Compromises
- Inconsistent states with insufficient consistency strategy.
- Security risks from autonomous entities with extensive privileges.
- Organizational uncertainty when responsibilities become fragmented.
- Define explicit contracts (schemas) between agents.
- Build observation and distributed tracing paths from the start.
- Implement conflict resolution and compensation as primitive patterns.

Description
Agent-based workflows describe a paradigm where autonomous, context-aware agents coordinate tasks, make decisions and execute process steps. They combine distributed orchestration, event-driven communication and local state management to enable dynamic, scalable automation. Use cases span integration scenarios, adaptive business processes and decentralized automation.
✔Benefits
- Improved scalability through distributed execution and local decision logic.
- Increased resilience since parts can operate independently and fail in isolation.
- More flexible adaptation to context changes via autonomous agents.
✖Limitations
- More complex debugging and monitoring of distributed agents.
- Higher design and coordination effort for agent protocols.
- Not optimal for strongly sequential, transactional flows without local autonomy.
Trade-offs
Metrics
- Mean decision latency
Time between event arrival and completed agent decision.
- Error rate per agent type
Share of failed tasks per agent category.
- Conflict resolution time
Average time to resolve conflicting agent decisions.
Examples & implementations
Logistics route optimization with agents
Decentralized agents optimize delivery routes based on traffic data and vehicle availability, reduce empty miles and react locally to disruptions.
Banking compliance with contextual agents
Agents continuously evaluate transactions against compliance rules and escalate suspicious patterns for manual review.
Cloud onboarding via agents
Agents perform configuration checks, roll out infrastructure and validate security policies during onboarding processes.
Implementation steps
Analyze context and define agent roles and responsibilities.
Design event schemas, contractual interfaces and error strategies.
Incremental rollout with pilot agents, monitoring and iterative expansion.
⚠️ Technical debt & bottlenecks
Technical debt
- Ad hoc agent protocols without versioning and documentation.
- Missing observability standards that hinder debugging.
- Incompatible event schemas between services over time.
Known bottlenecks
Misuse examples
- Using for strictly transactional, synchronously chained processes without suitable consistency mechanisms.
- Agents given direct writes to central databases without coordination.
- Oversized number of heterogeneous agent types without governance or versioning.
Typical traps
- Underestimating test effort for non-deterministic behavior.
- Lack of event schema standardization leads to integration chaos.
- Distributing complex state machines too early before stabilizing rules.
