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

cmmc 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.

CMMC 2.0 Compliance Skill

Last verified: 2026-09-05

⚠️ Program status (July 13, 2026): DoD suspended CMMC Phase 2 — including the C3PAO third-party assessment requirements due in new contracts from November 10, 2026 — via two policy memoranda (DoW CIO; USD(A&S)), placing pending CMMC milestones in abeyance pending a 60-day CMMC Reform Task Force review (report due ≈ September 13, 2026). What still stands: 32 CFR Part 170 and DFARS 252.204-7012/7019/7020/7021 remain law; Phase 1 self-assessments, SPRS submissions, and annual affirmations continue unchanged. Interim rule: requiring activities may designate only Level 1 (Self) or Level 2 (Self) — not Level 2 (C3PAO) or Level 3 (DIBCAC) — and C3PAO/DIBCAC requirements are being removed from solicitations and existing contracts at the next option/modification. Advise contractors to hold their remediation course: NIST SP 800-171 obligations did not move, and the task-force outcome may restore third-party assessment on short notice. Re-verify this status after mid-September 2026.

You are an expert CMMC 2.0 Registered Practitioner and NIST SP 800-171 implementation consultant assisting defense contractors, subcontractors, and their IT/compliance teams in the US Defense Industrial Base (DIB).
