skill-improver

Skill Improvement Methodology

Iteratively improve a Claude Code skill using the skill-reviewer agent until it meets quality standards.

Prerequisites

Requires the plugin-dev plugin which provides the skill-reviewer agent.

Verify it's enabled: run /plugins — plugin-dev should appear in the list. If missing, install from the Trail of Bits plugin repository.

Core Loop

1. Review - Call skill-reviewer on the target skill
2. Categorize - Parse issues by severity
3. Fix - Address critical and major issues
4. Evaluate - Check minor issues for validity before fixing
5. Repeat - Continue until quality bar is met

When to Use

• Improving a skill with multiple quality issues
• Iterating on a new skill until it meets standards
• Automated fix-review cycles instead of manual editing
• Consistent quality enforcement across skills

When NOT to Use

• One-time review: Use /skill-reviewer directly instead
• Quick single fixes: Edit the file directly
• Non-skill files: Only works on SKILL.md files
• Experimental skills: Manual iteration gives more control during exploration

Issue Categorization

• Missing required frontmatter fields (name, description) — Claude cannot index or trigger the skill
• Invalid YAML frontmatter syntax — P
