Skillscore: Automated Quality Scoring for AI Agent Skills

AI agent skills are now industry standard, but vague skill definitions waste context tokens and cause unintended triggering—yet most developers ship them without validation. Skillscore is the first automated linter for SKILL.md files, providing objective 0–100 scoring against official authoring guides from Claude, Codex, and Antigravity. With CI-friendly output, deterministic results, and multi-platform support, it brings engineering rigor to skill development.
