feat(skills): add /prune-memory — curate .claude/memory/ registries
New personal skill to maintain memory registry hygiene. Gap identified between existing tools: - /caveman:compress — text-compresses one file, no curation - /close — appends new entries end-of-session, doesn't prune - /prune-memory (new) — audits, classifies, applies user-approved cleanup Operations: - Mark obsolete entries `status: superseded by <ID>` or `status: deprecated` (no hard delete — append-only per CLAUDE.md memory rule). - Merge similar entries (new ID, sources marked superseded). - Caveman-compress bloated prose-heavy entries inline. - Repair Index drift (missing rows, orphaned rows). Workflow: STEP 0 precheck (refuses dirty working tree, git = backup) → STEP 1 audit (A obsolete / B similar / C bloated / D drift) → STEP 2 plan + mandatory user approval → STEP 3 apply safe→destructive → STEP 4 verify Index sanity + line-count report. Follows superpowers:writing-skills CSO conventions: "Use when..." trigger description (under 1024-char spec), Quick Reference table, Common Mistakes table, Failure Paths table. v1 ships without baseline TDD test (noted in skill body); STEP 2 approval gate is the safety net.

Use when .claude/memory/ registries grow too large or noisy — superseded
|
||||||
|
entries verbose, similar entries cluttering, journal stale, caveman style
|
||||||
|
drifted. Curates the 5 registries via mark-superseded + merge + inline
|
||||||
|
caveman compression. Append-only safe (no hard delete). Git is the backup.

# /prune-memory — Memory registry curation
|
||||||
|
|
||||||
|
Operates on `.claude/memory/` in the current project (CWD). Curates the
|
||||||
|
5 registries: `decisions.md`, `learnings.md`, `blockers.md`, `journal.md`,
|
||||||
|
`evals.md`.
|
||||||
|
|
||||||
|
## Core principles
|
||||||
|
|
||||||
|
- **Git is the backup.** Skill writes in-place. PRECHECK refuses to run
|
||||||
|
if working tree dirty on registry files.
|
||||||
|
- **Append-only friendly.** Marks entries `status: superseded by <new-ID>`
|
||||||
|
or `status: deprecated` instead of deleting. Body of old entry stays
|
||||||
|
for history.
|
||||||
|
- **IDs stable.** Never renumber. Merges create a new ID; sources keep
|
||||||
|
their ID with superseded status.
|
||||||
|
- **Caveman style enforced.** Per CLAUDE.md memory rule, all writes are
|
||||||
|
caveman-style English. Compression rewrites prose to fragments.
|
||||||
|
- **User approves every category.** No silent changes.
|
||||||
|
|
||||||
|
## Quick reference
|
||||||
|
|
||||||
|
| When | Use |
|
||||||
|
|------|-----|
|
||||||
|
| Add new entry this session | `/close` |
|
||||||
|
| Token-compress one file (not curating) | `/caveman:compress <file>` |
|
||||||
|
| Curate: obsolete + merge + caveman | `/prune-memory` (this skill) |
|
||||||
|
|
||||||
|
## STEP 0 — PRECHECK
|
||||||
|
|
||||||
|
```bash
|
||||||
|
test -d .claude/memory/ || { echo "no .claude/memory/ in $(pwd)"; exit 1; }
|
||||||
|
git status --short .claude/memory/ 2>/dev/null
|
||||||
|
```
|
||||||
|
|
||||||
|
If working tree is dirty on any registry file → STOP with: "Commit or
|
||||||
|
stash pending changes in `.claude/memory/` first. Skill writes in-place.
|
||||||
|
Git is the only backup."
|
||||||
|
|
||||||
|
## STEP 1 — AUDIT (per registry)
|
||||||
|
|
||||||
|
For each target registry (filter by `$ARGUMENTS` or all 5):
|
||||||
|
|
||||||
|
Read file. Classify candidates into A/B/C/D below. Use today's date for
|
||||||
|
age comparisons. Today's date is in the system context.
|
||||||
|
|
||||||
|
### A. Obsolete — mark-superseded candidates
|
||||||
|
- Decisions `status: proposed` older than 90 days → propose
|
||||||
|
`status: deprecated` (no follow-up).
|
||||||
|
- Decisions whose body contains "superseded by <ID>" but Index row still
|
||||||
|
says `accepted` → propose Index row fix to
|
||||||
|
`superseded by <that-ID>`.
|
||||||
|
- Blockers `status: open` whose root cause matches a commit in last 30
|
||||||
|
days (grep `git log --since=30.days --grep=<keyword>`) → propose
|
||||||
|
`status: resolved` with commit ref.
|
||||||
|
- Journal entries older than 180 days with zero cross-reference from
|
||||||
|
later entries → propose collapse into 1-line month summary
|
||||||
|
(`## YYYY-MM` heading replaces detail).
|
||||||
|
|
||||||
|
### B. Similar — merge candidates
|
||||||
|
- Two+ entries sharing root keyword in title (e.g. `pandoc`,
|
||||||
|
`client-handover`, `CSS overlay`).
