BB Thread Hover Cards

This standalone repository is retained for history. Active development moved to brsbl/bb-plugins.

Thread Hover Cards is a plugin for bb, the agentic IDE for running and managing coding agents across projects, threads, and environments. It turns the sidebar into a fast status overview: hover or keyboard-focus a thread to see what the agent last said and the context it is working in.

bb plugins are full-trust TypeScript packages that can add app UI, server capabilities, commands, and background services to a running bb instance. This plugin uses bb's existing Plugin SDK and thread-row semantics; it does not require new bb APIs.

What it shows

• Provider, model, reasoning level, and access mode.
• Current thread status and turn runtime.
• The latest completed agent message, with Markdown-aware truncation.
• Project, branch, and linked pull-request state, or a compact local workspace path.

Install

Enable Plugins under Settings → Experiments, then install the public, git-backed plugin:

bb plugin install git:https://github.com/brsbl/bb-plugins.git@plugin/thread-hover-cards --yes

For local development, install the checkout instead:

bb plugin install .

Development

npm ci
npm run check
bb plugin reload thread-hover-cards

Compatibility

BB Plugin SDK 0.4 has no thread-row hover slot. The frontend therefore anchors to BB's stable data-sidebar-thread-id attribute; typed RPC supplies all thread, repository, and PR data. A future native slot should replace only this small DOM bridge.
