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.

Team Workflow Enhancements

What

Improved teammate communication and protocol handling.

Details
  • Operation descriptions now mention "discoverTeams to list available teams to join"
  • Better error messages for missing parameters in teammate operations
  • Clearer separation between message types (message, broadcast, request, response)
Evidence

Operation description updates in SendMessageTool schema, error messages for missing recipient, request_id, etc.

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