Motivation & Context

I maintain the Donkey Development Kit (DDK), so I'm affiliated with the project this row lists. DDK is an open-source Python SDK that puts agents under MuleSoft Agent Fabric governance: model calls go through an LLM proxy on MuleSoft Omni Gateway, which enforces policies such as PII detection, content safety and token budgets. This PR adds DDK's Agent Framework integration to the Middleware section of the Python catalog.

The integration is published for the Python SDK. donkey-kit 0.2.0 is on PyPI (pip install "donkey-kit[agent-framework]", pypi.org/project/donkey-kit), from a public Apache-2.0 repository at https://github.com/Donkey-Development-Kit/donkey-development-kit. The Agent Framework part works like this:

• policy_middleware() returns a @chat_middleware for Agent(..., middleware=[...]). Both OpenAI chat clients wrap an openai error in a ChatClientException; the middleware sees through that wrapper and raises DDK's typed refusal instead (for example PIIDetected or TokenBudgetExceeded), so the run ends with a specific exception carrying the gateway's correlation id. The original exception is kept on .framework_error. Streaming runs are covered: the conversion is attached to each pull of the response stream.
• chat_client() returns an OpenAIChatClient bound to the proxy, and per-call gateway data (served model, token usage) is readable after each call.

The row is listed for the middleware, not for the OpenAI-compatible client, since the catalog excludes plain OpenAI-compatible endpoints. The row links to DDK's Agent Framework docs page, and issues go to https://github.com/Donkey-Development-Kit/donkey-development-kit/issues/new/choose.

Description & Review Guide

• What are the major changes? One row in the Middleware section of python/samples/community-projects.md, in alphabetical order between BotsRated and Tracekit.
• What is the impact of these changes? Documentation only.
• What do you want reviewers to focus on? The wording of the row. I'm happy to change it or move it.
