Source Intelligence

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.

Claude Code v2.1.66

/btw Side Question Tip Removed

The tip text "Use /btw to ask a quick side question without interrupting Claude's current work" has been removed. Note: The /btw command itself still exists and functions — only the tip promoting it has been removed.

Evidence

Tip string "Use /btw to ask a quick side question" removed; /btw regex pattern still present (search for "/btw")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
