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 v2.1.140

User Identity Added to Branch Pattern Context

What

Claude now receives the current user's identity (derived from GITHUB_ACTOR, USER, or USERNAME, or the email username) to correctly resolve the $USER/... personal-branch pattern in rules.

Details
  • A new context line is injected: User identity: \<name>\. The \$USER/...\ pattern in the rules above resolves to \<name>/...\. Branches whose first path segment is a different person's name (\<other-user>/...\) are NOT this user's personal branches.
  • This prevents Claude from treating sibling developers' branches as the user's own.
Evidence

rm_() function (search for "Branches whose first path segment is a different person's name")

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