From 0c91af5f3c0ad7cc4135e1ccac0b653fdb788f04 Mon Sep 17 00:00:00 2001 From: "upstash-tag[bot]" <313023939+upstash-tag[bot]@users.noreply.github.com> Date: Wed, 2 Sep 2026 06:43:41 +0000 Subject: [PATCH 01/34] feat(eve): Redis-backed memory integration for eve's native memory slots Adds @upstash/agentkit-eve/memory with two complementary pieces: - redisDocuments(): a MemoryDocumentBackend backed by @upstash/redis, filling eve's documented fileMemory() gap outside Vercel. Optimistic concurrency (MemoryDocumentConflictError) via an atomic Lua eval compare-and-set, since @upstash/redis is REST-only (no WATCH/MULTI). - redisMemory(): a full MemoryProvider wrapping the existing AgentMemory (BM25 ranked/fuzzy recall), giving eve automatic recall/capture at its turn and compaction lifecycle hooks, plus __save_memory/forget_memory tools. Existing tool-based memory (sdk AgentMemory, eve/src/memory.ts, ai-sdk memory, eve-extension recall/save tools) is untouched and stays the only memory path for ai-sdk. Wires an eve-demo example (agent/memory/*.ts) with a mocked-model eval exercising both pieces end to end, added to CI. --- .changeset/eve-redis-memory-slots.md | 47 ++ .github/workflows/ci.yml | 17 + CLAUDE.md | 101 +++- README.md | 4 + examples/eve-demo/README.md | 16 + examples/eve-demo/agent/agent.ts | 40 +- examples/eve-demo/agent/instructions.md | 16 + examples/eve-demo/agent/memory/profile.ts | 21 + examples/eve-demo/agent/memory/recall.ts | 20 + examples/eve-demo/evals/evals.config.ts | 3 + examples/eve-demo/evals/memory.eval.ts | 43 ++ packages/eve/README.md | 74 +++ packages/eve/package.json | 6 +- packages/eve/src/eve-memory.test.ts | 487 ++++++++++++++++ packages/eve/src/eve-memory.ts | 668 ++++++++++++++++++++++ packages/eve/src/index.ts | 4 + packages/eve/tsup.config.ts | 1 + 17 files changed, 1561 insertions(+), 7 deletions(-) create mode 100644 .changeset/eve-redis-memory-slots.md create mode 100644 examples/eve-demo/agent/memory/profile.ts create mode 100644 examples/eve-demo/agent/memory/recall.ts create mode 100644 examples/eve-demo/evals/evals.config.ts create mode 100644 examples/eve-demo/evals/memory.eval.ts create mode 100644 packages/eve/src/eve-memory.test.ts create mode 100644 packages/eve/src/eve-memory.ts diff --git a/.changeset/eve-redis-memory-slots.md b/.changeset/eve-redis-memory-slots.md new file mode 100644 index 0000000..4831c00 --- /dev/null +++ b/.changeset/eve-redis-memory-slots.md @@ -0,0 +1,47 @@ +--- +"@upstash/agentkit-eve": minor +--- + +feat(eve): add `@upstash/agentkit-eve/memory` — Upstash Redis behind eve's native memory slots + +A new subpath export with **two** integrations for eve's [memory](https://eve.dev/docs/memory) +feature (`agent/memory/.ts`), because eve exposes two genuinely different seams: + +- **`redisDocuments()`** — a `MemoryDocumentBackend` for eve's built-in `fileMemory()` provider, a + drop-in replacement for its Vercel Blob storage: `fileMemory({ backend: redisDocuments() })`.

