DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Reference / Slash commands

/usage

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.

What it is

Show session cost, plan usage limits, and activity stats. On a Pro, Max, Team, or Enterprise plan, includes a [breakdown of what counts against your plan limits](/docs/en/costs#plan-usage-breakdown). /cost and /stats are aliases

Anthropic's own wording. Read off Commands, captured 2026-08-28.

Presence across releases

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.

Changelog entries naming it

  1. v2.1.223Stats dialog gets a Suspense fallback, a taller frame and a colour fix

    The usage stats dialog is taller, loads more smoothly, and its model chart colours no longer skip.

  2. v2.1.221Session state moves onto a pluggable storage backend

    Session history, resume and usage can now read from a pluggable backend, though files are still used.

  3. v2.1.221Usage stats now count and show cache tokens

    Usage stats now count cache tokens and show a read/write breakdown per model.

Documentation pages

A reference table page is one whose own table defines this name, and it is where the description above came from. A page that mentions it carries the name somewhere in its text and may say nothing about it at all. Every page carrying it.

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.
