At a glance

Analyze files and get detailed metadata including size, line counts, modification times, and content statistics.

  • Works in 5 steps: Get size/mod time: stat -f "%z bytes,… → Count lines: wc -l file.py → Read file: Read(file_path="file.py") → …
  • Users request file information
  • SKILL.md covers When to Use, Core Operations, Workflow Examples and Best Practices, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

File Operations is an agent skill from mhattingpete/claude-skills-marketplace. 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.

Its SKILL.md is about 640 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Data & Analytics, covering Statistics. The repository describes itself as: Claude Code Skills for software engineering workflows - Git automation, testing, and code review. The licence is Apache-2.0.

When your agent uses it

  • Users request file information
  • Analysis without modifying files

Example prompts

  • “/file-operations”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  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")

What it can do on your machine

Read from SKILL.md and the folder at commit b5b34bc. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

File Operations loads about 635 tokens when it runs. Until then it costs about 55 tokens; SKILL.md has 177 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~635

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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

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
Find Files
Glob(pattern="**/*.py")

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
bash
find . -type f -not -path "./node_modules/*" -exec du -h {} + | sort -rh | head -20

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
