This skill should be used when the user asks to create a new skill, build a skill, make a custom skill, develop a CLI skill, or wants to extend the CLI with new capabilities. Automates the entire skill creation workflow from brainstorming to installation.
默认使用会先检查来源的 Prompt；你也可以切换为直接命令，或下载本地副本。
决定是否安装前，请先阅读 SKILL.md，以及 SkillsMP 当前展示的配套文件。
用 Codex 或 Claude 帮你安装 复制这段 Prompt，粘贴到 Codex、Claude 或其他助手里，让它检查 Skill 页面并帮你完成安装。
直接命令不会经过审查 Prompt；运行前请先检查来源。
npx skills add https://github.com/baotoq/go-shortener --skill tools-skill-creator命令会保持在同一行。复制前请横向滚动并检查完整内容。
想先保存到本地？可下载 SkillsMP 当前能够提供的文件。

To create new CLI skills following Anthropic's official best practices with zero manual configuration. This skill automates brainstorming, template application, validation, and installation processes while maintaining progressive disclosure patterns and writing style standards.
This skill should be used when:

🚀 Next Steps:
1. Test the skill: Try trigger phrases in CLI
2. Add examples: Create working code samples in examples/
3. Extend docs: Add detailed guides to references/
4. Commit changes: git add .github/skills/your-skill-name && git commit
5. Share: Push to repository for team use
💡 Pro Tips:
- Keep SKILL.md under 2,000 words (currently: 1,847)
- Move detailed content to references/ folder
- Add executable scripts to scripts/ folder
- Update README.md with real usage examples
- Run validation before committing: scripts/validate-skill-yaml.sh
If platforms cannot be detected:
⚠️ Unable to detect GitHub Copilot CLI or Claude Code
Would you like to:
1. Install for repository only (works when in repo)
2. Specify platform manually
3. Skip installation
If templates are missing:
❌ Error: Template not found at resources/templates/
This skill requires the cli-ai-skills repository structure.
Options:
1. Clone cli-ai-skills: git clone <repo-url>
2. Create minimal skill structure manually
3. Exit and set up templates first
If content doesn't meet standards:
⚠️ Validation Issues Found:
1. YAML: Description not in third-person format
Expected: "This skill should be used when..."
Found: "Use this skill when..."
2. Content: Word count too high (5,342 words, max 5,000)
Suggestion: Move detailed sections to references/
Fix automatically? [Y/n]
If symlink already exists:
⚠️ Skill already installed at ~/.copilot/skills/your-skill-name
Options:
1. Overwrite existing installation
2. Rename new skill
3. Skip installation
4. Install to different location
