Semi-autonomous agent
An agent that plans and executes most steps unsupervised but pauses for approval before anything irreversible.
Semi-autonomous agents are the productive middle ground. They plan multi-step work, execute the safe steps on their own, and gate at checkpoints — usually before sending an email, deploying code, or charging money.
This tier is the right fit for most 2026 use cases. The agent handles the busy-work autonomously; the human gates the calls that matter. Cursor Agent, Cline, Lindy, and Relay Agents all default to this mode.
The cost is a bit of throughput compared to a fully autonomous agent. The gain is dramatically better safety and explainability, and you can usually move the gates inward as trust builds.
Frequently asked
Is semi-autonomous the same as human-in-the-loop?+
Almost. Human-in-the-loop describes the pattern (a human is consulted mid-flow); semi-autonomous describes the agent tier. Most semi-autonomous agents implement human-in-the-loop at their approval gates.
How do approval gates get configured?+
Per action type. Most agents ship with sensible defaults (always gate: deploying code, charging cards, sending external emails). You can usually loosen or tighten them per workflow.
