I was playing around with LLMs, but I kept running out of tokens. A lot of them went to reading files, often ones that had nothing to do with my prompt.

When you're looking for something, you don't read everything. You skim the headings or the first line of a paragraph, and read closely only when you find something relevant. I wanted an agent to do the same.

I wrote two Claude Code skills for it. The first, checkpoint, writes a short description of every file in a folder. The second, skim, has the agent read those descriptions first and only open the files that matter.

I'm still working on ways to improve my workflow.
