Socket command threading and focus policy for cmux CLI/socket work. Use when adding or changing socket commands, CLI commands, telemetry commands, focus/select/open/close/send-key behavior, or automation that could steal app focus.

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

Installation

Install the Cmux Socket Policy 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/manaflow-ai/cmux/tree/main/skills/cmux-socket-policy
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/manaflow-ai/cmux.git /tmp/cmux
mkdir -p .claude/skills
cp -r /tmp/cmux/skills/cmux-socket-policy .claude/skills/cmux-socket-policy

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

Use it in TypingMind

Enable Cmux Socket Policy 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 Cmux Socket Policy 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 Cmux Socket Policy 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.

cmux Socket Policy

Threading policy

Do not use DispatchQueue.main.sync for high-frequency socket telemetry commands such as report_*, ports_kick, status/progress updates, or log metadata updates.
For telemetry hot paths, parse and validate arguments off-main.
Dedupe and coalesce off-main first.
Schedule minimal UI/model mutation with DispatchQueue.main.async only when needed.
Commands that directly manipulate AppKit/Ghostty UI state are allowed to run on the main actor.
If adding a new socket command, default to off-main handling and require an explicit reason in code comments when main-thread execution is necessary.

Focus policy

Socket/CLI commands must not steal macOS app focus.
Do not activate the app or raise windows unless the command has explicit focus intent.
Only explicit focus-intent commands may mutate in-app focus/selection.
Explicit focus-intent commands include window.focus, workspace.select/next/previous/last, surface.focus, pane.focus/last, browser focus commands, and v1 focus equivalents.
All non-focus commands should preserve the current user focus context while still applying data/model changes.
Open commands (vm/cloud shell, tui, open, new, base, workspace new/open, agent; surface open/new-terminal; cmux open; cmux ssh) focus only when run interactively and stay in the background when run by an agent or script (defaultFocusForUserOpen); --focus opts in, --no-focus opts out. Their socket methods default focus to false, and a pane opened without focus is marked unread.

Remote relay authorization

Every v2 method is a potential cmux ssh relay payload. RemoteRelayCommandPolicy denies by default; allowlisting a method needs the security analysis and policy tests in remote relay authorization.

Detailed references

Read references/threading-and-focus.md when adding a command, changing command execution context, or deciding whether focus changes are allowed.
Read references/remote-relay-authorization.md when adding or changing a v2 method, a remote CLI command, or the relay policy.

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 Cmux Socket Policy AI skill do?

Why use Cmux Socket Policy on TypingMind?

Because you install it once and use it with any model. Cmux Socket Policy 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 Cmux Socket Policy in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/manaflow-ai/cmux/tree/main/skills/cmux-socket-policy. 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 Cmux Socket Policy?

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 Cmux Socket Policy?

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

Is the Cmux Socket Policy AI skill free?

It is published on GitHub by manaflow-ai. 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.
