Impact Analysis with GitNexus

IMPORTANT — How to use GitNexus: GitNexus is a standalone CLI tool. Run it directly via gitnexus <command> in the Bash tool. Do NOT use mcpl call gitnexus ... or npx gitnexus ... — gitnexus is installed globally and invoked by name.

Multi-repo note: Always pass --repo <name> to every command that operates on a specific repo to avoid "multiple repositories" errors.

When to Use

• "Is it safe to change this function?"
• "What will break if I modify X?"
• "Show me the blast radius"
• "Who uses this code?"
• Before making non-trivial code changes
• Before committing — to understand what your changes affect
