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.

Supported agents

Agent	State detection	Review & forking
Claude Code	Hooks + classifier	Yes
Codex	PTY heuristics + transcript classifier	No
Copilot CLI	PTY heuristics + transcript classifier	No

Install

Homebrew cask (desktop app)

brew tap victorarias/attn https://github.com/victorarias/attn
brew install --cask --no-quarantine victorarias/attn/attn

This installs attn.app (with bundled daemon/runtime binary). It does not add attn to your shell PATH.

Homebrew formula (CLI + daemon only)

brew install victorarias/attn/attn

Install this if you want the attn command in terminal.

Direct DMG

Grab the latest release, open the DMG, drag to Applications.

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 needs attention: asked a question, or finished a long run (5+ min) and is waiting for your review
🟡 Flashing	Agent wants tool approval — go approve
⚫ Gray	Agent is done — move on

Long-run review behavior: if a run takes 5+ minutes, attn keeps it yellow when it finishes, then runs smart done/waiting classification only after you actually view that session (5 seconds stable selection; immediate if you were already focused on it).

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. For 5+ minute runs, classification is intentionally deferred until you visualize the session, so "done" runs still surface for manual review first.
6. gh polls PRs across all your authenticated GitHub hosts.

Build from source

Requires Go 1.25+, Rust (stable), Node.js 20+, pnpm, and Tauri prerequisites.

Source builds intentionally disable GitHub release update banners by default.

git clone https://github.com/victorarias/attn.git && cd attn
