Creating Skills

Overview

Skills are reference guides for proven techniques, patterns, or tools. Write them to help future Claude instances quickly find and apply effective approaches.

Skills must be discoverable (Claude can find them), scannable (quick to evaluate), and actionable (clear examples).

Core principle: Default assumption is Claude is already very smart. Only add context Claude doesn't already have.

When to Use

Create a skill when:

Technique wasn't intuitively obvious
Pattern applies broadly across projects
You'd reference this again
Others would benefit

Don't create for:

One-off solutions specific to single project
Standard practices well-documented elsewhere
Project conventions (put those in .claude/CLAUDE.md)

Required Structure

Frontmatter (YAML)

---
name: skill-name-with-hyphens
description: Use when [triggers/symptoms] - [what it does and how it helps]
tags: relevant-tags
---

Rules:

Only name and description fields supported (max 1024 chars total)
Name: letters, numbers, hyphens only (max 64 chars). Use gerund form (verb + -ing)
Avoid reserved words: "anthropic", "claude" in names
Description: Third person, starts with "Use when..." (max 1024 chars)
Include BOTH triggering conditions AND what skill does
Match specificity to task complexity (degrees of freedom)

Document Structure

# Skill Name

## Overview

Core principle in 1-2 sentences. What is this?

## When to Use

- Bullet list with symptoms and use cases
- When NOT to use

## Quick Reference

Table or bullets for common operations

## Implementation

Inline code for simple patterns
Link to separate file for heavy reference (100+ lines)

## Common Mistakes

What goes wrong + how to fix

## Real-World Impact (optional)

Concrete results from using this technique

Degrees of Freedom

Match specificity to task complexity:

High freedom: Flexible tasks requiring judgment
- Use broad guidance, principles, examples
- Let Claude adapt approach to context
- Example: "Use when designing APIs - provides REST principles and patterns"
Low freedom: Fragile or critical operations
- Be explicit about exact steps
- Include validation checks
- Example: "Use when deploying to production - follow exact deployment checklist with rollback procedures"

Red flag: If skill tries to constrain Claude too much on creative tasks, reduce specificity. If skill is too vague on critical operations, add explicit steps.

Claude Search Optimization (CSO)

Critical: Future Claude reads the description to decide if skill is relevant. Optimize for discovery.

Description Best Practices

# ❌ BAD - Too vague, doesn't mention when to use
description: For async testing

# ❌ BAD - First person (injected into system prompt)
description: I help you with flaky tests

# ✅ GOOD - Triggers + what it does
description: Use when tests have race conditions or pass/fail inconsistently - replaces arbitrary timeouts with condition polling for reliable async tests

# ✅ GOOD - Technology-specific with explicit trigger
description: Use when using React Router and handling auth redirects - provides patterns for protected routes and auth state management

Keyword Coverage

Use words Claude would search for:

Error messages: "ENOENT", "Cannot read property", "Timeout"
Symptoms: "flaky", "hanging", "race condition", "memory leak"
Synonyms: "cleanup/teardown/afterEach", "timeout/hang/freeze"
Tools: Actual command names, library names, file types

Naming Conventions

Use gerund form (verb + -ing):

✅ creating-skills not skill-creation
✅ testing-with-subagents not subagent-testing
✅ debugging-memory-leaks not memory-leak-debugging
✅ processing-pdfs not pdf-processor
✅ analyzing-spreadsheets not spreadsheet-analysis

Why gerunds work:

Describes the action you're taking
Active and clear
Consistent with Anthropic conventions

Avoid:

❌ Vague names like "Helper" or "Utils"
❌ Passive voice constructions

Code Examples

One excellent example beats many mediocre ones.

Choose Language by Use Case

Testing techniques → TypeScript/JavaScript
System debugging → Shell/Python
Data processing → Python
API calls → TypeScript/JavaScript

Good Example Checklist

Complete and runnable
Well-commented explaining WHY not just what
From real scenario (not contrived)
Shows pattern clearly
Ready to adapt (not generic template)
Shows both BAD (❌) and GOOD (✅) approaches
Includes realistic context/setup code

Example Template

// ✅ GOOD - Clear, complete, ready to adapt
interface RetryOptions {
  maxAttempts: number;
  delayMs: number;
  backoff?: 'linear' | 'exponential';
}

async function retryOperation<T>(operation: () => Promise<T>, options: RetryOptions): Promise<T> {
  const { maxAttempts, delayMs, backoff = 'linear' } = options;

  for (let attempt = 1; attempt <= maxAttempts; attempt++) {
    try {
      return await operation();
    } catch (error) {
      if (attempt === maxAttempts) throw error;

      const delay = backoff === 'exponential' ? delayMs * Math.pow(2, attempt - 1) : delayMs * attempt;

      await new Promise((resolve) => setTimeout(resolve, delay));
    }
  }

  throw new Error('Unreachable');
}

// Usage
const data = await retryOperation(() => fetchUserData(userId), {
  maxAttempts: 3,
  delayMs: 1000,
  backoff: 'exponential',
});

