If you cannot reproduce, ask for the missing artifact (logs, payload, trace, repro steps, environment) instead of patching on a guess. Ask before adding temporary instrumentation.</li>\n<li>No destructive git (hard reset, clean, force push, checkout over local changes) and no <code>--no-verify</code>.</li>\n<li>Never disable assertions, skip fast tests, lower lint severity, or ignore files to make a check pass or run faster. Clear caches only when a stale cache is the diagnosed cause.</li>\n<li>Fix the requested failure first; ask before expanding to unrelated failures.</li>\n</ul>\n<h2>Outcome</h2>\n<ul>\n<li><strong>Repro</strong>: the fastest reliable failing signal, best a failing test at the behavior seam; otherwise a script, replayed payload, or small harness around the real path. Iterate on the narrowest command and run the broader project gate before reporting; keep coverage, race, browser, and end-to-end modes off the loop unless they are the failing signal.</li>\n<li><strong>Root cause</strong>: traced from the failing boundary to the first bad state or contract mismatch, with evidence (<code>file:line</code>, symptom, tool). For intermittent or unclear bugs, rank 3–5 falsifiable hypotheses and test them one at a time.</li>\n<li><strong>Patch</strong>: the smallest change to the root cause, without adjacent cleanup. If it causes a new failure, diagnose that before touching anything else.</li>\n<li><strong>Regression test</strong> at the seam where the user saw the bug. If only a shallow seam exists, say so rather than adding a fake-confidence helper test.</li>\n<li><strong>Cleanup</strong>: temporary probes, tagged <code>[DEBUG-&lt;id&gt;]</code> while in use, are removed or promoted to real tests.</li>\n<li>Browser-only symptoms go to browser-automation unless a cheaper CLI or unit signal exists.</li>\n<li>If a code-graph tool (GitNexus, codegraph) is installed and fresh, use it to find callers or impact before changing widely used code.</li>\n</ul>\n<p>Done when the original repro passes, the regression test passes (or the missing\nseam is reported), and the relevant build/test/lint checks pass on what you\nchanged, or you name each check that did not run and why.</p>\n<h2>Report</h2>\n<p>Root cause with evidence, changes (<code>path:line — fix</code>), and each check with\npass, fail, or skipped and why. If blocked, name the missing artifact, access,\nor approval.</p>\n<h2>Platform additions</h2>\n<p>No target-specific additions.</p>\n","files":[{"path":"SKILL.md","sizeBytes":3280,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
