# Performance Optimization why-not-tooled: context-window and plan-mode choices are session judgment; no linter sees them. ## 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 ## Extended Thinking + Plan Mode Extended thinking is enabled by default, reserving up to 31,999 tokens for internal reasoning. Control extended thinking via: - **Toggle**: Option+T (macOS) / Alt+T (Windows/Linux) - **Config**: Set `alwaysThinkingEnabled` in `~/.claude/settings.json` - **Budget cap**: `export MAX_THINKING_TOKENS=10000` - **Verbose mode**: Ctrl+O to see thinking output For complex tasks requiring deep reasoning: 1. Ensure extended thinking is enabled (on by default) 2. Enable **Plan Mode** for structured approach 3. Use multiple critique rounds for thorough analysis 4. Use split role sub-agents for diverse perspectives ## Build Troubleshooting If build fails: 1. Use **build-error-resolver** agent 2. Analyze error messages 3. Fix incrementally 4. Verify after each fix
