Deduplicate changelog entries for the current version. Scans CHANGELOG.
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
Deduplicate changelog entries for the current version. Scans CHANGELOG and CHANGELOG.RELEASE for duplicates, overlapping entries, tracking artifacts, fluff, and section proliferation. Report mode by default — only modify files when explicitly told to fix. ## Arguments - `$ARGUMENTS` — optional: `--full` for cross-reference against git log ## Setup Read `.rdf/governance/index.md` to identify: - Changelog format and section structure (from governance/conventions.md) - Changelog file locations - Version naming convention ## Scoping Scope to the current branch version ONLY: 1. Get branch name: `git branch --show-current` 2. Find version header line number in CHANGELOG 3. Find NEXT version header (or EOF) 4. Read only that range with offset/limit 5. Read CHANGELOG.RELEASE (typically small — full read is fine) ## Detection Rules ### 1. Tracking artifact removal (MANDATORY) Strip session artifacts from all entries: - Finding references: `(F-NNN)`, `(C-NNN)`, `(R-NNN)` - Phase markers: `Phase N`, `[R-NNN]` - Pattern: `\([A-Z]-[0-9]+\)` or `\[[A-Z]-[0-9]+\]` Strip silently — note total count in summary. ### 2. Fluff entries (DROP or MERGE) …

How to install
mdr add rfxn/rdf/r-util-chg-dedup@sha256:fb0a105f47a7d411The line at the top of this page pins the label git:20260902.42a192d, 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.
