How to write your own Claude skill from the template with Anthropic Skills

Start from the repo's template-skill, write a SKILL.md with the two required frontmatter fields and your instructions, and use it to teach Claude a task the same way every time.

Short answer: Copy the template-skill from the repo's ./template folder as your starting point; then create a folder for your skill with a SKILL.md file; add YAML frontmatter with the two required fields: name (a unique identifier, lowercase, hyphens for spaces) and description (what the skill does and when to use it). All steps.

Who it is forA team lead who wants Claude to follow the company's brand guidelines or a fixed workflow without re-explaining it.

The problemInstructions pasted into every chat drift and get forgotten between sessions.

The outcomeA self-contained skill folder with a SKILL.md that Claude loads when the task comes up.

What you need first

  • Claude Code to install the plugins (Claude.ai paid plans already include the example skills)
  • The Claude API only if you use pre-built or custom skills through the API
  • Many skills are Apache 2.0; the docx, pdf, pptx and xlsx skills are source-available, not open source

Steps

  1. Copy the template-skill from the repo's ./template folder as your starting point
  2. Create a folder for your skill with a SKILL.md file
  3. Add YAML frontmatter with the two required fields: name (a unique identifier, lowercase, hyphens for spaces) and description (what the skill does and when to use it)
  4. Below the frontmatter, write the instructions, examples and guidelines Claude should follow
  5. Upload it to Claude.ai following Using Anthropic Skills in Claude, or through the Claude API with the Skills API Quickstart

Prompt for your agent

Help me write a Claude skill using the template-skill from anthropics/skills. Create a folder with a SKILL.md whose YAML frontmatter has only name (lowercase, hyphens) and description (what it does and when to use it), then write clear instructions, examples and guidelines for this task: <describe the task>. Show me the file before saving it.

Caveat. The README points to How to create custom Anthropic Skills for full details; the README asks for a complete description of what the skill does and when to use it.
