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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00041 | $0.00468 |
| Opus 5 | $0.00020 | $0.00234 |
| Sonnet 5 | $0.00008 | $0.00094 |
| Haiku 4.5 | $0.00004 | $0.00047 |
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 4d 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
security-scan
Trigger: dep add/update, auth/payment/DB/API/secrets/CI/release changes, or explicit user request. Skip for UI-only tasks.
- Dependency audit (detect package manager):
pnpm audit|npm audit --audit-level=moderate|bun audit|pip-audit|cargo audit|govulncheck ./... - Dependency hygiene (full audits, not single-dep adds): outdated majors (breaking risk), paid licenses (flag — never silently keep; free alternatives in
agent_docs/dep-check-guide.md), unused/bloat. - Secret scan:
gitleaks detect --source . --no-banner --redact(missing → continue with available tools). - SAST:
semgrep scan --config auto .(missing → continue). Container/filesystem:trivy fs .(missing → note it).
Output
Group findings CRITICAL → HIGH → MEDIUM → LOW. Redact all secrets, tokens, connection strings — never print raw keys, passwords, or connection strings.
Dep findings: package@version: CVE — fix | outdated majors: current→latest — breaking risk | PAID LICENSE: package — alt: X.
End with: tools run | tools missing | overall risk assessment | ESCALATE: [security-guard code review — if a critical CVE has no patch | none]
Never auto-remove or upgrade — report only. Never npm audit fix --force. Paid-license flags block until the user confirms.
Complements security-review (manual auth/payment/injection logic review) — this skill runs automated tooling only.
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 skill published in the GitHub repository mtvrkan/senior-dev-kit (5 stars, last pushed 4d ago), licensed MIT. It adds 41 tokens to every session and 468 once invoked, about $0.0002 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.
