AI Skill: Validate Your GSDK Integration

This repo includes a validate-gsdk Agent Skill that checks your GSDK integration for common mistakes — missing callbacks, threading issues, deprecated APIs, and more. It works with GitHub Copilot and Claude Code.

To use it, copy the skill into your game server project:

# GitHub Copilot
cp -r path/to/gsdk/.github/skills/validate-gsdk .github/skills/

# Claude Code
cp -r path/to/gsdk/.github/skills/validate-gsdk .claude/skills/

Then ask your AI assistant:

Use the /validate-gsdk skill to check my GSDK integration.

See the skill README for full details and example output.
