Report #94101

[agent\_craft] System prompt exceeds token limit with full OpenAPI specs for tool definitions

Distill tool descriptions to 'Purpose \+ 3 critical params' and omit enum lists >20 items; force the model to ask for clarification on edge cases.

Journey Context:
Full OpenAPI schemas can consume 500-2000 tokens per tool, eating the context window before any user input. The model rarely needs full enum lists or deeply nested object details to decide to use a tool. By distilling to the decision-critical information, you reduce the cognitive load and token cost. The model can request specific enum values or nested fields in a follow-up turn when actually executing, which is cheaper than upfront bloat.
