Approche de débogage

model: claude-sonnet-4-0

Debug complex issues using specialized debugging agents:

[Extended thinking: This tool command leverages the debugger agent with additional support from performance-engineer when performance issues are involved. It provides deep debugging capabilities with root cause analysis.]

Debugging Approach

1. Primary Debug Analysis

Use Task tool with subagent_type="debugger" to:

• Analyze error messages and stack traces
• Identify code paths leading to the issue
• Reproduce the problem systematically
• Isolate the root cause
• Suggest multiple fix approaches

Prompt: "Debug issue: $ARGUMENTS. Provide detailed analysis including:

1. Error reproduction steps
2. Root cause identification
3. Code flow analysis leading to the error
4. Multiple solution approaches with trade-offs
5. Recommended fix with implementation details"

2. Performance Debugging (if performance-related)

If the issue involves performance problems, also use Task tool with subagent_type="performance-engineer" to:

• Profile code execution
• Identify bottlenecks
• Analyze resource usage
• Suggest optimization strategies

Prompt: "Profile and debug performance issue: $ARGUMENTS. Include:

1. Performance metrics and profiling data
2. Bottleneck identification
3. Resource usage analysis
4. Optimization recommendations
5. Before/after performance projections"
