design: vibe_* live worker TV-wall surface

[joeshull]

Child of #135

Needs a design session. vibe_* is one live multi-worker surface, not five cards.

Problem

TUI vibe renderer is a persistent worker “TV wall” (vibe.ts spawn/send/wait/kill/list). vibe_wait streams 500ms interim screen snapshots. A completed-result Generic card is not the product.

Dashboard has no worker-session store analogous to subagents.

Design questions

1. One session-level vibe panel vs per-tool-call cards that project into a shared wall?
2. Does tool_execution_update.details already carry enough screen snapshots, or is a new event channel required?
3. How do spawn/send/wait/kill/list share identity (worker id) across tool rows?
4. Parity target: TUI TV wall, or a thinner list + last-screen?

Tools in this issue

vibe_spawn, vibe_send, vibe_wait, vibe_kill, vibe_list — one session, do not split.

Pointers

• @oh-my-pi/pi-coding-agent/src/tools/vibe.ts (~77–93, 161–191, 482–593)
• Dashboard analog: AgentToolRenderer + subagent map in event-reducer.ts

Proposal (unreviewed)

Draft from design session. Not locked.

Rec

A. One VibeToolRenderer for all five vibe_* names. Ordinary chronological cards. Worker-id header + last-screen list from details.screens. No session pane / TV wall.

Approaches

• A (rec): per-call cards; vibe_wait updates in place from existing 500ms tool_execution_update
• B: session-level worker store/panel
• C: Generic result cards only

Locked answers (proposed)

1. Per-call cards, not a session-level wall
2. Existing tool_execution_update is enough. No new WS
3. Identity from VibeToolDetails (spawned.id / send.id / killed.id / screens[].id)
4. Parity = thinner list + last screen, not TUI TV wall

UX

display-only. No controls.

Out

No vibe map/panel, no composer animation, no #120 unwrap, no input protocol.
