Audit and slim down bloated CLAUDE.md files — and other overlong project markdown like READMEs — by applying progressive disclosure. Use whenever the user asks to audit, trim, shrink, slim, refactor, declutter, restructure, or optimise a CLAUDE.md (or AGENTS.md / project memory) file, says their CLAUDE.md or README is too long or bloated, mentions context bloat or token waste from project instructions, wants rules moved into .claude/rules/ or subdirectory CLAUDE.md files, wants long docs split into linked pages, or asks about @imports or progressive disclosure — even if they don't name the file explicitly (e.g. "my project instructions are getting out of hand").

The fix is not to delete knowledge but to move each piece to the place where it loads only when actually needed. This skill audits a CLAUDE.md, classifies every section, then restructures the file with the user's approval.
