bus-band

A Claude Code mod (Claude Code 2.1.287+) that draws a band above the prompt with the messages waiting for this session on the Agent Team OS bus.

Bus alita/work-hub: 2 in attesa, 1 urgenti o alta (+1 di altri workspace)  [Nascondi]
!! [ALTA] da kai: crewmoor-stato-piano-v1
   [normale] da vera: content-brief

• UI text is in Italian (the agents' working language). Shows only when something is pending; disappears when the inbox is empty.
• Same scoping as the shell lib (v1.4): agent from AGENT_MAP.json by cwd prefix, slug = workspace basename, shared root inboxes/<agent>/ plus inboxes/<agent>/@<slug>/, messages whose context.project_path belongs to another workspace counted apart.
• Priority is spelled out (URGENTE, ALTA, a !! marker), never colour alone.
• A toast when a new urgent/high message arrives. Polls every 20 s and at the end of every turn.
• /bus-band toggles it; the Nascondi button hides it until the next new message.
• Read-only: it never moves, archives or writes a message. /read, /inbox and the MCP tools stay the way to act on them.
• Honours AB_HOME like the shell lib (default ~/.agent-team-os).

Install

The mod is its own plugin, separate from the main agent-team-os plugin, so a manual install (hooks registered in settings.json) never gets its hooks registered twice.

With install.sh (manual install): the installer copies it to ~/.claude/mods/bus-band/. Load it in every session by adding the folder to CLAUDE_CODE_PLUGIN_DIRS in the env block of ~/.claude/settings.json:

{ "env": { "CLAUDE_CODE_PLUGIN_DIRS": "~/.claude/mods/bus-band" } }

One session only: claude --plugin-dir /path/to/agent-team-os/mods/bus-band.

Security

Mods are not sandboxed: they run with Claude Code's own access. This one reads ~/.agent-team-os/ and $HOME/AB_HOME, nothing else, and makes no network call. Check with claude plugin validate mods/bus-band, which lists every engine call and env variable the module touches.

Develop

claude plugin validate mods/bus-band   # manifest, hooks, calls, state contract
claude plugin test mods/bus-band       # hooks/bus.test.ts: cwd→agent, slug, scoping, sort

The pure bus logic lives in hooks/bus.ts (mirrors scripts/agent-team-os-lib.sh); hooks/register.tsx holds the hooks and the drawing. Known gap: the shell lib also matches the realpath of the cwd; the mod matches the cwd Claude Code reports, which is already resolved in practice.
