Multi-agent systems: when dividing a task makes sense
Dividing work among agents can help when subtasks are distinct. It also adds coordination, cost and failure points. A communication protocol does not grant permissions or prove traceability and security by itself.

Multi-agent systems: when dividing a task makes sense
Dividing work among agents can help when subtasks are distinct. It also adds coordination, cost and failure points. A communication protocol does not grant permissions or prove traceability and security by itself.
Planning a first application
- Define input and output contracts for each subtask.
- Assign minimum tools and permissions to each participant.
- Centralize task state and validate the integrated result.
What to check before deciding
Compare with a simpler workflow using the same tasks. Measure quality, latency, cost and coordination failures. Add agents only when improvement justifies complexity and each action can be attributed.
