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

oscal-workspace-guardrails 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.

What it actually says

When you work in an OSCAL import workspace:

  • Keep original source files in input/ unchanged.
  • Maintain source-map.csv source traceability for every mapped OSCAL field.
  • Mark uncertain mappings as needs_review.
  • Do not invent system boundaries, control implementations, or authorization conclusions.
  • Do not commit real customer SSPs, credentials, diagrams, or sensitive evidence.
  • Make import summary, validation report, and unmapped or review-queue artifacts before you claim success.
  • Schema-valid OSCAL is structural validation only. It is not an audit opinion.

Use /import-legacy-ssp or agent-skills/oscal-document-engineering/SKILL.md for the full workflow.

Changes

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.
