Fix tracing-ui QE agent skill's FLAKY misdiagnosis of a suppressed crash - #85649
Conversation
The qe-agent's tracing-ui skill misdiagnosed a real product bug as FLAKY on openshift/distributed-tracing-console-plugin#306: Tempo omits the `traces` field from `/api/search` on zero-match queries, crashing `@perses-dev/tempo-plugin`'s response parser. Cypress support/e2e.js suppresses that exact crash signature (Cypress.on('uncaught:exception', ...) returning false for 'Cannot read prop'/etc.), so the test only ever times out waiting for an element that never renders, and the real error — logged via browser console, not the Node process — never reaches qe-agent-commands.log or the JUnit XML. A single passing rerun on a fresh cluster then looked like flakiness, and the agent recommended cy.intercept()-based waits that would not have fixed anything. Adds a "Suppressed exception check" to Step 4 pointing at this mechanism and a concrete way to unmask it, plus a guard against calling FLAKY off an incomplete rerun loop. Other lines are wording trims to stay under skillsaw's 6,000-token budget; verified with `skillsaw lint` (0 errors). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

CodeRabbit review on PR openshift#85649: "A failure in even 1 of 4 runs is FLAKY -> Step 5c" sent the agent straight to the fix step, bypassing Step 4 entirely -- including the suppressed-exception check just added there. That defeats the point of the check: the real incident this skill update targets was exactly a rerun-loop result being called FLAKY without ever checking for a swallowed crash. Route through Step 4 first; only classify FLAKY if it finds no other explanation. Also trims a few more words elsewhere to stay within skillsaw's 6,000-token budget after the addition; re-verified with `skillsaw lint` (0 errors).

The completed qe-agent-analysis.md from build 2100954650738954240 self-reported two operational gaps in Step 0b, both directly hit during that run (confirmed from its command audit log): - Operator installs/OperatorGroups: the skill assumed "already installed by the original run", but the suite's after() hook had actually deleted COO/OTel/Tempo, so the agent had to install them via CLI before it could rerun anything. - Cypress binary: npx cypress version succeeded while the binary only existed at /root/.cache/Cypress/, not $CYPRESS_CACHE_FOLDER (/tmp/Cypress); the agent had to discover and copy it manually. Both are pod-image/environment facts that will recur on every run, not one-off flakiness, so they're worth encoding directly rather than re-discovering each time. Left out the agent's third suggestion (Bash timeout margin) since the skill already tells the agent to use run_in_background for reruns -- that recommendation didn't point at a real gap. A few more wording trims elsewhere to stay under skillsaw's 6,000-token budget; verified with `skillsaw lint` (0 errors). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Two of the review's actionable comments were valid: - Preserve the step script's branch when cloning. Verified against the real script (distributed-tracing-tests-tracing-ui-upstream- commands.sh:198): it clones with `--branch main --single-branch` deliberately, into a separate directory from the PR-under-test's own pre-populated checkout, because the e2e specs are meant to run from main regardless of what the PR under test changes. The skill's adaptation row dropped that pin; restored it. - Check CSV readiness, not just presence, before skipping operator install. Existence alone doesn't rule out a Failed or Terminating CSV -- which after() (already known to delete operators, per the prior commit) could plausibly leave behind instead of a clean absence. Now requires phase Succeeded. Left out the finding's other half -- verifying the htpasswd secret "contains the expected data": the credentials are freshly randomized every run (tr < /dev/urandom), so there's no fixed "expected data" to check, and a broken login surfaces immediately as a `before` hook failure Step 4 already diagnoses. More wording trims to stay under skillsaw's 6,000-token budget; verified with `skillsaw lint` (0 errors). Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

