Update an evaluator

Changed on

Partially update an evaluator. Same field shape as create — see scenarios_create for details.

If you set or edit expected_outcome_prompt: it is evaluated only when the project's Expected Outcome metric is attached to the scenario — check its metrics and attach that metric if missing.

Tip: to add or modify a single condition inside a conditional_actions scenario, fetch the scenario with GET, parse its instructions (the same object as conditional_actions), edit it, and PATCH the full object back as conditional_actions. The server replaces all conditions atomically.

scenario_type'instruction' | 'conditional_actions'

Type of scenario to create:

  • instruction: Standard instruction-based scenario where the instructions field contains plain text
  • conditional_actions: Conditional action-based scenario where the instructions field contains a JSON structure

Default: instruction. Must be sent as conditional_actions when the request includes the conditional_actions field.

  • instruction - Instruction
  • conditional_actions - Conditional Actions
instructionsstring

Scenario Instructions - the format depends on the scenario_type:

For scenario_type="instruction": Provide plain text instructions that describe the scenario behavior. Example: "You are a customer calling to inquire about your order status. Be polite and provide order number 12345 when asked."

For scenario_type="conditional_actions": Use the structured conditional_actions field instead. If you send via instructions, pass a JSON-formatted string with the following structure:

{
  "role": "A friendly customer calling about an appointment",
  "first_message": "Hi, I'd like to check on my upcoming appointment <silence time=\"1.5s\" />",
  "conditions": [
    {"when": "The agent asks for your name", "say": "My name is Sarah Johnson"},
    {"when": "The agent asks for your date of birth", "say": "January first, nineteen ninety"},
    {
      "when": "The agent confirms your identity and provides appointment details",
      "say": "Thank you, that's all I needed <silence time=\"1.0s\" />",
      "then": ["<endcall />"]
    }
  ]
}

Note: When sent via instructions, the value must be a JSON-formatted string (e.g. JSON.stringify(...) / json.dumps(...)). For new integrations, use the structured conditional_actions field below. Responses return instructions in this same shape.

Structure Details:

  • role (string): Personality/role description for the scenario actor

  • first_message (string | object): What the scenario actor says first, always verbatim. Empty means wait for the agent to speak. Use {"say": "...", "then": [...]} to add follow-up steps after it.

  • conditions (array): Ordered list of conditions that define the conversation flow

    Each condition object has:

    • when (string): Natural-language description of the main agent's observable action, written from a third-person observer perspective (e.g. "The agent asks for your date of birth", "The agent confirms the cancellation"). Matched semantically against the conversation context.

    • say (string): What the scenario actor says or does, spoken verbatim. Wrap the whole step in <ai_generated>...</ai_generated> to have the actor improvise from it instead.

      • SSML pause tags: <silence time="1.5s" /> (interruptible) or <hold time="2s" /> (not interruptible). <silence> lets the main agent jump in mid-pause; <hold> enforces dead air.
      • Emotion markers: [laughter], [sigh], etc. (can repeat like [laughter] [laughter])
      • Special actions: <endcall /> to end the call
      • Action tags only work in verbatim steps, not inside <ai_generated>.

    • then (array of strings, optional): Follow-up steps in order. Each fires on the actor's next turn after one main-agent reply, regardless of its content. <interruption> is only allowed here.

Usage Tips:

  • Write when as third-person descriptions of what the main agent does (e.g. "The agent confirms the cancellation")
  • End with an <endcall /> step for clean call termination
  • Combine SSML tags and emotion markers naturally: "Great <silence time=\"1.5s\" /> [laughter] [laughter]"

List of tool IDs to use for evaluator

test_profileinteger

The test profile ID to use for the evaluator

phone_numberinteger

folder_pathstring nullable

Dot-separated path of the folder to assign this evaluator to (e.g. "Sales.Inbound"). Folders must be created before use — they are not auto-created. Use scenarios_create_folder_create to create each level before assigning evaluators. Example: to use "Sales.Inbound", first create "Sales", then create "Inbound" inside it.

generated_mock_tool_entriesunknown
first_messagestring

Opening line the simulated caller says to the agent. Defaults to "Hello".

max_durationinteger nullable

Max call duration in seconds for this scenario. If not provided or set to null, the scenario will use the project's max_call_duration setting. Valid range: 10-3600 seconds (10 seconds to 60 minutes) Example: 600 (10 minutes)

Scenario Instructions - format depends on scenario_type:

  • For instruction type: Plain text instructions
  • For conditional_actions type: JSON string with role, first_message and a conditions array. Each condition has when (a natural-language third-person description of the main agent's observable action — e.g. "The agent asks for your date of birth", matched semantically), say (spoken verbatim, with optional <silence time="1.5s" /> (interruptible) or <hold time="2s" /> (not interruptible) and [laughter] tags; wrap the whole step in <ai_generated>...</ai_generated> to improvise instead) and optional then follow-up steps. Responses return this format unless conditional_actions_format=legacy is passed. The earlier id-based format (id, condition, action, type, fixed_message) is still accepted on writes.
