| description | Full memory hygiene cycle — compresses memory-sessions.md, deduplicates memory-decisions.md, and syncs key project facts to the memory MCP graph. Run monthly or when context feels heavy. |
Run the following steps in order. Report results after each step.
Step 1: Compress sessions
Read .claude/rules/memory-sessions.md. Summarize all entries older than 30 days into a ## Archive block. Keep the 4 most recent sessions in full. Rewrite the file.
Report: lines before → lines after.
Step 2: Prune decisions
Read .claude/rules/memory-decisions.md. Identify decisions whose tools, files, or patterns no longer exist in the project (check with Glob/Grep). Remove obsolete entries. Flag anything you removed so the user can restore it if needed.
Report: decisions before → decisions after, what was removed.
Step 3: Sync to knowledge graph
Extract 3–5 key project facts from the memory files (active integrations, key constraints, architectural choices). Write each as an entity to the memory MCP graph using mcp__memory__create_entities. This makes them queryable in future sessions without loading the full files.
Report: entities written.
Step 4: Summary
Print a single table: lines saved, decisions pruned, entities synced.
