Memory Prune

Protocol

Step 0 — Resolve and read the memory set

Resolve ~/.claude/projects/<slug>/memory/, where <slug> replaces every non-alphanumeric character in the absolute current directory with -, with ls ~/.claude/projects/ | grep -Fx -- "$(pwd | sed 's|[^a-zA-Z0-9]|-|g')". If it returns zero or multiple matches, show the candidates and ask the user to choose. Read every *.md except the MEMORY.md index, including frontmatter and metadata.type; stop if none exist.

Step 1 — Load the lenses

Invoke the Skill tool to load vet-fact, place-fact, tighten-instruction, and structure-prose; this workflow owns memory dispositions.

Step 2 — Classify and score each fact

Judge coherent facts or blocks; one file can span lanes. Treat metadata.type only as a signal: user or feedback leans memory-native; project or reference leans toward guidance, state, or evidence.

For every PROMOTE or ROUTE, including README routes, record place-fact's full placement contract in the analysis; do not paste it into the repository.

Score each verdict 0.0–1.0; name the target or why memory remains the owner. Derive each file's source disposition from all its facts:

Step 3 — Present and confirm

Present every recommendation at confidence ≥ 0.70, sorted by confidence:

| # | Confidence | Memory and block | Verdict | Target | Source disposition | Why |
|---|---:|---|---|---|---|---|

Report the count below 0.70; stop if no row qualifies. KEEP rows are informational. Confirm each PROMOTE, ROUTE, or DROP before editing a target or source.

Step 4 — Apply and prove

For each approved PROMOTE or ROUTE:

1. Shape PROMOTE material with tighten-instruction, then structure-prose; preserve ROUTE material in its owner's required form.
2. Write the canonical target and required delivery views; verify the trigger, upkeep, and retirement path.

Recompute source dispositions from approved rows. DELETE removes the source; TRIM preserves unabsorbed blocks and refreshes stale frontmatter or summaries. Leave declined and below-threshold facts unchanged.

Update MEMORY.md: remove deleted sources, refresh trimmed sources, and keep - [Title](file.md) — one-line summary for all others.

Cold-read every changed source and target in full. Fix only run-caused or exposed contradictions, duplicate ownership, mixed scopes, broken routes, lost evidence, or unnecessary eager loading.

Step 5 — Report

**Memory prune:**
- Promoted: [memory block → target, one per line | none]
- Routed: [memory block → target, one per line | none]
- Kept: [memory block, one per line | none]
- Dropped: [memory block, one per line | none]
- Sources: [N deleted, N trimmed, N unchanged]
- Below threshold: [N]
