security-check

A repository security-checking helper that detects the project type and runs relevant code-analysis and dependency-audit tools. It also scans for hardcoded secrets and checks whether environment files are tracked or ignored.

In plain words
What is it for?
Use it on Rails, Node, Next.js, or Python repositories to review dependencies, source code, secrets, and gitignore settings.
Why use it?
It helps find known dependency problems, static-analysis warnings, exposed credentials, and unsafe repository configuration before release.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-check 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 2d 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

Run security analysis on the current repository.

  1. Detect project type from files present (Gemfile → Rails, package.json → Node, requirements.txt → Python)

  2. Rails:

    • bundle exec brakeman --no-pager (static analysis)
    • bundle audit check --update (dependency vulnerabilities)
  3. Node/Next.js:

    • pnpm audit or npm audit
  4. All repos:

    • Scan for hardcoded secrets: grep for API keys, passwords, tokens in source files
    • Check .env files aren't tracked in git
    • Verify .gitignore covers sensitive files
  5. Report with severity levels:

    • CRITICAL: must fix now (exposed secrets, known CVEs)
    • HIGH: fix soon (security warnings)
    • MEDIUM: track (informational findings)

Threat-model verification (escalate when needed)

The scans above are tooling-level (SAST + dependency audit). For auth, permissions, or other sensitive changes — especially within a GSD project/phase — recommend escalating to gsd-secure-phase, which verifies threat mitigations against a threat model. Surface this as a recommendation; the main agent runs the skill.

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.

security-check is an agent published in the GitHub repository cveralyon/axel-setup (4 stars, last pushed 1mo ago), licensed MIT. It adds 21 tokens to every session and 309 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
