# Fully uninstall `code-review-graph` (the Python/uv MCP tool).
#
# IMPORTANT: Run this ONLY after closing every Claude Code session that has
# this worktree registered as an MCP server. While a session is live it
# re-spawns `uvx code-review-graph serve`, which self-bootstraps: it
# reinstalls the uv package and rewrites .mcp.json / .claude/settings.json
# hooks within ~10s. The configs are already cleaned on disk; this script
# removes the package + binaries + leftover state once nothing is respawning it.
#
# This does NOT touch `codegraph` (the separate @colbymchenry/codegraph bun tool).
