Follow-up to GDAI-2200, which closed with "no gen-ai change, fix in the eval". This is the harness-side half — minus the budget raise, for reasons below.

The problem

Every agentic evaluator drives the agent through a simulated-user loop that can exit several ways. Only "the agent produced its output" was ever recorded. A run that ran out of turns while doing the right thing is reported identically to one that refused, and identically to one that answered wrongly.

It's worse than a missing field, because every downstream check has the form produced_output and <check>. An exhausted alert run reports:

{"alert_created": false, "operator_correct": false, "threshold_correct": false,
 "metric_correct": false, "recipients_correct": false}

Four specific-sounding content failures for work the agent was never given the chance to attempt. That false precision is the same objection raised internally about stalled visualization runs.

What this adds

LoopExit in core/models.py, threaded through all five loops, plus turns_used and max_iterations in detail:

value meaning
success the agent produced its output
agent_silent neither text nor a tool call — genuinely stuck
budget_exhausted hit max_iterations; says nothing about being on track
simulated_user_failed our simulated-user model failed, not the agent
chat_error the chat call raised mid-conversation (kda partial path)
not_run the loop never started (conversation $ref skip)

The field defaults to BUDGET_EXHAUSTED and every other exit assigns explicitly, so a loop that simply runs out of range() is labelled correctly without a trailing else.

Two exits were previously invisible, and they're the reason this is worth doing:

  • metric_skill catches SimulatedResponseError and breaks. A failure of our own gpt-4o-mini was scored against the product as metric_created=False, maql_correct=False.
  • kda_skill breaks on a chat error with a partial result.

Deliberately not included

  • No verdict changes. An exhausted run still fails. The point is that the cases become countable, not that any start passing.
  • No change to any max_iterations default (4–7, already tuned per kind). GDAI-2200 estimates ~13% of alert runs need 7 turns against a ceiling of 6 — but raising the ceiling first would hide its interaction with GDAI-2199's MANDATORY STOPs, which make prescribed end-turn-without-a-tool-call behaviour consume budget. With exit_reason in place, "is this budget too tight" becomes answerable from data instead of argued.
  • No try/except around alert_skill's simulated-user call. There a failure already propagates as a hard error rather than being swallowed into a content failure, which is the behaviour we want. Only metric_skill needed the label.

Tests

Existing detail assertions extended across all five kinds, plus dedicated coverage for budget_exhausted vs agent_silent vs success (including which turn the tool landed on), simulated_user_failed, and a regression guard asserting two runs with identical scored booleans differ only in exit_reason — the exact ambiguity this removes.

739 passed, ruff check clean. ruff format reports the same 8 pre-existing files as master — none added.

Summary by CodeRabbit

  • New Features

    • Evaluation results now show why agentic runs ended, including success, silence, errors, simulated-user failures, skipped turns, and budget exhaustion.
    • Results include turns used, reasoning steps, and configured iteration limits across conversation, alert, KDA, metric, and visualization evaluations.
    • KDA evaluations now support configurable pass/fail gates.
  • Bug Fixes

    • Chat and simulated-user failures are recorded without discarding completed evaluation runs.
  • Tests

    • Added coverage for exit reasons, counts, limits, failures, and scoring details.

📝 Walkthrough

Walkthrough

The change adds shared loop-exit classifications. Conversation and skill evaluations now record exit reasons, turn counts, iteration limits, reasoning steps, and handled chat or simulated-user failures.

Layer / File(s) Summary
Exit contract and conversation tracking
packages/gooddata-eval/src/gooddata_eval/core/models.py, packages/gooddata-eval/src/gooddata_eval/core/agentic/conversation.py
Adds LoopExit. Conversation turns now record exit reasons, clarification counts, and chat-error state. Conversation scoring includes turns, steps, and clarification rounds.

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Assert propagation for non-chat RuntimeError.

This test expects run_agentic_kda_skill to return a summary when send_message raises RuntimeError. Replace that assertion with pytest.raises(RuntimeError). A failed request may leave total_turns == 0; turns_used records the attempted request.

metric_created=False alone cannot separate a run that ran out of turns, one where
the agent went silent, one where the harness's own simulated user failed, and one
that was refused. Each run now records which of those ended it, so a failing item
can be diagnosed without replaying it, and a chat or simulated-user fault is
recorded against the run rather than aborting the whole item.

…ts cannot leak

A stream that broke AFTER create_metric or create_metric_alert had already
succeeded left the object behind in the workspace, where the next run found it and
scored against it. The partial result carries what the call managed to do, so it is
read and cleaned up instead of discarded with the error.
