Create Skill Skill

Create new Claude Code agent skills that Claude invokes autonomously based on task context.

Skill Structure

Each skill lives in its own folder within skills/:

Copyskills/
└── skill-name/
    ├── SKILL.md              # Main skill definition (required)
    ├── examples/             # Example files (optional)
    │   └── example.md
    └── templates/            # Templates (optional)
        └── template.md

SKILL.md Format

Copy---
name: skill-name
short: Brief 5-8 word summary (optional)
description: When and how Claude should use this skill. Be specific about triggers and use cases.
when: Semantic activation trigger for index display (optional)
---

# Skill Title

Detailed instructions for how to apply this skill...

Required Frontmatter Fields

Optional Frontmatter Fields

Note: short and when are used for forge-index display. The description field is used by Claude Code for skill invocation.

Writing Effective Descriptions

The description is critical - it tells Claude when to use the skill. Include:

1. Trigger conditions: When should this skill activate?
2. Use cases: What tasks benefit from this skill?
3. Scope: What does and doesn't this skill cover?

Good Description Examples

Copydescription: Apply React best practices when creating or modifying React components. Use for hooks, state management, component structure, and performance optimization.

Copydescription: Enforce security best practices when writing code that handles user input, authentication, or sensitive data. Covers input validation, SQL injection prevention, and XSS protection.

Copydescription: Generate API documentation when creating or updating REST endpoints. Produces OpenAPI-compatible documentation with examples.

Bad Description Examples

Copy# Too vague - Claude won't know when to use it
description: Helps with Python code

Copy# Too broad - will trigger too often
description: Use this for all coding tasks

Skill Body Content

The body should include:

1. Context: Background information Claude needs
2. Rules/Guidelines: Specific practices to follow
3. Examples: Concrete examples of correct usage
4. Anti-patterns: What to avoid
5. Output format: How to present results

Example Skill

    ├── SKILL.md
    ├── examples/
    │   ├── rest-example.md
    │   └── graphql-example.md
    └── templates/
        └── openapi-template.yaml

Reference these in your SKILL.md:
