Research direction

Review the current includeSchema and JsonSchema API in the Java SDK, then compare them with the linked Google Schema reference and GhidraMCP builder. A complete contribution would first establish an agreed scope for a less-lax schema model and compatibility expectations for Gemini and OpenAI.

Description

enhancement needs confirmation waiting for user

Hopefully this is appropriate, prior, we were able to provide just a string to the includeSchema portion. Though I do like the approach of a type being passed now, I feel like the current JsonSchema object is too lax and doesnt really capture the needs. While working on my mcp server, I figured out that the best schema to provide was to just use the least common denominator approach, which is to use https://ai.google.dev/api/caching#Schema as the basis. Even though OpenAI's schema is better and does work for those llms that support it, gemini didnt conform to it well because it uses its own schema spec. So I built my own builder https://github.com/themixednuts/GhidraMCP/tree/main/src/main/java/com/themixednuts/utils/jsonschema

Is this something we can move towards?
