BMAD-Method Agentic SDLC

Spec-driven, artifact-first software delivery for deep agents.

BMAD-Method Agentic SDLC is a layered software development lifecycle for agentic delivery. It uses Claude Code agents, specialist personas, BMAD skills, commands, and optional deterministic workflows to take software work from idea discovery through PRD, architecture, evaluation, story implementation, QA review, and delivery.

This repository is not primarily a website or app. Generated apps, app/, and sandbox/ are working surfaces and experiments. The core product is the agentic SDLC system.

At A Glance

Layer	Role	Examples
Agent teams	Own lifecycle phases and specialist perspectives	`cs-engineering-lead`, `cs-planning-lead`, `code-reviewer`
Skills	Execute repeatable methods and quality gates	`bmad-prd`, `bmad-dev-story`, `bmad-testarch-nfr`
Commands	Provide user-facing entry points	`/cs:workflow-build`
Artifacts	Carry context across phase boundaries	`prd.md`, `.decision-log.md`, `sprint-status.yaml`
Workflow automation	Makes repeatable multi-agent runs deterministic	`.claude/workflows/*.js`

  D --> NX[Next handoff or release decision]

The lifecycle is intentionally gated. Agents do not just chat toward code; they create artifacts, hand them off, verify them, and keep implementation tied to specs and acceptance criteria.
