Core Features & Capabilities

1. Fundamental Filesystem Operations

File Operations

// Read text and binary files with intelligent encoding
read_file(path: String, encoding: Option<String>) -> FileContent

// Write files with human approval workflow
write_file(path: String, content: String, create_directories: bool) -> WriteResult

// Atomic file operations for safety
move_file(source: String, destination: String) -> MoveResult
copy_file(source: String, destination: String) -> CopyResult
delete_file(path: String) -> DeleteResult

Directory Operations

// Efficient directory listing with metadata
list_directory(path: String, recursive: bool, include_hidden: bool) -> DirectoryListing

// Directory management with permission checking
create_directory(path: String, recursive: bool) -> CreateResult
delete_directory(path: String, recursive: bool) -> DeleteResult

2. Security-First File Processing

Binary File Restriction

  • Complete Binary Blocking: All binary file operations are disabled for maximum security
  • Text-Only Processing: Focus on development files like source code, configuration, and documentation
  • Attack Surface Reduction: Eliminates entire classes of binary-based security vulnerabilities
  • Memory Safety: Prevents buffer overflows and memory corruption from binary parsing
  • Malware Prevention: Blocks execution of potentially malicious binary content

Supported Text File Types

  • Source Code: .rs, .py, .js, .ts, .java, .cpp, .c, .go, etc.
  • Configuration: .toml, .json, .yaml, .yml, .ini, .conf, etc.
  • Documentation: .md, .txt, .rst, .adoc, .tex, etc.
  • Data Files: .csv, .log, .sql, .xml, .html, etc.
  • Web Files: .css, .scss, .less, .vue, .svelte, etc.

Binary File Detection

  • Extension-Based Validation: Comprehensive list of known binary extensions
  • Content-Based Detection: Analysis of file content to identify binary data
  • Magic Number Recognition: Detection of binary file signatures
  • Audit Logging: Comprehensive logging of all binary file rejection events

3. Security & Access Control

Multi-Layer Security Architecture

// Configuration-driven security policies
SecurityPolicy {
    allowed_read_paths: Vec<PathBuf>,
    allowed_write_paths: Vec<PathBuf>,
    forbidden_patterns: Vec<Regex>,
    max_file_size_mb: u64,
    require_approval_for_writes: bool,
    require_approval_for_deletes: bool,
}

Human-in-the-Loop Workflows

  • Write Operation Approval: Interactive confirmation for file creation/modification
  • Dangerous Operation Protection: Special approval for deletions, moves, executable files
  • Path Validation: Prevent directory traversal and unauthorized access
  • Operation Auditing: Comprehensive logging of all filesystem interactions

Risk-Based Controls

  • File Type Restrictions: Configurable policies for different file types
  • Size Limitations: Prevent resource exhaustion from large file operations
  • Rate Limiting: Prevent abuse through excessive operation requests
  • Quarantine Mode: Safe handling of potentially dangerous files
