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 artemnovichkov on GitHub. Read the source before you install it.

Installation

Install the Sync Xcode 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/artemnovichkov/xcode-skills/tree/main/.claude/skills/sync-xcode-skills
Enable the skill in any chat where you want it available.

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/artemnovichkov/xcode-skills.git /tmp/xcode-skills
mkdir -p .claude/skills
cp -r /tmp/xcode-skills/.claude/skills/sync-xcode-skills .claude/skills/sync-xcode-skills

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

Use it in TypingMind

Enable Sync Xcode 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 Sync Xcode 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 Sync Xcode 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.

Sync Xcode skills

Source of truth is the plugin Xcode exports for the Claude agent, not other copies. Script checks, first found wins:


# 27B52+: dir Xcode passes to its agent as --plugin-dir; no .mcp.json (MCP via --mcp-config)
$(getconf DARWIN_USER_TEMP_DIR)com.apple.dt.IDEIntelligenceAgents/plugins/<build>/xcode-integration/
# older builds
~/Library/Developer/Xcode/CodingAssistant/ExportedPlugins/<build>/claude/   # + .mcp.json
  .claude-plugin/plugin.json   # name: xcode-integration
  skills/<skill>/...

Tmp dirs of older builds get emptied by Xcode — only the current build is reliable there. If unsure where the plugin lives: pgrep -lf "XcodeVersions/.*/claude" and read its --plugin-dir.

Ignore ~/Library/Developer/Xcode/CodingAssistant/codex/skills/__xcode (stale, e.g. still has uikit-app-modernization) and the flattened *.packaged / *.idechatprompttemplate files inside Xcode.app.

Steps

Check (build defaults to xcodebuild -version of the selected Xcode; pass --build for another):
```
bash
python3 .claude/skills/sync-xcode-skills/scripts/check.py [--build 27B52]
```
- Exit 2 = no export for that build. Xcode writes it only when a Claude Agent chat starts (a message sent) in that Xcode. Ask user to open one, then rerun. Don't reconstruct from Xcode.app.
- Output: new/removed skills, added/removed/changed files, export .mcp.json + plugin.json.
Nothing changed → report "repo matches " and stop.
Review: --diff prints unified diffs. Summarize per skill what changed (new sections, removed guidance, new references) — this goes into the commit message/README.
Sync only when user asks: --sync. Copies added/changed, deletes removed, keeps repo's frontmatter key order.
After sync, update by hand:
- README.md skills table: add/remove rows for new/removed skills (one-line summary from SKILL.md description, same style as existing rows). Check plugin-dependent list in Install section (device-interaction, translation, ...) if a new skill uses Xcode MCP tools.
- .mcp.json: match export if script reports NOTE: .mcp.json differs.
- .claude-plugin/marketplace.json: bump metadata.version minor; update plugin description if skills added/removed.
Commit only when asked. Style: Update skills for Xcode 27.2 (27B52), bump to 0.7.0; mention added/removed skills.

Gotchas

Xcode emits SKILL.md frontmatter keys in random order per export. Script compares parsed frontmatter, so order-only differences are not changes. Never cp -R the export over the repo — it creates noisy diffs.
Exported files are read-only (r--r--r--); script rewrites them as 644.
.DS_Store ignored.
Skill text references xcode-integration:<skill> (plugin name in Xcode). Keep verbatim — content is Apple's, unedited.
Compare against older exports to see history between builds: --build 27B48.

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 Sync Xcode Skills AI skill do?

Why use Sync Xcode Skills on TypingMind?

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

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/artemnovichkov/xcode-skills/tree/main/.claude/skills/sync-xcode-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 Sync Xcode 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 Sync Xcode Skills?

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

Is the Sync Xcode Skills AI skill free?

It is published on GitHub by artemnovichkov. 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.
