1. One browser matcher exceeds 100 columns 📘 Rule violation ⚙ Maintainability
The transient-context regular expression in startChromium() occupies 132 characters on physical line 199. Its three alternatives extend beyond the shared column guide, so later edits cannot follow the file's wrapping convention.
Agent Prompt
## Issue description
The transient Chromium context-error matcher exceeds the required 100-character physical line limit.
## Fix Focus Areas

## Recommended Fix
Replace the long regular-expression alternation with a wrapped representation, such as a multiline array of accepted normalized error messages, while preserving the optional trailing-period behavior.

printWidth: 100 is a formatting target, not a hard maximum. The project has no ESLint max-len rule. This regular-expression literal follows the existing formatter; splitting the pattern solely to enforce a strict column limit is not needed.

Initial review of the complete diff (23 files, 1 commit): a Linux-only, dev-facing smoke harness that loads the built extension into isolated headless Chromium and Firefox and drives the real popup → background → Chat Completions flow against a loopback mock server. No extension runtime, manifest, or API behavior is changed.
- Runner CLI & preflight —
scripts/xvfb-smoke.mjs/scripts/smoke/runner.mjsaddnpm run smokewith browser selection, build-hash recheck, artifact-parent containment, and documented exit codes (2 preflight, 130/143 on signals). - Browser adapters —

mock-server.mjsgates the SSE tail and returns 503;scenarios.mjsasserts popup identity, the partial Unicode answer, the completed answer with exactly one conversation record, and HTTP-error handling. - Tests — 145 unit tests across 8 files plus fake-browser/process fixtures.

Chromium could not be exercised here: full Chromium aborts with FATAL … No usable sandbox! because unprivileged user namespaces are disabled in this environment. That matches the documented prerequisite (the runner deliberately adds no --no-sandbox), so it is environmental rather than a defect.

scripts/smoke/firefox.mjs:249
- These diagnostic requests use the default 30-second WebDriver deadline and run serially. The runner's outer 3-second
bounded()wait does not cancel the underlying Firefox request, so cleanup can overlap an in-flight capture, and a screenshot failure prevents the DOM artifact; use independent short diagnostic/cleanup signals withPromise.allSettledso successful artifacts are retained and capture cannot hold shutdown open.
const screenshot = await command('GET', '/screenshot')
await writeFile(`${destination}.png`, Buffer.from(screenshot, 'base64'))
const source = await command('GET', '/source')
await writeFile(`${destination}.html`, source)
scripts/smoke/runner.mjs:302
- Firefox startup failures cannot produce the promised failure diagnostics here:
activeAdapteris assigned only afterstartFirefox()resolves, so any failure after the session/popup has been created leaves this condition false and skipscapture('failure')entirely. Add a startup-failure capture path inside the Firefox adapter (or expose a partially initialized adapter) before rethrowing, so popup screenshot/DOM artifacts are retained like Chromium's startup path.
if (activeAdapter && !controller.signal.aborted) {
try {
await bounded(activeAdapter.capture('failure'), 3000, 'Failure capture')

Updated transport shutdown and failure diagnostics:
The existing Chromium cancellation path already preserves the original run cancellation through the runner's bounded operation. Startup-only capture and additional hash-collision coverage remain optional diagnostic/coverage extensions. The long regular-expression literal follows the existing formatter configuration; printWidth is not a hard line-length rule. |

Incremental review of bc07d7f (delta against the prior pullfrog review at 3caf2a8). The new commit folds in the transport/cleanup hardening and turns the previously serial Firefox diagnostics into parallel, independently-failing operations.
- CDP close now surfaces transport failures —
scripts/smoke/cdp.mjssnapshots the pendingfailureat cleanup time (closeFailure) and makesclose()reject with it, so an unexpected WebSocketclose/errorwhile the browser is still alive can no longer resolve shutdown as a pass. The lifecycle defer still registers the non-throwingcleanup. - Firefox capture retains partial artifacts —
scripts/smoke/firefox.mjsnow issues the/screenshotand/sourcerequests withPromise.allSettled, writing whichever succeeds and raising anAggregateErrorthat carries every diagnostic failure. - Regression tests added — new cases cover idle-transport
close/errorrejection (including idempotent re-close), DOM retention when the screenshot fails, aggregation of both errors, and cancellation of both pending diagnostics with the run signal.
Validation performed in this run: node --test tests/unit/scripts/smoke-chromium.test.mjs tests/unit/scripts/smoke-firefox.test.mjs → 72 pass, 0 fail.

