Confirmed the live failure and pushed the fix in 7fde8eb. The captured parent response still used the reserved The fix assigns fixed request-scoped aliases to all three names, rewrites matching tool choices and replayed calls, restores the original identities in JSON/SSE/WebSocket/snapshot paths, and leaves the request unchanged on alias conflicts. It also handles an upstream response that omits the namespace and returns only the temporary tool name. Verification:

🔵 Needs a closer look
It changes core Responses request/response rewriting and continuation caching semantics across JSON/SSE/WS, which is protocol-sensitive despite strong test coverage.
Pull request overview
Adds an opt-in, default-off pipeline to let native ChatGPT MultiAgentV2 collaboration tool calls deliver plaintext message arguments to routed children by rewriting the reserved collaboration namespace + message-tool names on the upstream request boundary, then restoring the original identities in all client-facing response shapes (JSON, SSE, WS, snapshot/continuation).
Changes:
- Introduces
plaintextV2AgentMessages?: booleanconfig option with validation/degradation warnings and a startup warning when explicitly enabled. - Implements request-time aliasing + selective removal of
parameters.properties.message.encrypted: true, and response-time restoration while preservingencrypted_function_args: []and failing closed on conflicts/limits. - Adds comprehensive unit/integration tests (including WS relay coverage) and updates English + zh-cn docs.

with authMode "forward", while preserving existing provider authentication and
HTTPS transport; explicitly exclude API-key providers, arbitrary
OpenAI-compatible endpoints, custom targets, and downstream routed providers.

Requesting changes on exact head e5cf3444c0079cbdfa9a27b107820c6334f68a27. The opt-in/canonical-forward direction is reasonable, but this draft is not ready to merge yet.
Two functional blockers remain:
restorePlaintextV2AgentMessageCalls*returns the original upstream payload after the 10,000-identity work limit is exceeded. The continuation cache correctly skips that response, but the live JSON/SSE/WS client path can still exposecollaboration-optimizeand the fixed internal aliases to Codex. Please make overflow fail closed at every client delivery path (with a regression for bounded JSON and streamed/reframed output), rather than only suppressing persistence.hasAgentMessageToolAliasCatalogConflictchecks fixed aliases only among children of thecollaborationnamespace. A normal top-level tool or a tool under another namespace can already be namedstart_delegated_task,deliver_delegated_message, orcontinue_delegated_task; restoration can then map that unrelated call back tospawn_agent,send_message, orfollowup_task. Scan every declaration/reference scope or restore only a namespace-authenticated alias, and add top-level plus foreign-namespace collision regressions.
Before marking the PR ready, also resolve the two current documentation contract errors: fresh configuration is unset/disabled rather than explicit false, and this rewrite is limited to the canonical openai authMode: "forward" ChatGPT path—not API-key, custom-compatible, or routed-provider destinations. Keep the English and Chinese pages synchronized.
The PR is also 29 commits behind its recorded base and its exact-head CI has failures, so please update it onto current dev and rerun the complete cross-platform suite after these fixes. I will re-review the new exact head.

Closing this PR as part of the maintainer backlog pass, with the issue (#2495) left open. Thank you for the work here — the alias/restore design, the fail-closed 10k identity cap, and the WS/SSE/snapshot coverage are careful, and the core-lab boundary and Why it is not being landed in this batch:
Reopen path: a maintainer-owned rebase onto current |
Summary
plaintextV2AgentMessagesconfiguration field. A fresh config leaves the field unset, and the path runs only when the operator explicitly sets it totrue.adapter: "openai-responses",authMode: "forward", andhttps://chatgpt.com/backend-api/codex.collaborationcatalog, replace the namespace and the reservedspawn_agent,send_message, andfollowup_taskfunction names with fixed request-scoped aliases. Remove onlyparameters.properties.message.encrypted: truefrom those three declarations.additional_tools, in tool-search results, in tool choices, or in replay history.response.failed, private aliases are not sent to Codex, and the refused response is not retained forprevious_response_id.Addresses #2495.
Scope and compatibility
OpenAI API-key providers, custom OpenAI-compatible gateways, routes whose final destination is another provider, Anthropic-protocol callers, V1 tools, custom collaboration namespaces, and disabled configurations remain unchanged. The option adds no recovery request and does not decrypt an existing task. HTTPS still protects transport, but the rewritten task text may remain in Codex history, OpenCodex response state or debug files, and the selected child provider.
The implementation was checked against Codex CLI
0.149.1. That version retains the six-tool default collaboration catalog, the three encrypted message fields, and theencrypted_function_args: []plaintext receiving rule. These fields do not have a public compatibility promise.Review 5058244495
