Detailed Tool Comparisons

File Reading Capabilities

Cursor: read_file

{
  target_file: string,        // Relative or absolute path
  offset?: integer,            // Line to start from
  limit?: integer,             // Number of lines
}

Features:

• Can read images (PNG, JPG, etc.)
• Outputs with line numbers (1-indexed)
• Warns if file is empty
• Supports pagination for large files

Format: LINE_NUMBER|LINE_CONTENT

Claude Code: Read

{
  file_path: string,           // Absolute path only
  offset?: number,             // Line offset
  limit?: number,              // Lines to read
}

Features:

• Reads images (PNG, JPEG, GIF)
• Reads PDFs (page by page)
• Reads Jupyter notebooks
• Default 2000 line limit
• Truncates lines > 2000 chars

Format: cat -n style with line numbers

Augment: view

{
  path: string,                // Relative to workspace
  type: 'file' | 'directory',
  view_range?: [number, number], // Line range
  search_query_regex?: string,   // Optional regex search
  context_lines_before?: number,
  context_lines_after?: number,
}

Features:

• Combined file and directory view
• Integrated regex search
• Contextual line display
• Directories show 2-level tree

Unique: Search within read operation

Amp: Read

{
  path: string,                // Absolute path
  read_range?: [number, number] // [start, end] lines
}

Features:

• Reads images visually
• Default first 1000 lines
• Line numbers prefixed
• Parallel reading encouraged

Format: 1: content style

File Editing Approaches

Cursor: Sketch-Based (edit_file)

Philosophy: High-level instructions with AI filling gaps

{
  target_file: string,
  instructions: string,    // Single sentence description
  code_edit: string,       // Sketch with "// ... existing code ..."
}

Example:

// ... existing code ...
function calculateTotal(items) {
  return items.reduce((sum, item) => sum + item.price, 0);
}
// ... existing code ...

Advantages:

• Less verbose
• Faster to write
• AI interprets intent

Disadvantages:

• Can misinterpret
• Less precise control
• May need reapply tool

Claude Code: Exact Replacement (Edit)

Philosophy: Precise string matching

{
  file_path: string,
  old_string: string,      // Must match exactly
  new_string: string,
  replace_all?: boolean,   // Default: false
}

Requirements:

• Must read file first
• old_string must be unique (unless replace_all)
• Preserves indentation exactly
• Fails if not found

Advantages:

• Predictable
• No ambiguity
• Explicit changes

Disadvantages:

• Verbose for large changes
• Exact matching required
• More tokens

Augment: Line-Scoped (str-replace-editor)

Philosophy: Line numbers + exact matching

{
  command: 'str_replace',
  path: string,
  old_str_1: string,
  new_str_1: string,
  old_str_start_line_number_1: number,
  old_str_end_line_number_1: number,
  // Multiple edits: old_str_2, new_str_2, etc.
}

Features:

• Multiple edits in one call
• Line ranges for disambiguation
• Max 150 lines per edit
• Both line numbers INCLUSIVE

Advantages:

• Handles multiple occurrences
• Clear scope
• Batch editing

Disadvantages:

• More parameters
• Line number tracking
• Complexity increases

Amp: Flexible (edit_file + create_file)

Philosophy: Choose best tool for task

// For targeted changes
edit_file({
  path: string,
  old_str: string,
  new_str: string,
  replace_all?: boolean
});

// For full file replacement
create_file({
  path: string,
  content: string
});

Strategy:

• Whole file replace → create_file
• Small targeted change → edit_file
• Multiple similar changes → replace_all

Advantages:

• Optimal for each scenario
• Less redundant content
• Flexible approach
