Can it fix the errors automatically?

While its primary role is validation, Claude can use the generated report to suggest and apply specific code fixes or configuration changes.

What does this skill actually validate?

It validates file structures, server-side MCP implementation, widget HTML formatting, and tool response schemas to ensure your ChatGPT App works correctly.

Why is the Server class check important?

ChatGPT Apps require the base Server class from the MCP SDK rather than the McpServer class to handle specific session and transport requirements.

Does it support database validation?

Yes, it verifies SQL migrations, the presence of mandatory user_subject columns, and ensures indexes exist for user-specific queries.

セキュリティとテスト

Validates ChatGPT App implementations to ensure compliance with required schemas, MCP protocols, and UI/UX standards.

The ChatGPT App Validator is a specialized diagnostic skill for Claude Code designed to audit and verify ChatGPT App projects before testing or deployment. It performs a comprehensive suite of checks including file structure integrity, server-side implementation patterns, and widget configuration accuracy. By analyzing your codebase for specific MCP SDK classes, structuredContent responses, and skybridge-compatible MIME types, this skill helps developers identify critical configuration errors and architectural deviations that could lead to failed deployments or broken user interfaces.
