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 | $0.00135 | $0.02970 |
| Opus 5.5 | $0.00054 | $0.01188 |
| Sonnet 5.5 | $0.00027 | $0.00594 |
| Haiku 4.5 | $0.00014 | $0.00297 |
Grade A, and why
csf-mapping 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.
How it starts
The opening of the file, as written. The whole thing — 214 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CSF Mapping — NIST Cybersecurity Framework 2.0 Posture Assessment
Translate your security posture into the language every CISO, board, auditor, and insurer already speaks. Distinct from the audit skills (which find specific issues); this skill assesses your program against a recognized framework and produces governance-ready output.
NIST CSF 2.0 is the framework that, as of 2024, replaced CSF 1.1. It added a sixth function — Govern — recognizing that the others can't work without governance backing.
The six functions:
| Function | What it covers |
|---|---|
| Govern (GV) | Cybersecurity strategy, roles, policies, oversight, supply chain risk |
| Identify (ID) | Asset inventory, business environment, risk assessment, supply chain |
| Protect (PR) | Access control, awareness, data security, baseline configurations, maintenance, protective tech |
| Detect (DE) | Continuous monitoring, anomaly detection, adverse event analysis |
| Respond (RS) | Incident management, analysis, mitigation, reporting, comms |
| Recover (RC) | Recovery planning, improvements, communications |
Each function contains Categories (e.g., PR.AA — Identity Management, Authentication, and Access Control), and each category contains Subcategories (e.g., PR.AA-01 — Identities and credentials for authorized users, services, and hardware are managed).
This skill maps your reality to those Subcategories.
Cross-references: every audit skill in this repo (they produce evidence that becomes the "current state" entries here), iam-audit (most of PR.AA), siem-detection (most of DE), incident-triage (most of RS), threat-modeling (informs ID.RA risk assessment), breach-patterns (informs ID.IM improvements from lessons learned).
Authorization
Map the user's own organization, or a client that engaged them, from evidence they provide or point you to. This skill reads policies, configs and audit output; it doesn't probe systems. Keep the evidence inside the assessment, and don't infer another organization's posture from public data.
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.

csf-mapping is a cursor rule published in the GitHub repository briiirussell/cybersecurity-skills (435 stars, last pushed today), licensed MIT. It adds 135 tokens to every session and 2,970 once invoked, about $0.0005 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 2026-08-30.
