AI-Generated Review

What is skill-lint?

Skill-lint is a browser-based skill linter for validating SKILL.md files—structured Markdown docs that define AI behaviors for tools like Claude. Paste your file into the zero-install JavaScript app, and it delivers live linting across 20 rules, a quality score from A-F, token estimation for context limits, and SKILL.md-aware syntax highlighting. It solves sloppy skills getting ignored by spotting errors like missing frontmatter or vague triggers before deployment.

Why is it gaining traction?

No npm, no server, no data leaks—just open in any browser for instant feedback with line-jump fixes and drag-drop support. Token estimation benchmarks against 8k-200k contexts, while the score tracks improvements objectively. In a sea of browser-based GitHub tools like IDEs or text-based browsers, its zero dependencies and AI-specific linting make it a quick win for skill lintzaag without setup friction.

Who should use this?

AI prompt engineers iterating on Claude skills, developers building browser-based games or tools with SKILL.md integrations, and teams maintaining cross-tool AI workflows. It's ideal for frontend devs using Chrome, Chromium, or Firefox-based browsers who need fast validation during prototyping, without bloating their stack.

Verdict

Grab it for niche SKILL.md work—solid docs, unit tests, and Netlify deploys show care, despite 12 stars and 1.0% credibility signaling early maturity. Fork the MIT code if you need custom rules; it's a lightweight linting essential for AI skill authors.
