- Common failure modes and how to avoid them
Autonomous Coding Assistants
Modern AI coding tools like Claude Code, Cursor, and Devin use multi-agent architectures under the hood. A planner agent breaks down the task. A coder agent writes the implementation. A reviewer agent checks for bugs and style. A test agent runs and validates the code.
Architecture: Hub-spoke with the planner as orchestrator. Pipeline elements within each subtask.
What works: The review agent catches bugs the coder introduces. The separation between planning and coding prevents the system from diving into implementation before understanding the problem.
What breaks: The planner sometimes misunderstands the codebase scope, sending the coder down the wrong path. Context management across large codebases remains the hardest problem.
Customer Support Orchestration
Enterprise support systems use agent teams to handle ticket intake, routing, response generation, and escalation. A triage agent classifies the issue. A knowledge agent searches documentation. A response agent drafts the reply. A sentiment agent monitors customer frustration and triggers escalation to a human when needed.
Architecture: Hub-spoke with exception-based human oversight.
What works: Response times drop from hours to seconds. The knowledge agent ensures answers are grounded in actual documentation, not hallucinated.
What breaks: Edge cases that don't fit any known category get misrouted. The sentiment agent sometimes misreads sarcasm as satisfaction.
Research and Analysis Swarms
Investment firms and consulting companies deploy research swarms that analyze market data, news feeds, financial reports, and social media simultaneously. Multiple research agents explore different angles in parallel. A synthesis agent aggregates findings. A fact-check agent validates claims against primary sources.
Architecture: Swarm with a synthesis hub. Parallel research agents feed into a centralized analysis pipeline.
What works: The breadth of research far exceeds what any single agent (or human analyst) could cover. The fact-check agent catches hallucinated statistics before they reach the final report.
What breaks: Information overload — the synthesis agent struggles when too many research agents produce conflicting findings. Diminishing returns after 4-5 parallel researchers.
What Every Successful System Has in Common
1. Clear separation of concerns. Every agent has one job. No agent tries to do everything.
2. A verification layer. Some agent's job is specifically to check the work of other agents. Quality doesn't emerge — it's engineered.
3. Graceful degradation. When one agent fails, the system continues with reduced capability rather than crashing entirely.
4. Comprehensive logging. Every agent action is recorded. Debugging is possible because the audit trail is complete.
