AI Summary: Add an `llms.txt` file to the FastStream project's documentation, following the format specified by llmstxthub.com. This file will improve discoverability by LLMs and should be based on the existing `navigation_template.txt` file.

Python
#asyncapi#asyncio#distributed-systems#faststream#kafka#nats#python#rabbitmq#redis#stream-processing

AI Summary: The task involves writing mypy type checking tests for the public API of the FastStream Python framework, specifically focusing on the return types of various methods related to publishing and subscribing to messages across different message brokers (Kafka, RabbitMQ, NATS, Redis). Tests should be added to the `tests/mypy` directory of the 0.6 branch and extended to include the Confluent broker.

Python
#asyncapi#asyncio#distributed-systems#faststream#kafka#nats#python#rabbitmq#redis#stream-processing

AI Summary: The task is to fix a bug in the FastStream Python framework where the `prefix` argument in `broker.include_router()` does not correctly apply to publishers. This involves modifying the `publisher` code to include the prefix in the topic name, similar to how it's already handled for subscribers, and adding a corresponding test case to ensure the fix works as expected.

FastStream is a powerful and easy-to-use asynchronous Python framework for building asynchronous services interacting with event streams such as Apache Kafka, RabbitMQ, NATS and Redis.

Python
#asyncapi#asyncio#distributed-systems#faststream#kafka#nats#python#rabbitmq#redis#stream-processing

AI Summary: The task is to enhance the FastStream Python framework's `broker.publisher` functionality. Currently, users must specify the subject string twice: once when defining the publisher and again when publishing a message. The improvement should allow the subject string to be automatically formatted using provided arguments, eliminating redundancy and improving developer experience. This could involve either automatically formatting the subject string based on the arguments passed to `publish` or allowing the subject to be defined as a format string with placeholders.

Python
#asyncapi#asyncio#distributed-systems#faststream#kafka#nats#python#rabbitmq#redis#stream-processing

AI Summary: Enhance the RabbitMQ publisher in the FastStream framework to allow users to explicitly specify both the reply queue and the exchange when publishing messages. This involves modifying the `publish` method to handle a new `reply_to` format (e.g., 'queue-name[delimeter]exchange-name') while maintaining backward compatibility with the existing queue-only format.
