Guide for creating effective Claude Code skills. Use when users want to create a new skill, update an existing skill, or need guidance on skill best practices. Triggers on requests like "create a skill", "make a new skill", "help me build a skill", "skill development", or "extend Claude's capabilities".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Skill Creator
Create effective skills that extend Claude's capabilities with specialized knowledge, workflows, and tools.
## Core Principles
### Concise is Key
The context window is shared. Only add what Claude doesn't already know. Challenge each piece: "Does this justify its token cost?"
### Degrees of Freedom
- **High freedom** (text instructions): Multiple valid approaches, context-dependent decisions
- **Medium freedom** (pseudocode/parameterized scripts): Preferred pattern exists, some variation OK
- **Low freedom** (specific scripts): Fragile operations, consistency critical
## Skill Anatomy
```
skill-name/
├── SKILL.md (required)
│ ├── YAML frontmatter (name, description - REQUIRED)
│ └── Markdown instructions
└── Bundled Resources (optional)
├── scripts/ - Executable code (deterministic, reusable)
├── references/ - Documentation loaded into context as needed
└── assets/ - Files used in output (templates, images)
```
### Frontmatter (Critical)
```yaml
---
name: my-skill
description: What it does AND when to use it. This is the ONLY thing Claude sees to decide if the skill triggers. Be comprehensive.

```

How to install
mdr add eltmon/overdeck/claude-skill-creator@sha256:c91a4a6d69d49ecaThe line at the top of this page pins the label git:20260812.45c4d80, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
