prd-breakdown-execute

Break down a PRD or CRD into self-contained implementation tasks for LLM execution. Use when you have a PRD/CRD file and want to generate executable task files for autonomous implementation.

Incremental PROJECT.md update using git diff. Only re-analyzes changed areas for efficient context maintenance.

Analyze the impact of a proposed change on an existing codebase. Identifies affected files, features, and potential breaking changes.

Deep codebase investigation to generate PROJECT.md context. Analyzes architecture, patterns, features, APIs, and schemas.

Orchestrates Change Request Document workflow. Manages context, captures changes, analyzes impact, and generates CRD files.

Handles one batch of tasks. Spawns task agents in parallel using git worktrees, waits for completion, and updates state.

Main entry point for hierarchical task execution. Orchestrates layer-by-layer implementation of PRD tasks with parallel worktree execution.

Independent verification agent using Haiku. Runs verification commands from task XML and reports pass/fail with actionable feedback.

Analyze a PRD to extract features, tech stack, and implementation requirements. Called by /breakdown skill during Phase 2.

Generate implementation task files for a specific layer. Called by /breakdown skill during Phase 4.

Plan layer structure and task groupings from PRD analysis. Called by /breakdown skill during Phase 3.

Review generated tasks for quality and completeness. Called by /breakdown skill after task generation.

Handles one layer of task execution. Groups ready tasks into batches, spawns batch agents, and processes merge queue after each batch.

Merges completed task worktree to main branch. Handles sequential merge queue to prevent conflicts.

Implements one task in an isolated git worktree following TDD. Creates commits for implementation and fixes, invokes independent verification.
