Claude SDLC Plugin

A Claude Code plugin that automates software development lifecycle (SDLC) workflows with an interactive Storybook-based planning hub.

Generate professional SDLC artifacts with AI-assisted iterative planning.

What It Does

The SDLC plugin scaffolds complete software projects with proper documentation, then guides you through an iterative planning process that validates each stage with you before proceeding.

Commands

Command	Description
/sdlc:init	Scaffold a monorepo with Storybook planning hub, design system, and quality tooling
/sdlc:plan	Interactive planning wizard - generates artifacts in dependency order with validation
/sdlc:implement	TDD implementation from validated planning artifacts with quality gates
/sdlc:update	Sync artifacts with implementation progress from git history
/sdlc:review	Verify implementation matches planning artifacts (API spec, ERD, domain model, acceptance criteria)
/sdlc:qa	Quality assurance - test coverage, test quality, E2E gaps, security scanning
/sdlc:refs	Sync/search local reference repos (curated awesome-* lists) for planning support

What Gets Generated

• Requirements - User stories, acceptance criteria, traceability matrix
• Architecture - System design, ADRs, OpenAPI specs, data models
• UX Design - Personas, user journeys, interactive prototypes
• Quality - Test plans, security reviews, code quality configs
• Project Management - Charter, WBS, risk register, schedules

Installation

Quick Start (Session Only)

claude --plugin-dir "/path/to/claude-sdlc-plugin"

Global Installation

1. Clone the repository:

git clone https://github.com/45ck/claude-sdlc-plugin.git

2. Add to your Claude Code user settings (~/.claude/settings.json):

{
  "enabledPlugins": {
    "sdlc@sdlc-local": true
  },
  "extraKnownMarketplaces": {
    "sdlc-local": {
      "url": "file:///path/to/claude-sdlc-plugin/.claude-plugin/marketplace.json"
    }
  }
}

3. Restart Claude Code - the plugin is now available globally.

Prerequisites

• Claude Code v2.1+
• pnpm - For monorepo workspace management
• Node.js 18+ - For Storybook and build tools
• Git - For version control

Usage

1. Initialize a Project

/sdlc:init my-app

Creates:

my-app/
├── docs/                    # SDLC artifacts
├── packages/
│   ├── planning-hub/        # Storybook site
│   └── ui/                  # Design system
├── pnpm-workspace.yaml
├── package.json
└── ... (quality configs)

2. Start the Planning Hub

cd my-app
pnpm install
pnpm dev:storybook

Opens at http://localhost:6006

3. Plan Your Feature

/sdlc:plan

The wizard walks you through:

1. Kickoff - Project scope and constraints
2. Scenarios - As-is and visionary user scenarios
3. Use Cases - Activity diagrams and workflows
4. Domain Model - Class diagrams and entities
5. Data Model - ERD and database schema
6. API Contract - OpenAPI specification
7. Prototypes - Interactive Storybook components
8. Sign-off - Requirements traceability matrix

Each stage is validated with you before proceeding.

Team Mode (Optional)

/sdlc:plan can run in Solo mode (single agent) or Team mode (parallel specialist subagents + synthesis). The skill will ask which you want at the start.

Typical Team mode workflow:

# (optional) keep local references current
/sdlc:refs

# plan with parallel subagents + synthesis
/sdlc:plan

4. Implement Your Feature

/sdlc:implement

TDD implementation driven by your validated planning artifacts. Generates code with quality gates: tests first, then implementation, then verification against acceptance criteria.

5. Track Implementation

/sdlc:update

Scans git commits and updates artifact status.

6. Verify Design Conformance

/sdlc:review

Checks that code matches planning artifacts: API routes vs OpenAPI spec, database schema vs ERD, TypeScript classes vs domain model, and acceptance criteria traceability.

7. Quality Assurance

/sdlc:qa

Runs quality checks: test coverage against thresholds, test quality assessment, E2E/integration gap analysis, security dependency audit, and static analysis. Generates a quality score (0-100) with fix-forward options.

Specialized Agents

The plugin includes expert subagents for different SDLC disciplines:
