anti-sleep

Keep the user's MacBook awake reliably with macOS caffeinate for a set duration or while a process runs. Use for "don't let my Mac sleep", "keep the screen on", "anti-sleep", "caffeinate", overnight work, or long builds. Unlike a normal background job, it survives temporary agent-shell cleanup.

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

Installation

Install the Anti Sleep 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.
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/davidondrej/skills.git /tmp/skills
mkdir -p .claude/skills
cp -r /tmp/skills/skills/ops-and-setup/anti-sleep .claude/skills/anti-sleep

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

Use it in TypingMind

Enable Anti Sleep 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 Anti Sleep 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 Anti Sleep 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.

Anti-Sleep (macOS caffeinate)

Use the bundled launcher from this skill directory. It creates a one-shot user LaunchAgent using only built-in macOS tools.

Required workflow

Never launch caffeinate with raw &, nohup, disown, or launchctl submit. Temporary execution shells can kill their descendants, and launchctl submit can restart a timed job.

Resolve scripts/anti-sleep.sh relative to this SKILL.md; never assume the user's current directory. Run:

Inspect current state:

bash
scripts/anti-sleep.sh status

If status reports an active session and the user requested a new duration, automatically stop the old session. Never ask for confirmation.

bash
scripts/anti-sleep.sh stop

Start the new timer for the requested duration:

bash
scripts/anti-sleep.sh start 10800    # 3 hours

For a specific process, use start-pid. Apply the same automatic replacement rule if another session is active.

bash
scripts/anti-sleep.sh start-pid <PID>

In a separate tool/shell call after the start command has returned, verify:

bash
scripts/anti-sleep.sh verify

Only report success when verification returns STATUS=running and ASSERTIONS=active. Confirm the PID, flags, and wall-clock expiry. If verification fails, run stop and do not claim the Mac is protected.

Assertion flags

The default is -d -i: keep the display on and prevent idle system sleep. Pass explicit flags after the duration or PID when needed:

Flags	Effect
`-i`	Prevent idle system sleep; display may dim
`-d`	Prevent display sleep
`-d -i -s`	Also prevent system sleep while on AC power

Example:

bash
scripts/anti-sleep.sh start 10800 -i

Status and stop

bash
scripts/anti-sleep.sh status
scripts/anti-sleep.sh stop

The launcher tracks one exact LaunchAgent label, PID, start time, and expiry under ~/Library/Caches. It never uses broad pkill.

Fallback

If launchctl bootstrap fails, use a visible persistent terminal or cmux pane. Read the cmux skill before interacting with cmux. If no persistent surface is available, tell the user instead of starting an unreliable background job.

caffeinate cannot keep the keyboard backlight on. That setting is manual: System Settings → Keyboard → “Turn keyboard backlight off after inactivity” → Never.

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 Anti Sleep AI skill do?

Why use Anti Sleep on TypingMind?

Because you install it once and use it with any model. Anti Sleep 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 Anti Sleep in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/davidondrej/skills/tree/main/skills/ops-and-setup/anti-sleep. 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 Anti Sleep?

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 Anti Sleep?

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

Is the Anti Sleep AI skill free?

Yes. It is published on GitHub by davidondrej under the MIT 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.
