Tells Claude when the skills it follows are wrong
Skill Health checks the instructions in the Claude Code skills you use against the current docs of the software they're about. At the start of every session, it tells Claude what's true instead, with a source link. It edits a skill only if you approve. A Claude Code plugin plus a macOS menu bar app (macOS 27). Free and open source (Apache 2.0). Early: tested on one person's skills so far.
Skill Health is a free and open-source tool that verifies the accuracy of Claude Code skills against current software documentation, providing corrections with source links. It functions as a macOS menu bar app and requires user approval before editing any skills.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
