What problem does it solve? Turning a high-level PR plan into concrete, step-by-step implementation documentation with complete code is time-consuming and error-prone, often leaving developers with ambiguous instructions or placeholder code. ## Core Features & Use Cases - Plan Parsing: Reads a plan.md file from plans/{feature-name}/ and extracts the feature name, branch, and numbered implementation steps. - One-Time Codebase Research: Runs a single comprehensive research pass covering project structure, coding conventions, build commands, and official library documentation before generating output. - Complete Implementation Files: Produces an implementation.md with copy-paste ready code blocks, markdown checkboxes for every action, verification checklists, and mandatory stop-and-commit points between steps. - Use Case: A developer has an approved plan.md for a new feature and needs a full implementation guide with tested code, exact file paths, and per-step verification that another agent or teammate can execute without making decisions. ## Quick Start Ask the agent to read plans/my-feature/plan.md and generate the complete implementation documentation saved to plans/my-feature/implementation.md.
