Summary

  • detail.latency_breakdown (Per-tool-call/reasoning-step latency breakdown (detail.latency_breakdown) #1758) was wired into only the 9 test kinds gdc-mic-ai-evaluation currently has enabled — not the SDK's full kind catalog. This closes the gap for the 5 kinds that were skipped purely by scope, not by any technical limitation:
    • metric_skill, alert_skill (single-turn evaluators — same ChatResult signature as visualization/general_question, which already have it)
    • agentic_search, agentic_general_question (single-message agentic kinds)
    • agentic_kda_skill (multi-turn simulated-user loop — needs per-turn timestamp/index re-offsetting, since its loop can span multiple turns)
  • dashboard_summary is deliberately excluded: it calls a plain REST /summary endpoint, not the chat/SSE pipeline (core/summary/http_client.pyChatResult.model_validate({"textResponse": summary}), nothing else populated). It has no tool-call or reasoning-step events to report at all; wiring it in would only ever produce an empty list.

Shared helper (per review)

The per-turn timestamp/index rebasing was hand-copied identically across alert_skill, metric_skill, visualization and conversation, and agentic_kda_skill needed it a fifth time. Extracted into one shift_and_index_events() in models.py; all five call sites now use it, so there's one implementation rather than five that can drift. Verified no inline offset arithmetic remains outside the helper.

Rebased onto #1771

#1771 restructured the same K-run loops this PR threads events through, so this was re-applied onto the new shapes rather than resolved as markers:

Test plan

  • uv run pytest packages/gooddata-eval/tests/702 passed, 0 failed (on the rebased tree)
  • test_run_agentic_kda_skill_shifts_timestamps_and_indices_across_iterations — asserts the real rebasing math across two iterations: call_ts/result_ts shifted by iteration 1's turn_wall_clock_sec (10.2/10.3 and 10.3/10.4), tool index from 0 (iteration 1 had no tool calls) while the reasoning index starts from 1 (it had exactly one step). Fails if either offset is dropped or applied twice — re-run and passing after the rebase.
  • Per-run event-propagation guards for search_tool and general_question, each using side_effect with distinct ChatResult objects per run so a double-mutation bug can't pass silently.
  • ruff check / ruff format --check — clean across the package (85 files)

Summary by CodeRabbit

  • New Features
    • Evaluation results now include latency breakdowns for successful and failed agentic evaluations.
    • Latency details are available for general questions, KDA skills, search tools, alerts, and metrics.
    • Evaluation outputs retain tool-call and reasoning-step event details for performance analysis.
    • Multi-turn evaluations consolidate event timing and indexing across turns, including partial results from failed requests.
    • Results now report effective and passed run counts, timing information, unscored runs, and judge errors.
    • Evaluations can receive user context and support configurable trace-link submission.

…on every K-run

Only the first (conv_id_0) GeneralQuestionResult/SearchResult construction
populated the new tool_call_events/reasoning_step_events fields -- the loop
handling runs 2..K used a differently-indented literal that an earlier
replace_all missed, so those runs kept the dataclass's empty-list default.
Selecting one of those later runs as `best` silently produced an empty
detail.latency_breakdown despite the run having real tool calls/reasoning.

Caught by CodeRabbit on PR #1772, reproduced with a k=2 regression test
per file before fixing.

The mechanical parts look right. Both the first-run block and the retry-loop block in general_question.py and search_tool.py got the propagation, so the K>1 gap is genuinely closed, and adding the breakdown to the early-return detail dicts in metric_skill/alert_skill means a failed item no longer silently loses its telemetry. Three things worth addressing.

1. _accumulate is untyped, and that costs more than style.

def _accumulate(result) -> None:

result is unannotated, so it's inferred as Unknown and every attribute access in the body is unchecked — result.tool_call_events, result.turn_wall_clock_sec, all of it. I confirmed this isn't something our tooling can catch for us:

def _accumulate(result) -> None:
    print(result.anything_at_all.nonexistent)

ty check reports All checks passed! on that. Unannotated parameters are gradual typing, which is legal, so ty is correct to stay silent — no configuration change would make it complain. And ANN001 (the rule that would flag it) isn't in our ruff lint.select. So CLAUDE.md's "type everything" is currently unenforced for parameters, and this is the failure mode.

Annotating it as ChatResult restores checking over the whole function.

2. It's a verbatim copy of conversation.py:341-359.

Same offset shifting, same index rebasing, same turn_offset += turn_wall_clock_sec. This PR creates the second copy, which makes it the natural moment to extract it — something like shift_events(events, *, turn_offset, tool_index_offset, reasoning_index_offset) alongside build_latency_breakdown in models.py. Two hand-maintained copies of timeline-rebasing arithmetic will drift, and the failure mode is a quietly wrong timeline rather than an exception, so nothing will tell us when it does.

