PRD to Plan
Break a PRD into a phased implementation plan using vertical slices (tracer bullets). Output is a Markdown file in ./plans/.
Process
1. Confirm the PRD is in context
The PRD should already be in the conversation. If it isn't, ask the user to paste it or point you to the file.
2. Explore the codebase
If you have not already explored the codebase, do so to understand the current architecture, existing patterns, and integration layers.
3. Identify durable architectural decisions
Before slicing, identify high-level decisions that are unlikely to change throughout implementation:
- Route structures / URL patterns

improve-codebase-architecture
Find deepening opportunities in a codebase, informed by the domain language in CONTEXT.md and the decisions in docs/adr/. Use when the user wants to improve architecture, find refactoring opportunities, consolidate tightly-coupled modules, or make a codebase more testable and AI-navigable.
11grill-me
Interview the user relentlessly about a plan or design until reaching shared understanding, resolving each branch of the decision tree. Use when user wants to stress-test a plan, get grilled on their design, or mentions "grill me".
11tdd
Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.
11frontend-design
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, artifacts, posters, or applications (examples include websites, landing pages, dashboards, React components, HTML/CSS layouts, or when styling/beautifying any web UI). Generates creative, polished code and UI design that avoids generic AI aesthetics.
11write-a-skill
Create new agent skills with proper structure, progressive disclosure, and bundled resources. Use when user wants to create, write, or build a new skill.
10gitmoji
Write a commit message using gitmoji. Use when writing a git commit, suggesting a commit message, or when asked to gitmoji a message.
