AgentCollision AgentCollision Docs

Quickstart

Sign up, install the daemon, and see AgentCollision blocking conflicts between two Claude Code sessions — in about two minutes.

1. Sign up

Create an account at dashboard.agentcollision.com. The Free tier works forever; Team and Enterprise include a 14-day trial with no credit card required.

The dashboard is where you see what every chat is doing across your team — leases, decisions, cross-chat messages, spend.

2. Install the daemon

One command, works on macOS, Linux, and WSL:

curl -fsSL https://install.agentcollision.com | sh

The installer detects Homebrew and uses it automatically if you have it (you get auto-updates and clean uninstall for free). Otherwise it downloads the binary directly. Either way, the agc command lands on your PATH and the daemon registers to start at login.

Verify:

agc --version
agc status
Windows users: use WSL (Windows Subsystem for Linux). A native Windows installer is on the roadmap. Once in WSL, either install method above works.

3. Connect this machine to your account

Run:

agc login

This opens your browser to dashboard.agentcollision.com/device. You'll see a short code like ABCD-1234; confirm it matches what your terminal shows, then click Approve. Your terminal finishes logging in automatically.

What happens after login.
  • As of v0.11.6, AgentCollision auto-protects every git repo on your machine. There's no agc init step per repo — if it's a git repo, it's covered.
  • As of v0.14.0, agc login is additive. Running it again with a different account doesn't sign out the first one — both stay registered. Flip between them with agc team switch <name> or the dashboard's one-click Switch this laptop to this team button. See Multi-account on one machine.
One signup, whether you're alone or on a team. Every install connects to an account so you get the dashboard, audit log, and policy enforcement out of the box. The Free tier is free forever; you move to Team or Enterprise when you add a second machine or invite teammates.
Watch it come online. Leave the dashboard open. As soon as the daemon sends its first heartbeat, your machine card flips to a green Active state. That's the end-to-end round trip.
macOS users — first-run warning: the AgentCollision binary isn't yet code-signed. If you installed via curl, the installer clears the quarantine flag for you. If you installed via brew, Homebrew handles it. If you still see a “cannot be opened because the developer cannot be verified” warning, run:
sudo xattr -d com.apple.quarantine $(which agc)
sudo spctl --add $(which agc)

4. Enable the hook in your AI tool

The daemon coordinates by intercepting every AI tool's PreToolUse hook. The install script wires hooks up automatically for every supported tool it finds:

If you installed a tool after running the installer, re-run it — the script is idempotent and will detect the new tool.

5. See it working

Open two Claude Code sessions in the same repo. In each one, ask Claude to edit the same file. The second session will be blocked synchronously:

Edit denied: file auth.ts is held by claude-code/abc12345 (expires in 28m)

Open the dashboard — Overview shows every active lease and chat in real time, across every machine on your account.

6. (Optional) Invite your team

To coordinate across multiple developers, invite them from the Team page in the dashboard. They each get an email with a one-click accept link, pick their own password, and get the same personalized install command on their machine. Details: Invite your team.

Privacy. File paths are HMAC-hashed before leaving your machine. The hosted coordinator never sees your actual code or directory layout. See Privacy model.
