  "about": "The memory tool's changes to one target's entries (`entries`, in order) with a size limit (`limit`, characters of the entries joined by \"\\n§\\n\"): one change or a list (`ops`, each `action` add/replace/remove with `content` — or `new_text` — and `old_text`), applied together or not at all; the limit is checked on the result only, and a change that does not grow the entries always goes through. An entry is one fact, at most 400 characters; `old_text` finds an exact entry first, else the one entry containing it. `ok`, the entries after, `message`, `usage`, and `shown` — whether the entries as they were are shown with a refusal, so the model can consolidate.
