If you're copying code from a chat window into your editor, you're using 2024 patterns. Let the agent write directly to files.
Instead: Use Claude Code / Copilot CLI in your repo directory.
If a CLI already exists (git, az, dotnet), don't build an MCP server that wraps it. You're adding overhead for zero capability.
Instead: Write a skill file that teaches the agent how to use the existing tool.
"Make this code better" gives you random refactoring. "Fix the null reference on line 42 of Initialize.cpp" gives you a fix in 30 seconds.
Instead: Be specific about what you want. Context in, quality out.
Merging agent code without reading it is dangerous. But refusing to let the agent touch files is pointless. Both extremes waste your time.
Instead: Treat it like a capable junior. Review the output, not every keystroke.
