Memory Compact Command (/memory:compact)

1. Overview

The memory:compact command compresses current session working memory into structured text optimized for session recovery, extracts critical information, and saves it to persistent storage via MCP core_memory tool.

Core Philosophy:

• Session Recovery First: Capture everything needed to resume work seamlessly
• Minimize Re-exploration: Include file paths, decisions, and state to avoid redundant analysis
• Preserve Train of Thought: Keep notes and hypotheses for complex debugging
• Actionable State: Record last action result and known issues

2. Parameters

• --description: Custom session description (optional)
  • Example: "completed core-memory module"
  • Example: "debugging JWT refresh - suspected memory leak"
• --tags: Comma-separated tags for categorization (optional)
• --force: Skip confirmation, save directly

3. Structured Output Format

## Session ID
[WFS-ID if workflow session active, otherwise (none)]

## Project Root
[Absolute path to project root, e.g., D:\Claude_dms3]

## Objective
[High-level goal - the "North Star" of this session]

## Execution Plan
[CRITICAL: Embed the LATEST plan in its COMPLETE and DETAILED form]

### Source: [workflow | todo | user-stated | inferred]

4. Field Definitions

Field	Purpose	Recovery Value
Session ID	Workflow session identifier (WFS-*)	Links memory to specific stateful task execution
Project Root	Absolute path to project directory	Enables correct path resolution in new sessions
Objective	Ultimate goal of the session	Prevents losing track of broader feature
Execution Plan	Complete plan from any source (verbatim)	Preserves full planning context, avoids re-planning
Working Files	Actively modified files (absolute paths)	Immediately identifies where work was happening
Reference Files	Read-only context files (absolute paths)	Eliminates re-exploration for critical context
Last Action	Final tool output/status	Immediate state awareness (success/failure)
Decisions	Architectural choices + reasoning	Prevents re-litigating settled decisions
Constraints	User-imposed limitations	Maintains personalized coding style
Dependencies	Package/environment changes	Prevents missing dependency errors
Known Issues	Deferred bugs/edge cases	Ensures issues aren't forgotten
Changes Made	Completed modifications	Clear record of what was done
Pending	Next steps	Immediate action items
Notes	Hypotheses, debugging trails	Preserves "train of thought"

5. Execution Flow

Step 1: Analyze Current Session

Extract the following from conversation history:

const sessionAnalysis = {
  sessionId: "",       // WFS-* if workflow session active, null otherwise
  projectRoot: "",     // Absolute path: D:\Claude_dms3
  objective: "",       // High-level goal (1-2 sentences)
  executionPlan: {
    source: "workflow" | "todo" | "user-stated" | "inferred",
    content: ""        // Full plan content - ALWAYS preserve COMPLETE and DETAILED form
  },
  workingFiles: [],    // {absolutePath, role} - modified files
  referenceFiles: [],  // {absolutePath, role} - read-only context files
  lastAction: "",      // Last significant action + result
  decisions: [],       // {decision, reasoning}
  constraints: [],     // User-specified limitations
  dependencies: [],    // Added/changed packages
  knownIssues: [],     // Deferred bugs
  changesMade: [],     // Completed modifications
  pending: [],         // Next steps
  notes: ""            // Unstructured thoughts
}

Step 2: Generate Structured Text

// Helper: Generate execution plan section
const generateExecutionPlan = (plan) => {
  const sourceLabels = {
    'workflow': 'workflow (IMPL_PLAN.md)',
    'todo': 'todo (TodoWrite)',
    'user-stated': 'user-stated',
    'inferred': 'inferred'
  };

  // CRITICAL: Preserve complete plan content verbatim - DO NOT summarize
  return `### Source: ${sourceLabels[plan.source] || plan.source}

