 ### React Component Methodology

 - Shared React UI belongs in `sdks/react` only when it is reusable outside the Inspector.
+- If the same UI pattern is shared between the Sandbox Agent Inspector and Foundry, prefer extracting it into `sdks/react` instead of maintaining parallel implementations.
 - Keep shared components unstyled by default: behavior in the package, styling in the consumer via `className`, slot-level `classNames`, render overrides, and `data-*` hooks.
 - Prefer extracting reusable pieces such as transcript, composer, and conversation surfaces. Keep Inspector-specific shells such as session selection, session headers, and control-plane actions in `frontend/packages/inspector/`.
- Keep `docs/react-components.mdx` aligned with the exported surface in `sdks/react/src/index.ts`.
+- Document all shared React components in `docs/react-components.mdx`, and keep that page aligned with the exported surface in `sdks/react/src/index.ts`.

 ```

+Useful `ChatComposer` props:
+
+- `className` and `classNames` for external styling
+- `inputRef` to manage focus or autoresize from the consumer
+- `textareaProps` for lower-level textarea behavior
+- `allowEmptySubmit` when the submit action is valid without draft text, such as a stop button
+
 Use `transcriptProps` and `composerProps` when you want the shared composition but still need custom rendering or behavior. Use `transcriptClassNames` and `composerClassNames` when you want styling hooks for each subcomponent.

 - GUI state should update in realtime (no manual refresh buttons). Prefer RivetKit push reactivity and actor-driven events; do not add polling/refetch for normal product flows.
 - Keep the mock workbench types and mock client in `packages/shared` + `packages/client` up to date with the frontend contract. The mock is the UI testing reference implementation while backend functionality catches up.
 - Keep frontend route/state coverage current in code and tests; there is no separate page-inventory doc to maintain.
+- If Foundry uses a shared component from `@sandbox-agent/react`, make changes in `sdks/react` instead of copying or forking that component into Foundry.
+- When changing shared React components in `sdks/react` for Foundry, verify they still work in the Sandbox Agent Inspector before finishing.
 - When making UI changes, verify the live flow with `agent-browser`, take screenshots of the updated UI, and offer to open those screenshots in Preview when you finish.
 - When asked for screenshots, capture all relevant affected screens and modal states, not just a single viewport. Include empty, populated, success, and blocked/error states when they are part of the changed flow.
 - If a screenshot catches a transition frame, blank modal, or otherwise misleading state, retake it before reporting it.
