Code Review
This pull request introduces new filesystem tools—ReadFileTool, FileEditTool, and GrepTool—and updates the local and sandbox booters to support these operations. It also implements a security layer to restrict file access for non-admin users in local environments. The review feedback highlights potential memory issues when reading or editing large files in their entirety and suggests applying the documented default limit for file reads to prevent excessive memory consumption.

Reading the entire file into memory using f.read() is inefficient and risky for large files, potentially leading to Out-Of-Memory (OOM) errors. Since the tool supports offset and limit, consider reading the file in chunks or using f.seek() if the encoding allows, to only load the required portion of the file.

This implementation reads the full content of the file from the sandbox into the bot's memory before slicing. This is inefficient for large files. If the Shipyard Neo SDK supports range-based reads, they should be used here to fetch only the requested slice.

Similar to read_file, reading the entire file into memory for string replacement can be problematic for large files. For better scalability, consider processing the file line-by-line or in chunks and writing to a temporary file.

Joining all search results into a single string without any limit can consume significant memory if there are many matches. It would be safer to pass a result limit to the search function or truncate the results before joining.

The limit parameter in ReadFileTool is documented to default to 4000, but this default is not applied in the validation logic. If the LLM does not provide a limit, the booter will receive None and attempt to read the entire file. Applying the default here ensures consistent behavior and protects against large reads.
