Understanding long-running agents
Long-running agent work is a sequence of tool use, decisions and verification over time—not simply a longer answer to a prompt.

A task has a lifecycle
An agent may inspect code, form a plan, edit files, run tests and revise its approach. It can also encounter a permission boundary, a missing requirement or a service failure.
The phrase long-running describes that extended workflow. It does not establish a duration guarantee, unlimited context or an ability to finish without human input.
States worth distinguishing
Execution
The runtime is actively processing the task or using tools.
Waiting
Progress depends on approval, clarification, capacity or another external condition.
Interrupted
Execution or visibility has been disrupted and the state needs to be re-established.
Result returned
The agent has produced an outcome that still needs verification against the original goal.
Persistence and recovery are different
Persistence means relevant state survives beyond a single view or process lifetime. Recovery is the process of establishing what happened and choosing a safe continuation after an interruption.
Blindly replaying the last action can duplicate work. A useful recovery flow first checks the latest history, host state and evidence before deciding whether to resume or restart.
Make a long task easier to supervise
Define the outcome
Give the task a concrete target and specify the boundaries that matter.
Set verification expectations
Name the tests, observations or artifacts that will demonstrate progress.
Leave useful checkpoints
Keep a concise account of what has been established and what remains open.
Review the result
Check the repository and relevant behavior instead of relying on the final message alone.