3. The most intricate new logic has no test.

The added kda tests only assert "latency_breakdown": []. Nothing exercises _accumulate across iterations — that turn 2's call_ts is shifted by turn 1's wall clock, and its index rebased past turn 1's event count. That's exactly where an off-by-one or a double-shift hides, and it's the part of this PR that isn't a one-line propagation. A two-iteration disambiguation run asserting the shifted timestamps would cover it; conversation.py presumably has something similar to mirror.

Two smaller notes:

  • _accumulate mutates the event objects in place, so calling it twice on the same object double-shifts. Safe against a real server (each response is a fresh object), but the new general_question and search_tool tests use send_message.return_value = <single ChatResult>, so both runs share the same event objects. The assertions pass, but they don't demonstrate the per-run independence the docstrings claim — side_effect with two distinct results would.
  • turn_offset advances by turn_wall_clock_sec only, so the LLM time inside generate_simulated_kda_response / _get_sim_user_response isn't included and inter-turn gaps compress in the reconstructed timeline. Pre-existing in conversation.py, not this PR's doing, but now it's true in two places and worth one comment wherever the shared helper ends up.

… it, test it

Addresses hkad98's review on #1772:

- _accumulate (kda_skill.py) was untyped, so every attribute access inside
  it (result.tool_call_events, result.turn_wall_clock_sec) went unchecked --
  annotating it as ChatResult isn't enough on its own if the underlying
  logic stays duplicated, so:
- Extracted the turn-offset/index-rebasing arithmetic -- previously
  hand-copied identically across alert_skill.py, metric_skill.py,
  visualization.py, conversation.py, and now kda_skill.py -- into one
  shared shift_and_index_events() in models.py. All five call sites now
  use it instead of maintaining five copies that can silently drift.
- Added a real regression test exercising the actual new logic: two KDA
  iterations, asserting the second iteration's call_ts/result_ts are
  shifted by the first iteration's turn_wall_clock_sec and its tool/
  reasoning indices are rebased past the first iteration's own counts --
  not just that latency_breakdown ends up non-empty.
- Fixed the general_question/search_tool regression tests to use distinct
  ChatResult objects per mocked run (side_effect) instead of one shared
  return_value -- the previous version couldn't have caught a
  double-shift bug, since both runs pointed at the same already-mutated
  object.

@hkad98 all three addressed in b37afd4:

  1. _accumulate now typed as ChatResult.
  2. Extracted the turn-offset/index-rebasing arithmetic into shift_and_index_events() in models.py — used it not just in kda_skill.py but retrofitted the 4 pre-existing copies too (alert_skill.py, metric_skill.py, visualization.py, conversation.py), so there's one implementation instead of five that could drift.
  3. Added a real 2-iteration regression test asserting the actual rebasing math: iteration 2's call_ts/result_ts shifted by iteration 1's turn_wall_clock_sec, tool index starting from 0 (iteration 1 had no tool calls) while the reasoning index starts from 1 (iteration 1 had one reasoning step) — the exact off-by-one/double-shift case you flagged.

Also fixed the two smaller notes: general_question/search_tool's new tests now use side_effect with two distinct ChatResult objects per run instead of one shared return_value, so they'd actually catch a double-shift bug now.

Left the turn_offset / simulated-user-generation-time gap as-is per your suggestion — pre-existing in conversation.py, now true in the shared helper too, worth its own follow-up rather than scope-creeping this one.

Full suite green (476 passed), lint/format clean.

Re-reviewed b37afd4. All three verified, and the extraction went further than I asked — approving on the code.

1. Typing. _accumulate(result: ChatResult) — the body is now checked rather than silently Unknown.

2. Extraction. shift_and_index_events() in models.py is arithmetically identical to what it replaced, and you retrofitted all five call sites (kda_skill, alert_skill, metric_skill, visualization, conversation) rather than just the new one. I diffed each against its original:

  • The offset increments now happen inside the helper, i.e. before the caller's all_*_events.extend(...), whereas four of the five sites previously incremented after. Nothing between the old and new positions reads turn_offset/*_index_offset, so this is behaviour-preserving at every site — including visualization.py, where turn_offset += ... had been sitting at the very end of the block after reasoning_steps.extend and response_id.
  • Returning the three offsets as a tuple keeps the helper honest about the caller still owning event accumulation, and the docstring says why. Good call.

Going from one implementation to five callers of one is a strictly better outcome than the "extract for the second copy" I suggested.

