Adds the chat.agent({...}) task definition (server runtime) and the
browser-side TriggerChatTransport + AgentChat that drives it from a
React or Next.js app. The runtime sits on top of the Sessions primitive
and handles the durable conversational task lifecycle.
Server runtime:
- chat.agent({...}) — session-aware task definition
- Lifecycle hooks: onChatStart, onTurnStart, onTurnComplete, onAction,
onValidateMessages, hydrateMessages
- chat.history read primitives for HITL flows
- chat.local, chat.headStart, chat.handover, oomMachine
- Delta-only wire + S3 snapshot reconstruction at run boot
- Actions are no longer turns
Browser transport:
- TriggerChatTransport (ai-sdk Transport): delta-only wire sends,
SSE reconnection with lastEventId resume, stop/abort cleanup,
dynamic accessToken refresh
- AgentChat: direct programmatic API
- useTriggerChatTransport (React hook)
- chat-tab-coordinator: cross-tab leader election
Includes the chat-agent, chat-agent-delta-wire-snapshots,
chat-history-read-primitives, chat-head-start, chat-actions-no-turn,
chat-session-attributes, agent-skills, and mock-chat-agent-test-harness
changesets.
Summary
- Implemented metrics dashboards with a built-in dashboard and custom
dashboards
- Added a "Big number” display type
What changed
- New data format for metric layouts and saving/editing layouts
(editing, saving, cancel revert)
- QueryWidget usable on Query page and Metrics dashboards
- Time filtering, auto-reloading and timeBucket() auto-bin support
- Filters added to metrics; widget popover/improved history and blank
states
- Side menu:
- Metrics/Insights section with icons, colors, padding, collapsible
behavior and reordering of custom dashboards
- Move action logic into service for reuse and API querying; refactor
reordering for reuse

What changed
- Upgraded recharts to 2.15.2
- Added multiple chart types and components: big number, line, stacked,
bar (including zoomable & reference line), big dataset bar, and usage
graph
- Implemented custom legend with animated values, tooltip showing x-axis
data, and hover/highlight behaviors for stacks and legend
- Added loading, no-data, and invalid chart states plus loading spinners
and improved loading animations/layout
- Storybook integration: initial charts setup, separate chart files,
alphabetized menu, chart state toggles, and story updates
- Interaction & UX improvements: zooming (drag/select), crosshair
pointer, show/select dates while zooming, prevent text selection on
drag, hide mouse wheel zoom, capped legend items, axis/legend styling
tweaks, better spacing, and min-height for charts
- Data & state handling: moved date data to route for unified zooming,
moved chartState to main Chart component, moved hard-coded/mock data out
of components, and set chart data when zooming to start/end dates
- Performance & animation: turned off/reduced chart animations, sped up
animated numbers, removed hover transitions for bars
- New UI primitives and layout: Card component, small card updates, SVG
icons, improved segmented control and popover variants, table
improvements (resizable columns, filtering, sorting, scrolling fixes)
- Various fixes and polish: tooltip style fixes, legend value updates,
hover/leave state resets, bar width fixes for small datasets,
type/import fixes, and numerous small style/typo tweaks

Summary
- Improve query experience and safety across ClickHouse and TSQL.
Changes
- Display JSON columns when in non-pretty mode (no longer show [Object
Object]).
- Sanitize ClickHouse errors originating from TSQL.
- Remove tenant details from errors.
- Add AI-assisted error-fixing for queries.
- Improve code quality and readability.
- Provide autocomplete support for enum values.
- Enforce limits on ClickHouse queries (10s query limit).
- Add org-level and global concurrency limits.
- Warn and train AI to avoid SELECT *; when used, only return core
columns and show info.
- If AI suggests no time range, default to past 7 days.
- Format the default query for readability.
- Add an admin-only EXPLAIN button.
- Prevent impersonation queries from being saved to history.
TRQL (pronounced Treacle like the delicious British dark sweet syrup) is
the TRiggerQueryLanguage. It allows users to safely write queries on
their data. The queries are safely turned into ClickHouse queries which
are tenant-safe and not SQL injectable.
https://github.com/user-attachments/assets/bbfca473-b3fc-4150-8fe6-79e8840a2d29
This started out as a translation of HogQL by PostHog from Python to
TypeScript.
Features
- Tenant safe queries.
- Many underlying ClickHouse features including functions and
aggregations.
- Virtual columns, which are exposed to users as real columns but are
actually expressions.
- Transformations of data types and where clauses.
- Simple JSON path querying.
- Limits on execution time.
- Reporting of query statistics.
## Query page
There’s a new Query page (currently behind a feature flag) where you can
write TRQL queries and execute them against your environment, project or
organization.
Features
- Executing TRQL queries
- Syntax highlighting and errors
- Autocomplete
- AI generation/editing of queries
- Help and examples
- Table with auto-inferred data types from the table schema
- Table cell renderers for our special types like Run ids, environments,
machines, tasks, queues, etc.
- Copy/export as CSV/JSON
- Line and bar graphs with grouping and stacking
- History of queries
