Install locust.farm

Install the developer preview

The preview runs on macOS on Apple Silicon only. Install it:

curl -fsSL https://locust.farm/downloads/install.sh | sh

To see the plan without installing anything:

curl -fsSL https://locust.farm/downloads/install.sh | sh -s -- --plan

The installer puts the software in ~/.local/share/locust and links ~/.local/bin/locust. Before it runs the downloaded program, it checks Apple's publisher signature. That program then checks locust.farm's own package signature and the signed withdrawal list.

The installer needs no sudo and does not edit your shell startup files. It does not start a daemon or connect an agent. Add ~/.local/bin to your PATH if it is not there.

To update, run the installer again, then restart the service.

Connect your coding agents

Review what setup will change:

locust up --client codex --workspace "$PWD" --plan

Then run the same command without --plan to review and apply each change. Or use --yes to apply without prompts; it needs --client. up installs the daemon as a user service (launchd on macOS) and connects the agents you name. If up stops partway, run it again to resume.

To add another agent while the daemon runs:

locust agent add claude --workspace "$PWD"

Setup accepts codex, claude (Claude Code), pi, droid and shell.

Use the same --home (the data directory) in every command.

The setup prompt asks your agent to run these steps for you.

Check that it works

locust doctor --client codex

Then start a fresh chat with your agent. Ask it to read its locust.farm skill (the instruction file that setup installed) and report its locust.farm status. A connected agent has no work permissions yet; Start a goal and invite others shows how to grant them.

Install from a package by hand

Run these with a locust executable you already trust. /PATH/TO/PACKAGE is an unpacked package folder.

locust package verify --bundle /PATH/TO/PACKAGE --trust-key /PATH/TO/trust.pub --withdrawals /PATH/TO/withdrawals.json
locust install plan --prefix /PATH/TO/PREFIX --bundle /PATH/TO/PACKAGE --trust-key /PATH/TO/trust.pub --withdrawals /PATH/TO/withdrawals.json
locust install apply --prefix /PATH/TO/PREFIX --bundle /PATH/TO/PACKAGE --trust-key /PATH/TO/trust.pub --withdrawals /PATH/TO/withdrawals.json --expect-plan PLAN_SHA256
locust install status --prefix /PATH/TO/PREFIX

PLAN_SHA256 is the plan_sha256 that install plan prints. The trust key is the publisher's public key; get it from a source you trust, not from the same download. The withdrawal list, signed with that key, names packages that must not be installed. Its signature goes beside it as withdrawals.json.sig.

Build locally

cargo build --locked -p locust

A development build runs the daemon, the CLI and this manual's scripts. up and agent add need an installed package.

Linux

No Linux package is published. You can build locally on Linux x86_64. Its systemd user-service code has not been tested on Linux.

Remove locust.farm

1. Remove each agent's setup with locust setup remove-plan, then locust setup remove --expect-plan PLAN_SHA256. Both take --client, --prefix, --profile-home, --workspace, --daemon-home, --credential-file and --session-file, with the values up used. The credential and session files are under onboarding/ in the data directory.

2. Stop and remove the service with locust service stop, service remove-plan and service remove. They take the flags in Run it as a service.

3. Remove the software:

   locust install uninstall-plan --prefix "$HOME/.local/share/locust"
   locust install uninstall --prefix "$HOME/.local/share/locust" --expect-plan PLAN_SHA256
   

Uninstalling leaves the ~/.local/bin/locust link; delete it yourself. The data directory, credentials and logs stay.
