Stop-Condition Control Surface

The Stop-Condition Control Surface defines when an agent must suspend action, ask for direction, escalate, or refuse to proceed. A stop condition is a safety mechanism, not a workflow failure.

What question does it answer?

When should the agent have stopped?

What does stop-condition failure look like?

Failures include continuing after a user says stop, acting when source state is missing, proceeding when verification cannot run, crossing into destructive action without confirmation, or providing definitive legal, financial, or health-adjacent guidance when authority or risk is unresolved.

Agent momentum is not authorization. A well-formed workflow treats uncertainty as a state that may require suspension rather than a prompt to improvise.

What evidence should an audit inspect?

What is the decision consequence of a gap?

If no enforceable stop condition governed a material risk, later evidence that the agent encountered uncertainty may establish warning signs without establishing that the workflow could contain them.
