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.

Oversized published pages retry without block ids

You'll notice
Useful3 Signal2
Artifacts

A published page that is barely too big is retried without hidden markers instead of failing.

What

When a published artifact page exceeds its byte limit only because of the invisible per-block identifiers added during rendering, it is re-rendered once with those omitted and published again instead of failing.

Details
  • The retry is unconditional inside the publish path and is recorded.
  • The too-large report now also carries how many bytes the block ids accounted for.
Evidence

block_ids_over_cap

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