# Go Debug For non-Tier-1 bugs. If the bug is on a Tier 1 path, switch to `go-tdd-bugfix` — full ceremony required. ## Workflow 1. Capture the exact failure (error message, stack trace, log lines). 2. Identify reproduction command. 3. Read the failing test/log/error verbatim. 4. Trace the execution path. 5. Form one primary hypothesis. 6. Make the smallest fix. 7. Verify with targeted test. 8. Run broader verification (`go test -race ./...`). 9. Add regression test if missing. 10. Explain root cause, not only the patch. ## Forbidden - Suppressing errors. - Weakening tests to pass. - Adding retries/sleeps unless root cause is timing. - Broad refactors during debugging. - "While I was in there, I also refactored…" ## Anti-patterns to avoid - Fixing the symptom without understanding the root cause. - "I added a try/catch to handle it silently" (hides the bug for next time). - "I updated the test to match the new behavior" (never weaken an assertion to pass a test — if the test fails, the bug is real).