|
||||||
|
- Shared file paths in `**Reference**:` lines.
|
||||||
|
- Same week + adjacent IDs + same domain.
|
||||||
|
- Use semantic judgment on overlap; don't merge complementary entries
|
||||||
|
that cover different angles of one concept.
|
||||||
|
|
||||||
|
### C. Bloated — inline caveman-rewrite candidates
|
||||||
|
- Body > 150 words AND prose-heavy.
|
||||||
|
- Detect filler density: count `\b(the|a|an|just|really|basically|actually|simply)\b`
|
||||||
|
matches; if > 5% of word count → bloated.
|
||||||
|
|
||||||
|
### D. Index drift
|
||||||
|
- Body `## (BDR|LRN|BLK|EVAL)-NNN` heading exists but no matching row
|
||||||
|
in `## Index` table → propose Index backfill.
|
||||||
|
- Index row exists but body entry missing → propose `status: deleted
|
||||||
|
(orphaned)` tombstone or removal of Index row (user decides).
|
||||||
|
|
||||||
|
## STEP 2 — PRESENT PLAN ★ MANDATORY STOP
|
||||||
|
|
||||||
|
Print one block per registry. Example:
|
||||||
|
|
||||||
|
```
|
||||||
|
PRUNE PLAN — decisions.md (N entries → M after if approved)
|
||||||
|
|
||||||
|
[A. Obsolete — mark superseded]
|
||||||
|
BDR-003 — Gitignore wildcard pattern — status: proposed since 2026-03-12
|
||||||
|
→ mark: status: deprecated (no follow-up after 90 days)
|
||||||
|
BDR-011 — Client handover 4-chapter — body says superseded by BDR-013
|
||||||
|
→ fix Index: status = "superseded by BDR-013"
|
||||||
|
|
||||||
|
[B. Similar — merge]
|
||||||
|
LRN-014 + LRN-016 — both pandoc rendering quirks
|
||||||
|
→ propose: merge into NEW LRN-017 ("Pandoc rendering quirks")
|
||||||
|
with both bodies appended + caveman pass; sources marked
|
||||||
|
status: superseded by LRN-017
|
||||||
|
|
||||||
|
[C. Bloated — inline caveman rewrite]
|
||||||
|
BDR-011 — body 612 words, filler density 7.2% → ~380 expected (-38%)
|
||||||
|
|
||||||
|
[D. Index drift]
|
||||||
|
(none)
|
||||||
|
|
||||||
|
Approve per category? (all / a / b / c / d / edit <ID> / skip)
|
||||||
|
```
|
||||||
|
|
||||||
|
Wait for user input. Default = nothing applied.
|
||||||
|
|
||||||
|
## STEP 3 — APPLY APPROVED CHANGES
|
||||||
|
|
||||||
|
Order: safe → destructive.
|
||||||
|
|
||||||
|
1. **Index drift fixes** — no body changes. Backfill missing rows, mark
|
||||||
|
orphans.
|
||||||
|
2. **Status flag updates** — Index row status field only. Body untouched.
|
||||||
|
3. **Merges** — write new merged entry (next-free ID); source IDs marked
|
||||||
|
`status: superseded by <new-ID>` in Index (body kept verbatim for
|
||||||
|
history). Merged body:
|
||||||
|
- Preserves all `**Reference**:` lines (dedupe identical paths).
|
||||||
|
- Caveman pass on prose during merge.
|
||||||
|
- Keeps frontmatter fields: id (new), date (today), title, status
|
||||||
|
(accepted), references (union).
|
||||||
|
4. **Inline caveman compression** — preserve frontmatter exactly (id,
|
||||||
|
date, title, status, references). Rewrite prose body to fragments:
|
||||||
|
- Drop articles (`a`, `an`, `the`).
|
||||||
|
- Drop filler (`just`, `really`, `basically`, `actually`, `simply`).
|
||||||
|
- Short synonyms (`big` not `extensive`, `fix` not `implement a solution for`).
|
||||||
|
- Keep code blocks, URLs, error messages, file paths VERBATIM.
|
||||||
|
- Keep IDs (BDR-XXX, LRN-XXX, commit hashes) verbatim.
|
||||||
|
|
||||||
|
After each write, regenerate Index from body when rows changed.
