Security Notes
The server implements robust security measures including path validation (`_secure_resolve`) to prevent directory traversal, file size limits to mitigate resource exhaustion, and atomic writes for file modifications. It also uses temporary files for external tool inputs to reduce command injection risk. However, it relies heavily on executing external CLI tools (`ast-grep`, `ripgrep`, `ruff`, `eslint`) via `subprocess.run` and performs extensive file system operations for code editing. While inputs are processed with security in mind, the broad attack surface of these capabilities necessitates careful management of the `WORKSPACE_ROOT` environment variable and an understanding of the tools' invocation context.
