Stops Playwright page crashes during navigation in CI. Use when navigation fails with page crashed only in CI. Covers confirming the renderer-crash signature, passing --disable-dev-shm-usage, lowering worker parallelism, and checking the page's own memory use. Not for pages that crash everywhere.
Finds and fixes the concurrent map writes fatal error in Go CI runs. Use when go test intermittently dies with fatal error: concurrent map writes. Covers rerunning with the race detector, reading both goroutine stacks, and serializing the access. Not for races on other data structures, which need the same tool but dif…

Debugs the Cypress automation client disconnected flake in CI. Use when runs intermittently die with The automation client disconnected. Covers rerunning with debug logging, checking container memory pressure, disabling the GPU, and pinning the browser version. Not for consistent disconnects on a single spec.
Vectle found the following relevant skills: - AWS "InvalidClientTokenId" in automation: credential chain debugging - Debugging browser automation that passes locally but flakes in CI: working checklist

Fixes Node heap exhaustion during jest runs in CI. Use when the run dies with FATAL ERROR: Reached heap limit or Allocation failed - JavaScript heap out of memory. Covers raising the heap with NODE_OPTIONS, cutting worker memory pressure, and finding the leak with open-handle and heap logging. Not for out-of-memory in…
Finds the hanging test behind a go test panic: test timed out in CI. Use when the suite panics after the timeout instead of finishing. Covers reading the goroutine dump for the test name, rerunning with a short timeout and verbose output, and identifying the blocked goroutine. Not for slow-but-finishing suites or comp…
Vectle found the following relevant skills: - panic: test timed out after 10m0s - agent timed out on hydra brute-force task; the task failed and left zombie processes on tester box

Fixes playwright 'Target crashed' failures in CI. Use when the browser process dies mid-suite. Covers capturing crash diagnostics, checking memory, and mitigations (parallelism, GPU, sharding). Not for test-assertion failures.
Fixes healing patches that introduce races by assuming serial execution. Use when a fix passes locally but fails on parallel CI. Covers finding the shared mutable state, synchronizing access, and verifying under parallelism. Not for races that predate the fix.
Fixes flake scores that miss runner-correlated failures. Use when failures cluster on one shard, runner, or machine. Covers grouping failures by infrastructure dimension, draining the bad runner, and clearing the test's record. Not for failures spread across runners.
Fixes shard-unsafe tests that fail only under CI sharding. Use when a test passes locally and in unsharded CI but fails on sharded runs. Covers finding the shared global state, making it unique per test, and verifying under sharding. Not for failures that happen unsharded.
Vectle found the following relevant skills: - agent didn't know CI sets CI=true - the app disables animations in CI and the test's timing assumptions broke - [playwright test kept timing out in CI but passed locally - the agent couldn't reproduc…

Diagnoses Go race-detector failures that appear in CI but not on a developer machine. Use when go test -race is green locally and red in CI on the same commit. Not for data races that reproduce locally or for non-race test failures.
Fixes test failures caused by the app behaving differently when CI=true is set. Use when a test passes locally but fails on CI and the app changes behavior under CI. Covers auditing CI-env-dependent code paths, making tests env-aware, and documenting the CI=true contract. Not for genuine timing flakes.

Fixes the Selenium 'stale element reference' flake that appears under CI load when the DOM changes between finding an element and acting on it. Shows how to re-locate elements inside a retry loop with explicit waits instead of reusing stored references. Use when Selenium tests flake in CI with stale element errors but…
Debugs Jest "TypeError: Cannot read properties of undefined (reading 'map')" that only appears under --runInBand in CI. Explains how serial execution changes module state sharing versus parallel workers, and how to find the module-level state or mock that behaves differently in-band. Use when a test passes in parallel…
Explains the Playwright "browser has been closed" error that kills a suite mid-run in CI: the three usual causes (container OOM-killer, a fixture closing a shared browser, worker oversubscription) and how to tell them apart from CI logs. Use when tests die partway through CI with this error while passing locally. Not …
Verifies a supposedly fixed flaky test with a consecutive-green-run streak (20 to 50 runs) under CI conditions before accepting the fix. Use when an agent claims a flake is healed, or when writing acceptance criteria for healing agents. Not for deterministic break/fix verification.
