Skill Conventions

File Format

Each skill file uses YAML frontmatter:

---
name: skill-name
description: What this skill does. When to use it.
allowed-tools: Tool1, Tool2  # Optional
---

# Skill Content

Naming

• Use lowercase with hyphens: my-skill-name
• Max 64 characters
• Be specific: rust-error-handling not errors

Description Guidelines

The description field drives auto-activation. Include:

1. What the skill does
2. When Claude should use it
3. Trigger keywords users would mention

# Good
description: Debug Rust compile errors and borrow checker issues. Use when encountering lifetime errors, ownership problems, or type mismatches.

# Bad
description: Helps with Rust

Skill Discovery

Claude automatically discovers skills based on:

• Task relevance
• Description keywords
• Request context

No explicit invocation needed—write good descriptions and Claude will find them.
