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.

PR review payloads accept an in-page approve stamp binding

Artifacts not in their notes

Review pages can carry an in-page approve button that gets validated when published.

PR review payloads accept an approve action binding, gated behind tengu_walnut_sconce, off by default.

Feature flag
tengu_walnut_sconce Not enough to say

Nothing here resolved what this flag was doing on this version, so nothing here should be read as on or off.

This account: no value returned · anonymous baseline: no value returned · compiled default in v2.1.221: on

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.221. It isn't a statement about your account. What a flag value here can and cannot tell you

tengu_walnut_sconce
What

The pr_review payload schema can carry a stamp describing an in-page approve action, checked against the page's identity when the page is published.

Details
  • stamp is optional and holds a tool name, an input record capped at 8 keys, and a statePath.
  • Validation runs at publish time against the page identity, and failure messages name the fix explicitly.
  • Capabilities-manifest validation now runs in two shapes depending on whether the publish is a republish.
  • Behind tengu_walnut_sconce, fallback false.
Evidence

stamp.input has too many keys (max 8)

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