Constant Summary collapse

UNSUPPORTED_KEYS =

Anthropic's strict schema subset rejects these validation constraints. They are removed from the wire schema and folded into the property's description so the model still sees them. The caller's original schema remains unchanged and can still be used locally.

minLength, maxLength, and pattern are deliberately absent: the API accepts all three on both the strict-tool and native structured-output paths, so removing them would trade real constrained-decoding enforcement for a description the model may ignore. Verified against claude-opus-4-8.

WIRE_MIN_ITEMS_MAX =

The strict subset does support minItems values of 0 and 1, so instead of dropping the constraint entirely, larger bounds are clamped to 1 -- the API then rejects empty arrays via constrained decoding, and the real bound rides in the description and the caller's local validation.
