Skill Creator

Create and iteratively improve skills through evaluation, scoring, and description optimization.

About Skills

Skills are modular, self-contained packages that extend Claude's capabilities with specialized knowledge, workflows, and tools. They transform Claude from a general-purpose agent into a specialized one equipped with procedural knowledge.

What Skills Provide

1. Specialized workflows — Multi-step procedures for specific domains
2. Tool integrations — Instructions for working with specific file formats or APIs
3. Domain expertise — Company-specific knowledge, schemas, business logic
4. Bundled resources — Scripts, references, and assets for complex and repetitive tasks

Core Principles

Concise is Key

The context window is a public good shared with system prompt, conversation history, other skills' metadata, and the user request.

Default assumption: Claude is already very smart. Only add context Claude doesn't already have. Challenge each piece of information: "Does Claude really need this?" and "Does this paragraph justify its token cost?"

Set Appropriate Degrees of Freedom

• High freedom (text-based instructions): Multiple approaches valid, decisions depend on context
• Medium freedom (pseudocode/scripts with parameters): Preferred pattern exists, some variation acceptable
• Low freedom (specific scripts, few parameters): Operations fragile, consistency critical

Anatomy of a Skill

skill-name/
├── SKILL.md (required)
│   ├── YAML frontmatter (name + description required)
│   └── Markdown instructions
└── Bundled Resources (optional)
    ├── scripts/      — Executable code
    ├── references/   — Documentation loaded into context as needed
    └── assets/       — Files used in output (templates, icons, fonts)

SKILL.md (required)

• Frontmatter (YAML): name and description fields. These determine when the skill triggers — be clear and comprehensive.
• Body (Markdown): Instructions loaded AFTER the skill triggers.
