Skill Reviewer and Enhancer

Review, audit, and enhance existing Claude Code skills to ensure they follow Anthropic best practices and current domain-specific patterns.

Overview

To improve skill quality and ensure adherence to official standards, this skill performs comprehensive analysis of existing skills, identifies structural issues, verifies domain-specific best practices, and automatically applies improvements.

When to Use This Skill

Apply this skill when:

• Reviewing an existing skill for quality and compliance
• Auditing skills before deployment to production
• Updating skills to follow latest Anthropic guidelines
• Ensuring skills use current framework/library patterns
• Identifying missing resources or incomplete implementations
• Enhancing skill descriptions for better discoverability
• Fixing structural or formatting issues
• Modernizing outdated skill instructions

Step 1: Locate and Read the Skill

To begin the review process:

1. Ask user for the skill path or name if not provided
2. Verify the skill directory exists
3. Read the SKILL.md file completely
4. Note the skill's category and purpose

# Find skill
ls skills/[category]/[skill-name]/SKILL.md

# Read skill
Read: skills/[category]/[skill-name]/SKILL.md

Step 2: Analyze Skill Structure

To verify proper skill structure, check for:

Frontmatter Validation

Required Fields:

• name: Must be present, hyphen-case, no angle brackets
• description: Must be present, third-person voice, includes trigger terms, under 1024 characters

Optional Fields:

• allowed-tools: Present for read-only/analysis skills

Validation Script:

python scripts/analyze_skill_structure.py --skill skills/[category]/[skill-name]

Name Convention Check

Verify name follows hyphen-case:

• [OK] Correct: skill-reviewer-and-enhancer, nextjs-fullstack-scaffold
• [WRONG] Incorrect: SkillReviewer, skill_reviewer, skillReviewer

Check for invalid patterns:

• Starts or ends with hyphen
• Contains consecutive hyphens (--)
• Contains uppercase letters
• Contains underscores or other special characters

Description Quality Check

Verify description:

• Voice: Uses third-person ("This skill should be used when...")
• Content: Explains WHAT it does and WHEN to use it
• Trigger Terms: Includes specific keywords users would search for
• Length: Under 1024 characters
• Format: No angle brackets, proper grammar

Step 3: Review Instruction Style

To verify proper instruction format, scan the SKILL.md body for:

Imperative Form Check

Instructions should use imperative/infinitive form:

• [OK] Correct: "To create a form, use the generator script"
• [OK] Correct: "Generate schemas using the Zod validator"
• [WRONG] Incorrect: "You should create forms using the generator"
• [WRONG] Incorrect: "You can generate schemas with Zod"

Use Grep to find second-person usage:

Grep: pattern="\\b[Yy]ou\\b" path="skills/[category]/[skill-name]/SKILL.md" output_mode="content"

Flag any instances for correction.

Section Structure Check

Verify logical organization:

• Overview/Introduction