…SS_* vars Both actionable comments were valid, and both are pre-existing gaps (not introduced by this branch) surfaced because this PR happened to touch the same lines: - The setup script creates `uiauto-htpass-secret` and `uiauto-htpasswd-idp` (verified: distributed-tracing-tests- tracing-ui-upstream-commands.sh:139-140), not the generic `htpass-secret` the table checked for. That guard would always report the secret missing and recreate it every time. - Step 3's rerun command ran in "a fresh shell" per its own comment, but only *said* to re-export CYPRESS_BASE_URL/KUBECONFIG_PATH/ LOGIN_IDP/LOGIN_USERS without showing how, and the Bash tool this agent runs on does not persist shell state between commands (true of this very session, too) -- so a rerun could easily execute without them. Added the literal export lines (matching what the original step script does, and what the one completed qe-agent run actually had to reconstruct by hand) directly into the rerun block. More wording trims across Step 5c/5d/5e and the closing notes to stay under skillsaw's 6,000-token budget; verified with `skillsaw lint` (0 errors).

[REHEARSALNOTIFIER] Note: If this PR includes changes to step registry files ( Interacting with pj-rehearseComment: Once you are satisfied with the results of the rehearsals, comment: |
Two actionable comments this round; one valid, one not:
- Invalid: "export CYPRESS_SKIP_TESTS so Cypress/before() can read
it." Checked the actual test source
(tests/e2e/dt-plugin-tests.cy.ts:35): SKIP_LIGHTSPEED comes from
`Cypress.env('grep')`, which the skill already passes correctly
via `--env grep="${GREP}"`. Cypress never reads CYPRESS_SKIP_TESTS
itself -- it's purely a shell-side value folded into GREP. Adding
export would be a no-op; skipped.
- Valid: the "Namespace restriction" bullet said to fetch
all-namespaces output and filter kube-system out "before
analysis" -- which still executes the request against kube-system
first. This is exactly what the one completed qe-agent run did in
practice (`oc get csv -A ... | grep -v kube-system`, visible in
its own command log), contradicting the bullet's own "MUST NOT
access" opening sentence. Replaced the guidance with what the
skill's own COO diagnostics already do correctly elsewhere: scope
by namespace or a label selector that structurally excludes
kube-system, never -A piped to grep.
More wording trims to close out under skillsaw's 6,000-token budget;
verified with `skillsaw lint` (0 errors).

Summary
The
tracing-uiskill (ci-operator/step-registry/openshift-observability/qe-agent/resources/skills/tracing-ui/SKILL.md) used by theopenshift-observability-qe-agentstep misdiagnosed a real product bug asFLAKYwhen it ran against openshift/distributed-tracing-console-plugin#306.Root cause of the underlying test failure (now fixed in openshift/distributed-tracing-console-plugin#314): Tempo's
/api/searchomits thetracesfield on zero-match queries, and@perses-dev/tempo-plugin's response parser crashes on the missing field (TypeError: Cannot read properties of undefined (reading 'map')).The QE agent's completed run (
qe-agent-analysis.mdfrom build2100954650738954240) diagnosed this asFLAKY, attributing it to acy.wait(3000)timing race / CodeMirror React state lag, and recommendedcy.intercept()-based test waits. That fix would not have addressed anything, because the test's owntests/cypress/support/e2e.jsregisters aCypress.on('uncaught:exception', ...)handler that explicitly swallows this exact crash signature ('Cannot read prop','undefined is not a function', etc.) instead of failing the test. So the crash never surfaces as a Cypress exception — it just times out waiting for an element that never renders, with the real error logged only to the browser console (neverqe-agent-commands.log/build-log.txt/the JUnit XML). A single clean rerun on a fresh cluster then looks like flakiness even though the trigger is backend response shape, not client timing.Change
Adds a "Suppressed exception check" subsection to Step 4 of the skill, documenting this mechanism and how to unmask it (re-run with the exception filter branch commented out, or diff the raw API response against what the frontend expects), plus a one-line guard against asserting
FLAKYoff an incomplete rerun loop. A few other lines are wording trims (comments, redundant phrasing) needed to stay under skillsaw's 6,000-tokencontext-budgetlimit after the addition.Testing