When this entry is invoked from another directory, such as cd /tmp && npm --prefix /workspace/chatGPTBox run smoke -- ..., npm runs the script with PWD=/workspace/chatGPTBox and exposes /tmp only through INIT_CWD. Consequently, the runner's relative --*-path and --artifacts-dir values resolve against the repository rather than the caller's directory, causing valid executables to be reported missing or artifacts to be written in the wrong place despite the documented caller-relative behavior. Pass or use INIT_CWD as the base directory for the npm entry.
Useful? React with 👍 / 👎.
There was a problem hiding this comment.
The caller-relative wording is too broad for npm invocations. This entry follows npm's package-root working directory. The README now distinguishes direct Node/shell invocation from npm and recommends absolute paths across directories. The runner retains standard npm semantics; it does not reinterpret relative arguments through INIT_CWD.

🔵 Needs a closer look
Scenario cleanup can bypass the bounded cleanup budget, and Firefox timeout documentation does not match the implementation.
Review details
Suppressed comments (2)
scripts/smoke/README.md:134
- The documented timeout bound is broader than the implementation: Firefox session creation uses
timeoutMs: 60000instartFirefox, so not every browser request is capped at 30 seconds. Please document the session-creation exception (or lower that timeout) so users can rely on the stated cleanup/startup bounds.
Startup is limited to 60 seconds, individual browser requests to 30 seconds, the
browser test run to five minutes, and cleanup to ten seconds. Readiness checks
may retry, but session creation, addon installation, and test requests never do.
scripts/smoke/scenarios.mjs:290
- The mock server is closed directly here, so this path bypasses the lifecycle's bounded cleanup budget. If
server.close()remains pending,runScenarios()can block until the outer five-minute smoke-run timeout instead of returning a cleanup failure promptly; wrap this cleanup inbounded(...)(the lifecycle-deferred close remains the fallback).

Three moderate review findings remain in Firefox diagnostics and supervisor start-failure handling.
Review details
Suppressed comments (3)
scripts/smoke/firefox.mjs:252
- The runner bounds the overall failure capture to three seconds, but these WebDriver calls use the default 30-second request timeout and create independent request controllers. If Firefox/geckodriver is unresponsive,
capture()returns after the outer bound while both fetches continue for up to 30 seconds, potentially contending with session cleanup and exhausting its ten-second budget. Add a short diagnostic timeout that aborts the underlying requests when capture is bounded, while retaining the run signal for cancellation.
const screenshot = await command('GET', '/screenshot')
await writeFile(`${destination}.png`, Buffer.from(screenshot, 'base64'))
})(),
(async () => {
const source = await command('GET', '/source')
scripts/smoke/firefox.mjs:267
- Unlike the Chromium adapter, Firefox has no startup-failure capture path. If WebDriver reaches the popup and then addon/navigation/readiness setup fails,
startFirefox()rejects before its returned adapter is assigned toactiveAdapter, so runner-level failure capture is skipped and no Firefox screenshot or DOM is retained even though the popup may already be available. Add a capture-on-error path around the post-session startup steps while preserving the existing deferred session cleanup.
return {
evaluate,
evaluateCleanup,
capture,

scripts/smoke/supervisor.mjs:97
- Node's
ChildProcesscontract allows anexitevent to follow a failedspawn/error. If that sequence occurs, the parent handlesstart-errorfirst (settingended), then treats this follow-uptarget-exitas an invalid supervisor message, marks ownership uncertain, and reports an unnecessary cleanup failure/profile retention for an ordinary executable-start failure. Suppress the follow-up exit after a start error, or make the parent accept that sequence.
target.once('error', (error) =>
send({ type: 'start-error', message: error.message, code: error.code }),

Follow-up to the timeout and scenario-cleanup notes: The README now distinguishes the 10-second CDP and 30-second WebDriver defaults, Firefox's 60-second session-creation exception, the shared five-minute browser loop, and each lifecycle's ten-second waiting budget. The timers are unchanged.
|
|
Follow-up to the Firefox diagnostics and supervisor notes:
|
Load real Chromium and Firefox extensions with isolated profiles and loopback mock requests. Bound cleanup and propagate failure and cancellation through preflight and artifact reads. Use isolated Node supervisors and private control channels for group termination. Never signal a remembered numeric process group from the runner. Preserve profiles on detected ownership loss or when group termination cannot be confirmed. Distinguish target results from supervisor termination. Document that descendants escaping these groups are outside the cleanup guarantee and may outlive profile removal. Install Firefox from a verified per-run build snapshot. Cancel active snapshot transfers and wait for stream closure before rejecting them. Recheck Chromium artifacts before launch and use unambiguous directory hashes that include empty directories. Verify popup identity, streaming, complete outbound history, error reporting, and conversation records returned by the background. Cover process isolation, control-channel failures, signal exit codes, artifact consistency, startup failures, and corrupted conversation context. Keep compatibility entry points and document prerequisites, path resolution, and cleanup limitations.
