+---
+
+# Plugin Metadata Skill
+
+Expert metadata management for Claude Code plugins with validation, versioning, and marketplace entry generation.
+
+## Operations
+
+- **validate** - Validate plugin.json completeness and correctness
+- **update-version** - Update version with semantic versioning validation
+- **add-keywords** - Add or update keywords for plugin discoverability
+- **marketplace-entry** - Generate marketplace.json plugin entry
+
+## Usage Examples
+
+```bash
+# Validate metadata
+/plugin-metadata validate plugin:my-plugin
+
+# Update version
+/plugin-metadata update-version plugin:my-plugin version:1.1.0
+
+# Add keywords
+/plugin-metadata add-keywords plugin:my-plugin keywords:"testing,automation,python"
+
+# Generate marketplace entry
+/plugin-metadata marketplace-entry plugin:my-plugin source:"github:username/plugin-name"
+```
+
+## Router Logic
+
+Parse operation from $ARGUMENTS and route to appropriate instruction file:
+- "validate" → `{plugin-path}/commands/plugin-metadata/validate-metadata.md`
+- "update-version" → `{plugin-path}/commands/plugin-metadata/update-version.md`
+- "add-keywords" → `{plugin-path}/commands/plugin-metadata/add-keywords.md`
+- "marketplace-entry" → `{plugin-path}/commands/plugin-metadata/create-marketplace-entry.md`
