3333 details:
3434 - Every supported model accepts all three [tool versions](https://platform.claude.com/docs/en/agents-and-tools/tool-use/code-execution-tool#tool-versions). On Claude Haiku 4.5, programmatic tool calling and REPL state persistence aren't available, so the newer versions behave like `code_execution_20250825` there.