This is the + * narrow, faithful fix for eve's documented gap: with no `backend`, `fileMemory()` resolves to + * in-memory storage under `eve dev`, to Vercel Blob on Vercel, and **errors everywhere else**. + * Pick `redisMemory()` when the memory should grow past what fits in a 4,000-character preamble and + * should be *retrieved* rather than replayed wholesale, or when you don't want to rely on the model + * remembering to call `save_memory`. + * + * They compose: nothing stops an agent from declaring both slots (see `examples/eve-demo`). + * + * Neither replaces {@link defineMemoryRecallTool}/{@link defineMemorySaveTool} from the package + * root. Those are plain eve tools you drop into `agent/tools/*.ts` — they work on any eve version, + * need no memory slot, and are the right thing when you want memory to be purely model-driven. + * + * ## Optimistic concurrency without WATCH/MULTI (verified, not assumed) + * + * `MemoryDocumentBackend.write()` is a conditional replace: it must throw eve's + * `MemoryDocumentConflictError` when the caller's `expectedVersion` no longer matches the stored + * one (`fileMemory()` catches it, re-reads, and retries up to 8 times). `@upstash/redis` speaks the + * **REST** API, which is stateless and therefore has no `WATCH`/`MULTI` — so the compare and the + * swap have to happen inside a single server-side command. + * + * That command is `EVAL`. **Verified live against an Upstash Redis instance** (2026-09, an + * `upstash start-redis` database on the current REST API), not assumed: + * - `EVAL` is accepted over the REST API and through `@upstash/redis`'s `redis.eval(script, keys, + * args)`, including with auto-pipelining enabled (the default); + * - a Lua table return (`{0, currentVersion}` / `{1, newVersion}`) round-trips as a JSON array, so + * the script can report *why* it refused and what the current version is; + * - `HGET`/`HSET`/`EXPIRE` inside the script behave normally, and `SCRIPT LOAD` works too. + * + * The script ({@link CAS_SCRIPT}) is sent with every write rather than cached as a SHA + `EVALSHA`: + * it is ~300 bytes, writes are rare (one per `save_memory`/`remove_memory` call), and `EVALSHA` + * would need a `NOSCRIPT` fallback path for no measurable gain. + * + * ## Storage layout + * + * `redisDocuments()` stores one Redis **hash** per eve scope key at + * `agentkit:memoryFile:` with two fields, `content` and `version`. A hash (rather than a + * JSON string) keeps the Lua script trivial: it compares one field and writes two. + * + * The stored `content` carries a short {@link CONTENT_MARKER} prefix, stripped on read. This is not + * decoration: `@upstash/redis` **auto-deserializes** replies, so a document whose text happens to + * be valid JSON (`123`, `{"a":1}`) comes back as a `number`/`object` instead of the exact string + * that was written — measured, not theorized. The marker makes every stored value un-parseable as + * JSON, which guarantees `read()` returns the document byte-for-byte as `write()` received it. + * eve's own document format starts with an HTML comment today, but the backend contract is "any + * UTF-8 string" and a corrupted round-trip would surface as an opaque + * "Memory backend returned an invalid versioned memory document." much later. + * + * `redisMemory()` stores nothing new: it is {@link AgentMemory} (one JSON doc per memory at + * `agentkit:memory::`, one shared Redis Search index), keyed by eve's scope key. That + * means the 10-index cap on an Upstash database is not affected by adding memory slots, and the + * store is the same one `defineMemorySaveTool` writes to. + * + * ## Indexing lag on the capture path + * + * Upstash Redis Search indexes asynchronously, and the lag after a bare `json.set` is much longer + * than "the next turn": in an end-to-end eve run, a fact captured at `turn.completed` was still + * invisible to recall eight turns and ten seconds later, and only appeared minutes afterwards. + * Automatic capture would therefore look broken exactly when it matters. So capture ends with + * `waitIndexing()` (see `waitForIndexing`) — free, because eve runs capture *after* the response + * is delivered — and recall stays wait-free on the hot path. + * + * ## eve version + * + * This entry point imports `eve/memory` and `eve/memory/file`, which eve added in **0.45.1** and + * **0.45.2** respectively — newer than the package's `>=0.32.0` peer floor, which is set by the + * (much older) root and `./sandbox` entry points. Importing `@upstash/agentkit-eve/memory` on an + * older eve fails at module load with an unresolved-subpath error.

That is a read overtaking replication. Upstash serves read-your-writes with an `upstash-sync-token` header, and `@upstash/redis@1.38.0` sends it one request late: `HttpClient.request()` builds `requestHeaders` from `this.headers` and only afterwards copies `this.upstashSyncToken` into `this.headers`, so every request carries the token from one response ago. The read straight after a write therefore travels with a token that pre-dates the write and a replica is free to answer from behind. It is a race — the replica is normally current within the round trip — which is why ~15 other write-then-read pairs in the same file passed and a single-region dev database never reproduced it. A false "absent" is the one answer that actually costs something: eve's `fileMemory()` reacts by starting a fresh document and writing it with `expectedVersion: null`, which conflicts and retries. So the backend now keeps a bounded FIFO set of scope keys it has written and confirms an "absent" answer for one of them with up to two re-reads — any extra request flushes the correct sync token, so the retry is the request that carries it. Keys this instance never wrote still resolve to `null` on the first read, so the common "no document yet" path is unchanged at one round trip. Reproduced deterministically with a scripted lagging client rather than waiting on the race: the two new offline tests fail against the previous `read()` with the exact CI message and pass with this one. The `ttlSeconds` assertion now polls, since `redis.ttl` is a raw metadata read that `read()` cannot cover. CLAUDE.md records the sync-token behaviour under Testing — it is a latent flake for every live-Redis suite in the repo, not just this one. No design decision, export or file from the original change is altered.

