan: tech-stack detection, dependency audit, source-code patterns, taint analysis, and fuzzing methodology review."
        },
        {
          "label": "No",
          "description": "Nothing is scanned; you can run /security-analysis manually at any time."
        }
      ]
    }
  ]
}
  • "Yes - dependencies only": proceed with the full scan using the instructions below, passing --dependencies-only (the default for this path — faster; targets the changed manifests).
  • "Yes - full scan": proceed with the full scan using the instructions below with no --dependencies-only flag (complete scan).
  • "No": respond with "Security scan skipped. You can run /security-analysis manually at any time." and exit immediately — do not perform any scanning.

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.
