compact（compact 搜索）

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

[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

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"

Reference File Categories

8. Plan Detection (Priority Order)

Priority 1: Workflow Session (IMPL_PLAN.md)

// Check for active workflow session
const manifest = await mcp__ccw-tools__session_manager({
  operation: "list",
  location: "active"
});

if (manifest.sessions?.length > 0) {
  const session = manifest.sessions[0];
  const plan = await mcp__ccw-tools__session_manager({
    operation: "read",
    session_id: session.id,
    content_type: "plan"
  });
  sessionAnalysis.sessionId = session.id;
  sessionAnalysis.executionPlan.source = "workflow";
  sessionAnalysis.executionPlan.content = plan.content;
}

Priority 2: TodoWrite (Current Session Todos)

// Extract from conversation - look for TodoWrite tool calls
// Preserve COMPLETE todo list with all details
const todos = extractTodosFromConversation();
if (todos.length > 0) {
  sessionAnalysis.executionPlan.source = "todo";
  // Format todos with full context - preserve status markers
  sessionAnalysis.executionPlan.content = todos.map(t =>
    `- [${t.status === 'completed' ? 'x' : t.status === 'in_progress' ? '>' : ' '}] ${t.content}`
  ).join('\n');
}

Priority 3: User-Stated Plan

// Look for explicit plan statements in user messages:
// - "Here's my plan: 1. ... 2. ... 3. ..."
// - "I want to: first..., then..., finally..."
// - Numbered or bulleted lists describing steps
const userPlan = extractUserStatedPlan();
if (userPlan) {
  sessionAnalysis.executionPlan.source = "user-stated";
  sessionAnalysis.executionPlan.content = userPlan;
}

Priority 4: Inferred Plan

// If no explicit plan, infer from:
// - Task description and breakdown discussion
// - Sequence of actions taken
// - Outstanding work mentioned
const inferredPlan = inferPlanFromDiscussion();
if (inferredPlan) {
  sessionAnalysis.executionPlan.source = "inferred";
  sessionAnalysis.executionPlan.content = inferredPlan;
}

9. Notes

• Timing: Execute at task completion or before context switch
• Frequency: Once per independent task or milestone
• Recovery: New session can immediately continue with full context
• Knowledge Graph: Entity relationships auto-extracted for visualization
• Absolute Paths: Critical for cross-session recovery on different machines
