FORGE

Specification-Driven AI Development Engine for Claude Code

FORGE transforms Claude Code into a powerful iterative development system that autonomously works on complex tasks through formal specifications, structured planning, and completion criteria verification.

Features

• Specification-Driven Development - Formal specs with requirements, criteria, and clarification
• Structured Planning - Break down specs into tasks with dependencies
• Multi-Criteria Completion - Tests, coverage, lint, file checks, custom scripts
• Intelligent Stuck Detection - Automatic recovery with multiple strategies
• Checkpoints & Rollback - Git-based snapshots, never lose progress
• Control Center - Web dashboard for real-time monitoring
• Dark/Light Theme - System preference detection with manual toggle
• Task Queue - Schedule, prioritize, and auto-advance through tasks
• Sync v2 Protocol - Conflict-free sync with optimistic locking
• Task Locking - Exclusive execution with heartbeat renewal
• Intervention System - Pause, abort, retry tasks from Control Center
• Batch Mode - Process entire queue autonomously

Quick Start

1. Clone and Build

git clone https://github.com/devsforge/Forge.git
cd Forge
pnpm install
pnpm build

2. Install Plugin in Claude Code

# Add the marketplace
/plugin marketplace add devsforge/forge

# Install the plugin
/plugin install forge@devsforge

Or for local development, add to ~/.claude/settings.json:

{
  "plugins": [
    "/path/to/Forge/packages/plugin"
  ]
}

The plugin provides:

• Stop Hook - Intercepts exit to check completion criteria
• Commands - All /forge:* slash commands (21 total)

3. Start Control Center

cd /path/to/Forge
pnpm dev:server
# Opens at http://127.0.0.1:3344

Or run directly:

node packages/server/dist/index.js

4. Register Project

/forge:forge-register

This creates .forge.json and registers your project with Control Center.

5. Create a Specification

/forge:forge-spec "Add user authentication with JWT tokens"

This creates a formal specification with:

• Requirements analysis
• Acceptance criteria
• Technical considerations
• Clarifying questions

6. Create Implementation Plan

/forge:forge-plan spec-001

Generates a detailed plan with:

• Architecture decisions
• Task breakdown with dependencies
• Success criteria per task

7. Queue Tasks

/forge:forge-queue --plan plan-001

8. Execute

# Single task mode (interactive)
/forge:forge

# Batch mode (process entire queue autonomously)
/forge:forge-batch

FORGE will:

1. Claim the next task from queue (with exclusive lock)
2. Work iteratively until criteria pass
3. Auto-advance to the next task
4. Repeat until queue is empty
