Agent Versions
Agent Versions
Section titled “Agent Versions”Agent versions are saved snapshots of an agent configuration. They let you preserve a known-good prompt, tool, and capability setup while continuing to edit the draft agent.
This feature is gated by FEATURE_AGENT_VERSIONS.
What You Can Do
Section titled “What You Can Do”- Save the current agent draft as a new version.
- Set a default version for normal use.
- Compare authored and resolved configuration between two versions.
- Roll back the editable draft to a previous version.
- Fork a version into a new agent.
- Configure each endpoint to use the Agent default, latest version, or a pinned version.
Runtime Behavior
Section titled “Runtime Behavior”When a session is created, Everruns records the resolved agent_version_id on the session. Events emitted during that session include version metadata so logs, traces, and exports can identify the exact agent configuration that ran.
Endpoints can use:
default: follow the agent default version.latest: always use the newest saved version.pinned: keep using a specific version until changed.
Versions are immutable. Rollback updates the editable draft and saves a new rollback version so history remains append-only.
