# Performance Optimization
|
||
|
|
|
||
|
|
## Model Selection Strategy
|
||
|
|
|
||
|
|
**Haiku 4.5** (90% of Sonnet capability, 3x cost savings):
|
||
|
|
- Lightweight agents with frequent invocation
|
||
|
|
- Pair programming and code generation
|
||
|
|
- Worker agents in multi-agent systems
|
||
|
|
|
||
|
|
**Sonnet 4.5** (Best coding model):
|
||
|
|
- Main development work
|
||
|
|
- Orchestrating multi-agent workflows
|
||
|
|
- Complex coding tasks
|
||
|
|
|
||
|
|
**Opus 4.5** (Deepest reasoning):
|
||
|
|
- Complex architectural decisions
|
||
|
|
- Maximum reasoning requirements
|
||
|
|
- Research and analysis tasks
|
||
|
|
|
||
|
|
## Context Window Management
|
||
|
|
|
||
|
|
Avoid last 20% of context window for:
|
||
|
|
- Large-scale refactoring
|
||
|
|
- Feature implementation spanning multiple files
|
||
|
|
- Debugging complex interactions
|
||
|
|
|
||
|
|
Lower context sensitivity tasks:
|
||
|
|
- Single-file edits
|
||
|
|
- Independent utility creation
|
||
|
|
- Documentation updates
|
||
|
|
- Simple bug fixes
|
||
|
|
|
||
|
|
## Ultrathink + Plan Mode
|
||
|
|
|
||
|
|
For complex tasks requiring deep reasoning:
|
||
|
|
1. Use `ultrathink` for enhanced thinking
|
||
|
|
2. Enable **Plan Mode** for structured approach
|
||
|
|
3. "Rev the engine" with multiple critique rounds
|
||
|
|
4. Use split role sub-agents for diverse analysis
|
||
|
|
|
||
|
|
## Build Troubleshooting
|
||
|
|
|
||
|
|
If build fails:
|
||
|
|
1. Use **build-error-resolver** agent
|
||
|
|
2. Analyze error messages
|
||
|
|
3. Fix incrementally
|
||
|
|
4. Verify after each fix
