There was a problem hiding this comment.
might be nice to add some unit tests so that this doesn't regress in the future?

…ecution` tool dynamic calls from latest `web_fetch` or `web_search` (#15566) ## Background When Anthropic's `web_fetch` or `web_search` tools internally trigger code execution, the API emits `code_execution` tool calls even though the user did not register that tool. The fix from #12668 marked such calls as `dynamic: true` to bypass validation, but several code paths in the Anthropic language model still emitted unmarked calls, causing errors. The newer `code_execution_20250825` tool variant also surfaces calls under sub-names (`bash_code_execution`, `text_editor_code_execution`) that need the same treatment. ## Summary - Mark `code_execution` tool calls as `dynamic` in all remaining emission sites for the 20250825 tool variant (non-streaming `bash_code_execution`/`text_editor_code_execution` branch, streaming first-delta and end paths, and streaming `tool-call` finalization). - Normalize the streaming delta path to use the unified `code_execution` provider tool name and consistently backfill input with `"type": "programmatic-tool-call"` so downstream consumers see a consistent shape. - Only set `firstDelta: true` when no input has been buffered yet, avoiding double-prefixing. This was not surfacing in a real bug so far, but it was clearly also an oversight (per `firstDelta: true` only ever being okay if there was no input yet on that same chunk). ## Manual Verification Run the existing examples: - `examples/ai-functions/src/stream-text/anthropic/web-fetch-20260209-pdf.ts` - `examples/ai-functions/src/stream-text/anthropic/web-fetch-20260209-pdf.ts` Without this PR, they will somewhere in the stream include the error about an incompatible tool being found, most times when executing them. With this PR, this error is gone from both. ## Checklist - [x] All commits are signed (PRs with unsigned commits cannot be merged) - [ ] Tests have been added / updated (for bug fixes / features) - [ ] Documentation has been added / updated (for bug fixes / features) - [x] A _patch_ changeset for relevant packages has been added (for bug fixes / features - run `pnpm changeset` in the project root) - [x] I have reviewed this pull request (self-review)
