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 watches can wake on comments, and say why they did not

Artifacts

Watching an artifact could wake on new comments, not just republishes, but it's server-gated off.

Comment-triggered artifact wakes are built but need a remote flag that falls back to false plus remote-session mode.

Feature flag
tengu_scalable_quiche Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

This account: off · anonymous baseline: off · compiled default in v2.1.229: 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 v2.1.229. It isn't a statement about your account. What a flag value here can and cannot tell you

What

In remote sessions, watching a published artifact can now register a wake that fires on new comments as well as republishes, and the tool text was rewritten to match. The whole durable wake path is behind a remote-config flag whose built-in fallback is false, so it is off unless the server turns it on, and it also requires the remote-session mode.

Details
  • Watch results can carry a skip reason, shown as "durable wake subscriptions are not enabled for this session" or "no wake-webhook minter is available (the session's own MCP mount was not found)".
  • The gate is tengu_scalable_quiche, alongside CLAUDE_CODE_REMOTE.
Evidence

This remote session's durable wake rail was skipped as well

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