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 v2.1.227

Auto mode can treat linked git worktrees as already-approved directories

Not switched on
Useful3 Signal3
Permissions Notable

Auto mode could stop asking about sibling git worktrees of the same repo, but it is off.

A worktree fast path for auto-mode directory approvals sits behind a remote flag that falls back to off.

Feature flag
tengu_auto_mode_worktree_fast_path Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.227. It isn't a statement about your account. What a flag value here can and cannot tell you

What

In auto permission mode, when a tool is held for approval only because it touches a directory outside the session, Claude can look up the other working trees linked to the same repository and retry the check with those included. The resolver returns nothing unless tengu_auto_mode_worktree_fast_path is on, and it falls back to off, so behaviour is unchanged in this build.

Evidence

tengu_auto_mode_worktree_fast_path

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