# AGENTS.md

## Scope

Build and maintain Phast as a deliberately small Python + Prefab + MCP application platform.

## Product model

- `my.phast.app` is the owner control plane.
- Each `app.phast.app` is independently useful and independently connectable.
- `/` is the human Prefab UI by default.
- `/mcp` is the agent interface by default.
- A Prephab is a cloneable Python + Prefab + MCP application shape.

## Working rules

- Prefer boring, explicit Python over framework sprawl.
- Keep one source of truth for app state and capabilities.
- Do not fake auth or security; mark seams explicitly.
- No delete path until it is deliberately designed.
- Commit small coherent changes to `main` and leave the system simpler.
