Sweep the whole app and report what is broken
You do not need to understand the codebase to check it. Reticle drives every reachable control in the running app and reports the anomalies. Not installed? RETICLE_INSTALL_SOURCE=npx_skill npx @reticlehq/server@latest init, then the install-and-verify skill.
1. Ask the app what it can do
reticle_run({ tool: "reticle_capabilities", args: { sessionId } })
About 1 KB, and it is the app describing its own testable surface: every registered testid, every domain signal, the stores, and the saved flows with their steps. That beats snapshotting the DOM and inferring intent from element names, and it is the cheapest orientation available.
2. Click everything
reticle_run({ tool: "reticle_verify", sessionId, args: { action: "crawl", maxSteps: 25 } })
{
"interactiveFound": 3,
"stepsRun": 3,
"anomalies": [],
"counts": { "consoleErrors": 0, "failedRequests": 0, "deadControls": 0, "contradictions": 0 },
"visited": ["- textbox \"Email\"", "- button \"Sign in\""],
"truncated": false
}
deadControls and contradictions are the two counts that mean a real problem. Console errors and failed requests are worth reading but a busy app produces both innocently. A dead control is a button wired to nothing; a contradiction is a channel disagreeing with what the screen showed.
It clicks everything, so point it at a dev environment. maxSteps bounds it and defaults to 25. Want a non-destructive pass first: what is reachable, without touching it? reticle_run({ tool: "reticle_explore", sessionId }).
Do not hand-roll this sweep. The obvious version (click each control, assert no console error) passes on exactly the bug you are sweeping for, because a dead button throws nothing.
3. Compare what the API said against what rendered
reticle_run({ tool: "reticle_reconcile", sessionId })
The API returned ten rows, the table shows nine, nothing errored. Neither the network log nor the DOM is wrong on its own. Only the comparison catches it, and nothing else you can run makes that comparison.
4. Find the parts nobody exercised
reticle_run({ tool: "reticle_verify", sessionId, args: { action: "coverage" } }) // { total, exercised, untouched }
And if the project already has saved flows, ask whether they prove anything:
reticle_run({ tool: "reticle_domain", sessionId })
// → { flowCount, coverage: { asserted, presenceOnly, assertionFree }, gaps: { declaredUntestedSignals, … } }
A suite of forty flows where thirty-one assert nothing is a suite that will stay green through any regression. That number is usually the most alarming thing in the whole audit, and nothing else reports it.
5. Report
Lead with the counts, then one line per real finding with its file:line from reticle_look { action: "element" }. Separate:
- Broken: dead controls, contradictions, failed requests, errors thrown during the sweep.
- Unverified:
untouched controls and assertionFree flows. Not known to be broken; known to be unchecked.
- Pre-existing: console errors that were already there before the sweep started. Say so, so nobody attributes them to today's change.
Do not report a clean audit over a partial one. If truncated is true or maxSteps cut the sweep short, say what was not reached. A silent cap reads as "everything is fine" when it means "I stopped".
