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_toasty_breeze

A Claude Code feature flag, read out of the shipped bundle. It has been in the build since v2.1.239, including the newest one read.

What it is

Hitting the 5-hour limit could offer to keep working at reduced priority, but it is off for everyone.

Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.239.

Presence across releases

ReleasesReadingDeclared typeDefault
2.1.245 – 2.1.250 5 releases never mined — —
2.1.239 – 2.1.243 5 releases in the build — unknown

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.

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

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.
