Agently

Agently 4 is a Python framework for building GenAI applications, installed with `pip install -U agently` and used with `from agently import Agently`. Its stated aim is to give GenAI application engineers the best developer experience by pulling LLM uncertainty back inside an engineering boundary. The README abstracts away varying model parameters, output formatting and the communication between engineering modules and GenAI logic, while leaving business logic to you. Its main idea is contract-first structured output: define a schema with `output()`, enforce critical fields with `ensure_keys` (including wildcard paths for list items) and let the framework parse and repair the result, without relying on provider-specific JSON-schema switches.

Models are configured through `OpenAICompatible` settings (base URL, model, auth), so local, hosted and proxy providers share one interface, with options such as `full_url` and custom auth headers. The README also covers tool planning with traceability, retries for missing fields and a path from demo to production, with examples under `examples/step_by_step/` including an auto-loop FastAPI service (SSE, WebSocket, POST, Docker-ready). Version 3 code lives on the `v3-final` branch. It is Apache-2.0 licensed with a docs site and English and Chinese introductions.
