Source Intelligence

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.

Newer cloud session creation endpoint for review and plan sources

Not switched on

Cloud Sessions not in their notes

Cloud sessions from review or plan sources can use a newer creation endpoint allowing --project grouping.

The newer endpoint and its --project and agent dispatch support need a server flag that falls back to off.

Feature flag
tengu_woven_harbor 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 v2.1.224: not a boolean we can read

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 v2.1.224. It isn't a statement about your account. What a flag value here can and cannot tell you

--project
What

When a cloud session comes from an ultrareview or ultraplan source and the tengu_woven_harbor server flag is on, creation uses a newer endpoint, and only then are grouping sessions under a --project and dispatching to a Kindling agent accepted instead of refused. The flag falls back to off when the server sends no value, so by default the existing refusals still apply.

Evidence
