/loop

slash never mined documented JSON

A Claude Code slash command, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

Skill. Run a prompt repeatedly while the session stays open. Omit the interval and Claude self-paces between iterations. Omit the prompt and Claude runs the built-in maintenance prompt or your loop.md. Example: /loop 5m check if the deploy finished. See Run prompts on a schedule. Alias: /proactive

Anthropic's own wording. Read off Commands, captured 2026-09-28.

The earliest release whose published evidence quoted /loop was v2.1.202, 6 Jul 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table below.

ReleaseDateThe span that was quoted
v2.1.2026 Jul 2026stop the /loop - cancel pending wakeups, schedule nothing
v2.1.24827 Aug 2026Run a prompt or slash command on a recurring interval (e.g. /loop 5m /foo). Omit the interval to let the model self-pace.

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the slash command does. All slash commands.
