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 C, and why

basics scanned grade C with 1 finding 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.

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

The opening of the file, as written. The whole thing — 628 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Git Basics

Parent Skill: /git Path: /git/basics

Purpose

Master Git fundamentals including repository initialization, commits, basic workflows, and .gitignore configuration. This is the foundation for all Git operations.

When to Use

Trigger automatically when:

  • User mentions: init, clone, commit, add, status, push, pull, .gitignore
  • First-time Git setup
  • Basic commit workflow questions
  • Configuration issues
  • New repository creation

Chat commands:

/git/basics initialize new repository
/git/basics help me commit my changes
/git/basics create .gitignore for Node.js project
/git/basics configure git with my name and email
/git/basics what's the basic workflow

Requirements

Verification

# Check Git installation
git --version

# Check configuration
git config --global --list

# Test repository access
git status

Critical Rules


Basic Workflow

The Three States of Files

Working Directory → Staging Area (Index) → Repository (History)
     (modified)         (staged)              (committed)
         ↓                  ↓                      ↓
    git add           git commit              git push

Patterns

Pattern 1: Initialize New Repository

Problem: Starting a new project with Git version control

# ❌ BAD: Initialize in wrong directory
cd /
git init  # Don't do this!

# ✅ GOOD: Initialize in project directory
cd ~/projects/my-app
git init
git add .
git commit -m "Initial commit"

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

basics is a skill published in the GitHub repository nguyenthanhtat/screen1-claude (2 stars, last pushed 3mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,428 tokens. A static security scan graded it C with 1 finding (reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
