Find and merge duplicate or near-duplicate notes anywhere in a vault (rules, concepts, people, leads) with a deterministic scanner and a supersede-not-delete merge policy. Human review before any merge is written. Triggers: "/dedup", "clean up duplicates", "dedupe <folder>".
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
# /dedup — find & merge duplicates (supersede, never delete) > 🧒 **When reporting to a non-technical operator:** end with a child-simple "In plain words" recap in their language. ## 🖥️ Dashboard first (the operator works visually) `python "$IMPORTS_ROOT/build_dedup_dashboard.py"` (it runs the scan itself) → open `$OBSIDIAN_VAULT/_Dashboards/Dedup-Dashboard.html`: candidate clusters by topic, colour = similarity (🔴 ≥0.7 almost certainly a duplicate); each cluster shows which note to keep (the newer one) and which becomes superseded. DISPLAY ONLY; merging is done by hand below (supersede, never delete). Complementary notes are left alone. ## Step 1 — Scan (deterministic; AK-47, ~free; token law) `python "$IMPORTS_ROOT/dedup_scan.py"` → scans ACTIVE notes by theme, difflib similarity → candidate clusters in `$IMPORTS_ROOT/dedup_report.txt`. For a DIFFERENT folder, copy the script and change its `OPS` path. Start at similarity ≥0.5 (high-confidence), then ≥0.4 for the next tier — **loop-until-dry** (stop when remaining clusters are complementary/noise). ## Step 2 — Judge each cluster (NOT every look-alike is a dup) …

How to install
mdr add tonydzi/second-brain-starter-kit/dedup@sha256:7ecc16d28845331aThe line at the top of this page pins the label git:20261020.402f6b7, 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.
