prd-to-plan
Convert a PRD into a phased implementation plan using vertical-slice tracer bullets.
- Breaks down product requirements into thin, end-to-end slices that cut through all integration layers (schema, API, UI, tests) rather than horizontal layers
- Identifies and documents durable architectural decisions upfront (routes, schema, data models, auth boundaries) so all phases reference consistent foundations
- Outputs a structured Markdown plan file in
./plans/with phases, user story mappings, and acceptance criteria ready for team handoff - Iterates with you on slice granularity before finalizing, ensuring phases are neither too coarse nor too fine
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

grill-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".
124.5Kimprove-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.
91.4Ktdd
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.
89.9Kgrill-with-docs
Grilling session that challenges your plan against the existing domain model, sharpens terminology, and updates documentation (CONTEXT.md, ADRs) inline as decisions crystallise. Use when user wants to stress-test a plan against their project's language and documented decisions.
73.0Kto-prd
Turn the current conversation context into a PRD and publish it to the project issue tracker. Use when user wants to create a PRD from the current context.
72.8Kto-issues
Break a plan, spec, or PRD into independently-grabbable issues on the project issue tracker using tracer-bullet vertical slices. Use when user wants to convert a plan into issues, create implementation tickets, or break down work into issues.
