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 v2.1.248

Comment replies detect when a request was already answered elsewhere

You'll notice
Useful2 Signal2
Artifacts

Comment replies now tell you when someone else already answered that request.

What

When replying to a comment on an artifact fails because the request has already been answered, Claude Code now reads the existing reply out of the error response and returns it, distinguishing an answer you gave yourself from one someone else gave.

Details
  • The two outcomes are reported separately as summon_answered_own and summon_answered_elsewhere.
  • The existing reply is validated against an id pattern before being returned.
  • Every reply telemetry call now carries a resend flag recording whether the attempt was a retry.
Evidence

summon_answered_own

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