|
||||||
|
|
||||||
|
## STEP 4 — VERIFY
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# All body entries have Index rows; no orphans
|
||||||
|
for f in .claude/memory/decisions.md .claude/memory/learnings.md .claude/memory/blockers.md; do
|
||||||
|
prefix=$(basename "$f" .md | tr a-z A-Z | cut -c1-3)
|
||||||
|
/usr/bin/grep -oE "^## (${prefix})-[0-9]+" "$f" | while read marker; do
|
||||||
|
id="${marker##\#\# }"
|
||||||
|
/usr/bin/grep -q "^| ${id} " "$f" || echo "MISSING INDEX: $id in $f"
|
||||||
|
done
|
||||||
|
/usr/bin/grep -oE "^\| (${prefix})-[0-9]+ " "$f" | while read row; do
|
||||||
|
id=$(echo "$row" | awk '{print $2}')
|
||||||
|
/usr/bin/grep -q "^## ${id} " "$f" || echo "ORPHAN INDEX: $id in $f"
|
||||||
|
done
|
||||||
|
done
|
||||||
|
|
||||||
|
wc -l .claude/memory/*.md
|
||||||
|
```
|
||||||
|
|
||||||
|
Report:
|
||||||
|
|
||||||
|
```
|
||||||
|
PRUNE COMPLETE
|
||||||
|
decisions.md : 226 → 184 lines (-19%)
|
||||||
|
learnings.md : 190 → 165 lines (-13%)
|
||||||
|
blockers.md : no candidates
|
||||||
|
journal.md : 88 → 62 lines (-30%)
|
||||||
|
evals.md : no candidates
|
||||||
|
|
||||||
|
INDEX SANITY: OK
|
||||||
|
NEXT: review `git diff .claude/memory/`, then `/commit-change`
|
||||||
|
```
|
||||||
|
|
||||||
|
## What NOT to prune
|
||||||
|
|
||||||
|
- Journal entries < 30 days old.
|
||||||
|
- Decisions / learnings with commit references < 14 days old.
|
||||||
|
- Entries the user marked `status: accepted` in the current session.
|
||||||
|
- The current session's just-capitalized entries (read `journal.md`
|
||||||
|
tail to identify them).
|
||||||
|
|
||||||
|
## Common mistakes
|
||||||
|
|
||||||
|
| Mistake | Fix |
|
||||||
|
|---------|-----|
|
||||||
|
| Renumbering IDs after a merge | IDs are stable. Sources keep their ID + `status: superseded`. New merged entry gets next-free ID. |
|
||||||
|
| Hard-deleting "obsolete" entries | Forbidden by append-only rule. Use `status: deprecated`. Body stays. |
|
||||||
|
| Compressing code blocks / URLs / error messages | Caveman compression touches PROSE only. Code, URLs, IDs, error quotes stay verbatim. |
|
||||||
|
| Running on a dirty working tree | PRECHECK blocks this. Commit first. |
|
||||||
|
| Compressing the current session's journal entry | Excluded by "What NOT to prune" — current session capitalization is still useful. |
|
||||||
|
| Merging complementary entries that cover different angles | Merge only when same concept, same scope. Different angles = keep separate. |
|
||||||
|
|
||||||
|
## Failure paths
|
||||||
|
|
||||||
|
| Situation | Behavior |
|
||||||
|
|---|---|
|
||||||
|
| `.claude/memory/` missing | STOP: `no .claude/memory/ in current directory; run from project root` |
|
||||||
|
| Working tree dirty on registry files | STOP per PRECHECK; tell user to commit/stash first |
|
||||||
|
| User says `skip` at STEP 2 | Exit cleanly, no writes |
|
||||||
|
| Merge produces an entry > 600 words | Re-split — merge was too greedy. Re-prompt user to keep separate. |
|
||||||
|
| Index sanity FAILED at STEP 4 | Print exact missing/orphan IDs. Do NOT auto-fix — user re-runs or hand-edits. |
|
||||||
|
| Caveman compression result < 20% of original AND original had code blocks | Revert that entry's compression — flag as needing manual rewrite (likely stripped technical detail). |
|
||||||
|
| Same file already compressed in same session (e.g. via `/caveman:compress`) | Skip C-category for that file; warn user that double-pass risks technical drift. |
|
||||||
|
|
||||||
|
## Rules
|
||||||
|
|
||||||
|
- No silent writes — every change goes through STEP 2 approval gate.
|
||||||
|
- No renumbering — IDs are stable across all operations.
|
||||||
|
- No hard delete in v1 — only mark superseded. (Hard delete opt-in may
|
||||||
|
arrive in v2 if explicit demand surfaces.)
|
||||||
|
- Working tree must be clean before any write — git is the only backup.
|
||||||
|
- Caveman compression touches prose only; code/URLs/error quotes
|
||||||
|
verbatim per CLAUDE.md memory format rule.
|
||||||
|
|
||||||
|
## TDD note (skill itself)
|
||||||
|
|
||||||
|
v1 ships without baseline test scenarios per superpowers:writing-skills
|
||||||
|
Iron Law. Recommended before relying on the skill in production:
|
||||||
|
|
||||||
|
1. RED: spawn subagent, give it a real `.claude/memory/` snapshot, ask
|
||||||
|
"prune obsolete entries". Document what it does naturally.
|
||||||
|
2. GREEN: invoke `/prune-memory` on the same snapshot. Verify it
|
||||||
|
follows STEP 0–4 + respects append-only rule.
|
||||||
|
3. REFACTOR: log any new rationalizations the subagent finds; add
|
||||||
|
counters to the "Common mistakes" / "Failure paths" tables.
|
||||||
|
|
||||||
|
Until TDD is done, the skill is v1-untested. STEP 2 approval gate is
|
||||||
|
the human safety net.
