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.

Made for: Claude Code.

Per session 10 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 262 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin unknown No closer match found in the catalogue.
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 today.

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

Deep Security Scan

Run a comprehensive security analysis of the project. This is the thorough version — use for pre-deploy or periodic audits.

Steps

Run each tool that is available (skip any that aren't installed):

  1. Gitleaks — full repo history: gitleaks detect --source=. --verbose
  2. Semgrep — SAST with extended rules: semgrep --config=auto --config=p/owasp-top-ten
  3. npm audit — full dependency tree: npm audit
  4. Trivy — filesystem scan: trivy fs --severity HIGH,CRITICAL .
  5. Knip — dead code and unused deps: npx knip
  6. Madge — circular dependencies: npx madge --circular --extensions ts src/

Output

Summarize findings grouped by severity:

  • 🔴 Critical — blocks deployment, must fix immediately
  • 🟡 High — should fix before next release
  • 🟢 Medium/Low — track and address when convenient

Include specific file locations, line numbers, and remediation steps for each finding.

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-scan is a command published in the GitHub repository squirrelsoft-dev/dev (14 stars, last pushed 17d ago), licensed MIT. It adds 10 tokens to every session and 262 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 2026-09-01.
