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_bridge_recover_stale_epoch

A Claude Code feature flag, read out of the shipped bundle. It was in the build from v2.1.228 and was gone by v2.1.234.

What it is

Remote sessions gain reconnect and reactivation heartbeats plus stale-connection recovery, all off here.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.228.

Presence across releases

ReleasesReadingDeclared typeDefault
2.1.245 – 2.1.250 5 releases never mined
2.1.234 – 2.1.243 10 releases not in the build
2.1.228 – 2.1.233 5 releases in the build bool:false

A row reading never mined is a release with no archived bundle behind it. Nothing was read out of it, so nothing here says whether the name was in it. A declared type or a default is only ever what that release's own bundle stated.

Two arms, because they disagree: this account is the one account this site reads and anonymous is a baseline with no identity attached. A reading says nothing about your account, and off cannot rule out a rollout both readings sit outside of. What these readings can and cannot show.

Documentation pages

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

Names beside it

Every feature flag in the inventory starting tengu_bridge_recover, up to twelve of them.

tengu_bridge_recovery_patienceRemote Control gives up after 14 reconnect tries and tells you it couldn't reach the server. 2.1.232

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.