Nothing that checks whether the recall methods are called and things are saved to redis." Fair. The live suite only ever drove `turn.started`/`turn.completed`, and it asserted on the rendered block — so a provider that recalled from an in-process cache, queried the wrong index, or never wired the compaction hooks would still have passed, and nothing ever read a memory document back out of Redis. Recall/capture invocation — a new offline suite, deterministic (no network, no BM25, no indexing lag). It spies `AgentMemory.prototype.recall`/`add`, and where it doesn't spy it runs the real AgentMemory over a scripted client that records every index query and json.set. It pins down: - recall["turn.started"] AND recall["compaction.completed"] each delegate to AgentMemory.recall exactly once, with the sanitized locked scope, the configured topK/minScore, and the caller's own words as the query; - the call reaches Redis as `search.index({name:"agentkit_memory"})` + `query({filter:{userId:{$eq},text:{$smart}},limit})` — tenant-scoped and fuzzy, on the shared index rather than a slot-private one; - the rows the index returns are what the model sees (": "); - a replayed operationId re-queries the index ZERO times (the cache has to short-circuit the search, not just the formatting), while a fresh operationId queries again and sees new state; - a text query that matches nothing falls back to a filter-only query; - capture["turn.completed"] AND capture["compaction.requested"] each add every user message (never the assistant's) through AgentMemory.add with a content-hash id, then wait for indexing; - the write lands as one json.set per memory under the scope's prefix. Redis persistence — three new live tests. One asserts real Redis state after a capture: `keys` returns exactly the content-addressed keys (derived in the test from stableHash, not hardcoded) and `json.get` equals {text,userId,createdAt}. One takes the id and text back OUT of Redis and asserts the recalled block contains that exact ": ", closing capture -> Redis -> recall. One does the same round trip through compaction.requested -> compaction.completed. Isolated scopes now go through a `newScope()` helper that registers them for cleanup; two were leaking keys. eve-demo's eval goes 7 -> 9 gates: the captured fact carries a per-run nonce, `Redis.fromEnv()` inside the eval scans agentkit:memory:* and asserts the stored document contains it, and the recalled block must contain it too — so persistence is proven through eve's own runtime and cannot pass on a document an earlier run left behind. All of it mutation-checked: dropping the two compaction hooks and the memory.add call turns 10 tests red; `capture: false` on the demo slot turns 3 eval gates red, including the new persistence one.

Measured against a live index — the captured question scored 50.9, while "User likes cucumber." (saved deliberately through save_memory) was cut from the top 5 entirely. Asking the agent what it remembers is what degraded what it remembered. `capture: boolean` and `extract` collapse into one `autoCapture` union — false | true/"fromUser" | "fromModel" | "all" | an extractor fn — which also removes the illegal state `capture: false` alongside an `extract` that silently never ran. "fromModel"/"all" are worse than "fromUser" (the assistant's text is derived from the recalled block, so the agent re-memorizes its own restatements) and their JSDoc says so. The remaining renames make each flat field say which phase it belongs to: maxCharacters -> maxRecallCharacters (the recalled block) maxEntryCharacters -> maxMemoryCharacters (one stored memory) query -> buildRecallQuery tools -> memoryTools defaultExtract -> defaultExtractMemories New `conversations` option (default false) is small-to-big retrieval: it stores each turn's transcript through core ChatHistory keyed by the eve session id, stamps that id on every memory captured or saved in the turn, tags recalled memories `conversation=`, and contributes a `read_conversation` tool. Memories stay ranked individually — what BM25 is good at — and the model expands a match into the surrounding exchange on demand, so a remembered question can lead to the answer that followed it without transcripts being injected into every prompt. The recalled block is filtered out before storing, or recall output would round-trip into the transcript recall later expands. The pointer is not a snapshot: the transcript keeps growing after the memory is written. `save_memory` now waits for indexing like capture already did. Upstash Search indexes asynchronously with lag in the tens of seconds, so without it a model that saves a fact and is asked about it next turn recalls nothing — which reads as the save being lost. `waitForIndexing: false` opts out.

Rather than turning autoCapture on in the demo — the setting that makes an agent look amnesiac in interactive use — the mock model gains a second trigger so each slot is exercised through its own save tool: "REMEMBER: " -> profile__save_memory (eve's file memory, our Redis storage) "NOTE: " -> recall__save_memory (our MemoryProvider) Recall itself is still asserted as automatic: eve runs the provider's turn.started handler and injects the ranked block before the model sees anything, and the mock echoes what arrived in its prompt. Automatic capture keeps its own coverage in packages/eve/src/eve-memory.test.ts. The demo slot also turns on `conversations`, so `recall__read_conversation` is wired up in a real agent. Eval passes 10/10 gates against real Redis.

