Writing
All essays →I Recommended Skills. Then I Measured Them.
Two posts ago I told you to move CLAUDE.md into skills, because skills only load when you need them. Then I measured mine across 84 headless agent runs: 7,778 tokens of index before I type a word, a retrieval turn that costs more than the file it replaced, and 28 out of 28 unprompted invocations that refuse to reproduce the eval everyone is quoting.

Work with me
I take on a few freelance projects a year — the kind where the frontend is the hard part.
