When publishing an Artifact, Claude Code now parses the document's HTML and gives each block-level element a short b-<hash> id derived from its tag and text, so links can point at a specific block. It runs only on documents carrying the // DOC:anchors:begin marker, and is gated on the flag tengu_cobalt_plinth_quince, whose built-in fallback is true, so it is on unless remote config disables it.
- Ids are written into the source before publish, rewriting existing
id="..."attributes or inserting new ones. - The pass bails out and records telemetry when it cannot locate where the anchors script loads, when an id cannot be placed, when parsing throws, or when the text to hash exceeds 33554432 bytes.
[artifact] doc block ids skipped: too much text to hash
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
