AI-DLC Plugin for Claude Code

日本語

An implementation of AI-DLC (AI-Driven Development Life Cycle) as a Claude Code plugin. Packages an adaptive software development workflow as skills, agents, and hooks.

Installation

From marketplace (recommended)

Inside Claude Code REPL:

# 1. Register the marketplace
/plugin marketplace add yamatatsu/claude-aidlc

# 2. Install the plugin
/plugin install aidlc@yamatatsu-aidlc

Local development

git clone https://github.com/yamatatsu/claude-aidlc.git
claude --plugin-dir ./claude-aidlc

Usage

Starting a workflow

After enabling the plugin, run in chat:

/aidlc:start

AI-DLC analyzes the workspace, initializes state files, and guides you to the next step.

Basic flow

1. /aidlc:start to begin a project
2. At each stage, AI generates question files (.md) -- you fill in the answers
3. AI generates artifacts -- you review and approve
4. After approval, proceed to the next stage

Use /aidlc:resume to continue after a session break, and /aidlc:status to check progress at any time.

Command details

/aidlc:start — Start new workflow

Analyzes the workspace, auto-detects the project type (greenfield / brownfield), and initializes AI-DLC state management.

• Workspace detection: Determines project type from existing code and build files
• Initialization: Creates aidlc-docs/ directory, aidlc-state.md (state tracking), and audit.md (audit log)
• Next step guidance: Routes to reverse-engineering for brownfield, requirements for greenfield

If aidlc-state.md already exists, suggests /aidlc:resume instead.

/aidlc:resume — Resume from previous session

Resumes a paused workflow from the last completed stage.

• Smart context loading: Loads only artifacts relevant to the current stage to minimize token usage
• Status summary: Shows project type, current phase/stage, and last completed milestone
• Next action options: Offers to continue or review previous artifacts

/aidlc:status — Display progress

Read-only view of current project progress. No files are modified.

• Fast execution (Haiku model, isolated Explore agent)
• Displays progress as checklists for Inception and Construction phases
• Lists all generated artifacts

/aidlc:inception-reverse-engineering — Analyze existing codebase

Comprehensively analyzes a brownfield codebase and generates technical documentation.
