Especially now that Copilot supports MCP I can plug in my own custom "Tools" (i.e. Function calling done by the AI Agent), and I have everything I need. Never even bothered trying Cursor or Windsurf, which i'm sure are great too, but _mainly_ since they're just forks of VSCode, as the IDE.
I'm looking forward to seeing how Agent Mode is better. Copilot has been such a great experience so far I haven't tried to keep up with every little new feature they add, and I've fallen behind.
My favorite tool that I've written is one that simply lets me specify named blocks by name, in a prompt, and AI figures out how to use the tool to read each block. A named block is defined like:
# block_begin MyBlock ...lines of code # block_end
So I can just embed those blocks around the code rather change pasting into prompts.
