+# skill-md-validator
+
+Validate your skill.md files before publishing.
+
+## Install
+
+```bash
+npm install -g skill-md-validator
+```
+
+## Usage
+
+```bash
+# Local file
+skill-validate ./skill.md
+
+# Remote URL
+skill-validate https://example.com/skill.md
+
+# Strict mode (warnings become errors)
+skill-validate --strict ./skill.md
+
+# JSON output
+skill-validate --json ./skill.md
+```
+
+## Why
+
+skill.md files are how agents discover and understand capabilities. A malformed file means agents can't find you or misunderstand what you offer. Validate before you ship.
