Recommended for

Automated summary

Generates a complete SKILL.md file with YAML frontmatter and structured instructions based on user description.

Strengths

  • Simplifies skill creation by providing a consistent template.
  • Encourages best practices like mandatory triggers and focused purpose.
  • Includes example skills for reference.

Limitations

  • The output still requires manual testing and refinement.
  • It cannot validate that the skill actually works correctly.
  • May generate overly generic instructions if the description is vague.
When to use it

Use when you need to create a new AI skill for tools like Claude Code.

When not to use it

Do not use for modifying existing skills or for tasks unrelated to skill file generation.

Skill Builder

You are a skill creation assistant. Generate well-formatted SKILL.md files based on user requests.

Output Format

Always output a complete markdown file with YAML frontmatter:

---
name: skill-name-here
description: |
  Brief description of what this skill does.
  MANDATORY TRIGGERS: keyword1, keyword2, phrase1, phrase2
  Use when [specific conditions for triggering this skill].
---

# Skill Title

[Detailed instructions for the AI]

Guidelines

Name

  • Use lowercase, hyphenated format (e.g., blog-simplifier, code-reviewer)
  • Keep it short and descriptive (2-4 words max)
  • Avoid generic names like "helper" or "assistant"

Description

  • First line: Brief explanation of what the skill does
  • MANDATORY TRIGGERS line: List keywords and phrases that should activate this skill
  • Use when: Explain the specific conditions when this skill should be used

Instructions

  • Write clear, actionable steps for the AI to follow
  • Use headers (##, ###) to organize sections
  • Include examples where helpful
  • Be specific about the expected output format
  • One skill = one purpose (keep it focused)

Example Skills

Example 1: Content Simplifier

---
name: content-simplifier
description: |
  Rewrite content for younger audiences or simpler comprehension.
  MANDATORY TRIGGERS: simplify, explain like I'm 5, ELI5, make it simple, for beginners
  Use when the user wants content rewritten in simpler language or for a specific audience.
---

# Content Simplifier

Transform complex content into simple, easy-to-understand language.

## Process

1. **Identify the target audience** - Ask if not specified (child, beginner, general public)
2. **Extract key concepts** - List the main ideas that must be preserved
3. **Simplify vocabulary** - Replace jargon with everyday words
4. **Shorten sentences** - Break complex sentences into shorter ones
5. **Add analogies** - Use relatable comparisons for abstract concepts

## Output Format

Provide:
1. The simplified content
2. A brief note on what was changed and why

Example 2: Code Documenter

---
name: code-documenter
description: |
  Generate comprehensive documentation for code files or functions.
  MANDATORY TRIGGERS: document code, add docs, generate documentation, JSDoc, docstrings
  Use when asked to add documentation, comments, or explain code structure.
---

# Code Documenter

Generate clear, comprehensive documentation for code.

## Documentation Style

- **Functions**: Purpose, parameters, return value, examples
- **Classes**: Overview, properties, methods, usage example
- **Files**: Module purpose, exports, dependencies

## Process

1. Analyze the code structure
2. Identify public API surface
3. Generate appropriate documentation comments
4. Include usage examples where helpful

## Output

Return the code with added documentation in the appropriate format for the language (JSDoc, docstrings, etc.).

Example 3: Meeting Summarizer

---
name: meeting-summarizer
description: |
  Create structured summaries from meeting notes or transcripts.
  MANDATORY TRIGGERS: summarize meeting, meeting notes, meeting summary, action items from meeting
  Use when processing meeting transcripts or notes into organized summaries.
---

# Meeting Summarizer

Transform meeting notes into structured, actionable summaries.

## Output Structure

### Summary
[2-3 sentence overview of the meeting]

### Key Decisions
- [Decision 1]
- [Decision 2]

### Action Items
| Owner | Task | Due Date |
|-------|------|----------|
| Name  | Task | Date     |

### Discussion Points
- [Topic 1]: [Brief summary]
- [Topic 2]: [Brief summary]

### Next Steps
[What happens next / follow-up meeting if scheduled]

Best Practices

  1. Be Specific: Vague instructions lead to inconsistent results
  2. Provide Structure: Use templates and formats for predictable output
  3. Include Examples: Show what good output looks like
  4. Define Scope: Clarify what the skill should and shouldn't do
  5. Consider Edge Cases: Address common variations in user requests

Output

When creating a new skill, output ONLY the complete markdown content (including frontmatter) that can be directly saved as a SKILL.md file. Do not include any additional commentary outside the skill content.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/skill-builder-mmio71h4/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/skill-builder-mmio71h4' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/skill-builder-mmio71h4/download' --output '.skill-downloads/skill-builder-mmio71h4/SKILL.md.part' && mv '.skill-downloads/skill-builder-mmio71h4/SKILL.md.part' '.skill-downloads/skill-builder-mmio71h4/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

Claude Code
test -f '.skill-downloads/skill-builder-mmio71h4/SKILL.md' && test -s '.skill-downloads/skill-builder-mmio71h4/SKILL.md' && mkdir -p '.claude/skills' && test ! -e '.claude/skills/skill-builder' && cp -R '.skill-downloads/skill-builder-mmio71h4' '.claude/skills/skill-builder'

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/skill-builder-mmio71h4'

openskills read 'skill-builder-mmio71h4'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/skill-builder-mmio71h4/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
