0.17.0 is about reading a session, not just storing it. A new timeline service derives highlights, segments, and events for any session directly from the ingested graph, so studio can show what happened in a run without asking an LLM to summarize it.
The studio share view gets a design pass to match: a session-outcome header, unified rendering for tool calls in transcripts, and URL-driven subagent selection so deep links land on the right view.
Highlights
- Session timelines (highlights, segments, events) are computed from the graph - no LLM in the loop.
- Shared sessions open with an outcome header from the studio design pass.
- Tool calls render through one unified transcript treatment in studio.
- Subagent selection in the share viewer is driven by the URL.
- Session inspect paging, session-detail skills, and the workflow dashboard are all faster.
Why it matters
A telemetry graph is only useful if you can read a run back quickly. Deriving the timeline from evidence instead of a model keeps it instant, deterministic, and free - and it makes shared sessions legible to people who weren't there.
