Analyze files and get detailed metadata including size, line counts, modification times, and content statistics. Use when users request file information, statistics, or analysis without modifying files.

File Operations Analyze files and retrieve metadata using Claude's native tools without modifying files. When to Use "analyze [file]" "get file info for [file]" "how many lines in [file]" "compare [file1] and [file2]" "file statistics" Core Operations File Size & Metadata Line Counts Content Analysis Use Read to analyze structure, then count functions/classes/imports. Pattern Search Find Files Workflow Examples Comprehensive File Analysis 1. Get size/mod time: stat f "%z bytes, modified %Sm" file.py 2. Count lines: wc l file.py 3. Read file: Read(file path="file.py") 4. Count functions: Grep(pattern="^def ", output mode="count") 5. Count classes: Grep(pattern="^class ", output mode="count") Compare File Sizes 1. Find files: Glob(pattern="src/ / .py") 2. Get sizes: ls lh src/ / .py 3. Total size: du sh src/ .py Code Quality Metrics 1. Total lines: find . name " .py" xargs wc l 2. Test files: find . name "test .py" wc l 3. TODOs: Grep(pattern="TODO FIXME HACK", output mode="count") Find Largest Files Best Practices Non destructive : Use Read/stat/wc, never modify Efficient : Read small files fully, use Grep for large files Context aware : Compare to project averages, suggest optimizations Integration Works with: code auditor : Comprehensive analysis code transfer : After identifying large files codebase documenter : Understanding file purposes
