I'm about to leave my job, and I have to hand in my notice next week. I need to prepare some documentation for my replacement, but honestly, the codebase is a tangled mess with years of patches. I really don't want to spend my last week crafting a lengthy Wiki that probably won't get read. Is there a tool that I can use that scans my private GitHub repo and generates a 'Survival Guide'? I'm looking for something that highlights where API keys are stored, which files are risky, and how to start the server correctly.

Why haven't you been documenting all along? You might want to let your new boss know if this has been an issue for you.
Cursor's 'plan mode' might be exactly what you need for this situation!
There are definitely tools that can help! Look into Cursor, Antigravity, or Claude Code. Honestly, if your successor uses one of those, they might manage just fine without your documentation. Focus on documenting areas that involve complex dependencies, DevOps configurations, or anything that won't be immediately obvious from the code.
You should have been keeping your documentation up to date as part of good coding practices. It's always better to clean the code and write documentation as you go along. Think of your next colleague as someone who could easily make serious mistakes without the right context. Sounds tough but these practices really help in the long run!
You might consider offering the company a fee for support after you leave. That way, you can cover your bases without spending all your time documenting everything now.
