Explore a codebase to find architectural improvement opportunities, focusing on deepening shallow modules for better testability. Use when the user wants to improve code structure, reduce coupling, or make modules more testable.
Break a PRD into independently-grabbable GitHub issues linked as native sub-issues using vertical slices. Use when the user has a PRD issue and wants to decompose it into implementable work items.
Create a detailed refactor plan with tiny, independently-verifiable commits via user interview. Use when the user wants to restructure code without changing behavior, or requests a refactoring plan.
Investigate a bug or issue, find its root cause, and create a GitHub issue with a TDD-based fix plan. Use when the user reports a bug, wants to triage a problem, or needs root cause analysis.
Create a product requirements document (PRD) through interactive interview, codebase exploration, and module design. Use when the user wants to plan a new feature, write a PRD, or design a system before implementation.
Write Ralphai plan files for autonomous execution. Use when asked to create a plan, task, or backlog item for Ralphai.
