Mega Plan

A project-level orchestration system that sits above hybrid-ralph to manage multiple parallel features as a unified project plan.

Auto-Recovery Protocol (CRITICAL)

At the START of any interaction, perform this check to recover context after compression/truncation:

1. Check if .mega-execution-context.md exists in the project root

2. If YES:

   • Read the file content using Read tool
   • Display: "Detected ongoing mega-plan execution"
   • Show current batch and active worktrees from the file
   • CRITICAL: All feature work MUST happen in worktrees, NOT main branch
   • If unsure of state, suggest: /mega:resume --auto-prd

3. If NO but mega-plan.json exists:

   • Run: uv run python "${CLAUDE_PLUGIN_ROOT}/skills/mega-plan/scripts/mega-context-reminder.py" both
   • This will generate the context file and display current state

This ensures context recovery even after:

• Context compression (AI summarizes old messages)
• Context truncation (old messages deleted)
• New conversation session
• Claude Code restart

Architecture

Level 1: Mega Plan (Project Level)
    └── Level 2: Features (Feature Level) = hybrid:worktree
              └── Level 3: Stories (Story Level) = hybrid internal parallelism

Quick Start

Create a Mega Plan

Generate a mega-plan from your project description:

/mega:plan Build an e-commerce platform with user authentication, product catalog, shopping cart, and order processing

This will:

1. Analyze your project description
2. Break it into features with dependencies
3. Create mega-plan.json, mega-findings.md, .mega-status.json
4. Display the plan for review

Approve and Execute

After reviewing the mega-plan:

/mega:approve

Or with automatic PRD approval for all features:

/mega:approve --auto-prd

This will:

1. Calculate feature batches based on dependencies
2. Create worktrees for Batch 1 features
3. Generate PRDs in each worktree
4. Wait for PRD approvals (or auto-approve with --auto-prd)
5. Execute story batches within each feature
6. Progress to next feature batch when complete

Monitor Progress

/mega:status

Shows:

• Overall project progress percentage
• Feature status by batch
• Story progress within each feature
• Current batch details

Complete and Merge

When all features are complete:

/mega:complete

This will:

1. Verify all features are complete
2. Merge features in dependency order
3. Clean up worktrees and branches
4. Remove mega-plan files

Commands Reference

/mega:plan

Generate a mega-plan for project-level multi-feature orchestration. Breaks a complex project into parallel features with dependencies.

/mega:plan [options] <project description> [design-doc-path]

Parameters:

Parameters are saved to mega-plan.json and propagated to /mega:approve and feature-level /approve commands.

Example:

/mega:plan --flow full --tdd auto Create a blog platform with user accounts, article management, comments, and RSS feeds

/mega:edit

Edit the mega-plan interactively. Add, remove, or modify features.

/mega:edit

/mega:approve

Approve the mega-plan and start feature execution. Creates worktrees and generates PRDs for each feature in batch-by-batch order.

/mega:approve [options]

Parameters:

Approval Modes:

/mega:status

Show detailed status of mega-plan execution including feature progress, story completion, and batch summary.

/mega:status

/mega:complete

Complete the mega-plan by cleaning up planning files. All features should already be merged via /mega:approve.

/mega:complete

mega-plan.json Format

{
  "metadata": {
    "created_at": "2026-01-28T10:00:00Z",
    "version": "1.0.0"
  },
  "goal": "Project goal",
  "description": "Original user description",
  "execution_mode": "auto",
  "target_branch": "main",
  "features": [
    {
      "id": "feature-001",
      "name": "feature-auth",
      "title": "User Authentication",
      "description": "Detailed description for PRD generation",
      "priority": "high",
      "dependencies": [],
      "status": "pending"
    }
  ]
}

Feature Status Flow

pending → prd_generated → approved → in_progress → complete
                                           ↓
                                        failed

Execution Modes

Auto Mode

Features and their story batches execute automatically:

Batch 1 (Features) → PRDs generated → approved → stories execute → complete
         ↓
Batch 2 (Features) → PRDs generated → approved → stories execute → complete
         ↓
All complete → /mega:complete

Manual Mode

Each batch waits for explicit confirmation:

Batch 1 → PRDs generated → [you review] → /approve in each worktree
         ↓
Batch 2 → PRDs generated → [you review] → /approve in each worktree
         ↓
All complete → /mega:complete

Workflows

Complete Workflow

1. /mega:plan "Build e-commerce platform"
   ↓
2. Review generated mega-plan.json
   ↓
3. /mega:edit (if needed) or /mega:approve
   ↓
4. Feature worktrees created (Batch 1)
   ↓
5. PRDs generated in each worktree
   ↓
6. Review and /approve in each worktree (or use --auto-prd)
   ↓
7. Stories execute in parallel
   ↓
8. Monitor with /mega:status
   ↓
9. Batch 2 features start when Batch 1 complete
