Markdown instructions
A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.
Works with any LLM
AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.
1 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by neutree-ai on GitHub. Read the source before you install it.

Installation

Install the Openapi To Skills AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/neutree-ai/openapi-to-skills/tree/main/skills/openapi-to-skills
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/neutree-ai/openapi-to-skills.git /tmp/openapi-to-skills
mkdir -p .claude/skills
cp -r /tmp/openapi-to-skills/skills/openapi-to-skills .claude/skills/openapi-to-skills

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Openapi To Skills in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Openapi To Skills on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Openapi To Skills is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed
The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.
Switch models mid-chat
Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

openapi-to-skills

Convert an OpenAPI specification into a skill folder with SKILL.md and API references.

Workflow

Determine the spec source and output directory from the request. Input must be OpenAPI 3.x in JSON or YAML; convert Swagger 2.0 first.
Read the relevant sections of references/cli.md to choose options:
- Options for naming, grouping, and filtering.
- Compact Layout for resource pages that consolidate list-call details.
- Overlays to modify the spec before generation.
- Validator to include an offline input checker.
- Case-Insensitive Filesystem Safety for schemas whose names differ only in case.
- Static Assets and External References when preserving hand-authored files or bundling external $refs.
Run the CLI with the selected options:
```
bash
npx openapi-to-skills <spec-path-or-url> -o <output-dir>
```
Use --force when replacing existing generated output is intended: it deletes and recreates the skill directory. Keep hand-authored content in an external --assets directory so it can be reapplied.
Inspect <output-dir>/<skill-name>/SKILL.md and its linked references. Check that the intended operations are present and filters took effect; the file layout depends on the selected layout.

Maintenance

Keep CLI options and behavior documented in references/cli.md. README links to this skill and reference rather than maintaining another options table.

Bundled files

The model reads these on demand while the skill is loaded. They are exposed as readable files and are never executed.

Frequently asked questions

What does the Openapi To Skills AI skill do?

Why use Openapi To Skills on TypingMind?

Because you install it once and use it with any model. Openapi To Skills is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Openapi To Skills in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/neutree-ai/openapi-to-skills/tree/main/skills/openapi-to-skills. TypingMind reads its SKILL.md and bundles its files and installs it as a skill you can enable per chat.

Which AI models can use Openapi To Skills?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Openapi To Skills?

As many as you like. As long as a model supports skills, you can use Openapi To Skills with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Openapi To Skills AI skill free?

Yes. It is published on GitHub by neutree-ai under the Apache-2.0 license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
