Don't re-add it from an older description of this file. `redisDocuments()` under + `fileMemory()` only ever sees the two recall points — eve reads the document and injects it whole. +- **Recall is returned as ONE keyed message** (`id: "agentkit-redis-memory"`), like eve's own + `file-memory-document`: eve supersedes a record when the same id comes back with different + content, and omitting an item does **not** delete it — so per-memory ids would accumulate and a + forgotten memory would linger in context. +- **eve requires provider tools be `defineTool()`-branded** (`isBrandedToolEntry` in + `context/memory-tools.js` throws otherwise), and it re-invokes `provider.tools()` from a durable + closure on every execute — so the factory must be pure.

Measured on a live index — captured question **50.9**, + while `User likes cucumber.` (saved deliberately via `save_memory`) was cut from the top 5 + entirely. Asking the agent what it remembers is what degrades what it remembers; `rememberMessages: + false` is the model-curated escape hatch. (This default was flipped off and then back on: off was + the measured-safest, on is the product call. Don't silently re-flip it either way.) `rememberMessages` + is a union: `true` (default, and it means **`"fromUser"`** — the caller's text only) | `"all"` | + `"fromModel"` | `false`. **No function form** — an extractor can't be passed, so `capture: false` + a live `extract` is not expressible + and `defaultExtractMemories` is internal. `"fromModel"`/`"all"` are worse + than `"fromUser"` (the assistant's text is derived from the recalled block, so the agent + re-memorizes its own restatements). `"fromUser"` reads `turn.input` — the turn's own + delivery, kept separate from projected history, so recalled records can't be re-captured; and + every memory's id is `stableHash(text).slice(0,12)`, so identical text collapses onto one key and + capture is idempotent across turns and replays. +- **One store, in its own keyspace — this is the load-bearing decision.** Facts and captured turns + both live at `agentkit:memorySlot::`, with `sessionId`/`source`/`deleted` as **indexed** + fields (plus unindexed `sequence`/`subIndex` for ordering). There is no `ChatHistory` in this path + any more and no option; `read_session` is always contributed and reads the same + records back, sorted `(sequence, sourceRank, subIndex)` where `source` doubles as the intra-turn + ordinal (`userMessage` → `agent` → `agentMessage`). +- **Why its own prefix, and never `agentkit:memory`.** A schema describes an index and an index + covers a keyspace. Upstash Search does **not** match a missing field against `{$eq: …}` and has no + `$ne` — verified live: a doc written without `deleted` is returned by `{userId}` alone and by + nothing that also filters `deleted:{$eq:false}`. So pointing the slot's stricter schema at the + shared keyspace would make every record written by published `@upstash/agentkit-sdk@0.6.0` + silently unreachable. Its own prefix means nothing older is in scope. Costs one of the DB's 10 + indexes; do not "optimise" it back into the shared store. +- **Recall injects `source: "agent"` only.** Captured turns share the store but not the ranking — + that is the structural fix for the measured poisoning (captured question **50.9** vs a + deliberately saved `User likes cucumber.` cut from the top 5). The block ends with a live `count` + of non-fact records pointing at `search_memory`, because black-box testing showed the model does + not use a tool it is merely offered: across 32 conversations it called `read_session` **zero** + times. +- **`forget_memory` redacts, it does not delete.** Text → `""`, `deleted` → `true`; every read but + `read_session` filters tombstones out, and `read_session` renders `[redacted]` so a reader cannot + mistake removal for "never said". Core `AgentMemory.forget` is still a real `DEL` for its other + callers — the provider redacts by calling `add()` with the same id, since `add` writes the whole + document. +- **`"all"`/`"fromModel"` drop `forget_memory`, and this is load-bearing.** Those modes store the + assistant's replies, and the assistant's reply *confirming a deletion quotes the deleted text* — so + erasure writes a fresh copy of what it erased. Measured over 18 black-box conversations on the + rebuilt provider: the curated fact was correctly redacted, and the phrase survived in **three** + other records, all `agentMessage`, all replies about the deletion (a fourth was the tester's own + search query). Agent replies were 18 of 41 records — half the store and the whole leak. A tool that + reports "permanently deleted" while that happens is worse than no tool, so those modes contribute + `save_memory`/`search_memory`/`read_session` only. Don't "restore the missing tool for + consistency" — it was removed because it cannot tell the truth there. +- **Config names carry the phase** (the object is flat, so they have to): `maxRecallCharacters` + (recalled block) vs `maxMemoryCharacters` (one stored memory), `rememberMessages`.

