You're debugging something with ChatGPT, Claude, or Cursor, and you hit the wall every developer knows: the model needs to see your code. So you start the dance — open a file, copy, paste, type "and here's the other file", paste again, label it so the model doesn't get confused… five files later you paste the whole thing and get back "this conversation is too long." Now you're trimming blind, with no idea how many tokens you actually sent.
I got tired of doing this by hand, so I built ctxstash: one command that walks a directory and emits a single, tidy Markdown document with every file fenced and language-tagged, a file-tree overview at the top, and an approximate token count so you know up front whether it'll fit.
