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.

Teammate names cannot be reserved words or agent-id shaped

Teammates

Teammate names can't be "main", "team-lead", or anything shaped like an agent id.

What

Naming a new teammate now rejects "main" and "team-lead" in any spelling, and rejects any name shaped like an agent id, since such a name already addresses an agent directly. The error asks you to choose another name. Only the plain "main" case was caught before.

Details
  • Validation runs unconditionally when the name is assigned.
Evidence

That teammate name is a reserved recipient ("main" or "team-lead", in any spelling) or has the shape of an agent id, which already addresses an agent directly — choose another teammate name.

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