You can read all of the prompts in Plandex (open source CLI coding agent focusing on larger projects): https://github.com/plandex-ai/plandex/tree/main/app/server/m...

They're pretty long and extensive, and honestly could use some cleaning up and refactoring at this point, but they are being used heavily in production and work quite well, which took a fairly extreme amount of trial-and-error to achieve.
