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 | $0.02913 |
| Opus 5 | $0.00068 | $0.01456 |
| Sonnet 5 | $0.00027 | $0.00583 |
| Haiku 4.5 | $0.00014 | $0.00291 |
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 8d 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 — 210 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).
Methodology
Step 1 — Establish scope
CSF assessments are scope-bounded. Decide which of these you're assessing:
- Whole organization — every system, every business unit
- One product / service — for vendor due-diligence questionnaires (SIG, CAIQ)
- One environment — production cloud only, or PCI-in-scope only
- Regulatory scope — HIPAA-covered systems, FedRAMP boundary, etc.
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 (383 stars, last pushed 3mo ago), licensed MIT. It adds 135 tokens to every session and 2,913 once invoked, about $0.0007 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 2026-08-30.
