Memory Optimizer

Optimizes Claude Code memory files through 4 interactive steps.

No context: fork — must run in main conversation to spawn agents.

Phase 0: Load Context

0. Determine memory directory ($MEMORY_DIR):

   CUSTOM_DIR=$(cat .claude/settings.json 2>/dev/null | jq -r '.autoMemoryDirectory // empty')
   if [ -n "$CUSTOM_DIR" ]; then
     MEMORY_DIR="$(git rev-parse --show-toplevel)/$CUSTOM_DIR"
   else
     MEMORY_DIR=~/.claude/projects/<hash>/memory
   fi
   

   Read .claude/settings.json (if exists) → extract autoMemoryDirectory. If set → resolve as <git-root>/<autoMemoryDirectory>. If not set → use legacy ~/.claude/projects/<hash>/memory/ glob pattern.

1. Glob all memory files: $MEMORY_DIR/*.md (or ~/.claude/projects/**/memory/*.md for legacy)

2. Read ~/.claude/CLAUDE.md and project CLAUDE.md (if exists)

3. Glob .claude/rules/*.md — read all project rules

4. Read ~/.claude/rules/*.md — read all global rules

Build context map:

memory_dir: $MEMORY_DIR
memory_files: [paths]
claude_md_sections: [sections]
rules_files: [paths with content]

Step 1: Analysis — Remove Duplicates (Interactive)

Goal: Find memory entries that duplicate content already in CLAUDE.md or rules.

1. Spawn Explore agent to cross-reference all loaded files
2. Identify entries where:
   • Same rule already in CLAUDE.md
   • Same pattern already in a rules file
   • Contradicts CLAUDE.md (CLAUDE.md wins)
3. Show analysis:

   Found X duplicate/redundant entries (Y% of memory):
   | Entry | Memory File | Already In | Action |
   |-------|-------------|------------|--------|
   | "Use grepai first" | MEMORY.md:5 | rules/grepai-first.md | DELETE |
   ...
   

4. AskUserQuestion: "Delete X duplicate entries (Y% of memory)? This is safe — content exists elsewhere."
   • Options: "Yes, delete all" / "Review each" / "Skip this step"
5. Apply deletion using Edit tool if approved

Step 2: Migration — Move to Rules/CLAUDE.md (Interactive)

Goal: Identify remaining memory entries better suited to persistent config files.

Decision tree (per entry):

• Applies to ALL projects + IS a rule/constraint → ~/.claude/rules/
• Applies to THIS project only + IS a rule → .claude/rules/
• IS an architectural decision → project CLAUDE.md
• IS a fact/pattern reusable across sessions → KEEP in memory

1. Show categorization:

   X entries suitable for migration:
   | Entry | Current Location | Target | Reduction |
   |-------|-----------------|--------|-----------|
   | "Always use BD_PLUGIN_ROOT" | MEMORY.md:12 | .claude/rules/brewdoc.md | 15 tokens |
   ...
   Total: X entries → ~Y tokens saved
   

2. AskUserQuestion: "Migrate X entries to rules/CLAUDE.md?"
   • Options: "Yes, migrate all" / "Review each" / "Skip this step"
3. If approved:
   • Create/append to target rule files via Edit
   • Remove migrated entries from memory via Edit
   • If target file doesn't exist, create it

Step 3: Compression (Interactive)

Goal: Compress remaining entries using LLM-efficient formatting.

Compression techniques:

• Prose → table row
• Multiple related entries → single table
• Verbose description → imperative one-liner
• List of examples → pattern + one example

1. Show compression preview:

   Compression opportunities found:
   | Before | After | Savings |
   |--------|-------|---------|
   | "When you need to... always use..." | "Use X for Y" | 8 tokens |
   ...
   Total: ~Y% token reduction (~Z tokens)
   

   Show 2-3 specific before/after samples.
2. AskUserQuestion: "Compress remaining memory? (~Y% reduction)"
   • Options: "Yes, compress all" / "Skip compression"
3. Apply compression via Edit (bottom-up order to preserve line numbers)

Step 4: Validation (Automatic)

Goal: Verify final state and clean orphaned references.

1. Spawn reviewer agent to verify:
   • No broken file path references in memory files
   • No contradictions between memory and CLAUDE.md
   • Memory files are well-formed markdown
2. Clean broken references (Edit tool)
3. Check for orphaned memory files (files in $MEMORY_DIR with no MEMORY.md reference)
4. Report orphaned files and ask to delete

Final Report:

## Memory Optimization Complete

### Summary
| Metric | Before | After | Saved |
|--------|--------|-------|-------|
| Total entries | X | Y | Z |
| Duplicate entries | X | 0 | — |
| Migrated entries | — | — | X |
| Token estimate | ~X | ~Y | ~Z (~P%) |

### Changes Made
- Step 1: Deleted X duplicate entries
- Step 2: Migrated X entries to rules/CLAUDE.md
- Step 3: Compressed X entries (Y% reduction)
- Step 4: Fixed X broken references, removed X orphaned files
