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

Review - Call skill-reviewer on the target skill
Categorize - Parse issues by severity
Fix - Address critical and major issues
Evaluate - Check minor issues for validity before fixing
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

Critical Issues (MUST fix immediately)

These block skill loading or cause runtime failures:

Missing required frontmatter fields (name, description) — Claude cannot index or trigger the skill
Invalid YAML frontmatter syntax — Parsing fails, skill won't load
Referenced files that don't exist — Runtime errors when Claude follows links
