5-Step Root-Cause Method
1. CAPTURE → Collect the full error, reproduce, define expected vs actual
2. ISOLATE → Narrow to the smallest failing case
3. HYPOTHESIZE → List and rank likely causes
4. INVESTIGATE → Test hypotheses, inspect state
5. FIX & VERIFY → Apply the minimal fix, confirm, prevent recurrence
Step 1: Capture
- Collect the complete error message and stack trace
- Can reproduce the issue with clear steps
- Identify the input that triggered the error
- Know expected vs actual behavior
Step 2: Isolate
- Identify the failure location from the stack trace
- Which file(s) and function(s) are involved?
- When did it start? (
git bisect,git log) - Narrow down to the smallest reproducible case
Step 3: Hypothesize
- List possible causes based on evidence
- Rank hypotheses by likelihood
- Design a test to confirm or eliminate each
Step 4: Investigate
- Analyze error messages and logs carefully
- Add strategic debug logging; inspect variable state at key points
- Check for: null/undefined values, type mismatches, race conditions, resource exhaustion, external service failures
Common Bug Patterns
| Pattern | Signs | Common Fix |
|---|---|---|
| Null/Undefined | Cannot read property of undefined | Add null checks / optional chaining |
| Off-by-one | Loop runs one too many/few times | Check loop bounds |
| Race condition | Intermittent failures | Add synchronization |
| Type coercion | "1" + 1 = "11" | Explicit type conversion |
| Async issues | Promise { <pending> } | Await/handle promises |
By language and domain:
- JavaScript/TypeScript:
undefined is not a function(binding),Cannot read property of null(optional chaining), promise rejections (async/await handling), type errors (strict mode) - Python:
AttributeError(init/typos),TypeError(type validation),ImportError(paths, circular imports),KeyError(dict defaults) - Database: connection timeouts (pool exhaustion), constraint violations (validation, foreign keys), deadlocks (transaction ordering)
- API/Network: 4xx (request validation, auth), 5xx (server-side, resource limits), timeouts (network, long-running queries)
Investigation Tools
# Search for error message
grep -r "error message" src/
# Find recent changes
git log --oneline -20
git diff HEAD~5
# Check specific function
grep -r "functionName" src/
Step 5: Fix & Verify
Apply the solution:
- Make the minimal change; don't refactor while fixing; one fix per commit
Confirm the fix:
- Original issue is resolved
- No new issues introduced
- Tests pass; add a test to prevent recurrence
- Manual verification done

## 5-Step Root-Cause Method
```
1. CAPTURE → Collect the full error, reproduce, define expected vs actual
2. ISOLATE → Narrow to the smallest failing case
3. HYPOTHESIZE → List and rank likely causes
4. INVESTIGATE → Test hypotheses, inspect state
5. FIX & VERIFY → Apply the minimal fix, confirm, prevent recurrence
```
## Step 1: Capture
- [ ] Collect the complete error message and stack trace
- [ ] Can reproduce the issue with clear steps
- [ ] Identify the input that triggered the error
- [ ] Know expected vs actual behavior
## Step 2: Isolate
- [ ] Identify the failure location from the stack trace
- [ ] Which file(s) and function(s) are involved?
- [ ] When did it start? (`git bisect`, `git log`)
- [ ] Narrow down to the smallest reproducible case
## Step 3: Hypothesize
- [ ] List possible causes based on evidence
- [ ] Rank hypotheses by likelihood
- [ ] Design a test to confirm or eliminate each
## Step 4: Investigate
- Analyze error messages and logs carefully
- Add strategic debug logging; inspect variable state at key points
- Check for: null/undefined values, type mismatches, race conditions, resource exhaustion, external service failures
### Common Bug Patterns
| Pattern | Signs | Common Fix |
|---------|-------|------------|
| Null/Undefined | `Cannot read property of undefined` | Add null checks / optional chaining |
| Off-by-one | Loop runs one too many/few times | Check loop bounds |
| Race condition | Intermittent failures | Add synchronization |
| Type coercion | `"1" + 1 = "11"` | Explicit type conversion |
| Async issues | `Promise { <pending> }` | Await/handle promises |
By language and domain:
- **JavaScript/TypeScript**: `undefined is not a function` (binding), `Cannot read property of null` (optional chaining), promise rejections (async/await handling), type errors (strict mode)
- **Python**: `AttributeError` (init/typos), `TypeError` (type validation), `ImportError` (paths, circular imports), `KeyError` (dict defaults)
- **Database**: connection timeouts (pool exhaustion), constraint violations (validation, foreign keys), deadlocks (transaction ordering)
- **API/Network**: 4xx (request validation, auth), 5xx (server-side, resource limits), timeouts (network, long-running queries)
### Investigation Tools
```bash
# Search for error message
grep -r "error message" src/
# Find recent changes
git log --oneline -20
git diff HEAD~5
# Check specific function
grep -r "functionName" src/
```
## Step 5: Fix & Verify
Apply the solution:
- Make the minimal change; don't refactor while fixing; one fix per commit
Confirm the fix:
- [ ] Original issue is resolved
- [ ] No new issues introduced
- [ ] Tests pass; add a test to prevent recurrence
- [ ] Manual verification done
