control-mapping

A mapping skill that connects NIST SP 800-53 security controls with FedRAMP requirements and guidance documents. It also groups controls into families such as access control, auditing, and incident response.

In plain words
What is it for?
Use it to map controls by family or ID, find references in guidance documents, review implementation advice, and identify relevant control enhancements.
Why use it?
It reduces the work of cross-referencing security standards and highlights gaps or FedRAMP-specific considerations.

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

control-mapping 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 3d 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 mapping controls:

  1. Cross-reference NIST SP 800-53 control definitions with FedRAMP MAS/ADS/VDR documents
  2. Identify baseline control families (AC, AU, CA, CM, CP, IA, IR, MA, MP, PE, PL, PM, PS, RA, SA, SC, SI, SR)
  3. Show control-to-document guidance relationships
  4. Flag any control gaps or special FedRAMP-specific considerations
  5. Provide implementation examples from FedRAMP guidance
  6. Include control enhancements where applicable

Use the fedramp-docs MCP server tools:

  • list_controls to get control mappings filtered by family or control ID
  • grep_controls_in_markdown to find control references in guidance docs
  • search_markdown to find implementation guidance
  • get_significant_change_guidance for change-related controls
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.

control-mapping is a skill published in the GitHub repository hackIDLE/fedramp-docs-mcp (18 stars, last pushed 4mo ago), licensed MIT. It adds 35 tokens to every session and 222 once invoked, about $0.0002 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 2026-08-30.
