scenario-writer

Installation
SKILL.md

Implement the scenario proposed by the user if that has not been implemented yet. Then invoke the ai-scenario-writer subagent to actually write the test in a separate context. When it finishes please validate its work and launch a new subagent with a new task if the user proposed multiple scenarios (or to correct the work of the last one).

Test Structure

Each test in the tests/ directory should have:

tests/
  {test-name}/
    Reference.svelte  - Reference implementation (known-good solution)
    test.ts          - Vitest test file (imports "./Component.svelte")
    prompt.md        - Prompt for the AI agent
    validator.ts     - Extra validation to verify with static analysis that the code written adhere to Svelte best practices
