Memory Defrag

Reorganize memory files for clarity, efficiency, and relevance. Like filesystem defragmentation but for knowledge.

When to Run

• Periodic: Weekly or biweekly via cron (recommended)
• On demand: User asks to clean up, reorganize, or defrag memory
• Threshold: When MEMORY.md exceeds ~500 lines or daily notes accumulate without consolidation

Process

1. Audit Current State

Inventory all memory files:

MEMORY.md           — long-term memory
memory/             — daily notes, tasks, topical files
memory/tasks/       — active and completed tasks

For each file, note: line count, last modified, topic coverage, staleness.

2. Identify Problems

Look for these common issues:

3. Plan Changes

Before making edits, write a brief plan:

## Defrag Plan
- [ ] Split MEMORY.md "Key People" section → memory/people.md
- [ ] Remove completed tasks older than 30 days from memory/tasks/
- [ ] Merge memory/bm-marketing-ideas.md into memory/competitive/
- [ ] Update stale project status entries in MEMORY.md

4. Execute

Apply changes one at a time:

• Split: Extract sections from large files into focused topical files
• Merge: Combine related small files into coherent documents
• Prune: Remove information that is no longer relevant or accurate
• Restructure: Move files to appropriate directories, rename for clarity
• Update: Fix outdated facts, dates, statuses

5. Verify & Log

After changes:

• Verify no information was lost (compare before/after)
• Update any cross-references between files
• Log what was done in today's daily note:

## Memory Defrag (HH:MM)
- Files reviewed: N
- Split: [list]
- Merged: [list]
- Pruned: [list]
- Net result: X files, Y total lines (was Z lines)

Guidelines

• Preserve raw daily notes. Don't delete or modify memory/YYYY-MM-DD.md files — they're the audit trail.
• Target 15-25 focused files. Too few means bloated files; too many means fragmentation. Aim for the sweet spot.
• File names should be scannable. Use descriptive names: people.md, project-status.md, competitive-landscape.md — not notes-2.md.
• Don't over-organize. One level of directories is usually enough. memory/tasks/ and memory/competitive/ are fine; memory/work/projects/active/basic-memory/notes/ is not.
• Completed tasks: Tasks with status: done older than 14 days can be removed. Their insights should already be in MEMORY.md via reflection.
• Ask before destructive changes. If uncertain whether information is still relevant, keep it with a (review needed) tag rather than deleting.
