Memory Processor

Process changed files and update relevant CLAUDE.md sections following official guidelines.

Guidelines

MANDATORY: All rules below must be followed exactly. Violations produce incorrect CLAUDE.md content.

@../shared/references/guidelines.md

Algorithm

1. Parse context: Read context provided by memory-updater agent:

   • Changed files with categories
   • File content summaries
   • Detected dependencies
   • Git context (commits, diffs)
   • Target CLAUDE.md files

2. Categorize changes: Map files to CLAUDE.md sections using the tables in "Section Names" below. Match changed files to their update triggers.

3. Analyze impact: Determine what needs updating:

   • New build commands added?
   • Architecture changed (new dirs, renamed components)?
   • New coding patterns detected?
   • Dependencies added/removed?

4. Verify and update content: Before modifying documented content, verify accuracy:

   Key distinction - conventions vs patterns:

   • conventions: Explicit rules humans decided (naming, imports, formatting)
   • patterns: Implicit patterns AI detected from recurring code structures

   Removal verification:

   • Read the relevant CLAUDE.md section to get currently documented items
   • For each item that appears missing from changed files:
     • Use Grep to search the codebase for that item
     • Search in relevant directories excluding node_modules, vendor, .git
     • If item exists elsewhere: keep it documented
     • If item is not found anywhere: mark for removal

   Stale command detection:

   • Compare documented commands against commands that actually executed successfully
   • If documented command differs from successful execution, update to match what worked
   • Examples:
     • Documented: python pytest | Actually worked: python -m pytest → Update
     • Documented: npm test | Actually worked: npm run test → Update
     • Documented: pytest tests/ | Actually worked: uv run pytest → Update
   • Source: Successful Bash tool executions from session context or git commit history

   Examples:

   • Pattern: @decorator removed → search grep -r "@decorator" src/
   • Convention: async/await style removed → search for async function or await
   • Architecture: utils/ directory deleted → verify no utils/ references remain
   • Build command: npm run dev removed from package.json → verify script is gone

5. Update CLAUDE.md: Modify relevant sections:

   • Preserve AUTO-MANAGED markers
   • Never touch MANUAL sections
   • Apply content rules (specific, concise, structured)

6. Validate: Ensure updates follow guidelines:

   • No generic instructions added
   • Specific and actionable content
   • Proper markdown formatting

Marker Syntax

CLAUDE.md uses HTML comment markers for selective updates:

<!-- AUTO-MANAGED: section-name -->
Content that will be automatically updated
<!-- END AUTO-MANAGED -->

<!-- MANUAL -->
Content that will never be touched
<!-- END MANUAL -->

Section Names

Root CLAUDE.md Sections

Subtree CLAUDE.md Sections

Token Efficiency

• Keep sections concise - bullet points, not paragraphs
• Use imports (@path/to/file) for detailed specs
• Follow Content Rules above (< 500 lines, stay current)

Output

Return a brief summary:

• "Updated [section names] in [CLAUDE.md path] based on changes to [file names]"
• "Removed [pattern] from [section] - no longer used in codebase"
• "No updates needed - changes do not affect documented sections"
