Move AsyncAPI schemas from packages/types/schemas/ to schemas/ at repo root, with symlinks from both packages. Move manually maintained types (Role, Mode, Status, Callbacks, etc.) from @elevenlabs/types to @elevenlabs/client, making the types package generated-code-only. This is preparation for event codegen in the client package, which needs direct access to the schemas. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Records the removal of manual types from @elevenlabs/types as a minor bump (pre-v1). Consumers should import these types from @elevenlabs/client instead. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Add `scripts/generate-events.ts` to the client package that reads `agent.asyncapi.yaml` and generates: - `GeneratedEventMap` with typed event callbacks for each wire event - `GeneratedWireType` union of all generated wire type strings - `WIRE_TYPE_TO_EVENT_NAME` / `WIRE_TYPE_TO_PAYLOAD_FIELD` lookup tables - `dispatchGeneratedEvent()` helper for runtime dispatch Internally handled events (audio, agent_response, user_transcript, client_tool_call, ping, error, internal_tentative_agent_response) are excluded — they need custom dispatch logic in BaseConversation.

Codegen emits unused import for payload-less events
Low Severity
The codegen script imports the type name for every event (events.map((e) => e.typeName)), but only references the type in GeneratedEventMap when payloadField is non-null (line 160). For guardrail_triggered, which has payloadField: null, GuardrailTriggered is imported but never used in the generated events.ts. The imports list needs to filter out events with no payload field.

Note
Low Risk
Low risk: changes are build-time tooling plus generated type/lookup tables; runtime impact is limited to adding new source files without modifying existing conversation logic.
Overview
Adds an event codegen pipeline for the JS client:
scripts/generate-events.tsnow readsschemas/agent.asyncapi.yamland generatessrc/generated/events.ts(typedGeneratedEventMap/GeneratedWireTypeplus wire-type lookup tables) andsrc/generated/dispatch.ts(dispatchGeneratedEvent()helper).Wires this into the monorepo build via a new
generate-eventsscript and Turbo task (with declared inputs/outputs), and addsyaml+prettierdev dependencies to support parsing and formatting of generated files.Reviewed by Cursor Bugbot for commit ccc9b90. Bugbot is set up for automated code reviews on this repo. Configure here.
