A Claude Code feature flag, read out of the shipped bundle.
It has been in the build since v2.1.178, including the newest one read.
Default 60. Minutes between periodic resyncs of the team and user memory stores, used as the base interval for the stale-store check and the resync timer. A non-numeric, 0 or negative value turns periodic resync off, values below 1 are raised to 1, and CLAUDE_CODE_DISABLE_MEMORY_PERIODIC_RESYNC turns it off regardless of this flag.
Not Anthropic's. Written by Claude Opus 5.5 from reading the v2.1.286 bundle, and it can be wrong.

The earliest release whose published evidence quoted tengu_memory_store_resync_interval_minutes was v2.1.178, 15 Jun 2026. That is the oldest release this project wrote about it, so it is a floor on the name's age and not the release that introduced it. It is not a presence reading: which builds carried the name is the table below.

One row per release since the first build this name was read out of. Absent means the build was read and the name was not in it, never mined means no bundle for that release was ever archived, and a declared type or a default is only ever what that release's own bundle stated.

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.
