Tool Composition Patterns

Orchestrate multiple tools into sophisticated, powerful agent workflows

Parallel Execution: Speed Through Concurrency

When tools don't depend on each other, run them simultaneously. Parallel execution dramatically reduces total execution time by doing multiple things at once.

Instead of waiting for Tool A before starting Tool B, both run together. The agent waits for all to complete before proceeding.

When to Use Parallel Execution

Data Gathering
search_web
query_database
fetch_api
Collect from multiple sources simultaneously
3x faster
Content Generation
generate_text
create_image
fetch_data
Produce different content types at once
2.5x faster
Validation
check_grammar
verify_facts
scan_security
Run multiple checks in parallel
4x faster
Multi-Platform Actions
post_slack
send_email
update_crm
Execute across platforms simultaneously
3.5x faster

Critical Considerations

⚠️
Race Conditions
Avoid tools that modify the same resource
Solution:
Use locks or sequential execution for writes
🔒
Resource Limits
Too many parallel calls can overwhelm APIs
Solution:
Implement rate limiting and batching
🛡️
Error Handling
One failure shouldnt stop all other tools
Solution:
Isolate errors, continue with successful results
🔀
Result Ordering
Results arrive in unpredictable order
Solution:
Label results, dont assume completion order
