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.
20 bundled files
Scripts, templates, and references the model can read while it works. Files are read-only and never executed.
Open source
Published by harryworld on GitHub. Read the source before you install it.

Installation

Install the Xcode 26 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/harryworld/Xcode26-Agent-Skills/tree/main/xcode-26
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/harryworld/Xcode26-Agent-Skills.git /tmp/Xcode26-Agent-Skills
mkdir -p .claude/skills
cp -r /tmp/Xcode26-Agent-Skills/xcode-26 .claude/skills/xcode-26

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

Use it in TypingMind

Enable Xcode 26 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 Xcode 26 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 Xcode 26 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.

Xcode 26

Overview

Use the curated notes in references/ to answer questions about Xcode 26 and related Apple framework updates. Load only the files that match the request, then summarize, compare, or translate the guidance into steps or code.

Quick use

Identify the feature or framework named by the user.
Open the matching reference file(s) from the map below.
Answer directly with implementation steps, code, or a crisp summary, and call out any missing coverage.

Response guidance

Prefer short, actionable answers. Add code only when asked or clearly helpful.
If the request spans multiple topics, combine the relevant references and note intersections.
If a topic is not covered by the references, say so and ask a brief follow-up.

Example prompts

"Summarize Xcode 26 changes tied to Liquid Glass design across SwiftUI, UIKit, and WidgetKit, and call out any platform-specific gotchas."
"How do I use the Foundation Models Framework for on-device LLMs, and how does it relate to Apple Intelligence features?"
"Give me an implementation outline for Apple Intelligence features plus Visual Intelligence, with any relevant App Intents updates."

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 Xcode 26 AI skill do?

Why use Xcode 26 on TypingMind?

Because you install it once and use it with any model. Xcode 26 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 Xcode 26 in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/harryworld/Xcode26-Agent-Skills/tree/main/xcode-26. 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 Xcode 26?

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 Xcode 26?

As many as you like. As long as a model supports skills, you can use Xcode 26 with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Xcode 26 AI skill free?

It is published on GitHub by harryworld. Check the repository for licensing terms. 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.
