A bloated CLAUDE.md can make your coding agent worse. Anthropic's fix is one command: /claude-api prompt-audit, which audits your CLAUDE.md, skills, subagents and harness, then rewrites the waste — applying nothing until you approve. Reported results: 9% lower cost and 2 points higher accuracy with the same model, purely from better instructions. The post also links the author's article on a practical 5-layer setup for shared memory across Claude Code, Codex, Cursor and OpenCode.
