tengu_defer_cap_ms
A Claude Code feature flag, read out of the shipped bundle. It was in the build from v2.1.195 and was gone by v2.1.242.
What it is
Backgrounding a task now reads the terminal title and agent from shared stores.
Not Anthropic's. This is the line from the earliest changelog entry here that named it, v2.1.248.
Presence across releases
| Releases | Reading | Declared type | Default |
|---|---|---|---|
| 2.1.245 – 2.1.250 5 releases | never mined | — | — |

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.

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