+# Rhai Engine Worker UI
+
+A Yew-based WASM interface to monitor Rhai workers.
+
+## Prerequisites
+
+- Rust: Install from [rust-lang.org](https://www.rust-lang.org/tools/install)
+- Trunk: Install with `cargo install trunk`
+- A backend service providing the necessary API endpoints (see below).
+
+## Backend API Requirements
+
+This UI expects a backend service to be running that can provide data from Redis. The UI will make requests to the following (example) endpoints:
+
+- `GET /api/worker/{worker_name}/tasks_and_stats`: Returns initial `WorkerData` including a list of `TaskSummary` and initial `QueueStats`.
+  - `WorkerData`: `{ "queue_stats": { "current_size": u32, "color_code": "string" }, "tasks": [TaskSummary] }`
+  - `TaskSummary`: `{ "hash": "string", "created_at": i64, "status": "string" }`
+- `GET /api/worker/{worker_name}/queue_stats`: Returns current `QueueStats` for polling.
+  - `QueueStats`: `{ "current_size": u32, "color_code": "string" }`
+- `GET /api/task/{task_hash}`: Returns `TaskDetails`.
+  - `TaskDetails`: `{ "hash": "string", "created_at": i64, "status": "string", "script_content": "string", "result": "optional_string", "error": "optional_string" }`
+
+**Note:** The API endpoints are currently hardcoded with relative paths (e.g., `/api/...`). This assumes the backend API is served from the same host and port as the Trunk development server, or that a proxy is configured.
+
+## Development
+
+1.  Navigate to the `rhai_engine_ui` directory:
+    ```bash
+    cd /Users/timurgordon/code/git.ourworld.tf/herocode/rhailib/rhai_engine_ui/
+    ```
+2.  Run the development server:
+    ```bash
+    trunk serve --port 8081
+    ```
+3.  Open your browser to `http://127.0.0.1:8081`.
+
+## Building for Release
+
+```bash
+trunk build --release
+```
+This will output static files to the `dist` directory.
