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 | $0.00188 | $0.03054 |
| Opus 5.5 | $0.00075 | $0.01222 |
| Sonnet 5.5 | $0.00038 | $0.00611 |
| Haiku 4.5 | $0.00019 | $0.00305 |
Grade A, and why
cmmc-nist-800-171 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.

CMMC NIST SP 800-171 (Level 2)
Overview
This skill implements Cybersecurity Maturity Model Certification (CMMC) 2.0 Level 2 readiness aligned to NIST SP 800-171 Revision 2 (Protecting Controlled Unclassified Information in Nonfederal Systems and Organizations, February 2020). Level 2 applies to contractors handling CUI and requires 110 security requirements (including enhanced requirements from NIST SP 800-171A assessment objectives).
| CMMC 2.0 level | NIST alignment | Assessment type |
|---|---|---|
| Level 1 | FAR 52.204-21 (17 practices) | Annual self-assessment |
| Level 2 | NIST SP 800-171 Rev 2 (110 practices) | Triennial C3PAO assessment (priority acquisitions) or self-assessment per contract |
| Level 3 | NIST SP 800-172 (advanced) | Government-led assessment |
CUI is government-created or -owned information requiring safeguarding per 32 CFR Part 2002 and the CUI Registry. Contractual obligations flow from DFARS 252.204-7012 (Safeguarding Covered Defense Information), 252.204-7019 (NIST SP 800-171 DoD Assessment), and 252.204-7020 (NIST SP 800-171 DoD Assessment Requirements).
SPRS (Supplier Performance Risk System) score:
- Submit self-assessment score to SPRS at https://piee.eb.mil/ (PIEE)
- Score calculation: −110 + (5 × MET) + (3 × NOT APPLICABLE) per DoD methodology—document each practice status
- Minimum score expectations vary by solicitation; 110 MET is target for full compliance
14 NIST 800-171 requirement families: AC, AT, AU, CM, IA, IR, MA, MP, PS, PE, RA, CA, SC, SI.
Cross-skill mapping: cloud and boundary patterns overlap fedramp-moderate-baseline; access and identity testing uses access-control-identity-audit.
Reference documents: CMMC AB, NIST SP 800-171 Rev 2, NIST SP 800-171A (assessment objectives).
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 is a skill published in the GitHub repository vaquarkhan/compliance-agent-skills (4 stars, last pushed 2mo ago), licensed MIT. It adds 188 tokens to every session and 3,054 once invoked, about $0.0008 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.
