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 v2.1.251

Extra eligibility check before isolating a teammate in a worktree

Under the hood
Useful2 Signal3
Agents

A new check decides whether a teammate agent is offered its own git worktree.

What

Before falling back to running a teammate agent in its own git worktree, Claude Code now consults an eligibility helper first and only then takes a new fallback path. The existing refusal, that in-process teammates cannot spawn background agents, is unchanged; what is new is a gate deciding whether worktree isolation is offered at all.

Details
  • The helper is the renamed successor of the previous check, and what makes a session eligible is decided inside it rather than at this call site.
Evidence

In-process teammates cannot spawn background agents

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