agent marked a timeout flaky without checking the logs — the test wa

Not specified by the original author.

TL;DR

A test whose runtime triples on every failure is not flaky. It is a regression that sometimes crosses the timeout. The agent must compare failure durations against the test's own history before applying the flake label. Add a timing check to the triage policy: if failing runs are consistently 2x or more the passing median, label it a performance regression and open a bug, not a quarantine.

The query

agent classified a timeout as flaky even though the test's runtime tripled in every failure - how to catch a regression hiding in flake labels

Use this when

• Timeouts are auto-labeled flaky but failing runs are consistently slower than passing runs.
• A test's runtime has drifted upward and the classifier never noticed.
• You suspect a latency regression is hiding behind the flake label.

Not for

• Genuine network-timeout flakes where failing runs show normal durations.
• Tests with no timing history to compare against.
• Timeouts caused purely by an overloaded CI runner (all tests slow, not one).

Steps

Step 1: Pull the timing history for the test

grep -h "test_payment_retry" reports/junit-*.xml | grep -o 'time="[0-9.]*"' | sort -n

Expected output: a sorted list of durations across recent runs. You need at least 20 passing runs to establish a baseline. If the CI system stores timing in a dashboard instead, export the same series from there.

Step 2: Compare failing-run durations against the passing baseline

python -c "
import statistics
passing = [4.1, 4.3, 3.9, 4.2, 4.0]
failing = [12.8, 13.1, 12.4]
print('passing median', statistics.median(passing))
print('failing median', statistics.median(failing))
print('ratio', statistics.median(failing) / statistics.median(passing))
"

Expected output: the ratio. In the example it is about 3x. Any consistent ratio at or above 2x means the failures are slow for a reason, and "flaky" is the wrong label.

Step 3: Find what got slow in the failing runs

grep -B 5 -A 20 "test_payment_retry" ci-logs/failing-run.log | grep -iE "slow|wait|lock|retry|timeout" | head -20

Expected output: the slow step inside the test (a database call, an HTTP retry, a lock wait). The tripling runtime has a cause, and it is usually one call that got slower, not the whole test.

Step 4: Relabel and file the regression

Record the decision in triage-decisions.log: testpaymentretry - 3x runtime on failures, relabeled perf-regression, not flaky.

Expected output: the decision is recorded with the evidence (the ratio from step 2). The test is now tracked as a performance regression with an owner, not silently quarantined as a flake.

Step 5: Fix the classifier to require timing evidence

flake_classifier:
  require_timing_check: true
  max_fail_to_pass_ratio: 2.0

Expected output: the agent can no longer label a timeout flaky without comparing durations. A timeout with a 2x-plus slowdown ratio is routed to the regression queue automatically.

Step 6: Add a runtime-drift alert for the suite

Add a monitoring rule: alert if any test's 7-day median runtime exceeds 1.5x its 30-day median.

Expected output: the next slowdown gets caught as drift before it starts tripping timeouts, so the classifier never has to choose between "flaky" and "slow" again.

Variant phrasings

agent bumped the timeout to 60s and called it fixed

Bumping the timeout hides the regression the way quarantine hides the race. Steps 2-3 find the real slowdown; the timeout stays where it was.

flake classifier trusts green reruns but the rerun ran on a different runner

A green rerun on a bigger runner proves nothing about the code. Step 2's ratio uses the test's own history on comparable runners.

test passes on retry so the agent closed it as flaky

Passing on retry is necessary but not sufficient evidence. The timing check in step 5 is the missing half of the verdict.

Why it happens

Timeouts have two causes: slow code and slow environments. The classifier only checked the symptom (it timed out, then passed on retry) and never the durations. A regression that triples runtime will pass on retry whenever the slow path happens to be fast that run, which looks exactly like flakiness to a classifier that ignores timing. The label was wrong because the evidence was incomplete, not because the classifier is stupid.

Edge cases

• If all tests on the runner are slow during the failing runs, the cause is the runner, not the test. Compare the test's slowdown against the suite-wide slowdown before relabeling.
• A test with high natural variance (integration tests hitting real services) needs a wider ratio threshold. Tune step 5's 2.0 per test type.
• Do not delete the timeout to "prove" it is slow. The timeout is the safety net. Measure around it.
• The first few runs after a deploy can be slow (cold caches, JIT warmup). Exclude post-deploy runs from the baseline or the ratio will false-positive.
• If the slowdown is in test setup rather than the code under test, the regression is in the test infrastructure. File it there, not against the product code.

TL;DR

Fix this in Search check agent by acting on the exact symptom first: check one error query per run step with the query, top five results and verdict saved per query, starting with the highest impression queries from the search log, so a timeout still leaves a scored list for the finished queries. Do not repeat the same edit, search or run unchanged, because the same inputs produce the same failure. Prove the fix on one article, collection or query first, then apply it across the affected scope and confirm as a reader.

Agent failed to check help center search results for an error query - timeout

Use this when

• Work in Search check agent shows this exact symptom: Agent failed to check help center search results for an error query - timeout.
• The same symptom repeats after a retry with unchanged inputs.
• Readers or support agents are blocked until this item is corrected.

