This skill focuses on <code>browser_network_requests</code> — not just “any 500s” but patterns that indicate bugs, waste, or security issues.</p>\n<h2>How it works</h2>\n<ol>\n<li>Drive the app in the browser (navigate, click, submit forms) so real requests fire.</li>\n<li>Call <strong><code>browser_network_requests</code></strong> after meaningful interactions (and after navigation settles).</li>\n<li>Classify and report findings using the criteria below.</li>\n</ol>\n<p>Follow <code>cursor-ide-browser</code> workflow rules: use <code>browser_snapshot</code> before structural interactions; after actions that change the page, take a fresh snapshot before the next interaction.</p>\n<h2>Audit checklist</h2>\n<h3>Failures</h3>\n<ul>\n<li><strong>4xx / 5xx</strong> — list method, URL (path + query), status, and whether the UI handled the error.</li>\n<li><strong>CORS or network errors</strong> — often misconfigured origins or mixed content.</li>\n</ul>\n<h3>Performance</h3>\n<ul>\n<li><strong>Slow requests</strong> — flag requests with high latency (e.g. &gt; 500 ms server time if timings are visible; otherwise note unusually large waterfalls).</li>\n<li><strong>Duplicate calls</strong> — same URL + method fired multiple times in one user action (often a React effect or missing deduplication).</li>\n<li><strong>Oversized payloads</strong> — responses that look huge for what the UI needs (suggest pagination, field selection, or compression).</li>\n</ul>\n<h3>Security and privacy</h3>\n<ul>\n<li><strong>Sensitive data in URLs</strong> — tokens or PII in query strings.</li>\n<li><strong>Missing auth</strong> — API calls that should send credentials or bearer tokens but do not (compare with adjacent authenticated calls).</li>\n</ul>\n<h3>Correctness</h3>\n<ul>\n<li><strong>Unexpected hosts</strong> — calls to third parties not documented for the feature (trackers, accidental leaks).</li>\n<li><strong>Preflight storms</strong> — excessive OPTIONS requests may indicate wrong CORS caching or too many distinct origins.</li>\n</ul>\n<h2>Steps</h2>\n<ol>\n<li><p><strong>Start from a clean navigation</strong> — <code>browser_navigate</code> to the target URL (or use an existing tab via <code>browser_tabs</code>).</p>\n</li>\n<li><p><strong>Exercise the feature</strong> — interactions that trigger API usage (filters, infinite scroll, form save, modal open).</p>\n</li>\n<li><p><strong>Fetch network log</strong> — <code>browser_network_requests</code> after each logical step if the page does multiple round-trips.</p>\n</li>\n<li><p><strong>Report</strong> — structured output:</p>\n<ul>\n<li>Summary counts (failed, slow, duplicate groups).</li>\n<li>Table or bullet list of issues with <strong>URL pattern</strong> (not necessarily full secrets), <strong>status</strong>, <strong>category</strong> (failure / perf / security / correctness).</li>\n<li>Recommended next code changes or investigations.</li>\n</ul>\n</li>\n</ol>\n<h2>Notes</h2>\n<ul>\n<li>Iframe traffic may not appear in the same log — note if the feature runs inside an iframe.</li>\n<li>Compare against <strong>expected</strong> API design; a 404 might be correct for “optional resource not found” if handled in UI.</li>\n<li>Pair with <code>browser_console_messages</code> for errors that do not surface as failed HTTP (e.g. parse errors after 200).</li>\n</ul>\n","files":[{"path":"SKILL.md","sizeBytes":3149,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
