Every change is signed.

A memory added to the store without going through bettermemory is flagged on the next search.¹

Memory arrives with the prompt.

On Claude Code, the memories that bear on the work are listed for your agent when a session opens and with every prompt, one line each.²

Writes are reviewed.

Temporary notes, secrets and near-duplicates are turned away. For the rest, your agent answers four questions before anything is stored.³

The memory was written into the store directly, without bettermemory, with a log entry forged without the key; two fields of the hit are shown, from 8.0.0 and from the first 9.0 candidate. 8.0 flags a memory planted with no entry, but not one with a forged entry. Signatures are HMAC-SHA256 under a key kept outside the store; the key is symmetric, so a process that can read it can sign (threat model). bench/integrity; the 9 run is commit ad44e75.
The brief is from 9.0.0rc18 on default settings, 2026-11-11, in a throwaway store of four memories; a new session has no conversation yet, so the newest are listed. As a session opens: the project’s standing memories in force and the memories the conversation so far bears on, eight of each at most. On each prompt: up to three matching memories from the project. Each is a pointer, an id with a summary, never a whole memory. The hooks run on Claude Code; other clients reach memory through the tools.
From 9.0.0rc18 on default settings, 2026-11-11, in a throwaway store; the answer’s status and the words it marked are shown. The gates look for passing state, secret-shaped tokens, a model’s control tokens and near-duplicates. The four questions ask how the write relates to what is stored, whether following it would be unsafe, whether it holds a secret, and whether it is a standing instruction. No second model is involved.
bettermemory 8.0 had twenty-seven tools and registered eighteen by default.
