OpenAI rejects 1,200-line community PR for Google's A2A agent protocol (github.com)

A large community contribution — roughly a 1,200-line pull request to the openai-agents-python repository — that attempted to add support for Google’s A2A (agent‑to‑agent) protocol was declined and the PR closed without merge. The GitHub thread shows many unresolved suggestions and UI warnings about suggestions that couldn’t be applied, indicating the patch required substantial changes and could not be merged as submitted. OpenAI maintainers opted not to accept the community implementation, leaving the repository unchanged. The decision matters because A2A aims to standardize inter‑agent messaging and tooling interoperability; acceptance would have made it much easier for OpenAI-based agents to talk to Google‑style agents and vice versa. Rejecting the contribution signals OpenAI’s cautious approach to adopting third‑party agent protocols — likely driven by compatibility, security, maintenance, or licensing concerns — and raises friction for cross‑platform agent ecosystems. Technically, the refusal means developers who want A2A support will need to maintain their own adapters or forks, or push for a revised, maintainer‑approved implementation or formal standardization between platforms.
