Transform narratives into a queryable decision graph.
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
# Archaeology **Transform narratives into a queryable decision graph.** Run `/narratives` first to create `.deciduous/narratives.md`. ## Step 1: Read the narratives ```bash deciduous narratives show ``` For each narrative, you'll create a subgraph. ## Step 2: Create root goals For each narrative, create a backdated goal: ```bash deciduous add goal "<Narrative title>" -c 90 --date "YYYY-MM-DD" ``` ## Step 3: Build initial approaches ```bash deciduous add decision "<First approach>" -c 85 --date "YYYY-MM-DD" deciduous link <goal> <decision> -r "Initial design" ``` ## Step 4: Create pivots with `archaeology pivot` For each **PIVOT** in a narrative, use the atomic pivot command: ```bash deciduous archaeology pivot <from_id> "<what was learned>" "<new approach>" -c 85 -r "<why it failed>" ``` This automatically creates: - observation node (what was learned) - revisit node (reconsidering the old approach) - decision node (the new approach) - All 3 linking edges - Marks the old approach as superseded Preview before executing: ```bash deciduous archaeology pivot <from_id> "observation" "new approach" --dry-run ``` ## Step 5: Connect narratives …

How to install
mdr add notactuallytreyanastasio/deciduous/archaeology@sha256:58b6c2a8af0c5113The line at the top of this page pins the label git:20260926.88df937, 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.
