caffeinate is a skill for Claude Code from jul-sh/claude-caffeinate. It costs 21 tokens per session (99 once invoked), scanned A, original, MIT.

A session setting that keeps a Mac awake while the coding agent is working, even when its lid is closed.

In plain words
What is it for?

Why use it?

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

caffeinate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

!touch /tmp/claude-caffeinate-enabled

Caffeinate mode is now active for this session. Your Mac will stay awake — even with the lid closed — while Claude is actively working. It will automatically expire 30 minutes after Claude's last tool use, and is cleared when the session ends.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
