Advanced Tool Combinations
Pattern 1: Comprehensive Analysis
Combine:
- Glob + Grep + Read for codebase analysis
- WebSearch + WebFetch for external research
- Task for complex multi-step investigations
Use When:
- Understanding large codebases
- Researching unfamiliar domains
- Analyzing competitor implementations
Pattern 2: Bulk Operations
Combine:
- Glob + MultiEdit for widespread changes
- Grep + Edit for pattern-based updates
- Bash + TodoWrite for progress tracking
Use When:
- Refactoring across multiple files
- Updating API signatures
- Implementing cross-cutting concerns
Pattern 3: Validation Workflows
Combine:

- Grep + WebSearch for error resolution
- Edit + Bash for iterative fixes
Use When:
- Debugging complex issues
- Validating implementations
- Ensuring quality standards
Tool Usage Best Practices
1. Efficiency Guidelines
- Batch Operations: Use MultiEdit over multiple Edit calls
- Parallel Execution: Run multiple Bash commands in single tool call
- Smart Search: Use Glob/Grep before extensive Read operations
- Caching: Leverage WebFetch cache for repeated URL access
2. Error Handling
- Validation: Always validate file existence before Edit
- Backups: Use git (via Bash) before major changes
- Timeouts: Set appropriate timeouts for long-running Bash commands
- Fallbacks: Have alternative approaches for tool failures
3. Context Management
- TodoWrite: Track progress for complex multi-step tasks
- Read Selectively: Use offset/limit for large files
- State Tracking: Maintain context between tool operations
- Documentation: Comment on why specific tools were chosen
4. Security Considerations
- Input Validation: Sanitize inputs for Bash commands
- Path Safety: Use absolute paths for file operations
- Sensitive Data: Never log credentials or secrets
- Web Safety: Validate URLs before WebFetch operations
