# Build Claude Code Skills

Creating valid Claude or Codex skills can be hard when structure, metadata, and disclosure rules are unclear. This skill provides templates, checklists, and examples for building organized skills.

## Install

```bash
npx skillstore add ruvnet/skill-builder

## Capabilities

- Explains required SKILL.md YAML frontmatter fields.
- Shows personal and project skill directory layouts.
- Provides minimal, intermediate, and advanced skill templates.
- Documents progressive disclosure levels and file navigation patterns.
- Includes a validation checklist for skill structure and content.
- Links to Claude skill documentation and examples.

## Use Cases

- Create a Personal Workflow Skill: Build a clear skill for repeated local development, writing, or research tasks.
- Standardize Team Skill Structure: Define shared project skills with consistent metadata, folders, resources, and review checklists.
- Prepare Marketplace Skill Content: Draft skill instructions, examples, and validation steps before packaging a public skill.

## Prompt Templates

### Create a Basic Skill

```
Create a minimal skill for [workflow]. Include the required name and description fields. Add a short quick start and checklist.
```

### Add File Structure

```
Design a project skill for [team workflow]. Show the SKILL.md outline, folder layout, and resource files that should exist.
```

### Improve Existing Skill

```
Review my current skill instructions for [goal]. Suggest frontmatter, disclosure levels, examples, and file references that improve usability.
```

### Build Full Skill Package

```
Create a full skill plan for [domain]. Include templates, scripts, resources, tests, and publishing checks for Claude Code and Codex users.
```

## Limitations

- Does not include executable helper scripts.
- Does not validate generated skills automatically.
- Examples use placeholder commands and URLs that require adaptation.
- Focuses on Claude Code skill structure, not every marketplace rule.

## Best Practices

- Keep SKILL.md concise and move long references into separate files.
- Write descriptions that explain both what the skill does and when to use it.
- Review generated commands and paths before running or publishing a skill.

## Anti Patterns

- Do not bury trigger words in long descriptions.
- Do not place skills inside unsupported nested namespaces.
- Do not publish placeholder commands, URLs, or scripts without review.

- Summary: This skill is a documentation-only tutorial \(a single SKILL.md, 911 lines\) that teaches authors how to build Claude Code skills. All 178 static findings were adjudicated as false positives: the flagged 'backtick execution' patterns are Markdown code fences and inline code spans; the 'path traversal' matches are illustrative relative Markdown links; the 'hidden file' matches all reference ~/.claude/skills/, the documented install location; and the 'hardcoded URLs' are documentation links and example.com placeholders. No executable scripts, no runtime commands, no network calls, and no prompt-injection or data-exfiltration intent were found.
