CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

BMad Method is an AI-driven agile development framework built on BMad Core (Collaboration Optimized Reflection Engine). It provides specialized AI agents and guided workflows for software development lifecycle management.

Key Modules:

Core (src/core/) - Universal framework with shared agents, tasks, and workflows
BMM (src/bmm/) - BMad Method for agile software development (flagship module)

Common Commands

# Run all tests (schemas, installation, validation, lint, markdown lint, format check)
npm test

# Run specific test suites
npm run test:schemas          # Agent YAML schema validation tests
npm run test:install          # Installation component tests
npm run validate:schemas      # Validate all *.agent.yaml files against schema

# Code quality
npm run lint                  # ESLint with YAML support
npm run lint:fix              # Auto-fix linting issues
npm run lint:md               # Markdown linting
npm run format:check          # Check Prettier formatting
npm run format:fix            # Auto-fix formatting

# Test coverage
npm run test:coverage         # Generate coverage report with c8

# CLI integration tests
./test/test-cli-integration.sh

Architecture

Module Structure

Each module in src/ follows this pattern:

module/
├── module.yaml           # Module configuration and installer prompts
├── agents/               # Agent definitions (*.agent.yaml)
├── workflows/            # Workflow definitions with workflow.yaml files
├── data/                 # Data files used by workflows
├── teams/                # Team configurations (agent groupings)
└── _module-installer/    # Module-specific installation logic

Agent YAML Schema

Agent files (*.agent.yaml) are validated by tools/schema/agent.js using Zod. Key rules:

Required fields: id, name, title, icon, persona, menu
Module agents must have module field matching their path (e.g., bmm for files in src/bmm/agents/)
Menu triggers must be kebab-case or compound format (TS or fuzzy match on tech-spec)
Test fixtures in test/fixtures/agent-schema/ demonstrate valid/invalid patterns

CLI Tools

tools/cli/bmad-cli.js - Main CLI entry point
tools/bmad-npx-wrapper.js - NPX wrapper (npx bmad-method install)
tools/validate-agent-schema.js - Schema validation CLI wrapper

Workflow System

Workflows are YAML files that guide multi-step processes. Located in module workflows/ directories with:

workflow.yaml - Workflow definition and steps
Supporting data files and templates

Development Notes

Adding New Agents

Create *.agent.yaml in appropriate src/*/agents/ directory
Follow schema in tools/schema/agent.js
Validate with npm run validate:schemas
Add test fixtures if introducing new validation patterns

Modifying Validation

Schema changes go in tools/schema/agent.js. Test fixtures in test/fixtures/agent-schema/ must cover all validation paths (100% coverage required).

PR Guidelines

Submit to main branch for critical fixes only
Keep PRs under 800 lines; split larger changes
Use conventional commits: feat:, fix:, docs:, refactor:, test:, chore:
Validate YAML schemas before committing: npm run validate:schemas
