# AgentTimelineEntry `agent.timeline-entry@1`

Generated at 2026-11-13 06:25:48 UTC from [`openvibe-contracts v0.419.0`](https://github.com/OpenVibers/OpenVibe.Contracts/tree/v0.419.0) and [`openvibe-sdk v0.161.0`](https://github.com/OpenVibers/OpenVibe.SDK/tree/v0.161.0).

- Schema: [`https://openvibe.network/contracts/agent/timeline-entry.v1.json`](/docs/contracts/agent.timeline-entry.json)

One entry of the agent's timeline (design 2026-11-07 §2): one step of the agent's work, in one mode, for one person. The Dock shows it: the mode's icon and word, the title, where it ran and why, the outcome, the time and the cost. Only a title, an outcome and a link: never a prompt, a diff or a page. A person sees their own entries; another person's entry is a 404. The audience is 'private' (Only me) unless the person shared the entry through the one Share sheet.