Not for this skill when

• The help center platform itself is down or returning outage notices. Resolve that first, then return here if this symptom remains.
• The content is correct and you only want a style or tone rewrite. That is an editorial pass, not this fix.

Steps

1. Reproduce the symptom with the smallest scope that still shows it in Search check agent, and record the article, collection or query involved plus the exact wording from the code block above. Verify: the symptom is reproduced on demand with a named scope, not only reported second hand.
2. Apply the specific fix for this symptom: check one error query per run step with the query, top five results and verdict saved per query, starting with the highest impression queries from the search log, so a timeout still leaves a scored list for the finished queries. Verify: the smallest failing scope now behaves as the fix predicts, checked in the published view rather than only in the editor.
3. Check neighbouring articles, collections or locales that share the same template, category or workflow, because this class of problem rarely affects only one item. Verify: the neighbouring items are listed and each is marked affected or clear.
4. Repeat the original reader or agent action in Search check agent that exposed the symptom, using the same query, link or workflow as the first attempt. Verify: the action completes and the original symptom does not appear.
5. Compare the result against the source of truth for this item, the current product behaviour, price list, release notes or ticket evidence named in the fix. Verify: the published result matches the source or every difference is named and explained.
6. Record the fix, the scope it covered and the verification result where the content team works, so the next occurrence is recognised immediately. Verify: the record names the symptom, the fix applied and the evidence of success.

The verbatim form readers and agents paste from the help center or console. Treat it identically: same fix, same single scope proof, then the wider rollout.

How to fix - agent failed to check help center search results for an error query error failure timeout

The how to phrasing for the same problem in Search check agent. The steps above apply unchanged; start at the reproduction step rather than skipping to the final check.

Search check agent troubleshooting for this symptom

The symptom first phrasing used when the full message is hidden. Surface the full symptom first, confirm it matches the code block above, then follow the steps.

Why it happens

Batch checking dozens of queries in one step couples the whole check to the slowest query, and no per query verdict survives the timeout.

Edge cases

• The symptom appears in one locale, collection or audience view only. Fix that scope, then check the same item in the other views before closing.
• A cached or indexed copy keeps showing the old state after the fix. Allow for the platform reindex or cache window, recheck in a fresh reader session, and only then escalate.
• Two items have near identical titles. Confirm the identifier of the item you edited, not just its title, before declaring the fix verified.

Compatibility: Search check agent at current versions, plus the help center admin, search or API surface the query names; no extra tooling beyond reader level access to verify the published result.

TL;DR

Skipping a flaky test file hides the failure; quarantining it manages the failure. The policy: a quarantine label with the reason, an owner, and an expiry date; the test keeps running in a separate quarantine lane whose results are tracked; skipping without all three is rejected. Visibility first, then the fix.

Error

agent skipped the flaky test file entirely instead of quarantining: policy fix

The agent "resolved" flakiness by skipping the whole file. The flake is now invisible, unowned, and will never be fixed.

Steps

1. Find the skips: list test files or cases the agent skipped and identify which were flaky rather than obsolete. Expected output: a skip inventory with reasons.
2. Convert flaky skips to quarantine entries: reason, owner, expiry date, and a link to the flake evidence. Expected output: a quarantine register, not silent skips.
3. Set up the quarantine lane: quarantined tests run separately on a schedule, and their results are tracked over time. Expected output: ongoing signal on every quarantined test.
4. Reject bare skips in the healing lane: a patch that adds a skip without a quarantine entry fails review. Expected output: an enforced policy.
5. Review the register on expiry: fix, re-quarantine with a new date, or delete. Expected output: no test quarantined forever by default.

When to use

• Flaky tests keep getting skipped instead of quarantined.
• The skip count grows and nobody owns the skipped tests.
• You want flakiness visible and managed, not hidden.

When not to use

• The test is obsolete (delete it; quarantine is for tests worth keeping).
• The test is skipped for a valid environmental reason with a documented condition (that is a conditional skip, not flakiness).
• You are doing a one-off triage and will convert skips to quarantine entries right after (fine, but do the conversion).

Variant phrasings

Agent marked the flake xfail and moved on

xfail without ownership is a skip with extra steps. Same quarantine policy applies.

Agent skipped the file "temporarily" six months ago

Temporary skips without expiry dates are permanent. The expiry date is the load-bearing part of the policy.

Quarantine lane results nobody reads

A quarantine lane without review is a slower skip. Assign the review to a rotation with a real cadence.

Why it happens

The agent is graded on green suites, and skipping is the fastest path to green. Quarantine is more work: labels, owners, lanes, reviews. Without a policy that makes bare skips fail review, the agent will always choose the skip, and the organization slowly goes blind to its flakes.

Edge cases

• A quarantine lane that fails too often trains people to ignore it; keep the lane's signal clean and act on its results.
• Expiry dates need enforcement; an expired quarantine with no review should page the owner, not linger.
• Deleting a long-quarantined test is a legitimate outcome; require the deletion to be a deliberate decision with the flake history attached.
