#!/usr/bin/env bash
#
# amplifier-opencode one-line installer.
#
#   curl -fsSL https://raw.githubusercontent.com/microsoft/amplifier-app-opencode/main/install.sh | bash
#
# Review-first (recommended):
#
#   curl -fsSL https://raw.githubusercontent.com/microsoft/amplifier-app-opencode/main/install.sh -o install.sh
#   less install.sh
#   bash install.sh
#
# What this does, and deliberately no more:
#   1. Ensures `uv` is available (installs it via the official astral script if missing).
#   2. Installs the `amplifier-opencode` CLI as a uv tool from GitHub.
#   3. Prints the next command to run.
#
# It intentionally does NOT install amplifier-agent or opencode, and does NOT
# run any credential wizard. That lifecycle lives INSIDE the CLI: the first
# `amplifier-opencode` launch (or `amplifier-opencode setup`) self-heals the
# rest of the stack and walks you through provider credentials. Keeping the
# bootstrap in the tool -- not this script -- is intentional: stdin here is the
# curl pipe, not you, so an interactive wizard cannot run correctly from here.
