What problem does it solve? Coordinating complex software development across specification, architecture, implementation, testing, and review phases is error-prone and slow when done ad hoc. This Skill provides a structured SPARC methodology with 17 specialized agent modes and multi-agent orchestration patterns to systematize the entire development lifecycle. ## Core Features & Use Cases - Phased Development Framework: Guides work through Specification, Architecture, Refinement (TDD), Review, and Completion phases with dedicated modes like researcher, architect, coder, tdd, and reviewer. - Multi-Agent Orchestration: Supports hierarchical, mesh, ring, and star swarm topologies with parallel execution for 2.8-4.4x speed improvements and cross-agent memory sharing. - TDD Workflows: Enforces red-green-refactor cycles with coverage targets of 90%+ across unit, integration, and end-to-end tests. - Use Case: Building a full-stack authentication feature—run the researcher mode to gather JWT best practices, architect mode to design the API, tdd mode to implement with tests, and reviewer mode to validate security, all coordinated through a single orchestrated pipeline. ## Quick Start Ask the AI to run the SPARC pipeline for your feature, for example: use the sparc methodology to design, implement, and test a user authentication module with JWT.
