Why I scrub AI prose with regex, not a second LLM

TL;DR

klaussy-agents is a free, MIT-licensed CLI (pip install klaussy-agents) that makes the prose an AI coding agent writes, PR comments, review notes, commit messages, read like a person wrote them. It works in two layers: a humanization spec baked into the agent's skills so it writes clean prose up front, and a deterministic klaussy humanize pass that scrubs the output afterward. The scrubber is rule-based regex, not an LLM, and it never touches code. There's also a part I didn't expect going in: once the AI tells are gone, what's left can read curt and run long, so the spec also handles tone (don't be rude) and length (one sentence for a reply, one to five for a review comment).
