Nit:
act_attributes = actual_args.get("attributes", [])There was a problem hiding this comment.
Can't take this one — get(k, default) only substitutes the default when the key is missing, and here it isn't.
An agent that adds no grouping doesn't omit the parameter: create_metric_alert serialises it as "attributes": null, so after json.loads the key is present holding None. The default is skipped, None reaches the isinstance check, and the result is False — a correct answer scored as a failure, on exactly the Attributes: [] fixture this PR adds.
{}.get("x", []) # -> [] key missing -> default used
{"x": None}.get("x", []) # -> None key present -> default ignoredSame thing already bit us on trigger, and the comment at line 107 records it: ".get(k, default) only returns the default when the key is ABSENT, but create_metric_alert serialises unset params as trigger: null".
or [] isn't available either — that was the earlier finding on this line: {} and "" would collapse to [], so a malformed argument would score as correct. One trap on each side, so both branches carry weight: is None for "nothing was passed", isinstance for "passed something that isn't a list".
Kept the code as is and added a comment naming the rejected form so it doesn't get re-proposed.
An alert can be narrowed two ways: a date entry in `filters`, or a date
group-by in `attributes`. Only the first was checked, and the second is
worse -- a group-by makes the alert fire per period value instead of on
the latest one, which is a different alert from the one the fixture
describes. An alert with `filters: []` and `attributes: [order_date.month]`
therefore scored 7/7 clean; a recorded GPT-5.2 run carried exactly that
invented month group-by and passed.
This activates coverage the dataset already carries. Item
e2a1e22a-2020-4a24-b3fe-2350315f7a73 ("...for any individual product
brand...") stores `"Attributes": [{"using": "label/product_brand"}]`, and
that key was dropped on the floor. It is the regression gate for this
change, not just the new unit tests.
The two sides cannot be deep-compared as raw dicts. Fixtures author the AAC
tool-input form, `{"using": "label/x"}`; `create_metric_alert` receives the
resolved AFM form, `{"localIdentifier": "a0", "label": {"identifier":
{"id": "x"}}}`, forwarded verbatim from `prepare_metric_alert_proposal`. So
`_attribute_label_ids` canonicalises both sides to a bare label id and the
comparison is a sorted multiset: order-insensitive, and the converter's
`localIdentifier` stops mattering without a strip step. Identity is all
that is compared -- `showAllValues` is the agent's to choose.
The asymmetry is specific to attributes. `Filters` in the same fixture is
already AFM-shaped, which is why `_check_filters` gets away with a raw
`_deep_subset` and is left alone.
Malformed input is split structurally rather than by side:
- Not a list of groupings at all -> False. The agent answered wrongly, and a
wrong answer is a FAIL. Raising would record an ERROR, which
`json_report.py` excludes from the failure count, so a malformed answer
would rank above a merely wrong one.
- A list holding an unreadable entry -> raises. Entries are typed
`AttributeItem` at the tool boundary, so the plausible cause is the wire
format moving, and that has to be unmissable rather than read as every
agent regressing at once. The same rule covers a `label/x` versus
`attribute/x` mix-up in a fixture.
The expectation side needs no guard beyond that: `_normalize_expected_output`
rejects a non-list before the run spends an API call, and `from_dict`, the
other way into the field, has no callers.
Deliberately not done: `generate_simulated_alert_response` is unchanged. An
`Attributes: []` expectation needs no support -- the simulated user does not
invent a grouping and the check verifies it did not. A non-empty expectation
does have a gap, but rule 3's "check ALL of these" list would have to grow
too for a symmetric rule to be honest, perturbing all 18 items to serve the
one that already requests its grouping in its own question. So: a non-empty
`Attributes` expectation requires the item's question to ask for that
grouping, and that requirement is documented on the normalizer.
Note for dashboards: `quality_score` for alert items moves from /7 to /8,
since both Langfuse sinks derive it as the fraction of true booleans in the
detail dict. Scores are not comparable across this commit, and
`attributes_correct` is a new score name.
The other half of GDAI-2175 -- whether the agent asked before proposing --
is not observable from final tool arguments and stays with
`verify_alert_asks_for_date` in gdc-nas.

Validate actual entries before the no-grouping shortcut.
If expected.attributes is [], an actual value such as {"attributes": [{}]} returns False at Line 196 before Line 197 validates the unreadable entry. This records an agent failure instead of exposing an AFM wire-format or judge error. Canonicalize act_attributes before the empty-expectation check, then test whether the canonical ID list is empty.
Proposed fix
- if not exp_attributes:
- return not act_attributes
- exp_ids = sorted(_attribute_label_ids(exp_attributes, side="expected"))
- act_ids = sorted(_attribute_label_ids(act_attributes, side="actual"))
+ act_ids = _attribute_label_ids(act_attributes, side="actual")
+ if not exp_attributes:
+ return not act_ids
+ exp_ids = _attribute_label_ids(exp_attributes, side="expected")
+ act_ids.sort()
+ exp_ids.sort()
return exp_ids == act_idsBased on learnings, an unreadable entry within a list must raise ValueError, even though a non-list top-level value must score False.

Summary
An alert can be narrowed two ways: a date entry in
filters, or a date group-by inattributes. Only the first was checked. The second is worse — a group-by makes the alert fireper period value instead of on the latest one, which is a different alert from the one the
fixture describes. An alert with
filters: []andattributes: [order_date.month]thereforescored 7/7 clean, and a recorded GPT-5.2 run carried exactly that invented month group-by and
passed.
This activates coverage the dataset already carries, it is not a forward-looking change.
Item
e2a1e22a-2020-4a24-b3fe-2350315f7a73("Alert me every time returns for any individualproduct brand go above 30 in the last day") stores
"Attributes": [{"using": "label/product_brand"}], and that key was dropped on the floor. It isthe regression gate for this change, not just the new unit tests. QA's rewritten
c2f8b8edcarrying
"Attributes": []is the second beneficiary.For the GDAI-2175 fix itself the eval could not serve as a before/after metric at all — it
reported 9/9 both before and after. That blind spot is what this closes.
Why the two sides cannot be deep-compared
This is the trap the first attempt fell into. The expectation and the actual use different
vocabularies for the same grouping:
expected_output["Attributes"]{"using": "label/x"}create_metric_alertargument{"localIdentifier": "a0", "label": {"identifier": {"id": "x", "type": "label"}}}The conversion happens in gdc-nas
prepare_metric_alert_proposal(_resolve_afm_slicing→build_afm_execution_payload_from_query), whose result is exposed asafm_attributes,documented "forward verbatim as create_metric_alert 'attributes'".
So
_attribute_label_idscanonicalises both sides to a bare label id and the comparison is asorted multiset — order-insensitive, and the converter-assigned
localIdentifierstopsmattering without a strip step. Identity is all that is compared;
showAllValuesis the agent'sto choose.
The asymmetry is specific to
attributes.Filtersin the same fixture is alreadyAFM-shaped (
relativeDateFilter), which is why_check_filtersgets away with a raw_deep_subsetand is left untouched here.An unrecognised entry shape, or a URI prefix other than
label/, raises —label/xandattribute/xare different objects, and a new spelling must fail loudly rather than compareunequal and read as the agent being wrong. The expectation side is validated in
_normalize_expected_attributes, so a malformed fixture fails before the run spends an APIcall; either way
cli/agentic_runner.pycontains it to that item's own row.Decisions taken deliberately
generate_simulated_alert_responseis unchanged. AnAttributes: []expectation needs nosupport: the simulated user does not invent a grouping and the check verifies it did not. A
non-empty expectation does have a gap, but rule 3's "check ALL of these" list would have to
