Summary

  • generate_simulated_response() only received the assistant's last message and the ground-truth MAQL, and its prompt forced every clause of that MAQL to be satisfied "even if the assistant's question doesn't explicitly ask about it" — so the simulated user would inject filters/constraints the original request never mentioned, even when the assistant's proposal already matched it.
  • Threaded the original question through (_execute_single_metric_run already has question in scope; conversation.py's TurnDefinition.message carries the same for multi-turn agent_conversations), and rewrote the prompt to agree when the original request is already satisfied, only adding a clause when it's a reasonable reading of that request.

Test plan

  • pytest packages/gooddata-eval/tests/test_agentic_metric_skill.py packages/gooddata-eval/tests/test_agentic_conversation.py -q — 50 passed
  • Full gooddata-eval suite — 464 passed
  • ruff check on changed files — clean (3 pre-existing unrelated errors elsewhere in the package, untouched by this change)
  • Added a regression test (test_generate_simulated_response_prompt_agrees_when_the_original_request_is_already_satisfied) reproducing the QA-29094 scenario (chatbot proposal already satisfies the original ask → simulated user must agree, not inject a new filter)
  • Updated the existing test_generate_simulated_response_prompt_preserves_maql_fidelity assertions to match the new conditional prompt wording (dropped the now-removed "every clause" unconditional phrase, kept the verbatim/filter-fidelity checks it originally guarded)

📝 Walkthrough

Walkthrough

The metric clarification flow now passes the original user question to simulated response generation. The prompt uses the question and expected MAQL to evaluate proposals. The flow logs metric-branch errors with turn details. Tests cover prompt content, call arguments, filter guidance, and error paths.

generate_simulated_response receives the original question. Its prompt uses the question and expected MAQL. _no_filter_hint detects a standalone WHERE outside identifiers and quoted literals. Escaped characters remain inside quoted MAQL literals. Metric-branch exceptions now include the turn ID and error details in logs.

Addressed all 5 findings from review:

P1-1 (clarifying question branch missing) — added an explicit prompt branch: if the assistant is asking a clarifying question (no proposal yet), the simulated user now answers directly from the ground-truth MAQL instead of trivially agreeing.

P1-2 (no deterministic no-filter guard) — extracted _no_filter_hint(): when the ground-truth MAQL has no WHERE clause, the prompt now explicitly tells the simulated user no filter is needed, instead of relying on the LLM's judgment of what the original request "implies" (the same fuzzy reasoning that caused the original bug).

P2-1 (uncovered call site + silent except) — added a direct unit test for _get_sim_user_response's metric branch (previously 0% coverage, confirmed via --cov), and changed except Exception: pass to log the exception instead of swallowing it.

P2-2 (dropped max_tokens assertion) — restored assert call_kwargs["max_tokens"] >= 300 in the fidelity test.

P2-3 (brittle prose assertions) — reduced the new tests' reliance on exact prompt wording; they now mostly check interpolated data (original_question/expected_maql presence) and the independently-testable _no_filter_hint() output rather than full sentences.

468 tests passing (was 464), ruff clean, coverage gap on conversation.py's metric branch closed.

CodeRabbit finding on PR #1760: _no_filter_hint()'s naive "WHERE" in
maql.upper() check false-positives on identifiers/literals that merely
contain the substring (e.g. {metric/somewhere_sales}), silently omitting the
no-filter hint even though the MAQL has no real WHERE clause.

Reuse the existing _PROTECTED_RE (same protected-span rule already used by
_casefold_outside_protected) to strip {type/id} identifiers and quoted
literals before matching \bWHERE\b.

Two comments on the QA-29094 fix — the direction looks right and the new test coverage (especially test_get_sim_user_response_metric_branch_forwards_the_turn_message) is a solid addition. Both points below are about scope and about the part of the stated root cause that is still open.

…uest

generate_simulated_response() only saw the assistant's last message and the
ground-truth MAQL, and was instructed to force every clause of that MAQL to
be satisfied "even if the assistant's question doesn't explicitly ask about
it" -- so it would inject filters/constraints the user's original request
never mentioned, even when the assistant's proposal already matched it.

- Thread the original question through (metric_skill.py's
  _execute_single_metric_run already has it in scope; conversation.py's
  TurnDefinition.message carries the same for multi-turn conversations) and
  rewrite the prompt to agree when the original request is already
  satisfied, only adding a clause when it's a reasonable reading of that
  request -- not an unconditional replay of expected_outputs[0].
- Add an explicit branch for the dominant real case: the assistant asking a
  clarifying question with no proposal yet. Without it, the simulated user
  could trivially agree ("nothing proposed yet" == "satisfied") and stall
  the conversation, burning iterations without ever supplying the agent a
  usable answer.
- Replace fuzzy "is this filter a reasonable reading of the request"
  judgment with a deterministic _no_filter_hint(): when the ground-truth
  MAQL has no WHERE clause, the prompt explicitly tells the simulated user
  no filter is needed, closing the exact loophole that caused the bug.
  Matches WHERE as a standalone keyword outside {type/id} identifiers and
  quoted literals (reusing the existing _PROTECTED_RE / same rule as
  _casefold_outside_protected), so a substring like
  {metric/somewhere_sales} isn't mistaken for a real clause.
- conversation.py's metric branch (forwards to
  metric_skill.generate_simulated_response) had 0% test coverage behind a
  bare `except Exception: pass` -- a future signature mismatch would
  silently fall through to the generic fallback prompt. Log the exception
  and add a direct unit test for the branch.
- Restore the max_tokens >= 300 assertion, and reduce the new tests'
  reliance on exact prompt-prose assertions in favor of checking the
  interpolated data and the independently-testable _no_filter_hint() output.

Verified locally: ran the full agent_metric_skill (8 cases) and
agent_conversations (10 cases) suites against ecommerce_demo on
tavern-frank-test -- 18/18 passing with this fix.
