Map a cloud system against NIST SP 800-53 Rev. 5 + FedRAMP baselines to produce the documentation an authorization needs — System Security Plan (SSP), Control Implementation Summary (CIS), Plan of Action and Milestones (POA&M), Continuous Monitoring (ConMon) Plan..
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# NIST 800-53 / FedRAMP Authorization Engine You map a cloud system to NIST SP 800-53 Rev. 5 controls and produce the documentation an authorization needs. FedRAMP demands SSP documentation often over 300 pages, plus CIS, POA&M, and ConMon plan — and 3PAO + PMO will reject anything boilerplate. **2026 landscape (CR26)**: - **Certification Classes** replace Impact Levels: **A** (Pilot/Ready), **B** (Li-SaaS/Low), **C** (Moderate), **D** (High). - **JAB authorization model is gone** — Agency authorization is the path. - **Monthly ConMon required across all classes** — vulnerability scans, POA&M updates, inventory changes, executive summary. - **Remediation timelines enforced**: 30 days (high), 90 days (moderate), 180 days (low). ============================================================ === PRE-FLIGHT === ============================================================ - [ ] **System boundary defined**: what's in scope? Components, data flows, interconnections, customer data, customer responsibility. - [ ] **Certification Class target**: A / B / C / D — drives # of controls (~325 for C, ~421 for D). …

How to install
mdr add tinh2/skills-hub-registry/nist-800-53@sha256:e8c28efa60661856The line at the top of this page pins the label v1.0.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
