fix(codex): accept Codex 0.150 multi-agent events

[t3dotgg]

Codex 0.150 added multi-agent values that our pinned app-server schema does not accept. A persisted subAgentActivity with kind: "completed" blocks thread/resume, while matching live events and new collaboration tool values get dropped during decoding.

This adds the 0.150 multi-agent enum values to every generated response namespace and keeps the compatibility definitions in the generator. It avoids a full protocol refresh, which would pull unrelated changes and can break older Codex releases. This complements #8342, which makes thread opening tolerant of future history drift but deliberately leaves live event decoding unchanged.

Tests:

• vp test run packages/effect-codex-app-server/src/schema.test.ts packages/effect-codex-app-server/src/client.test.ts packages/effect-codex-app-server/src/protocol.test.ts
• vp run --filter effect-codex-app-server typecheck
• Isolated provider probe with Codex 0.150.0 and an empty temporary CODEX_HOME

Made with GPT-5.6 Sol through the Codex harness in T3 Code.

Note

Medium Risk
Changes protocol decoding across many generated schemas; incorrect overrides could accept invalid payloads or mask upstream schema drift until the next full refresh.

Overview
Codex 0.150 emits multi-agent collaboration enums that the pinned protocol schema still rejects, which can break thread/resume on persisted history and drop live collabAgentToolCall / subAgentActivity events during decode.

This PR adds a Codex0150DefinitionSchemas override in generate.ts so generation substitutes wider enums for CollabAgentTool, CollabAgentToolCallStatus, and SubAgentActivityKind before the usual rewrite pipeline. Regenerated schema.gen.ts carries those values through every response namespace (extra tools sendMessage, followupTask, interruptAgent, listAgents; status interrupted; activity kind completed).

schema.test.ts asserts the generated Effect schemas accept the new literals and a sample V2ThreadResumeResponse with followupTask / interrupted, without a full protocol refresh.

Note

Add Codex 0.150 multi-agent event values to schema generation

• Introduces Codex0150DefinitionSchemas in generate.ts to override parsed definitions for CollabAgentTool, CollabAgentToolCallStatus, and SubAgentActivityKind with hard-coded enum schemas.
• The generateFiles generator substitutes these definitions before normalization and reference rewriting, producing updated generated code in schema.gen.ts.
• New enum members: sendMessage, followupTask, interruptAgent, listAgents for CollabAgentTool; interrupted for CollabAgentToolCallStatus; completed for SubAgentActivityKind.
• Adds a test in schema.test.ts validating the new values across affected schemas and a V2ThreadResumeResponse instance.

Codex 0.150 added multi-agent values that our pinned app-server schema does not accept. A persisted subAgentActivity with kind: "completed" blocks thread/resume, while matching live events and new collaboration tool values get dropped during decoding.

This adds the 0.150 multi-agent enum values to every generated response namespace and keeps the compatibility definitions in the generator. It avoids a full protocol refresh, which would pull unrelated changes and can break older Codex releases. This complements #8342, which makes thread opening tolerant of future history drift but deliberately leaves live event decoding unchanged.

Tests:

• vp test run packages/effect-codex-app-server/src/schema.test.ts packages/effect-codex-app-server/src/client.test.ts packages/effect-codex-app-server/src/protocol.test.ts
• vp run --filter effect-codex-app-server typecheck
• Isolated provider probe with Codex 0.150.0 and an empty temporary CODEX_HOME

Made with GPT-5.6 Sol through the Codex harness in T3 Code.

Note

Medium Risk
Changes protocol decoding across many generated schemas; incorrect overrides could accept invalid payloads or mask upstream schema drift until the next full refresh.

Overview
Codex 0.150 emits multi-agent collaboration enums that the pinned protocol schema still rejects, which can break thread/resume on persisted history and drop live collabAgentToolCall / subAgentActivity events during decode.

This PR adds a Codex0150DefinitionSchemas override in generate.ts so generation substitutes wider enums for CollabAgentTool, CollabAgentToolCallStatus, and SubAgentActivityKind before the usual rewrite pipeline. Regenerated schema.gen.ts carries those values through every response namespace (extra tools sendMessage, followupTask, interruptAgent, listAgents; status interrupted; activity kind completed).

schema.test.ts asserts the generated Effect schemas accept the new literals and a sample V2ThreadResumeResponse with followupTask / interrupted, without a full protocol refresh.

Note

Add Codex 0.150 multi-agent event values to schema generation

• Introduces Codex0150DefinitionSchemas in generate.ts to override parsed definitions for CollabAgentTool, CollabAgentToolCallStatus, and SubAgentActivityKind with hard-coded enum schemas.
• The generateFiles generator substitutes these definitions before normalization and reference rewriting, producing updated generated code in schema.gen.ts.
• New enum members: sendMessage, followupTask, interruptAgent, listAgents for CollabAgentTool; interrupted for CollabAgentToolCallStatus; completed for SubAgentActivityKind.
• Adds a test in schema.test.ts validating the new values across affected schemas and a V2ThreadResumeResponse instance.

Approvability

Verdict: Approved at 7be1453

Macroscope's review found this PR approvable — This is a narrow Codex 0.150 compatibility fix that adds new multi-agent enum values to existing generated schemas without changing workflows or prior accepted values. The generated changes are mechanical and the new behavior is covered by focused protocol tests.

Notes:

• No code objects were reviewed. Approvability was decided on eligibility alone.
