Done! I've written a haiku about autumn to `./output/haiku.md` with:

- **Perfect 5-7-5 structure** — each line carefully counted
- **Seasonal reference (kigo)** — "autumn leaves" grounds it in the season
- **Juxtaposition & insight** — the contrast between present decay and future renewal, finding hope in emptiness
- **Wabi-sabi aesthetics** — beauty discovered in transience and impermanence

The haiku uses concrete, economic language and creates a moment of reflection on the cyclical nature of seasons.
