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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00096 | $0.04065 |
| Opus 5 | $0.00048 | $0.02032 |
| Sonnet 5 | $0.00019 | $0.00813 |
| Haiku 4.5 | $0.00010 | $0.00407 |
Grade A, and why
cmmc-nist-800-171-ngfw-compliance 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 12d 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 — 235 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CMMC / NIST 800-171 NGFW Compliance Research
Overview
Use this skill to answer questions like “what does an NGFW need to do for CMMC Level 2?” or “is this firewall design sufficient for NIST 800-171 boundary protection around CUI?” The core answer is: a next-generation firewall is not CMMC compliant by itself. CMMC and NIST SP 800-171 are assessed against the contractor environment, the systems that store, process, or transmit Controlled Unclassified Information (CUI), and the policies, procedures, people, evidence, and technical controls used to protect that CUI.
An NGFW can be a major supporting control. It can enforce CUI enclave segmentation, boundary protection, default-deny access, remote-access restrictions, external connection control, secure administrative access, IDS/IPS, threat prevention, logging, and incident response visibility. It only supports CMMC/NIST 800-171 when it is selected through risk and scope decisions, configured according to documented policy, monitored, reviewed, maintained, and tied to System Security Plan (SSP), assessment objective, and remediation evidence.
Treat this as research and assessment guidance, not legal advice and not a C3PAO, assessor, DoD, or contracting-officer determination. When producing formal compliance language, cite NIST SP 800-171 requirement IDs and CMMC practice language where applicable, label assumptions, and defer final interpretation to the organization’s CMMC lead, compliance team, legal counsel, prime/customer, or authorized assessor.
Runtime intake
Before starting the workflow, inspect the request, supplied artifacts, and
available approved read-only evidence. If unresolved facts could materially
change safety, scope, correctness, confidence, or the requested output, read
references/runtime-intake.md.
For each unresolved material fact whose catalog condition is true, invoke Claude AskUserQuestion or Codex request_user_input before continuing or issuing an open-ended request.
Ask at most three single-select catalog questions per round. After each response, ask another round whenever any unresolved material catalog condition remains true; continue only when none remain. Do not repeat answered questions or show the full catalog.
Without a native tool, present each selected catalog question with its 2-3 labeled choices and a free-text Other path in concise plain text; do not substitute a generic checklist.
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

cmmc-nist-800-171-ngfw-compliance is a skill published in the GitHub repository fastrevmd-lab/fwskillsshare (9 stars, last pushed today), licensed MIT. It adds 96 tokens to every session and 4,065 once invoked, about $0.0005 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.
