attn

attention hub — because your head shouldn't feel like concrete by 3pm.

I built this after noticing a pattern: I'd start the day sharp, spin up 4-5 AI agents across different repos, and by mid-afternoon my brain was soup. Not from the coding — from the managing. Which terminal has the agent that's stuck? Did that one finish? Wait, who asked me a question 20 minutes ago? Alt-tab, alt-tab, alt-tab, scroll, squint, repeat.

attn fixes the dumbest part of multi-agent workflows: knowing what needs you right now.

It's a desktop app that wraps your agent CLIs — Claude Code, Codex, Copilot — and puts them all in one window with color-coded status. Green means working. Yellow means "hey, I need you." Gray means done. No more tab-hunting. No more heavy head.

There is no custom agent UI. attn wraps each CLI directly. You get the real, native experience of every agent — just organized.

What you get

One sidebar to rule them all — Every agent session, live state at a glance. The one that needs you glows. Click it. Done.

Embedded terminals — No more "which terminal was that in?" Run agents inside the app. Open utility shells next to them. Resume sessions, fork them, never leave the window.

Code review — Full diff viewer with inline comments and AI-assisted review. Claude reads your branch, leaves comments, you resolve them. All without opening a browser. (Claude only)

PR dashboard — Your PRs, your review requests, CI failures, merge conflicts — one place. Works across GitHub.com and GitHub Enterprise. Open a PR directly into a worktree.

Git worktrees & branches — Parallel agents need parallel branches. Create, switch, and manage worktrees from the app. Stop stepping on your own feet.

Quick Find — Cmd+F to yank URLs, paths, and hashes out of terminal output.

Updating

# Formula
brew update && brew upgrade victorarias/attn/attn

# Cask
brew update && brew upgrade --cask victorarias/attn/attn

The app nudges you when a new release exists. No auto-install — you pick when.

Prerequisites

• macOS (Apple Silicon)
• At least one agent CLI installed
• GitHub CLI (gh) v2.81.0+ for PR features

Quick start

1. Launch attn from Applications (or just type attn).
2. Cmd+N — pick an agent, pick a directory, go.
3. Watch the sidebar. Colors tell you who needs you.

Session states

Color	What it means
🟢 Green	Agent is working — leave it alone
🟡 Yellow	Agent has a question — go help
🟡 Flashing	Agent wants tool approval — go approve
⚫ Gray	Agent is done — move on

Shortcuts

Shortcut	What it does
Cmd+N	New session
Cmd+Shift+N	New session in a worktree
Cmd+Shift+F	Fork session (Claude)
Cmd+F	Quick Find
Cmd+K	Attention drawer (who needs me?)
Cmd+`	Utility terminal
Cmd+Up / Down	Jump between sessions
Cmd+R	Refresh PRs

CLI

attn                 # Open app, start session
attn -s myproject    # Session with a label
attn --resume        # Resume via agent's native picker
attn list            # All sessions as JSON
attn daemon          # Run daemon in foreground

How it works

1. attn wraps your agent CLI and installs hooks (Claude) or reads PTY output (Codex, Copilot) to detect state.
2. A background daemon tracks sessions via unix socket (~/.attn/attn.sock).
3. The desktop app connects over WebSocket for real-time updates.
4. A lightweight classifier figures out if Claude stopped because it's done or because it's waiting for you.
5. gh polls PRs across all your authenticated GitHub hosts.
