One responsibility with a clear result and authority boundary.
StackOS Library / agents
Specialist agents with clear jobs.
Each agent owns one bounded responsibility inside a larger workflow, with its context, tools, output, and handoff made explicit.
Quick answer
What are AI agents for business?
An AI agent is a model operating under a role contract for one bounded responsibility. The contract defines the context and tools it receives, the result it must return, how it recovers, and when control goes back to the orchestrator.
Compare agents, workflows, and orchestrators →Relevant context, tools, acceptance criteria, and recovery.
Returns the result and rationale without taking over the whole workflow.
