Story Decomposition

Capabilities

Breaks technical specifications into small, independently implementable stories. Establishes dependency ordering, estimates effort, and creates a dispatching queue for parallel coder execution.

Tool Use Instructions

Use Read to examine the technical specification and existing code
Use Grep/Glob to find existing modules and interfaces that stories will touch
Use Write to generate story definitions
Use Edit to refine stories based on feedback

Process Integration

Used in maestro-orchestrator.js Phase 3 (Story Decomposition)
Used in maestro-development.js (Story Prioritization)
Maps to tasks: maestro-architect-story-decomp, maestro-dev-prioritize
Agent: Architect
Each story should be completable by a single coder in one batch
Outputs feed into parallel coder dispatch
