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

anti-sleep 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 10d 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.

Anti-Sleep (macOS caffeinate)

When to Use

  • Use when the user wants the Mac to stay awake during a long supervised task.
  • Use when a build, download, or automation run should not be interrupted by sleep.

Keep the Mac awake using the built-in caffeinate command. No install needed.

Quick start — the standard command

caffeinate -d -i -t 7200    # full power: screen stays on + no idle sleep, for 2 hours

Duration is -t <seconds>: 2h = 7200, 7h = 25200, overnight (9h) = 32400.

Aggressiveness levels

Flags Effect
-i prevents idle system sleep only (screen may still dim/lock)
-d prevents display sleep (screen stays on)
-d -i default choice — screen on + system awake
-d -i -s adds -s: prevents sleep even on AC power semantics; -s only works when plugged in
-u -t 1 simulates user activity — wakes the display right now

Default to -d -i -t <seconds> unless the user says otherwise.

Tie to a process instead of a timer

caffeinate -d -i -w <PID>          # stays awake until that process exits (great for builds)
caffeinate -i npm run build       # wraps a command; exits when the command finishes

Run it in a visible terminal (cmux pane)

Prefer running it in the user's own terminal pane so it's visible and easy to Ctrl+C. In cmux (read the cmux skill first if interacting with panes):

cmux send --surface surface:<N> "caffeinate -d -i -t 25200\n"

Otherwise run it as a background Bash task. Never block your own foreground shell with it.

Verify and monitor

pgrep -fl caffeinate                       # is it running? shows exact flags
ps -o etime= -p <PID>                      # how long it's been running
pmset -g assertions | grep -i deny        # confirm sleep assertions are active

Gotcha: caffeinate prints nothing and holds the prompt — it looks "stuck" or like Enter wasn't pressed. It isn't stuck. Verify with pgrep, not by looking at the terminal.

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.
