Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

file-organizer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

File Organizer

This skill acts as your personal organization assistant, helping you maintain a clean, logical file structure across your computer without the mental overhead of constant manual organization.

When to Use This Skill

  • Your Downloads folder is a chaotic mess
  • You can't find files because they're scattered everywhere
  • You have duplicate files taking up space
  • Your folder structure doesn't make sense anymore
  • You want to establish better organization habits
  • You're starting a new project and need a good structure
  • You're cleaning up before archiving old projects

What This Skill Does

  1. Analyzes Current Structure: Reviews your folders and files to understand what you have
  2. Finds Duplicates: Identifies duplicate files across your system
  3. Suggests Organization: Proposes logical folder structures based on your content
  4. Automates Cleanup: Moves, renames, and organizes files with your approval
  5. Maintains Context: Makes smart decisions based on file types, dates, and content
  6. Reduces Clutter: Identifies old files you probably don't need anymore

How to Use

From Your Home Directory

cd ~

Then run Claude Code and ask for help:

Help me organize my Downloads folder
Find duplicate files in my Documents folder
Review my project directories and suggest improvements

Specific Organization Tasks

Organize these downloads into proper folders based on what they are
Find duplicate files and help me decide which to keep
Clean up old files I haven't touched in 6+ months
Create a better folder structure for my [work/projects/photos/etc]

Instructions

When a user requests file organization help:

  1. Understand the Scope

    Ask clarifying questions:

    • Which directory needs organization? (Downloads, Documents, entire home folder?)
    • What's the main problem? (Can't find things, duplicates, too messy, no structure?)
    • Any files or folders to avoid? (Current projects, sensitive data?)
    • How aggressively to organize? (Conservative vs. comprehensive cleanup)
