Evaluate Trace

Use this skill when the user wants to evaluate traces with an existing live evaluation endpoint.

Interactive Q&A protocol (mandatory)

If context does not make scope clear, ask one question at a time using the structured question tool (loaded per the HARD-GATE above).

Example question structure:

Do you want to evaluate one trace or a batch?
A) One trace now
B) Small batch (up to 25)
C) Full batch loop

Rules:

  • Ask exactly one clarifying question per message.
  • Use the structured question tool for every question. Structure each with a short header, 2-4 options with labels and descriptions, and place the recommended option first. Do not add "(Recommended)" or similar annotations to option labels.
  • Ask a single follow-up if needed, then proceed.

Workflow

  1. Identify target live evaluation:
    • If live evaluation id is unknown, call list_live_evaluations.
    • Select public_id and verify required input_columns.
  2. Prepare inputs:
    • Ensure inputs keys exactly match input_columns.
    • Include media_url for multimodal evaluations when needed.
  3. Execute evaluation:
    • Use the run_eval tool with live_evaluation_id and inputs for each trace.
  4. Return useful outputs:
    • run_id
    • per-judgment scores/outcomes
    • brief interpretation for next action
  5. Optional handoff:
    • If human judgment is needed, route to review-and-promote-traces.

Batch mode guidance

  • Use deterministic trace ordering and log run_id for each input.
  • Apply retries with stable idempotency context in caller logic if needed.
  • Summarize failures by category or threshold, then propose review handoff.

Scopes reference

  • list_live_evaluations requires live-evaluations:read
  • run_eval requires live-evaluations:execute

If a scope error occurs, ask the user to create an API key with the missing scope in Truesight Settings.
