A background agent that automatically extracts and saves memories from conversations, running alongside the main conversation without user intervention.
Feature-flagged behind tengu_passport_quail (default: false)
- After each turn, a background agent analyzes recent messages and saves relevant information to memory files
- Uses the
tengu_bramble_lintelflag to control how many turns to accumulate before running (default: 1) - Supports both private (user-only) and team (shared) memory scopes
- Team memory format controlled by
tengu_swinburne_duneflag (alternative two-step format) - Tracks which files the conversation has already written to, skipping extraction if the user manually saved memories
- Coalesces rapid extractions: if one is already running, subsequent requests are stashed for a trailing run
- Sends notification: "Saved N memor(y|ies)" when memories are written
- Memory extraction agent is restricted to only Write, Read, and Edit tools within the memory directory
- System prompt: "A background agent automatically extracts and saves memories from this conversation. If the user asks you to remember or forget something, acknowledge it — the save happens automatically."

tengu_passport_quail Off in both readingsThe flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

A reading is one sample. Claude Code evaluates its flags remotely, so no client sees the targeting rule behind a value and this says nothing about your account.
