Agents are most valuable when tasks require multiple steps, external data or actions, adaptive decision-making, or all three. The overhead of the agent loop is justified when a single LLM call cannot complete the task.
Software engineering — Read bug reports, navigate codebases, write fixes, run tests, fix failures, iterate. Automated bug fixing, code review, documentation generation, test writing, and refactoring at scale.
Research and synthesis — Search sources, read, extract key information, cross-reference, and synthesize. Competitive intelligence, literature review, due diligence, market research.
Data analysis — Write and execute SQL or Python, observe results, refine queries, produce reports. Business analytics, anomaly detection, financial analysis, scientific data exploration.
Customer operations — Look up accounts, check order status, issue refunds, create tickets, send confirmations — all within a single automated interaction. Support automation, order management, document processing.
Personal productivity — Draft emails, schedule meetings, synthesize documents into briefings, manage tasks, coordinate information across tools (calendar, email, notes, project management).
Task has multiple dependent steps. Requires external data or actions. Benefits from adaptive decision-making. Can tolerate the latency and cost of multi-step LLM execution.
Task is single-turn (chatbot is faster and cheaper). Task is deterministic and well-specified (traditional automation is more reliable). Real-time latency is required (agent loop is too slow).
