1# Parallel Debugging
2 
3Framework for debugging complex issues using the Analysis of Competing Hypotheses (ACH) methodology with parallel agent investigation.
4 
5## When to Use This Skill
6 
7- Bug has multiple plausible root causes
8- Initial debugging attempts haven't identified the issue
9- Issue spans multiple modules or components
10- Need systematic root cause analysis with evidence
11- Want to avoid confirmation bias in debugging
12 
13## Hypothesis Generation Framework
14 
15Generate hypotheses across 6 failure mode categories:
16 
17### 1. Logic Error
18 
19- Incorrect conditional logic (wrong operator, missing case)
20- Off-by-one errors in loops or array access
21- Missing edge case handling
22- Incorrect algorithm implementation
23 
24### 2. Data Issue
25 
26- Invalid or unexpected input data
27- Type mismatch or coercion error
28- Null/undefined/None where value expected
29- Encoding or serialization problem
30- Data truncation or overflow
31 
32### 3. State Problem
33 
34- Race condition between concurrent operations
35- Stale cache returning outdated data
36- Incorrect initialization or default values
37- Unintended mutation of shared state
38- State machine transition error
39 
40### 4. Integration Failure
41 
42- API contract violation (request/response mismatch)
43- Version incompatibility between components
44- Configuration mismatch between environments
45- Missing or incorrect environment variables
46- Network timeout or connection failure
47 
48### 5. Resource Issue
49 
50- Memory leak causing gradual degradation
51- Connection pool exhaustion
