Skill Creator+

Guide for creating and reviewing effective skills.

When to Use

Creating a new skill from scratch
Updating or refactoring an existing skill
Reviewing existing SKILL.md files → See references/skill-review-checklist.md

Core Principles

Principle	Description
Concise is Key	Context window is shared. Only add what Claude doesn't already know.
Degrees of Freedom	Match specificity to task fragility (high/medium/low freedom)
Progressive Disclosure	Split into 3 levels: Metadata → Body → References

Default assumption: Claude is already very smart. Challenge each piece: "Does this justify its token cost?"

Skill Structure

→ references/skill-structure.md for details

skill-name/
├── SKILL.md (required)        # < 150 lines
├── scripts/                   # Executable code
├── references/                # Documentation loaded on demand
└── assets/                    # Output resources (templates, images)

→ See skill-structure.md > What NOT to Include for excluded files.

Creation Process

→ references/creation-process.md for details

Step	Action
1	Understand with concrete examples
2	Plan reusable contents (scripts/references/assets)
3	Initialize: `scripts/init_skill.py <name> --path <dir>`
4	Edit skill and implement resources
5	Package: `scripts/package_skill.py <path>`
6	Iterate based on real usage

SKILL.md Guidelines

Size Target

→ See skill-review-checklist.md > Line Count Target for size guidelines.

Quick rule: < 150 lines is good, > 300 lines must split to references.

Frontmatter

---
name: skill-name
description: "What it does. Use when [trigger conditions]."
---

Description must include: What the skill does AND when to trigger it.

Body

Use imperative/infinitive form
Link to references for details
Keep essential workflow only

Review Checklist

→ references/skill-review-checklist.md

- [ ] SKILL.md under 150 lines?
- [ ] Description has trigger conditions?
- [ ] Details moved to references/?
- [ ] No README.md or auxiliary docs?
