skill-create

skill-create is a command for Claude Code from sumulige/sumulige-claude. It costs 6 tokens per session (567 once invoked), scanned A, original, MIT.

A command that creates the starter files for a new coding-agent skill, including instructions, metadata, examples, and templates. It also adds the skill to the project's search index.

In plain words
What is it for?
Use it when creating a skill by providing its name, description, category, difficulty, triggers, and related configuration.
Why use it?
It removes the repetitive setup work involved in defining a skill and helps keep its documentation and metadata in the expected structure.

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

skill-create 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 3d 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.

What it actually says

Create a new skill using the standard template.

Step 1: Get Skill Information

Ask the user for:

  1. Skill name (kebab-case, e.g., code-reviewer)
  2. Description (one-line summary)
  3. Category (development, design, analysis, workflow, etc.)
  4. Difficulty (beginner, intermediate, advanced)

Step 2: Create Skill Directory

Create the skill directory structure:

mkdir -p .claude/skills/{skill-name}/{templates,examples}

Step 3: Generate SKILL.md

Use this template:

# {Skill Name}

> {Description}

**版本**: 1.0.0
**作者**: AI
**标签**: [{category}]
**难度**: {difficulty}

---

## 概述

{Detailed description of what this skill does}

## 适用场景

- {Scenario 1}
- {Scenario 2}
- {Scenario 3}

## 触发关键词

{trigger keywords}


## 使用方法

### 基础用法

{Example usage}

## 输出格式

{Output format description}

## 注意事项

- {Note 1}
- {Note 2}

## 相关技能

- [Related Skill](../related-skill/)

## 更新日志

### 1.0.0 ({current-date})
- 初始版本

Step 4: Generate metadata.yaml

name: {skill-name}
version: 1.0.0
author: AI
description: {description}

tags:
  - {category}

triggers:
  - {trigger1}
  - {trigger2}

dependencies: []
difficulty: {difficulty}

Step 5: Add to RAG Index

Update .claude/rag/skill-index.json:

{
  "skills": [
    {
      "name": "{skill-name}",
      "description": "{description}",
      "keywords": ["{trigger1}", "{trigger2}"],
      "path": ".claude/skills/{skill-name}/SKILL.md"
    }
  ]
}

Step 6: Verify

Confirm with user:

  • Skill created at .claude/skills/{skill-name}/
  • Added to RAG index
  • Ready to use

Example

User: "Create a skill called api-tester for testing REST APIs"

→ Create .claude/skills/api-tester/ with:

  • SKILL.md (filled with API testing content)
  • metadata.yaml
  • templates/request.md
  • examples/basic-test.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.
