File Access Toolset¶

The File Access toolset provides tools for reading, writing, and editing files on any fsspec-compatible filesystem. This includes local files, S3, GitHub repositories, and more.

Basic Usage¶

agents:
  my_agent:
    toolsets:
      - type: file_access
        fs: "file:///workspace"

Filesystem Options¶

The fs field accepts either a URI string or a full filesystem configuration:

URI String¶

toolsets:
  - type: file_access
    fs: "file:///home/user/project"

Filesystem Config¶

toolsets:
  - type: file_access
    fs:
      type: github
      org: sveltejs
      repo: svelte
      sha: main

Composed Filesystems¶

Mount multiple filesystems together using the mounts type:

toolsets:
  - type: file_access
    fs:
      type: mounts
      mounts:
        docs: "github://sveltejs:svelte@main"
        src: "file:///workspace/src"
        data:
          type: s3
          bucket: my-bucket

Available Tools¶

The toolset provides these tools to agents:

Tool	Description
`list_directory`	List files with glob patterns and filtering
`read_file`	Read file contents (text or binary/images)
`write_file`	Write content to files
`edit_file`	Smart find-and-replace editing
`delete_path`	Delete files or directories
`grep`	Search file contents with regex
`agentic_edit`	AI-powered file editing
`download_file`	Download files from URLs

Configuration Reference¶

File Access Toolset¶

Configuration for file access toolset (supports local and remote filesystems).

File Access Toolset (YAML)
toolsets:
- type: file_access
  fs: null  # Filesystem URI string or configuration object. If None, use agent default FS.
  model: null
  storage_options: {}  # Additional options for URI-based filesystems (ignored when using config object).
  conversion: null  # Optional conversion configuration for markdown conversion.
  max_file_size_kb: 64  # Maximum file size in kilobytes for read/write operations (default: 64KB).
  max_grep_output_kb: 64  # Maximum grep output size in kilobytes (default: 64KB).
  use_subprocess_grep: true  # Use ripgrep/grep subprocess if available (faster than Python regex).
  namespace: null  # Optional namespace prefix for tool names

Examples¶

Local Development¶

toolsets:
  - type: file_access
