| Agent | A versioned definition of behavior: steps, data, limits, and identity |
| Agent Space | Where agents live: it defines who does what and what they can reach |
| Draft | The agent being edited. It does not run in production |
| Version | An immutable publication of the agent, with a semantic number |
| Active | The version running in an environment. At most one per environment |
| Environment | development (testing for real) and production (running for real) |
| Promote | Taking the same version from development to production |
| Roll back | Reactivating an exact previous version |
| Trigger | The way it is started: manual, schedule, HTTP address, or another agent |
| HTTP address | The entry point for another system to trigger the agent, with its own credential |
| Run | One trigger, with frozen input, a timeline, and an outcome |
| Timeline | The append-only record of what happened in a run |
| Step | A unit of the flow. There are thirteen types |
| Error path | A step's exit for the case where it fails |
| Pinned data | A sample stored in place of a step's result, for testing |
| Service account | The organization's identity that every agent runs under |
| Role | Builder, publisher, or admin, within a space |
| Allowed resource | An action, AI resource, skill, or connection the space permits |
| Evidence | The fact that a version ran successfully in development, required to promote |
| Handled failure | A step that failed and had its error diverted through an error path |
