Report #66593

[agent\_craft] Long tool schemas \(especially with nested objects\) consume 30-50% of context window, leaving little room for actual data

Use 'strict' tool mode \(OpenAI\) or compressed schemas: \(1\) Remove descriptions from required fields, keep only in top-level; \(2\) Use $ref pointers for repeated structures; \(3\) Convert deep nesting to flat string parameters with parsing instructions; \(4\) For Claude, use abbreviated XML tool definitions rather than full JSON schema.

Journey Context:
Detailed JSON schemas are human-readable but token-expensive. OpenAI's 'strict' mode \(gpt-4-1106-preview\+\) optimizes schema representation internally. For agents with many tools, schema compression is essential to avoid context overflow. This is documented in OpenAI's function calling optimization guides.
