# Skill Creator
|
|
|
|
This skill provides guidance for creating effective skills.
|
|
|
|
## About Skills
|
|
|
|
Skills are modular, self-contained packages that extend Claude's capabilities by providing
|
|
specialized knowledge, workflows, and tools. Think of them as "onboarding guides" for specific
|
|
domains or tasks—they transform Claude from a general-purpose agent into a specialized agent
|
|
equipped with procedural knowledge that no model can fully possess.
|
|
|
|
### 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. Skills share the context window with everything else Claude needs: system prompt, conversation history, other Skills' metadata, and the actual 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 explanation?" and "Does this paragraph justify its token cost?"
|
|
|
|
Prefer concise examples over verbose explanations.
|
|
|
|
### Set Appropriate Degrees of Freedom
|
|
|
|
Match the level of specificity to the task's fragility and variability:
|
|
|
|
**High freedom (text-based instructions)**: Use when multiple approaches are valid, decisions depend on context, or heuristics guide the approach.
|
|
|
|
**Medium freedom (pseudocode or scripts with parameters)**: Use when a preferred pattern exists, some variation is acceptable, or configuration affects behavior.
|
|
|
|
**Low freedom (specific scripts, few parameters)**: Use when operations are fragile and error-prone, consistency is critical, or a specific sequence must be followed.
|
|
|
|
Think of Claude as exploring a path: a narrow bridge with cliffs needs specific guardrails (low freedom), while an open field allows many routes (high freedom).
|
|
|
|
### Anatomy of a Skill
|
|
|
|
Every skill consists of a required SKILL.md file and optional bundled resources:
