Resolves the silent strip of Anthropic Structured Outputs across the Vertex AI Claude transformation paths and the Anthropic-adapter re-merge. Consolidates and supersedes four stalled community PRs addressing overlapping aspects of the same root bug: - #23475 (Vertex AI Claude blanket-strip removal) - #23396 (Vertex AI Claude conditional passthrough) - #23706 (Anthropic adapter exclude output_config from non-Anthropic backends) - #22727 (Anthropic adapter strip output_config for non-Anthropic backends) Closes / addresses: #23380 (Vertex AI Claude output_config drop), related: #26423, #25079, #24549, #25971, #25957, #26163, #24856. What was broken --------------- * Vertex AI Claude paths called ``data.pop("output_config")`` and ``data.pop("output_format")`` unconditionally even when Vertex accepted those fields. Callers asking for Structured Outputs got a 200 with prose and never knew the schema constraints had been silently dropped (often masked for months by permissive fallback parsers). * The ``/v1/messages`` -> ``/chat/completions`` adapter (``LiteLLMMessagesToCompletionTransformationHandler``) re-merged the raw Anthropic-shaped ``output_config`` into ``completion_kwargs`` AFTER the translator already mapped its meaningful parts to ``response_format`` / ``reasoning_effort``. Non-Anthropic backends (Azure OpenAI, Fireworks, Bedrock Nova, etc.) then 400'd with "Extra inputs are not permitted". Approach -------- Vertex AI Claude (chat-completion + experimental_pass_through paths): Replace the unconditional pop with a sanitizer ``_sanitize_vertex_anthropic_output_params`` that strips only the Vertex-unsupported keys (today: ``effort``) from ``output_config`` while forwarding ``format`` and the legacy top-level ``output_format``. Defensive: non-dict ``output_config`` values are dropped to avoid sending malformed payloads downstream. Greptile P1 from PR #23396 addressed: when ``output_config`` carries both ``format`` and ``effort``, the prior conditional pass-through forwarded ``effort`` and reproduced the 400. The new helper filters per-key. Anthropic ``/v1/messages`` adapter: Add ``output_config`` to a named module-level constant ``ANTHROPIC_ONLY_REQUEST_KEYS`` and wire it into ``excluded_keys`` so the post-translation re-merge skips re-adding the raw key. This fixes the 400 on non-Anthropic backends and avoids the conflicting duplicate (``response_format`` + raw ``output_config``) on Anthropic-family backends. Greptile P2 from PR #23706 addressed: the constant gives reviewers one grep target instead of an inline literal that silently grows. Greptile P2 from PR #22727 addressed: ``extra_kwargs or {}`` is replaced with explicit ``is None`` checks so empty-dict callers no longer skip the fallback path. Tests ----- * tests/test_litellm/llms/vertex_ai/vertex_ai_partner_models/anthropic/ test_vertex_ai_partner_models_anthropic_transformation.py: - 5 new/updated cases plus a direct unit test for ``_sanitize_vertex_anthropic_output_params``. - Updated ``test_vertex_ai_claude_sonnet_4_5_structured_output_fix`` so its mock-injected ``output_format`` is asserted to FLOW THROUGH (the original test asserted the now-buggy strip behavior). * tests/test_litellm/llms/anthropic/experimental_pass_through/ adapters/test_handler_output_config_passthrough.py (new): - Constant export sanity, output_config strip with ``effort`` only, output_config strip with ``format`` only, regression guard that unrelated extras still flow, explicit-empty-dict path, and the ``extra_kwargs=None`` no-crash path. Test-quality fixes incorporated from Greptile review on the superseded PRs: * No ``inspect.getsource`` source-text assertions (PR #24114 / #23475). * ``sys.path`` insertion is anchored to ``__file__`` (PR #23706). * Assertion messages are positional, not tuple (PR #24114-class bug). * No ``or {}`` masking explicit empty dicts in helper signatures (PR #22727). Verified locally: 26/26 pass with this commit. The new tests fail (or fail to import) on ``main`` without it. Out of scope ------------ * The ``max_tokens`` capping logic from PR #22727 — independent concern, deserves its own PR with a focused test plan. * Architectural rework of the ``excluded_keys`` mechanism (Greptile P2 on PR #23706 noted point-fix growth). The named constant gives maintainers a clear place to extend; a registry-based approach would be a follow-up.

Testing for litellm/
This directory 1:1 maps the the litellm/ directory, and can only contain mocked tests.
The point of this is to:
- Increase test coverage of
litellm/ - Make it easy for contributors to add tests for the
litellm/package and easily run tests without needing LLM API keys.
