Upgrade Anthropic code execution support from the legacy `code_execution_20250522` to the latest `code_execution_20260120` version, unblocking features like custom file uploads to containers.
### Description From what I can tell, the current code execution support for Anthropic uses the now legacy `code_execution_20250522` version. Per [Anthropic](https://platform.claude.com/docs/en/agents-and-tools/tool-use/code-execution-tool#upgrade-to-latest-tool-version), the latest is `code_execution_20260120`. This would also unblock features like custom file uploads to containers, which is blocked on `code_execution_20250825`: https://platform.claude.com/docs/en/agents-and-tools/tool-use/code-execution-tool#upload-and-analyze-your-own-files ### References https://platform.claude.com/docs/en/agents-and-tools/tool-use/code-execution-tool#upgrade-to-latest-tool-version https://platform.claude.com/docs/en/agents-and-tools/tool-use/code-execution-tool#upload-and-analyze-your-own-files https://github.com/search?q=repo%3Apydantic%2Fpydantic-ai+code_execution_2025&type=code
