| 1 | # Seeker — Find Bugs from Production |
| 2 | |
| 3 | Pull logs from pods, analyze, raise issues on GitHub. |
| 4 | |
| 5 | ## Process |
| 6 | |
| 7 | 1. **Pull logs** from all pods in the namespace: |
| 8 | ``` |
| 9 | kubectl logs --all-containers --since=1h -l app=<app> --tail=500 |
| 10 | ``` |
| 11 | If kubectl not available, check for log files in common locations: |
| 12 | - `/var/log/`, `~/.pm2/logs/`, `docker logs` |
| 13 | - Cloud: `gcloud logging read`, `aws logs`, `fly logs` |
| 14 | |
| 15 | 2. **Analyze** each log stream for: |
| 16 | - Unhandled exceptions / stack traces |
| 17 | - Error-level log lines (ERROR, FATAL, CRITICAL, panic, segfault) |
| 18 | - OOM kills, restart loops, crash backoffs |
| 19 | - Slow queries (>1s), timeout errors |
| 20 | - 5xx HTTP responses, connection refused |
| 21 | - Auth failures, rate limit hits |
| 22 | - Memory/CPU warnings |
| 23 | |
| 24 | 3. **Deduplicate** — group similar errors by stack trace signature. Don't create 10 issues for the same NullPointerException. |
| 25 | |
| 26 | 4. **Raise GitHub issues** for each unique bug: |
| 27 | ``` |
| 28 | gh issue create \ |
| 29 | --title "[seeker] <error type>: <brief description>" \ |
| 30 | --body "<structured body>" \ |
| 31 | --label "bug,seeker" |
| 32 | ``` |
| 33 | |
| 34 | Issue body format: |
| 35 | ```markdown |
| 36 | ## Source |
| 37 | Pod: <pod-name> | Container: <container> | Time: <timestamp> |
| 38 | |
| 39 | ## Error |
| 40 | <exact error message / stack trace> |
| 41 | |
| 42 | ## Frequency |
| 43 | <N occurrences in last hour> |
| 44 | |
| 45 | ## Impact |
| 46 | <what's affected — users, API, jobs> |
| 47 | |
| 48 | ## Suggested Fix |
| 49 | <initial diagnosis + suggested approach> |
| 50 | ``` |
| 51 | |
| 52 | 5. **Verify old fixes** — check if previously raised issues are now fixed in production: |
| 53 | ``` |
| 54 | gh issue list --label seeker --state open |
| 55 | ``` |
| 56 | For each open issue: |
| 57 | - Search current logs for the same error signature |
| 58 | - If error NO LONGER appears in logs → the fix was deployed and worked: |
| 59 | ``` |
| 60 | gh issue close <number> --comment "✅ Verified fixed in production — error no longer appears in pod logs (checked $(date -u +%Y-%m-%dT%H:%M:%SZ))" |
| 61 | ``` |
| 62 | - If error STILL appears → leave open, add comment with latest occurrence |
| 63 | |
| 64 | 6. **Report** summary: N logs scanned, M unique errors found, K issues created, J issues auto-closed (verified fixed). |
| 65 | |
| 66 | ## Rules |
| 67 | - Only create issues for REAL bugs — not info/debug noise |
| 68 | - Check existing open issues before creating duplicates: `gh issue list --label seeker` |
| 69 | - Include enough context to reproduce (pod, timestamp, full trace) |
| 70 | - Tag severity: critical (service down), high (errors spiking), medium (intermittent), low (warning) |
| 71 | - Auto-close issues whose errors no longer appear in production logs |
| 72 | |
| 73 | ## Parallelism — MANDATORY |
| 74 | |
| 75 | - **Multiple namespaces / apps**: pull logs in parallel — batch all `kubectl logs` commands across pods/containers in ONE message, not one-by-one. |
| 76 | - **Multiple log sources**: `kubectl`, `gcloud logging`, `docker logs`, file paths → fire all reads concurrently in one message. |
| 77 | - **Issue creation**: when raising N issues, batch the `gh issue create` calls in one message so they go out concurrently. |
| 78 | - **Verification pass**: when checking which open issues are now resolved, run all `gh issue list` + log-grep commands in parallel batches. |
| 79 | - **Heavy log fetches** (>30s, large `--tail`): `run_in_background: true`, scan other sources while it streams. |
| 80 | |
| 81 | Sequential tool calls for independent operations is a bug. Default to parallel. |
