At a glance
Walks through creating a new Claude skill from scratch or improving an existing one, asking what it should do, when it should trigger, and in what format.
- Works in 3 steps: Understand intent → Write the SKILL.md → Confirm
- Creating a new skill from scratch
- SKILL.md covers When first invoked, greet the…, Creating a skill, Skill Writing Tips and Editing an Existing Skill
- Runs Python scripts from its folder
What it does
On first use the agent greets the user and offers to create a new skill, edit an existing one, or optimize a description so the skill triggers reliably. For a new skill it asks, one question at a time, what the skill should enable, what phrases or contexts should trigger it, and what output format is expected, then writes a SKILL.md with a name and description to a skills folder, telling the user where it was saved and that it will be available in the next conversation.
Writing tips emphasize that the description is the primary trigger mechanism and should name both what the skill does and specific contexts it applies to, written slightly assertively to avoid under-triggering, with instructions kept under 200 lines, written in imperative form, explaining the reasoning behind a rule rather than just stating it, and including example input and output where helpful. Editing an existing skill follows the same pattern: read the current file, discuss the change, make a targeted edit and save it.
When your agent uses it
- Creating a new skill from scratch
- Editing or improving an existing skill's instructions
- Rewriting a skill's description so it triggers more reliably
Example prompts
- “Help me create a new skill for formatting CSV exports into clean tables.”
- “This skill isn't triggering when I mention invoices. Fix its description.”
- “Edit my existing meeting-notes skill to also extract action items.”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 8cbd7b7. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships 7 files in scripts/ (Python, from the files we listed), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Skill Creator loads about 591 tokens when it runs, and up to ~3.6k if it reads all its reference files. Until then it costs about 37 tokens; SKILL.md has 287 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.
SKILL.md

Skill Creator
You are the Skill Creator. Help users create, edit, and improve skills (reusable instruction sets).
When first invoked, greet the user:
Welcome! I'm ready to help you create, improve, or evaluate a skill. Here's what I can help with:
- Create a new skill from scratch — I'll guide you through defining what it does, writing the instructions, and testing it
- Edit or improve an existing skill — refine its instructions or optimize how reliably it triggers
- Optimize the description so the skill triggers reliably
What are you looking to do? Do you have something specific in mind, or are you starting fresh?
Creating a skill
Step 1: Understand intent
Ask the user (one question at a time, conversational tone):
- What should this skill enable Claude to do?
- When should this skill trigger? (what user phrases/contexts)
- What's the expected output format?
Step 2: Write the SKILL.md
Save to: ~/.claude/skills/<skill-name>/SKILL.md
---
name: skill-name
description: One-line description of what it does and when to use it. Be specific about trigger conditions. Make descriptions slightly "pushy" to avoid under-triggering.
---
Instructions for the skill go here.Step 3: Confirm
Tell the user:
- The skill has been created at
~/.claude/skills/<skill-name>/ - It will be available in the next conversation
- They can edit or improve it anytime
Skill Writing Tips
- Description is critical — this is the primary trigger mechanism. Include BOTH what the skill does AND specific contexts. Example: instead of "Format data" write "Format tabular data into clean markdown tables. Use whenever the user mentions tables, CSV formatting, data organization, or wants to display structured data."
- Keep instructions under 200 lines
- Use imperative form ("Do X", not "You should do X")
- Explain the WHY behind instructions — models work better with reasoning
- Include examples of expected input/output when helpful
Editing an Existing Skill
- Read the existing
~/.claude/skills/<skill-name>/SKILL.md - Discuss with the user what to change
- Make targeted improvements
- Save the updated file

On first use the agent greets the user and offers to create a new skill, edit an existing one, or optimize a description so the skill triggers reliably.md with a name and description to a skills folder, telling the user where it was saved and that it will be available in the next conversation.
When should I use Skill Creator?
Skill Creator fits situations like: creating a new skill from scratch; editing or improving an existing skill's instructions; rewriting a skill's description so it triggers more reliably.
How do I install Skill Creator in Claude Code?
Run `npx skills add pretend1111/claude-desktop-app --skill skill-creator -a claude-code`. Or copy the skill folder (electron/skills/skill-creator in pretend1111/claude-desktop-app) into .claude/skills/skill-creator in your project. Claude Code loads it when a task matches its description.
How do I install Skill Creator in Codex?
Run `npx skills add pretend1111/claude-desktop-app --skill skill-creator -a codex`. Or copy the skill folder (electron/skills/skill-creator in pretend1111/claude-desktop-app) into .agents/skills/skill-creator in your project. Codex loads it when a task matches its description.
Can I use Skill Creator in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add pretend1111/claude-desktop-app --skill skill-creator -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/skill-creator, .gemini/skills/skill-creator, .github/skills/skill-creator and .opencode/skills/skill-creator in your project.
What does Skill Creator need to run?
Going by SKILL.md and its folder, Skill Creator needs Python for the scripts in its folder.
Does Skill Creator access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Skill Creator safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
What licence does Skill Creator use?
Skill Creator is published under the Apache-2.0 licence (from the LICENSE file in the skill folder). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Skill Creator use?
About 591 tokens (SKILL.md is roughly 2.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 3k tokens, read only when the agent opens those files.
What are the alternatives to Skill Creator?
Skills that share tags, products or a category with Skill Creator: Skill Creator (Azure/azqr, 795 stars), Claude Code Skill Developer Guide (diet103/claude-code-infrastructure-showcase, 10k stars), Darwin Skill Optimizer (alchaincyf/darwin-skill, 6.2k stars) and Claude Code Command Development (anthropics/claude-plugins-official, 38k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
