# `forklaunch init agent` in a TypeScript app: the agent is a service tagged
# variant = "agent" with the agent routes, tools and agent.config.ts, and the
# command refuses bad input. The Rust agent is covered by
# rust_generated_projects.sh.
#
# Installing and building needs a @forklaunch/core that exports ./agent. Until
# one is published, set FORKLAUNCH_AGENT_CORE_TARBALL to a `pnpm pack` of
# framework/core to build and test the app as well.
