The Session Pane

The session pane occupies the rightmost 35% of the terminal, spanning the full height from below the worktree tab row down to the status bar. It displays the agent conversation – prompts, responses, tool calls, and tool results – for the currently active session.

Border Titles

The session pane border carries information in three positions:

Session names: Custom names are preferred for readability. When no custom name has been set, UUIDs are shown in truncated form as [xxxxxxxx-...] to save horizontal space.

PID badge: While an agent process is running, the process ID is shown in green (PID:12345). When the process exits, the badge switches to an exit code: green for exit code 0, red for any non-zero exit code.

Border Styling

The border appearance changes based on context:

• Focused: AZURE (#3399FF) with double-line border and bold.
• Unfocused: White with plain single-line border.
• RCR active: Green with bold border, indicating active conflict resolution. A bottom-border hint shows Ctrl+a Accept/Abort.

The bottom border also displays the current model name, color-coded by model family:

Conversation Layout

Messages render in an iMessage-style bubble layout:

• User messages are right-aligned with an AZURE accent bar and You < header. Text wraps within the bubble width.
• Assistant messages are left-aligned with a header showing the backend name (Claude > in orange, Codex > in cyan) and model identifier. The header fills the full bubble width with the model name right-aligned.
• Tool calls appear as timeline nodes beneath assistant messages (see Tool Call Display).

An empty session pane (no session loaded) shows a hint: “Press s to choose a session or a to create one.”

Filtered Messages

Several message types are hidden from the conversation display to reduce noise:

• Meta messages (isMeta: true) – internal Claude instructions that the user never needs to see.
• Internal markers – <local-command-caveat>, <task-notification>, and <local-command-stdout> tags are stripped before rendering.
• Rewound/edited user messages – when a user edits a previous message, only the corrected version is shown. Deduplication uses the parentUuid field to identify and suppress superseded messages.
• TodoWrite tool calls – suppressed from the inline stream because they are rendered separately in the sticky Todo Widget.

Slash Commands

User messages containing <command-name>/xxx</command-name> tags are rendered as centered 3-line magenta banners instead of normal user bubbles. The command name is displayed prominently, making it easy to spot slash command invocations when scrolling through a session.

Compaction Banners

Two banners indicate context compaction status:

• “Context compacted” – green banner, centered, shown after compaction finishes successfully (both the Compacting and Compacted events produce this).
• “Session may be compacting…” – yellow warning banner, injected by the inactivity heuristic when context usage is at or above 90% and no events have arrived for 20 seconds.

Hook Display

Hooks (permission checks, tool validations) are captured from multiple sources in the event stream (hook_progress, system-reminder tags, hook_response). They render as dim gray lines near their corresponding tool calls, prefixed with ›. Consecutive duplicate hooks are deduplicated to prevent visual clutter.

Scrolling and Navigation

• j / k scroll one line at a time.
• Up / Down arrows jump to the previous / next message bubble.
• J / K page scroll (viewport height minus 2 lines of overlap).
• Alt+Up / Alt+Down jump to the top / bottom of the session.
• Mouse wheel scrolling works regardless of keyboard focus.
• The session pane auto-follows new content (pinned to bottom) until the user scrolls up. Scrolling up detaches from the bottom; scrolling back to the end re-attaches.

Session Find

Press / to open an in-session search bar at the bottom of the session pane. Type a query to highlight matches in the conversation. n and N navigate between matches. The search bar shows a current/total match counter. Press Esc to dismiss the search bar; matches remain highlighted until the query is cleared.
