About slice
slice is a roadmap skill for deepening one named area of an existing design. It reuses parent decisions, updates the design section, and stops before generating tasks.
Key features
- 01Focus on one named area
- 02Inspect relevant repository context first
- 03Reuse parent roadmap decisions
- 04Revise and review the design section
- 05Stop before task generation
Use cases
- 01Deepen an area in an existing roadmap
- 02Extend a slice while preserving an existing design
- 03Refine a scoped design after repository recon

Details
From the project READMESlice
Use roadmap to deepen one area inside the canonical design.
A slice is a scoped design view, not a separate planning process.
Workflow
- Load
../roadmap/SKILL.mdand../roadmap/references/roadmap-schema.md. - Read the parent roadmap or legacy design and the named area.
- Run repository recon for that area before asking anything.
- Reuse settled parent decisions. Ask only a newly discovered blocking question; do not restart the interview or exceed Roadmap's five-question planning-round cap.
- Add or revise a subsection under
## 6. Design. - Re-run the ponytail and rubber-duck checks for affected decisions.
- Stop before task generation.
Compatibility
- If the user provides an existing slice file, maintain it and link it from the roadmap rather than forcing a migration.
- For new work, do not create separate slice files by default.
- Preserve unrelated design sections and all consumed-task history.
Rules
- One named area per invocation.
- Smallest end-to-end version that satisfies the parent outcome wins.
- Name concrete paths, symbols, inputs, outputs, and reused patterns.
- Do not invent categories that the area does not need.
- No code, task lists, speculative extension points, or repeated product discovery.
