Reviewed exact head be9e82552bce54b1aefaa4c06e203680df9dc3ba. The destination scoping and fail-closed intent are reasonable, but this head is not merge-ready because the affected existing adapter suite is red.
Running bun test tests/xai-web-search-compat.test.ts tests/responses-routed-web-search-fields.test.ts tests/openai-responses-passthrough.test.ts produces 105 passes and 1 failure at tests/openai-responses-passthrough.test.ts:1008. The existing xAI passthrough case expects the top-level web_search with external_web_access:false to survive field stripping; this PR intentionally removes that tool entirely, so body.tools becomes undefined. The same test also carries an additional_tools live-search case whose expected shape no longer matches the new removal of search_context_size.
Please update the pre-existing regression to the new explicitly chosen semantics (including top-level and additional_tools plus tool_choice behavior), and keep one separate compatibility test proving non-xAI capability-classified gateways still use the generic field-strip path rather than this host-specific policy. Then rebase onto current dev and rerun the complete affected suite, typecheck, privacy scan, and exact-head CI. A current xAI Responses canary would also be valuable before merge because this changes live hosted-search semantics rather than only removing a rejected field.
Typecheck passes on this head, but the focused regression failure is a merge blocker.

Addressed the requested regression coverage on exact head
I did not run a live xAI Responses canary because that would use the user's account credentials/credits without separate authorization. The PR is now ready for re-review. |

existing OpenAI-only field removal logic to tools nested within
additional_tools, including removing search_context_size while preserving other
supported fields. Add a regression test covering a nested cached declaration for
a non-xAI provider with supportsOpenAiWebSearchToolFields set to false.

Approved exact head 64cd6e5a91a4498fa279ba15cf227155dfb4d1c2 after independently validating the owner/Grok and automated findings.
The previously failing passthrough contract is now updated, the generic non-xAI capability path strips only the private OpenAI fields across top-level and nested additional_tools, and xAI-only normalization is restricted to the exact public https://api.x.ai destination. Cached-only search remains fail-closed instead of widening to live search, web_search_preview declarations and selectors normalize to xAI public web_search, stale selectors are removed, and image-search intent maps to the documented xAI field.
Exact-head validation passed 109/109 focused tests, typecheck, privacy scan, and diff check. The branch is 0 behind current dev, and there are no unresolved review threads. Do not merge until exact-head cross-platform CI is fully green and the head remains unchanged. This scoped TypeScript adapter change has no current Go-runtime counterpart; record that explicit no-counterpart decision when integrating under the dev2-go transition policy.