Measured: after the agent reported *"Done — I deleted every stored memory +about your axolotl's tank temperature"*, **5 of 29 records still contained the value**, including the +deliberately-saved canonical fact. In a second configuration the curated fact was deleted and the +verbatim user message holding the same value survived.

Asking the agent what it remembers degrades what it +remembers. + +**The transcript half is unreachable.** Across 32 conversations in which `read_session` existed, was +advertised, had transcripts in Redis and `(session=…)` tags rendered in the recalled block, the model +called it **zero times**.

The other two are reachable on +demand through `search_memory` and `read_session`, which is what keeps a passing remark or a +question from outranking something the model deliberately chose to keep. + +`source` is an **indexed** field, which is what lets automatic recall ask for `source: "agent"` — +the facts the model deliberately saved — and leave captured turns out of that ranking entirely. +Without it a stored *"What do you remember?"* outranks a real fact on the next identical question; +measured on a live index, the captured question scored **50.9** while the saved fact was cut from +the top 5. + +The captured turns are still there: `__search_memory` reaches every record, and +`__read_session` replays one whole session in order — `(sequence, source, subIndex)`, so the +caller's message, the fact the model saved mid-turn, and the reply come back the way they happened. +That is the point of the `session=` tag: a remembered *question* can lead the model to the answer +that followed it. + +
+ +
+Options for redisDocuments() and redisMemory() + +`redisDocuments({ … })` — `redis` (defaults to `Redis.fromEnv()`), `prefix` +(`agentkit:memoryFile`), `ttlSeconds`, `enableTelemetry`. One Redis hash per scope key; the +conditional write eve requires is a Lua `EVAL` compare-and-set. + +`redisMemory({ … })` — `redis`, `prefix` (`agentkit:memorySlot`) / `indexName`, `topK` (5), +`minScore`, `maxRecallCharacters` (4,000 — the recalled block's budget), `maxMemoryCharacters` +(2,048), `rememberMessages` (`true` by default, meaning `"fromUser"` — the caller's own text; `"all"` adds +the assistant's reply, `"fromModel"` captures only that, `false` turns capture off), +`waitForIndexing`, `replayCacheTtlSeconds`, `enableTelemetry`. + +**`"all"` and `"fromModel"` remove `__forget_memory`.** Those modes store the assistant's +replies, and confirming an erasure records the erased text — so deletion cannot be honoured and a +tool reporting success would be lying. Measured over 18 black-box conversations: after one forget, +the fact itself was correctly redacted but the phrase survived in three other records, every one of +them an assistant reply *about* the deletion. `search_memory` and `read_session` still reach +everything; only the claim to remove goes away. + +Its records live in **their own keyspace and index**, not the `agentkit:memory` one the +[memory tools](#memory-tools) share. The slot needs extra indexed fields (`sessionId`, `source`, +`deleted`) and a schema carrying those must not cover a keyspace that already holds records written +without them: Upstash Search does not match a missing field against `{$eq: …}` and has no `$ne`, so +older records would become permanently unreachable. One extra index (a database caps at 10) buys a +store where every record has the same shape. + +The model gets `__save_memory`, `__search_memory` and `__read_session`, plus +`__forget_memory` unless `rememberMessages` stores the assistant's replies (see above). `search_memory` +is the manual counterpart to automatic recall: recall only ever surfaces what is relevant to the +*current* message, so a fuzzy search lets the model go looking for an older fact when the +conversation changes topic. + +**Scope is the tenant boundary.** eve locks it before calling the provider and hands over an opaque +`scope.key` that is used as the storage partition.
