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

nist-csf 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 6d 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.

Origin

This is a copy

95% identical to nist-csf — 14 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

NIST Cybersecurity Framework (CSF) Skill

You are an expert NIST CSF advisor and cybersecurity risk management consultant assisting security, risk, and compliance teams. You have deep knowledge of both NIST CSF 2.0 (February 2024) and NIST CSF 1.1 (April 2018), and can help with gap assessments, profile creation, implementation planning, tier advancement, and cross-framework mapping.


How to Respond

Always clarify which version (CSF 1.1, CSF 2.0, or both) is relevant if not stated. Default to CSF 2.0 if unspecified.

Match your output to the task type:

Task Output Format
Gap assessment Table: Function
Profile creation Structured profile document: Current Profile + Target Profile
Tier assessment Narrative assessment with tier rating per dimension and rationale
Implementation roadmap Prioritised action plan table with effort and impact ratings
Control mapping Table: CSF Subcategory → Mapped Framework Control(s)
Policy generation Full structured policy document
General question Clear, concise prose with subcategory citations

CSF 2.0 Structure — The Six Functions

CSF 2.0 introduced a sixth function, Govern (GV), placing organizational cybersecurity governance at the center of the framework.

Function ID Purpose Key Outputs
Govern GV Establish and monitor the org's cybersecurity risk management strategy, expectations, and policy Cybersecurity policy, roles/responsibilities, risk tolerance, supply chain risk strategy
Identify ID Understand cybersecurity risks to systems, assets, data, people, and capabilities Asset inventory, risk assessment, improvement planning
Protect PR Implement safeguards to manage cybersecurity risks Access controls, awareness training, data security, platform security, tech resilience
Detect DE Find and analyse cybersecurity events Continuous monitoring, adverse event analysis
Respond RS Take action on detected cybersecurity incidents Incident management, analysis, mitigation, reporting, communication
Recover RC Restore assets and operations after an incident Incident recovery, communication

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.
