Summary
Replaces Kit鈥檚 local OpenAI Responses transport and codec with AgentKit鈥檚 reusable
OpenAIResponsesAdapter. Provider resilience is enabled by default without adding user-facing configuration, while Kit retains its ChatGPT authentication and private endpoint behavior.Uses the released AgentKit packages for shared provider resilience and keeps only
agentkit-acppinned to the rebased ACP v2 PR.Motivation
Kit鈥檚 subscription provider duplicated request encoding, SSE decoding, retries, continuation handling, and response-attempt recovery now provided generically by AgentKit.
Impact
OpenAI subscription sessions retain their long-running retry and timeout policy. OpenRouter and Speakeasy now use AgentKit鈥檚 default resilience policy automatically. The release version advances to 0.1.111.
Technical details
Subscription authentication and migration
Kit retains OAuth login, credential persistence, proactive refresh, rejected-token-aware 401 refresh, and account/login-generation binding. Kit migrates its legacy
openai.subscription.v1continuation metadata before requests enter AgentKit, keeping the compatibility policy consumer-owned.Response-attempt supersession
Kit opts supporting sessions into AgentKit鈥檚 typed response-attempt supersession capability and maps typed supersession events into ACP response replacement behavior.
Dependency boundary
Released AgentKit crates provide the generic resilience and Responses implementations. The ACP crate remains pinned to danielkov/agentkit#13 for the unreleased session-injection API, with its supporting AgentKit crates resolved from their released packages.
