Claude Code renames prompt-audit command to /checkup, scans CLAUDE.md for stale instructions

petergyang · x · 2026-09-26

Lydia Hallie renamed the Claude Code command /claude-api prompt-audit to /checkup prompt-audit, since the old name implied it was API-only even though it always worked on the whole Claude Code setup. The command audits your CLAUDE.md, skills and agents for instructions the model no longer needs. Peter Yang suggests auto-triggering it whenever someone edits skills or prompts.
