Editorial interest 81/100 Selection signal · not a rating of the site

A free, open-source macOS utility that asks Claude Code agents to save handoff notes and stop cleanly as a Mac’s battery runs low.

Landing page captured for the 2026-09-28 issue.

For: Claude Code users running agents on macOS
Worth noticing: At 10%, it blocks recognized long commands; the page notes unusual commands or custom scripts can slip through.

Field notes

The hook is described as running on PreToolUse, PostToolUse, and UserPromptSubmit, reading battery state with pmset, and failing open if it cannot read the battery or its input. The page says installation backs up ~/.claude/settings.json and stops without changing it if the file is invalid JSON; hook errors are logged locally.
