FileTools now supports delete, chunked read, and partial replace operations, with new size limits and base_dir disclosure controls. This lets teams handle large files efficiently while enforcing stricter boundaries to reduce data leakage risks.

**Details**

- Chunked reads improve performance and memory usage for large files
- Partial replace enables targeted edits without full rewrites
- Configurable size limits and directory scoping enforce policy and reduce risk
- Additive update; existing workflows continue to work unchanged

**Who this is for:** Platform and operations teams processing files within agents and workflows at scale.
