Overview

Ctx Doctor is a security-tested development skill for Claude AI that runs diagnostics on the context-mode setup. It checks various components such as runtimes, hooks, FTS5, plugin registration, npm, and marketplace versions. The tool can be invoked directly and provides a plain-text status report.
