Building a tool library is easy. Building a maintainable, secure, and scalable one requires following proven best practices from production systems.
Interactive: Best Practices Checklist
Check off practices you're implementing (0/12)
Discovery
Document all tool schemas clearly
Agents need to understand parameters and return types
Provide search/filter capabilities
Help agents find relevant tools quickly
Versioning
Use semantic versioning (v1.2.3)
Track breaking changes vs minor updates
Deprecate tools gradually, not immediately
Give time to migrate to new versions
Security
Implement rate limiting per tool
Prevent abuse and manage costs
Validate all tool inputs
Prevent injection attacks and errors
Use API keys for authentication
Track usage and control access
Monitoring
Log every tool invocation
Essential for debugging and optimization
Track success/failure rates
Identify problematic tools early
Measure execution time
Optimize performance bottlenecks
Organization
Group tools by category
Easier to navigate and discover
Maintain a changelog
Track what changed and when
Anti-Patterns to Avoid
❌ Tool Sprawl
100+ similar tools with no organization
Problem:
Agents can't find the right tool
Solution:
Consolidate similar tools, use clear naming
❌ Version Hell
Breaking changes without version bumps
Problem:
Agents break unexpectedly
Solution:
Follow semantic versioning strictly
❌ No Documentation
Tools registered without descriptions
Problem:
Agents misuse tools
Solution:
Require docs for every tool
❌ Silent Failures
Tools fail without logging
Problem:
Impossible to debug issues
Solution:
Log all errors with context
Production Readiness
Before deploying your tool library to production:
✓All tools have clear documentation and examples
✓Semantic versioning is enforced
✓Rate limiting is configured for all tools
✓Logging and monitoring are in place
✓Input validation prevents security issues
✓Backup and recovery procedures tested
✓Team training on tool discovery and usage
