…in-ai#3630) Closes langchain-ai#3568 --- Tool description and system-prompt examples for `read_file` showed the kwarg as `path` (`read_file(path, limit=100)`) while the underlying `ReadFileSchema` requires `file_path`. Frontier models tolerate the contradiction by deferring to the schema; open-weight models (qwen3, gemma4) copy the example verbatim and every call fails with `file_path: Field required`. ## Changes - Rewrite the three text-mode example signatures in `READ_FILE_TOOL_DESCRIPTION` to `read_file(file_path="...", …)`, matching the multimodal example already present. - Update the workflow line in `SKILLS_SYSTEM_PROMPT` (`SkillsMiddleware`) to use `read_file(file_path="...", limit=1000)`. - Apply the same fix to `deepagents-code`'s `system_prompt.md` and the `format_tool_display` docstring example.
