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 summaries are trimmed, truncated and colour-checked

Elsewhere

Long teammate summaries get trimmed instead of breaking the status line or rejecting the message.

What

Summary and failureReason text from teammates now passes through a trim-and-truncate helper before it reaches the teammate XML tag or the status line.

Details
  • The tag's color attribute is validated against the known colour list rather than escaped and passed through.
  • SendMessage input repair gained a case that truncates an over-long summary instead of rejecting the call.
Evidence

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