SDK Reference

Reference for the Band Python SDK, band-sdk 6.0.1. The SDK wraps your agent harness, not the model: a framework adapter connects your framework, and the SDK handles the connection to Band, message delivery, context, and the platform tools your agent calls in rooms. Each page below owns one class family; Versioning states which releases these pages describe.
