What happens if my skill has more than 20 files?

The converter provides a consolidation workflow to merge related references and prioritize core documentation to fit within OpenAI's 20-file knowledge limit.

Can it convert Claude scripts to GPT Actions?

Yes, it identifies API calls within your scripts and provides a workflow to transform them into OpenAPI specifications for use with GPT Actions.

Does it support the GPT Code Interpreter?

Yes, it evaluates scripts for sandbox compatibility and recommends which files should be uploaded as executable Python scripts versus instruction-based references.

How does it handle the 8,000-character instruction limit?

It employs a tiered condensation strategy, moving detailed procedures and examples into external knowledge files while keeping the core workflow and rules in the primary instructions.

Converts Claude Code Agent Skills into the OpenAI Custom GPT format while managing platform-specific constraints like character limits and file structures.

The OpenAI GPT Converter is a specialized utility designed to bridge the gap between Anthropic's Claude Code skills and OpenAI's Custom GPT ecosystem. It systematically audits existing SKILL.md files, condenses instructions to fit the 8,000-character limit, and maps complex hierarchical file structures to the flat format required by GPT knowledge files. By intelligently evaluating scripts for Code Interpreter compatibility and identifying API integration opportunities for GPT Actions, this skill ensures a seamless transition of agentic capabilities across platforms while maintaining high logic retention and operational performance.
