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.

Reference / Feature flags

tengu_remote_notification_routed

A Claude Code feature flag, read out of the shipped bundle. No mined inventory carries it: everything below comes from what this site has written about it.

What it is

Notifications sent from a remote session now actually reach you instead of being silently discarded.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.223.

Presence across releases

The miner has never read a build containing this name. It is here because a changelog entry of ours names it, which is evidence that it existed and not evidence of which releases carried it. The inventory starts at v2.1.138 and everything older than that was never mined.

Gate readings

No release here has a gate table behind it for this flag. Most published releases have none at all: the readings exist only for versions the pipeline captured flag state on.

Changelog entries naming it

  1. v2.1.223Remote notifications from the session stream are routed into the local notification queue

    Notifications sent from a remote session now actually reach you instead of being silently discarded.

    gate cited by this entry

  2. v2.1.223Remote-stream notifications are namespaced, sanitized and capped

    Notifications sent from remote peers are now trimmed, capped and prefixed so they can't flood your queue.

Documentation pages

None of Anthropic's documentation pages this site has a copy of carries this name.

Read out of the published npm bundle release by release, and out of Anthropic's own documentation as this site captured it. Nothing on this page is a description anybody here wrote about what the feature flag does. All feature flags.
