# React Canvas Workspace
`agent-html` is a portable Canvas source workspace. It contains durable artifact source, local primitives, styles, public static files, and source dependency metadata. It does not contain runtime install artifacts.
## Read Route
Always:
- `AGENTS.md` for hard operating rules.
- `index/README.md` for generated route summaries.
When authoring an artifact:
- `artifacts/README.md`
- `TASTE.md` for artifact composition and visual judgment.
When using or changing primitives, hooks, helpers, or theme exports:
- `components/README.md` for the component source route.
- `TASTE.md` for component choice and artifact layout judgment when UI composition is part of the task.
- `index/api-surface.md`
- then the closest source file
When touching Canvas classes, tokens, or internal chrome:
- `styles/README.md`
When changing workspace conventions, route files, generated indexes, artifact or data patterns, or copyable examples:
- `GOVERNANCE.md`
## Source Placement
Source placement defaults live in `AGENTS.md`. Use the route above to choose the smallest owner before opening source.