<details>
<summary>Full Execution Plan (Click to expand)</summary>

${plan.content}

</details>`;
};

const structuredText = `## Session ID
${sessionAnalysis.sessionId || '(none)'}

## Project Root
${sessionAnalysis.projectRoot}

## Objective
${sessionAnalysis.objective}

## Execution Plan
${generateExecutionPlan(sessionAnalysis.executionPlan)}

## Working Files (Modified)
${sessionAnalysis.workingFiles.map(f => `- ${f.absolutePath} (role: ${f.role})`).join('\n') || '(none)'}

## Reference Files (Read-Only)
${sessionAnalysis.referenceFiles.map(f => `- ${f.absolutePath} (role: ${f.role})`).join('\n') || '(none)'}

## Last Action
${sessionAnalysis.lastAction}

## Decisions
${sessionAnalysis.decisions.map(d => `- ${d.decision}: ${d.reasoning}`).join('\n') || '(none)'}

## Constraints
${sessionAnalysis.constraints.map(c => `- ${c}`).join('\n') || '(none)'}

## Dependencies
${sessionAnalysis.dependencies.map(d => `- ${d}`).join('\n') || '(none)'}

## Known Issues
${sessionAnalysis.knownIssues.map(i => `- ${i}`).join('\n') || '(none)'}

## Changes Made
${sessionAnalysis.changesMade.map(c => `- ${c}`).join('\n') || '(none)'}

## Pending
${sessionAnalysis.pending.length > 0
  ? sessionAnalysis.pending.map(p => `- ${p}`).join('\n')
  : '(none)'}

## Notes
${sessionAnalysis.notes || '(none)'}`

Step 3: Import to Core Memory via MCP

Use the MCP core_memory tool to save the structured text:

mcp__ccw-tools__core_memory({
  operation: "import",
  text: structuredText
})

Or via CLI (pipe structured text to import):

# Write structured text to temp file, then import
echo "$structuredText" | ccw core-memory import

# Or from a file
ccw core-memory import --file /path/to/session-memory.md

Response Format:

{
  "operation": "import",
  "id": "CMEM-YYYYMMDD-HHMMSS",
  "message": "Created memory: CMEM-YYYYMMDD-HHMMSS"
}

Step 4: Report Recovery ID

After successful import, clearly display the Recovery ID to the user:

╔════════════════════════════════════════════════════════════════════════════╗
║  ✓ Session Memory Saved                                                    ║
║                                                                            ║
║  Recovery ID: CMEM-YYYYMMDD-HHMMSS                                         ║
║                                                                            ║
║  To restore: "Please import memory <ID>"                                   ║
║  (MCP: core_memory export | CLI: ccw core-memory export --id <ID>)         ║
╚════════════════════════════════════════════════════════════════════════════╝

6. Quality Checklist

Before generating:

• Session ID captured if workflow session active (WFS-*)
• Project Root is absolute path (e.g., D:\Claude_dms3)
• Objective clearly states the "North Star" goal
• Execution Plan: COMPLETE plan preserved VERBATIM (no summarization)
• Plan Source: Clearly identified (workflow | todo | user-stated | inferred)
• Plan Details: ALL phases, tasks, file paths, dependencies, status markers included
• All file paths are ABSOLUTE (not relative)
• Working Files: 3-8 modified files with roles
• Reference Files: Key context files (CLAUDE.md, types, configs)
• Last Action captures final state (success/failure)
• Decisions include reasoning, not just choices
• Known Issues separates deferred from forgotten bugs
• Notes preserve debugging hypotheses if any

7. Path Resolution Rules

Project Root Detection

1. Check current working directory from environment
2. Look for project markers: .git/, package.json, .claude/
3. Use the topmost directory containing these markers

Absolute Path Conversion

// Convert relative to absolute
const toAbsolutePath = (relativePath, projectRoot) => {
  if (path.isAbsolute(relativePath)) return relativePath;
  return path.join(projectRoot, relativePath);
};

// Example: "src/api/auth.ts" → "D:\Claude_dms3\src\api\auth.ts"
