Changelog

ElevenAgents

• Scoped conversation analysis: Evaluation criteria and data collection items can now be scoped to conversation (full transcript) or agent (only the portion where a specific agent was active). Added scope field to PromptEvaluationCriteria, data_collection_scopes to agent platform settings, and a new scoped array of ScopedAnalysisResult on the conversation analysis response. This is particularly useful for multi-agent workflows where each agent should be evaluated independently.

• Agent test folder management: Tests can now be organized into folders. New endpoints for creating, retrieving, updating, and deleting test folders, plus bulk moving tests between folders.

• Tool and knowledge base overrides in workflows: Agent workflow node overrides now support tool_ids and knowledge_base fields in PromptAgentAPIModelOverrideConfig, allowing workflow nodes to control which tools and knowledge base documents each sub-agent can access.

• Response filter hide_all mode: Added hide_all option to ResponseFilterMode, forcing the system to hide all fields of a tool response from the agent.

• Visited agents in conversation history: The get conversation response now includes a visited_agents array of VisitedAgentRef objects (with agent_id and branch_id), tracking which agents participated in a multi-agent conversation.

• Multimodal message support in hooks: The useConversationControls hook now exposes sendMultimodalMessage, and the MultimodalMessageInput type is exported from @elevenlabs/client, making it easier to send images and other multimodal content during conversations.

Speech to Text

• Audio duration in responses: The convert speech to text response now includes an audio_duration_secs field, providing the total duration of the transcribed audio without requiring client-side calculation.

Voices

• Recording quality and review status: The get voice response now includes recording_quality (enum: studio, good, ok, poor, bad) and labelling_status (enum: in_review, review_complete) fields, providing visibility into voice quality assessment.
