Install subagent-cli

There's nothing to install in the traditional sense — subagent.js is the whole program. Download it and run it with Node.

curl -fsSL https://subagentcli.com/subagent.js -o subagent.js && chmod +x subagent.js

That's it. No package.json, no node_modules, no lockfile. The script has zero external dependencies — it uses only Node's built-in global fetch, process, and URLSearchParams.

Requirements

Node.js 18 or later. Node 18 is the first version to ship fetch as a stable global without a flag, and that's the only runtime API this script calls out to the network with. Check your version with:

node --version

If you're on an older Node, upgrade first — there is no fallback HTTP client bundled in, by design (that's what "zero-dependency" means here).

Run it

node subagent.js contracts
node subagent.js tasks tsk_wire_live_cache_graphql
node subagent.js identities --query=surface:macos__desktop_cowork__engineering_coworker

See the full command reference for every resource this script knows about, and every flag it accepts.
