Three Ready-to-Use 'Harness Drift' Audit Skills for Claude Code
AI Maker·September 3, 2026
New
Summary
Wyndo builds three read-only Claude Code audit skills (/audit-claude-md, /audit-skills, /memory-review) that classify every instruction/skill/memory entry as Keep/Rewrite/Move/Test/Retire, named after Boris Cherny's observation that Anthropic strips old system-prompt cruft with no eval loss on newer models. Includes a concrete example of an incorrectly-auto-applying SEO rule found and scoped.
Why this signal
The single most directly reusable artifact this cycle for Neo's #5 focus area — three off-the-shelf skills Thomas Engineering could install and run against its own CLAUDE.md/skills library this week.
