It is genuinely useful on its own. I have enjoyed discovering the things I want and adding them bit by bit. I'm doing quite well with just a "todos" extension, and a "plan" prompt template (doesn't enforce read only tool usage, but prompts to build todos and discuss before doing anything). I will probably try out some subagent systems soon, but I'm doing surprisingly well without them.
