- Kicks off a new feature by finding the next incomplete phase in specs/roadmap.md, creating a git branch, interviewing the user about scope/decisions/context, and writing a dated spec directory under specs/ containing plan.md, requirements.md, and validation.md. Trigger when the user says "feature spec", "next phase", "start the next feature", or invokes /feature-spec.
# Feature Spec
## Workflow
### 1. Find the next phase
Read `specs/roadmap.md`. The next phase is the first section whose items are all `[ ]`. Note its name to derive the branch and directory name.
### 2. Create the branch
```
git checkout -b phase-N-<kebab-name>
```
### 3. Interview the user — BEFORE writing any files
Use `AskUserQuestion` with exactly **3 questions in one call**:
| Header | Question focus |
|--------|---------------|
| **Scope** | What the feature collects, exposes, or does — fields, behaviour, data shape |
| **Decisions** | Key implementation choices — storage, visibility, validation, UX pattern |
| **Context** | Tone, constraints, or anything shaping the spec — copy style, stack limits, open questions |
Do **not** write any files until the user has answered all three questions.
### 4. Read guidance files
Read `specs/mission.md` and `specs/tech-stack.md` before drafting.
### 5. Create the spec directory
Name: `specs/YYYY-MM-DD-<feature-name>/` using today's date.
#### `requirements.md`
- Scope section: what is and is not included; field/data table if applicable
- Decisions section: choices made and why (draw from user answers)
- Context section: tone rules, stack pointers, existing patterns to follow
#### `plan.md`
- Numbered task groups appropriate to the feature (for example: Data → Components → Page & Route → Navigation → Tests)
- Each group has numbered sub-tasks; groups should be independently implementable
#### `validation.md`
- Automated: project test and typecheck commands pass; specific assertions required
- Manual: walkthrough, behaviour, edge cases
- Tone check if the feature has user-facing copy
- Definition of done
## Constraints
- Respect the existing tech stack defined in `specs/tech-stack.md` — no new dependencies without user approval
- Follow existing conventions and patterns already established in the codebase
- Keep feature scope focused and independently shippable
