Safely compresses narrative Markdown using deterministic compaction plus validator checks. Only for allowlisted and gated artifacts.
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
# Markdown Compression Use this only for safe narrative Markdown or explicitly gated governance prose. This is not a general rewrite tool. ## Safe Targets - `README.md` - `docs/**/*.md` - `specs/<feature>/research.md` - `specs/<feature>/analysis-report.md` - `specs/<feature>/manual-test.md` ## Gated Targets - `.github/sddp/workflows/implement-tasks/WORKFLOW.md` - exact manifest entry; compresses only prose inside `<rules>` and `<workflow>` blocks - all other governance files require a separate manifest entry and dry-run review before compression ## Blocked Targets - `project-instructions.md`, `AGENTS.md`, `CLAUDE.md` - all unlisted workflow, agent, instruction, and wrapper Markdown under `.github/`, `.agents/`, `.claude/`, `.windsurf/`, `.opencode/`, `.codex/` - `specs/prd.md`, `specs/sad.md`, `specs/dod.md`, `specs/project-plan.md`, `specs/adrs/*.md`, `specs/plan/*.md` - feature-workspace parser-sensitive artifacts: `spec.md`, `plan.md`, `tasks.md`, `qc-report.md`, `checklists/*.md`, `autopilot-log.md` ## Process 1. Run `node scripts/compress-markdown.mjs --check <path>` to confirm the path is allowlisted or explicitly gated and validator-safe. …

How to install
mdr add attilaszasz/sdd-pilot/markdown-compression@sha256:b12dce395579564eThe line at the top of this page pins the label git:20260821.a60b53a, 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.
