#!/bin/sh
# kbagent bootstrap installer.
#
# Usage:
#   curl -LsSf https://raw.githubusercontent.com/keboola/cli/main/install.sh | sh
#
# Installs the kbagent CLI from a PREBUILT wheel attached to the latest GitHub
# release -- no source build. This is the fast path for issue #353: building
# from `git+` recompiles the bundled React SPA via npm on every install, which
# takes 2-4 minutes on WSL2. A prebuilt wheel is a few-seconds download instead.
#
# Requirements: `uv` (the install backend) and `curl`. The guide installs uv a
# couple of steps before this. If no wheel asset exists for the latest release
# yet (older releases predate the release workflow), this falls back to the
# `git+` source build so the install still succeeds.
#
# Env knobs:
#   KBAGENT_NO_SERVER=1   install CLI-only (skip the [server] extras: FastAPI/
#                         uvicorn for `kbagent serve`). Default bundles them so
#                         `kbagent serve --ui` works out of the box.
