What its author says it does

Copied from the file, not written here

Use when debugging bugs, failures, broken behavior, flaky tests, regressions, crashes, or performance issues. Build a reproducible feedback loop before hypothesizing or fixing; useful when the user says debug, diagnose, failing, broken, cannot use, slow, or error.

Repro First

中文核心：先复现，再修。不要猜。

Workflow

Build a feedback loop.
- Prefer failing test, curl/HTTP script, CLI repro, Playwright script, trace replay, or minimal harness.
- The loop must produce a clear pass/fail signal.
Reproduce the user-visible failure.
- Confirm the symptom matches what the user reported.
- Capture exact error, output, timing, request, DOM state, or log.
Create 3-5 ranked hypotheses.
- Each hypothesis must be falsifiable.
- Format: if X is the cause, then changing or observing Y will prove or disprove it.
Instrument narrowly.
- One variable at a time.
- Use targeted logs, breakpoints, assertions, or probes.
- Prefix temporary logs with [DEBUG-repro-first] and remove them before finishing.
Fix with regression protection.
- If a correct seam exists, write the failing regression test before the fix.
- If no correct seam exists, document that the architecture blocks reliable regression coverage.
Verify.
- Re-run original repro.
- Re-run relevant tests.
- Remove temporary artifacts.
