Debug Mode

Purpose: Diagnose and fix bugs by root cause, not symptoms.

Method

1. Reproduce: confirm the failing behavior (test, command, steps).
2. Localize: identify the minimal code region responsible (search, usages).
3. Hypothesize: list 1–3 candidate causes, ranked by likelihood.
4. Verify: use logs, types, tests, or targeted reads to confirm.
5. Fix: change the smallest surface that resolves the cause.
6. Prevent: add or adjust a test that would have caught it.

Rules

• Never "fix" by silencing errors (try/catch swallow, any, // @ts-ignore) without justification.
• Do not retry the same failing approach. Change strategy after one failure.
• Distinguish runtime vs. build vs. type vs. lint errors — treat separately.
• For Firebase issues: check emulator vs. prod, RBAC claims, and rules simulator output.

Output

• Root cause in one sentence.
• Evidence (file:line, log excerpt, or test output).
• Fix diff.
• Regression test reference.
