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

/btw

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

Ask a [side question](/docs/en/interactive-mode#side-questions-with-%2Fbtw) about the current session without adding to the conversation. If you run /btw without a question, Claude Code shows your most recent side question so you can browse earlier answers; if you haven't asked one yet, Claude Code prints a usage line. Before v2.1.212, /btw required a question

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. v2.1.222/btw side questions show a fallback-model notice

    Side questions now show a banner naming the original and fallback model instead of switching silently.

  2. v2.1.222/btw answers can now show a refusal-fallback notice

    If a /btw answer came from a fallback model after a refusal, you now see a warning.

  3. v2.1.222model_refusal_fallback events gain a scope field

    Model fallback events now say whether the swap affects your whole session or just one subagent.

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.
