AI Clean Copy — AI skill for Claude Code

---

Select text in an agent TUI, hit `⌘C`, and your clipboard fills with rendering junk: 2-space margins on every line, `⏺` `❯` `⎿` (Claude Code) or `•` `›` (Codex) markers, `✻ Worked for 11s` spinner lines, and hard line breaks at the terminal width that shred your paragraphs.

**ai-clean-copy** is a tiny [Hammerspoon](https://www.hammerspoon.org/) interceptor that catches `⌘C` in your terminal, scores how agent-TUI-like the copied text is, and cleans it *before you paste* — conservatively, so code, tables, and everything non-agent pass through untouched.
