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 5.1 | $0.00046 | $0.03574 |
| Opus 5.5 | $0.00018 | $0.01430 |
| Sonnet 5.5 | $0.00009 | $0.00715 |
| Haiku 4.5 | $0.00005 | $0.00357 |
Grade A, and why
security-audit 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 1mo 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 — 396 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Purpose
Shared policy: Follow
instructions/coordination.instructions.mdfor precedence, invocation, delegation, and handoffs. Applyinstructions/workflow.instructions.mdfor proportional work and verification.
You are conducting a systematic security assessment.
This is a standalone bounded STRIDE/OWASP assessment. A security specialist in an active review can return a recommendation for it, but cannot invoke it. Start this separate workflow only after the owning workflow has ended and the user has authorized the new scope; keep this skill's own approval gate. Do not relabel a blocked review complete merely to start another workflow.
Dependency version, license, and CVE inventory belongs to
dependency-audit-report; dependency-audit coordinates optional approved
upgrades. Consume existing inventory evidence here or recommend that separate
workflow after this audit, never run a coordinator inside this skill.
Your goals are to:
- Identify security risks using structured threat modeling (STRIDE).
- Check against known vulnerability categories (OWASP Top 10).
- Rate findings by severity and exploitability.
- Provide actionable remediation recommendations with specific code fixes.
- Produce a structured security report that can be tracked and revisited.
When to use this skill
Use this skill whenever:
- A new feature is being designed or implemented that handles sensitive data or authentication.
- The user asks for a security review, audit, or assessment.
- A significant architectural change is being made (new service, new integration, new data flow).
- A regular periodic security review is due.
- A completed review recommends a separately authorized deeper STRIDE/OWASP assessment.
- A security incident has occurred and the codebase needs review.
Do not use this skill for:
- Simple code reviews (use the
code-revieweragent instead). - Pre-commit reviews (use the
git-commit-reviewskill instead). - Infrastructure-only security (partial overlap, but this skill focuses on application security).
- Dependency version, license, and CVE inventory — recommend a separate
dependency-audit-report, ordependency-auditwhen approved upgrades are also wanted.
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-audit is a skill published in the GitHub repository NickPolyder/NP.CoPilot.Config (2 stars, last pushed 1mo ago), licensed MIT. It adds 46 tokens to every session and 3,574 once invoked, about $0.0002 per session on Opus 5.5. 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.
