# Lifecycle Kit

## Documentation

- [Grow procedural creatures from causes, not catalogs](https://jonbogaty.com/lifecycle-kit/introduction/index.md): A deterministic TypeScript stage stack for chemistry, biological scaling, form, pigment, and 2.5D assembly.
- [Get started](https://jonbogaty.com/lifecycle-kit/get-started/index.md): Install Lifecycle Kit and run a deterministic chemistry-and-metabolism example.
- [Pipeline architecture](https://jonbogaty.com/lifecycle-kit/pipeline/index.md): How Lifecycle Kit's independent stages exchange renderer-neutral data.
- [Determinism and validation](https://jonbogaty.com/lifecycle-kit/determinism/index.md): The package's invariants for reproducible procedural generation.
- [Render a creature](https://jonbogaty.com/lifecycle-kit/rendering/index.md): Turn Lifecycle Kit geometry and palette data into SVG, Pixi, or a custom renderer without losing deterministic draw order.
- [Agentic consumers](https://jonbogaty.com/lifecycle-kit/agentic-consumers/index.md): A narrow, deterministic contract for coding agents and other automated systems that integrate Lifecycle Kit.
- [API reference](https://jonbogaty.com/lifecycle-kit/api-reference/index.md): Generated reference for every supported Lifecycle Kit export.
