| 1 | # Debugger - Systematic Bug Investigation |
| 2 | |
| 3 | Methodical debugging that narrows down root causes before proposing fixes. |
| 4 | |
| 5 | ## Workflow |
| 6 | |
| 7 | ### 1. Reproduce |
| 8 | |
| 9 | - Run the failing test or reproduce the error |
| 10 | - Capture the exact error message, stack trace, and context |
| 11 | - Note: is this a regression (worked before) or new behavior? |
| 12 | |
| 13 | ### 2. Hypothesize |
| 14 | |
| 15 | Generate 2-3 hypotheses ranked by likelihood: |
| 16 | |
| 17 | ```text |
| 18 | Hypothesis 1 (70%): [most likely cause] |
| 19 | Evidence for: [what supports this] |
| 20 | Evidence against: [what contradicts] |
| 21 | Test: [how to verify] |
| 22 | |
| 23 | Hypothesis 2 (20%): [alternative cause] |
| 24 | ... |
| 25 | |
| 26 | Hypothesis 3 (10%): [unlikely but possible] |
| 27 | ... |
| 28 | ``` |
| 29 | |
| 30 | ### 3. Investigate |
| 31 | |
| 32 | Test each hypothesis starting with the most likely: |
| 33 | |
| 34 | - Read relevant code paths |
| 35 | - Check git log for recent changes to affected files |
| 36 | - Search for similar patterns that work correctly |
| 37 | - Add targeted debug output if needed |
| 38 | |
| 39 | ### 4. Root Cause |
| 40 | |
| 41 | Present the confirmed root cause: |
| 42 | |
| 43 | ```text |
| 44 | ROOT CAUSE: [what's actually wrong] |
| 45 | WHERE: [file:line] |
| 46 | WHY: [how it got this way] |
| 47 | SINCE: [when it was introduced, if knowable] |
| 48 | ``` |
| 49 | |
| 50 | ### 5. Fix Proposal |
| 51 | |
| 52 | Propose the minimal fix. Explain why this fix is correct. |
| 53 | |
| 54 | ```text |
| 55 | FIX: [description] |
| 56 | CHANGES: |
| 57 | - file.ts:42 - [what to change] |
| 58 | RISK: [low/medium/high] |
| 59 | TESTS: [how to verify the fix] |
| 60 | ``` |
| 61 | |
| 62 | Wait for approval before implementing. |
| 63 | |
| 64 | ## Rules |
| 65 | |
| 66 | - Never guess. Investigate systematically. |
| 67 | - Never apply fixes without finding root cause first. |
| 68 | - Check the git blame — recent changes are more likely to be the cause. |
| 69 | - Use project memory to recall previous bugs in the same area. |
| 70 | - If stuck after 3 rounds of investigation, escalate to user with findings so far. |
| 71 | - Capture debugging learnings: `[LEARN] Debugging: <insight>` |
| 72 | |
| 73 | ## Anti-Patterns to Avoid |
| 74 | |
| 75 | - "Shotgun debugging" — changing random things hoping something works |
| 76 | - Ignoring stack traces — they tell you exactly where to look |
| 77 | - Not reproducing first — you can't fix what you can't see |
| 78 | - Fixing symptoms instead of root causes |
