Properties sidebar
The properties sidebar sits to the right of the artifact content. It shows the artifact's current state, who owns it, how approval is progressing, and how the artifact connects to the rest of the project.
Review readiness
The Review readiness card appears when the artifact is in review, or when there are outstanding findings or markers from a previous review. It shows a status line (blocked, at risk, or ready) and a count of each item type blocking or flagging approval:
A zero count renders in a muted tone; absence is not a signal.
Properties
The Properties section lists the artifact's core metadata.
Changing the assignee
Click the Assignee row to open a member search popover. Select a member to assign them, or press Unassign to clear the field.
Version history
Click the version number to open a popover listing all versions of the artifact. Each row shows the version number, who made it, and when. For any version other than the current one, a restore icon lets you copy that version's content into a new draft. See Versions and history for how restore works.
Agent cost
The Agent Cost row shows the estimated total LLM spend across all generation runs for this artifact. Click the figure to open the Activity sheet at the Traces tab, where you can see a breakdown per generation run.
Approval progress
When the artifact is in review, an Approval progress card appears below the properties list. It shows how many approval levels the artifact needs and which are complete.
Dependencies
The Dependencies section shows the artifact's position in the project's delivery DAG. Each entry is a dependency the artifact depends on, with its status. All dependencies must be approved or locked before this artifact can be submitted for review.
Implementation
The Implementation section appears when the artifact has an associated implementation. It includes:
Not all fields appear for every artifact. A spec artifact in early implementation may show only a branch; a completed one may show a pull request and a preview URL.
Upstream Change warning
When a source the artifact was built from has changed since the last generation, the sidebar shows an Upstream Change warning. Choose Regenerate from the overflow menu to produce a new draft from the updated sources.
Pending action
Canvas artifact types (design, deck, wireframe) may show a Pending action section at the bottom of the sidebar when the artifact has open review questions. These are UIR-n requirement proposals that need to be sent to the PRD or dropped before the artifact can be approved. See Design canvas for how requirements flow to the PRD.
