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.

Artifact comment replies can be applied as find/replace patches

Not switched on
Useful2 Signal4
Artifacts

Replies to artifact comments can be turned into find/replace edits, with one retry if an edit misses.

A patch applier with retry and failure reasons is built, reachable only via the artifact-comments autoreact feature whose gate is unresolved.

What

A new applier turns a model reply to an artifact comment into a list of find/replace edits against the artifact content, with a single retry when an edit does not land.

Details
  • Walks a list of {find, replace} edits and fails with a reason of "malformed", "not_found", "ambiguous" (the find text occurs twice) or "noop".
  • On the first not_found or ambiguous failure it re-prompts the model once, echoing the offending find text inside fenced DATA and telling it the text "occurs more than once at the point that edit applies (the source as modified by the preceding edits)".
  • Outcomes are reported as edit_patch_apply_failed, edit_patch_retry_fired, patch_retry_echo_refused and stopped_before_patch_retry.
  • Reachable only through the surrounding artifact-comments autoreact feature, whose gate could not be resolved in this build.
Evidence

occurs more than once at the point that edit applies (the source as modified by the preceding edits)

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