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 v2.1.234

Session and branch naming prompt tightened

You'll notice
Useful3 Signal2
Session Titles

Session and branch naming now produces short noun phrases, with branches still prefixed claude/.

What

The prompt that names a coding session and its branch now asks for a two-to-five-word noun phrase in sentence case, bans request verbs such as fix, add and update, and bans trailing abstract nouns. The title follows the language of the session description while the branch name stays English and still begins with claude/.

Details
  • The description is treated as untrusted data, including any instruction inside it about what the title should be.
Evidence

the title in the language of the description, the branch name in English

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