## Prerequisite check

Before routing to any agent, verify `/init` has been run:
- Check if `spec/PROJECT.md` exists
- If NOT exists → output: "Project not initialized. Run `/init` first to analyze your codebase and set up the spec directory." → **STOP**

## Model selection

Assess task size per `spec/rules/_model-routing.md`:
- If updating an existing spec with minor changes (feature directory already exists, spec.md present) → spawn `spec-writer` with `model: haiku`
- If creating a new feature spec from scratch → spawn `spec-writer` with `model: sonnet`

## Task

Spawn `spec-writer` agent (with assessed model) with the following prompt:

```
Write or update the feature specification based on the following:
