Does it preserve my Model Context Protocol (MCP) settings?

Yes, it automatically transforms MCP server paths and handles environment variable mapping to ensure server configurations work on the target platform.

How does it handle tool restriction differences?

It performs logic inversion, converting Claude's whitelist-style 'allowed-tools' into Gemini's blacklist-style 'excludeTools' and vice versa.

Is the conversion process destructive?

No, Skill Porter is designed to be non-destructive, typically creating new configuration files rather than overwriting your source code.

Can I create a single skill that works on both platforms?

Yes, Skill Porter can generate a universal structure containing both SKILL.md and gemini-extension.json files for dual-platform compatibility.
