What

A comment attached to a spot in an artifact now gets a short snippet of the page content at that spot, so Claude has context even when the comment does not quote any text. Enabled by the tengu_teal_corbel_finial flag, which defaults to on and can be turned off by remote config.

Details
  • The resolver walks the artifact's rendered page to find the element the comment points at, using an id or a tag plus its position among siblings.
  • It then serialises a short version of that element (tag, attributes, truncated text) and attaches it to the comment thread.
  • With the flag off, threads carry only what the comment itself quoted.

tengu_teal_corbel_finial On for this account, and not off by default

The flag server returned on for the one account this site reads, and nothing in this release compiles it off by default. The compiled default is shown below, and says which it is when we cannot read one: a fifth of gates compile in a string or a number rather than on or off, and most published releases have no gate table behind them at all. No client can see what the server returns for your account.

What has happened since
Flag reading moved The flag server now returns on for tengu_teal_corbel_finial, read as this account. A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
