# Build a wheel + sdist, install the wheel into a scratch venv with the [mcp]
# extra, and run packaging smoke checks. Use this before tagging a release.
#
# Usage: scripts/verify_wheel.sh
#
# Requires: python3.10+, pip. Will create a scratch venv under /tmp and
# remove it on exit.
#
# This script does NOT publish to PyPI. It does NOT run network-dependent
# MCP server checks beyond `agentveil-mcp --help` (argparse-only).