3. The test. test_run_agentic_kda_skill_shifts_timestamps_and_indices_across_iterations asserts the real math, not just presence: 10.2/10.3 for the create call and 10.3/10.4 for execute (iteration 1's turn_wall_clock_sec of 10.0 plus each within-turn call_ts), tool index from 0 because iteration 1 had no tool calls, reasoning index from 1 because it had exactly one step. That asymmetry between the two index streams is precisely the off-by-one I was worried about, and this test fails if either offset is dropped or applied twice. The side_effect-with-distinct-objects change in the general_question/search_tool tests closes the double-mutation hole too.

Agreed on deferring the turn_offset / simulated-user-generation-time gap — it's pre-existing and now lives in one place, which is a better position to fix it from.


One blocker left, and it isn't yours: the PR is now CONFLICTING. #1771 (judge faults / run counts / trace linking) landed on master and rewrote the same regions:

File Lines changed by #1771
agentic/general_question.py 262
agentic/kda_skill.py 187
core/models.py +38

Six files conflict: alert_skill.py, general_question.py, kda_skill.py, metric_skill.py, search_tool.py, models.py.

This is more than marker-resolution — #1771 restructured the K-run loops and run-result plumbing that this PR threads events through, and it added its own block to models.py right where shift_and_index_events goes. Worth rebasing carefully rather than taking either side wholesale, and re-running the new 2-iteration kda test afterwards, since it's the thing that will actually catch a mis-resolved offset. Ping me if the rebase forces changes to the shift logic itself and I'll take another look; if it comes out clean, this is good to merge.

…inds

latency_breakdown (#1758) was wired into only the 9 test kinds the downstream
consumer had enabled, not the SDK's full kind catalog. This closes the gap for
metric_skill, alert_skill, agentic_search, agentic_general_question and
agentic_kda_skill -- all of which already receive real tool_call_events/
reasoning_step_events through the same chat pipeline as their wired siblings.

dashboard_summary is deliberately excluded: it calls a plain REST /summary
endpoint, not the chat/SSE pipeline, so it has no tool-call or reasoning-step
events to report at all.

Also extracts the per-turn timestamp/index rebasing -- previously hand-copied
identically across alert_skill, metric_skill, visualization and conversation,
and needed a fifth time for agentic_kda_skill's simulated-user loop -- into one
shared shift_and_index_events() in models.py. All five call sites use it, so
there is one implementation rather than five that can drift.

Tests: a two-iteration kda test asserts the real rebasing math (iteration 2's
call_ts shifted by iteration 1's turn_wall_clock_sec, tool index from 0 while
reasoning index starts from 1), plus per-run event-propagation guards for
search_tool (which still builds its result in two places) and general_question.

Rebased onto #1771, which restructured the same K-run loops: general_question
now builds all K runs and one shared detail dict in a single place, so the
propagation fix collapses to one site there; search_tool still has two.

@hkad98 thanks for the detailed re-review — and you were right that the rebase was the real work, not marker resolution. Rebased onto 45892f79 (master with #1771) as d61e7a73; mergeable_state is back to blocked (pending review) rather than dirty.

Re-applied onto #1771's new shapes rather than taking either side wholesale:

  • general_question.pyperf: take Langfuse trace linking off the eval item critical path #1771 consolidated all K runs into one _run_single_general_question() and built one shared detail dict for both the pass and fail paths. So the event population and the latency_breakdown key each collapse from two sites to one, and the whole per-run-gap bug class you and CodeRabbit caught earlier is now structurally impossible there. Kept a guard test anyway, reframed to say why.
  • search_tool.py — still constructs SearchResult in two places (run 0 and the k>1 loop), so that risk is live; both populated, and the regression test covers exactly it.
  • kda_skill.py_run_once unchanged in shape, so the accumulation re-applied cleanly via the shared helper.
  • models.pyperf: take Langfuse trace linking off the eval item critical path #1771's AgenticAssertionError landed adjacent to, not overlapping, shift_and_index_events.

The shift logic itself did not need changing, so per your note I don't think this needs another look on that front — but the canary you named is the evidence: test_run_agentic_kda_skill_shifts_timestamps_and_indices_across_iterations re-run and passing after the rebase, still asserting 10.2/10.3 and 10.3/10.4 with the asymmetric tool-index-from-0 / reasoning-index-from-1 split.

Full suite 702 passed, 0 failed on the rebased tree (up from 476 — #1771 brought a lot with it), ruff check/format --check clean across all 85 files. Also folded your inter-turn-gap note into the shared helper's docstring, since it now applies in one place instead of five.
