Run a Claude (soon also Codex) coding agent on your open project. The agent edits your real files
locally; every model call is metered through the kill9dev gateway on your credits — provider keys
never touch your machine.
Setup (once)
Install the CLI: run kill9dev: Install CLI from the Command Palette (or npm i -g @kill9dev/cli).
kill9dev: Create account (or Log in) — stores your API key.
Use
kill9dev: Run agent — type a task; it runs in an integrated terminal on your workspace.
Reads run automatically; file writes and shell commands ask [y/N] in the terminal, and are
confined to the project folder.
Also on the $(rocket) kill9dev status-bar button.
Settings
kill9dev.gatewayUrl — API endpoint (default https://api.kill9dev.com).
kill9dev.harness — claude (default) or codex.
kill9dev.model — model id (haiku, sonnet, opus, gpt-luna, …). Blank = harness default.
Requirements
Node.js + npm on your machine (used to install and run the CLI).
