create-skill

create-skill is a skill for Claude Code, Codex from khanh-vu/claude-force. It costs 0 tokens per session (3,045 once invoked), scanned A, original, MIT.

Guidance and templates for creating skills that give coding agents repeatable instructions and examples.

In plain words
What is it for?
Use it to define a skill’s purpose, create its files and folders, document reusable patterns, add examples, and plan agent integration.
Why use it?
It turns an informal idea into a consistent structure that agents can use and maintain.

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

create-skill 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 5d 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.

Skill Creation Process

Step 1: Define Skill Purpose

Before creating a skill, clearly define:

  1. What: What capability does this skill provide?
  2. Why: Why is this skill needed?
  3. Who: Which agents will use this skill?
  4. When: In what scenarios is this skill used?
  5. How: What patterns/examples will it provide?

Step 2: Skill Directory Structure

Create a skill with this standard structure:

skill-name/
├── SKILL.md           # Main skill definition
├── README.md          # Overview and quick start
├── patterns/          # Reusable patterns (optional)
│   ├── pattern1.md
│   ├── pattern2.md
│   └── pattern3.md
└── examples/          # Example usage (optional)
    ├── example1.md
    └── example2.md

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.

create-skill is a skill published in the GitHub repository khanh-vu/claude-force (5 stars, last pushed 9mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,045 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
