SkillCI catches when a Claude model update silently breaks your Skill trigger stops firing, an instruction gets ignored, a redteam attack succeeds. Instead of just failing CI, it writes the failure as a permanent eval case you review and accept: catch once, covered forever. Also: OWASP-mapped local security lint, git-native bisect to find the breaking commit, and cross-model regression testing. Free, open source, single Go binary.
