Tabs
Sessions
The transcript viewer displays the full conversation between the human and the AI agent:- Message bubbles — Each message shows the role (human or assistant), content, and timestamp
- Token counts — Per-message token usage when available
- Tool calls — Tool names shown as pills/badges on assistant messages
- Avatars — User image and agent icon displayed alongside messages
Plan
If the agent generated a plan during the session, it’s rendered as formatted markdown. This tab only appears when plan data exists (plan_slug is set on the checkpoint).
The plan typically contains the agent’s high-level strategy, step-by-step breakdown, and reasoning for the approach taken.
Files
A unified diff viewer showing all file changes in this checkpoint:- File-by-file breakdown with added/removed/modified indicators
- Syntax-highlighted diffs with line numbers
