Claude Code & Claude apps

Claude loads skills automatically from its skills directory.

Claude Code

Create a skill folder — personal: ~/.claude/skills/skill-creator/, or per-project: .claude/skills/skill-creator/
Save the skill content as SKILL.md inside that folder.
Claude Code picks it up automatically and invokes it when relevant.

mkdir -p ~/.claude/skills/skill-creator

# Skill Creator

Use this skill to create a new skill from scratch, or to edit, optimize, and measure an existing one.

## What it does
- Scaffolds the `SKILL.md`, scripts, and resource structure for a new skill
- Improves the wording, scope, and workflow of an existing skill
- Runs evals and benchmarks with variance analysis to measure quality
- Tunes the `description` frontmatter so the skill triggers on the right requests and not on the wrong ones

## Why description quality matters
A skill only helps if it loads at the right moment. This skill treats the trigger `description` as a first-class artifact and iterates on it against test prompts.

Description

A meta-skill for building and improving Agent Skills. It scaffolds a new skill from scratch, edits and optimizes an existing one, runs evaluations to test behavior, benchmarks performance with variance analysis, and optimizes a skill's description so it triggers accurately. Use it whenever you are authoring or tuning a skill.