Don't

❌ Implement in 5+ languages (you're good at porting)
❌ Create fill-in-the-blank templates
❌ Write contrived examples
❌ Show only code without comments

File Organization

Self-Contained (Preferred)

typescript-type-safety/
  SKILL.md    # Everything inline

When: All content fits in ~500 words, no heavy reference needed

With Supporting Files

api-integration/
  SKILL.md           # Overview + patterns
  retry-helpers.ts   # Reusable code
  examples/
    auth-example.ts
    pagination-example.ts

When: Reusable tools or multiple complete examples needed

With Heavy Reference

aws-sdk/
  SKILL.md       # Overview + workflows
  s3-api.md      # 600 lines API reference
  lambda-api.md  # 500 lines API reference

When: Reference material > 100 lines

Token Efficiency

Skills load into every conversation. Keep them concise.

Target Limits

SKILL.md: Keep under 500 lines
Getting-started workflows: <150 words
Frequently-loaded skills: <200 words total
Other skills: <500 words
Files > 100 lines: Include table of contents

Challenge each piece of information: "Does Claude really need this explanation?"

Compression Techniques

# ❌ BAD - Verbose (42 words)

Your human partner asks: "How did we handle authentication errors in React Router before?"
You should respond: "I'll search past conversations for React Router authentication patterns."
Then dispatch a subagent with the search query: "React Router authentication error handling 401"

# ✅ GOOD - Concise (20 words)

Partner: "How did we handle auth errors in React Router?"
You: Searching...
[Dispatch subagent → synthesis]

Techniques:

Reference tool --help instead of documenting all flags
Cross-reference other skills instead of repeating content
Show minimal example of pattern
Eliminate redundancy
Use progressive disclosure (reference additional files as needed)
Organize content by domain for focused context

Workflow Recommendations

For multi-step processes, include:

Clear sequential steps: Break complex tasks into numbered operations
Feedback loops: Build in verification/validation steps
Error handling: What to check when things go wrong
Checklists: For processes with many steps or easy-to-miss details

Example structure:

## Workflow

1. **Preparation**
   - Check prerequisites
   - Validate environment

2. **Execution**
   - Step 1: [action + expected result]
   - Step 2: [action + expected result]

3. **Verification**
   - [ ] Check 1 passes
   - [ ] Check 2 passes

4. **Rollback** (if needed)
   - Steps to undo changes

Common Mistakes

Mistake	Why It Fails	Fix
Narrative example	"In session 2025-10-03..."	Focus on reusable pattern
Multi-language dilution	Same example in 5 languages	One excellent example
Code in flowcharts	`step1 [label="import fs"]`	Use markdown code blocks
Generic labels	helper1, helper2, step3	Use semantic names
Missing description triggers	"For testing"	"Use when tests are flaky..."
First-person description	"I help you..."	"Use when... - provides..."
Deeply nested file references	Multiple @ symbols, complex paths	Keep references simple and direct
Windows-style file paths	`C:\path\to\file`	Use forward slashes
Offering too many options	10 different approaches	Focus on one proven approach
Punting error handling	"Claude figures it out"	Include explicit error handling in scripts
Time-sensitive information	"As of 2025..."	Keep content evergreen
Inconsistent terminology	Mixing synonyms randomly	Use consistent terms throughout

Flowchart Usage

Only use flowcharts for:

Non-obvious decision points
Process loops where you might stop too early
"When to use A vs B" decisions

Never use for:

Reference material → Use tables/lists
Code examples → Use markdown blocks
Linear instructions → Use numbered lists

Cross-Referencing Skills

# ✅ GOOD - Name only with clear requirement

**REQUIRED:** Use superpowers:test-driven-development before proceeding

**RECOMMENDED:** See typescript-type-safety for proper type guards

# ❌ BAD - Unclear if required

See skills/testing/test-driven-development

# ❌ BAD - Force-loads file, wastes context

@skills/testing/test-driven-development/SKILL.md

Advanced Practices

Iterative Development

Best approach: Develop skills iteratively with Claude

Start with minimal viable skill
Test with real use cases
Refine based on what works
Remove what doesn't add value

Build Evaluations First

Before extensive documentation:

Create test scenarios
Identify what good looks like
Document proven patterns
Skip theoretical improvements

Utility Scripts

For reliability, provide:

Scripts with explicit error handling (don't defer errors to Claude)
Exit codes for success/failure
Clear error messages
Examples of usage
List required dependencies explicitly

Example:

#!/bin/bash
set -e  # Exit on error

if [ ! -f "config.json" ]; then
  echo "Error: config.json not found" >&2
  exit 1
fi

# Script logic here
echo "Success"
exit 0

Verifiable Intermediate Outputs

For complex operations, create validation checkpoints:

Have Claude produce a structured plan file
Validate the plan with a script
Execute only after validation passes

This catches errors before they compound.
