Claude Code Built-in Tools

Reading Files

Read Tool: Read file contents

Read file_path="/path/to/file.txt"

Options:

• offset: Start line (for large files)
• limit: Number of lines to read

Finding Files

Glob Tool: Find files by pattern

Glob pattern="**/*.ts"

Common patterns:

• **/*.ts - All TypeScript files
• src/**/*.tsx - React components in src
• **/test*.js - Test files anywhere

Searching Content

Primary Search: Use pnpm search:code "query" or Skill({ skill: 'ripgrep' }) for content searching. The built-in Grep tool is fallback-only.

Grep Tool: Search file contents (fallback only — prefer pnpm search:code or ripgrep skill first)

Grep pattern="function myFunc" path="/src"

Options:

• output_mode: "content", "files_with_matches", or "count"
• -A, -B, -C: Context lines

Writing Files

Write Tool: Create or overwrite files

Write file_path="/path/to/file.txt" content="..."

Edit Tool: Modify existing files

Edit file_path="/path/to/file.txt" old_string="..." new_string="..."

Directory Operations

Bash Tool: For directory operations

# List directory
ls -la /path/to/dir

# Create directory
mkdir -p /path/to/new/dir

# Move/rename
mv /old/path /new/path
