Define an async run(client) function.\n\n  Workflow:\n  - If unsure about the API, call search_docs first.\n  - Write complete solutions in a single execute call when possible. For large datasets, use API filters to narrow results or paginate within a single execute block.\n  - If execute returns an error, read the error and fix your code rather than retrying the same approach.\n  - Variables do not persist between execute calls. Return or log all data you need.\n  - Individual HTTP requests to the API have a 30-second timeout. If a request times out, try a smaller query or add filters.\n  - Code execution has a total timeout of approximately 5 minutes. If your code times out, simplify it or break it into smaller steps.\n  ';
