File Operations

This is your go-to for non-destructive file analysis when you need metadata without touching the actual files. It wraps stat, wc, du, and grep commands to pull line counts, file sizes, modification times, and content patterns. Honestly the workflow examples are the most useful part here, showing you how to chain operations for things like comprehensive file analysis or finding your largest files. It's positioned as a complement to heavier skills like code-auditor, giving you quick stats before you decide whether deeper analysis is worth it. The pattern search stuff using Grep to count functions or find TODOs is solid for quick code quality checks without spinning up a full linter.

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

stat -f "%z bytes, modified %Sm" [file_path]  # Single file
ls -lh [directory]                             # Multiple files
du -h [file_path]                              # Human-readable size

Line Counts

wc -l [file_path]                              # Single file
wc -l [file1] [file2]                          # Multiple files
find [dir] -name "*.py" | xargs wc -l          # Directory total

Content Analysis

Use Read to analyze structure, then count functions/classes/imports.

Pattern Search

Grep(pattern="^def ", output_mode="count", path="src/")        # Count functions
Grep(pattern="TODO|FIXME", output_mode="content", -n=true)    # Find TODOs
Grep(pattern="^import ", output_mode="count")                 # Count imports
