Tools sourced from MCP servers and OpenAPI-derived gateways (AWS
AgentCore + Google Workspace, DevRev MCP, etc.) frequently carry
JSON Schemas backed by legacy ``definitions`` (draft-04) or OpenAPI
``components.schemas`` instead of ``$defs`` (JSON Schema 2020-12).
Anthropic and Fireworks only resolve ``$defs``. Their tool-schema
filters silently drop the unrecognised def blocks while keeping the
``$ref`` pointers, so the upstream rejects the request:
- Anthropic: ``tools.0.input_schema: Invalid tool schema, $ref is
not supported``
- Fireworks: ``Error resolving schema reference '#/definitions/...'``
(PointerToNowhere)
Add ``unpack_legacy_defs(schema, *, copy=False)`` next to the existing
``unpack_defs`` -- a single helper that pops draft-04 ``definitions``
and OpenAPI ``components.schemas`` and feeds them through
``unpack_defs`` in place. ``$defs`` is left untouched (resolved
natively). ``copy=True`` deep-copies first when there is actually work
to do, used by Anthropic so the caller's tool dict is preserved.
Anthropic ``_map_tool_helper`` calls ``unpack_legacy_defs(_, copy=True)``;
Fireworks ``_transform_tools`` calls ``unpack_legacy_defs(params)``
in place.

In total litellm runs 1000+ tests
[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/test_litellm
This folder can only run mock tests.