In a workspace, `next` and `@upstash/agentkit-eve` under examples/eve-demo/node_modules are symlinks into the repo-root .pnpm store, which that root excludes — so the build failed with "We couldn't find the Next.js package (next/package.json) from the project directory". Both `outputFileTracingRoot` and `turbopack.root` now point at the monorepo root; Next requires them to be equal. With this, `vercel build` + `vercel deploy --prebuilt` from the repo root works without publishing any workspace package. It needs the project linked at the root with rootDirectory=examples/eve-demo, and `vercel pull` re-nulls `framework` and `rootDirectory` in .vercel/project.json, so re-apply them after a pull. Also gitignore `.vercel`, which was untracked at the repo root — `vercel pull` writes project secrets into it.

They now use `ContextMessage = MemoryOperationContext["messages"][number]` — the AI SDK `ModelMessage`, derived from eve's own context type rather than imported from `ai`, which is only a devDependency here. `messageText` narrows the content parts through their real discriminated union instead of a hand-rolled predicate, and `textsWithRole` takes `ContextMessage["role"]` rather than `string`, so a typo like "assistent" is now a compile error. The provider tool map is likewise built as `Record`, so it is checked as it is assembled and the `as unknown as MemoryToolSet` on the return is gone. The per-tool `as Parameters[0]` casts stay: eve types a provider tool's `execute` input as `never`, which no concrete input satisfies. No `unknown` left in provider.ts. The one in documents.ts is deliberate and now says so — `@upstash/redis` auto-deserializes replies, so an `HMGET` field really can come back as a number or object, and the `typeof` guards are the recovery.

One job, finished, unchanged all week. `redisMemory()` was a good implementation of a commodity. Two things decided it: - Its API moved three times before release — capture default, six renames, conversations. That churn is what this repo's naming history is a museum of, and nothing was published yet, so holding costs nothing while shipping locks it. - Once autoCapture had to default off (captured utterances outrank curated facts in a shared BM25 ranking — measured: a captured "What do you remember?" scored 50.9 while a deliberately saved fact was cut from the top 5), its differentiator narrowed to "the store can exceed eve's 64 KiB / 4,000-char ceiling". Real, but much narrower than the docs claimed, and everything else it offered is already covered by defineMemoryRecallTool/defineMemorySaveTool, ai-sdk createMemoryTools and the extension's recall_memory/save_memory. Also reverts the `conversationId` field on core AgentMemory: it existed only to point a memory at a ChatHistory transcript for the provider's `conversations` feature, and shipping an optional public field with no consumer is the same unsettled-surface problem. The provider and its ~25 tests stay in git history; CLAUDE.md records where to find them and the one case worth resurrecting them for.

The backend alone only solves storage. `fileMemory()` recall replays one document whole, so a slot backed by `redisDocuments()` cannot retrieve by relevance at all; searchable memory was only reachable through the standalone tools, which the model has to remember to call. Automatic ranked recall at `turn.started` is the thing this package is for, and it lived here. Narrowings: - **`memoryTools` is gone.** `save_memory`/`forget_memory` are always contributed — a memory slot with no way to save or forget is a strange thing to declare, and the flag only existed because the tools and the transcript reader were once gated together. - **`autoCapture` no longer takes a function.** The union is `true`/"fromUser" | "fromModel" | "all" | false, and `defaultExtractMemories` is now internal. Custom extraction was the least-used and most open-ended part of the surface; a caller who wants distilled facts can call `save_memory` with them. `autoCapture` now defaults to `true`. The measured hazard is unchanged and stays documented on the option, in the changeset and in CLAUDE.md: captured utterances and curated facts share one BM25 ranking, and a stored "What do you remember?" scored 50.9 against the next one while a deliberately saved fact fell out of the top 5. `autoCapture: false` is the model-curated escape hatch. 141 tests, both demo builds, and the demo's mocked-model eval (10/10 gates against real Redis) all pass.

The user-facing README did not mention them at all, so nothing said what happens at each point or why the pairing is what it is. Adds a lifecycle table covering both integrations, plus the two consequences that are not guessable: capture runs after the response is delivered, which is what makes blocking on waitIndexing() free; and recall runs a second time at compaction.completed so memory is re-injected against the new checkpoint instead of being folded into the summary. Also records that recall is cached per operationId because eve treats that id as an idempotency key and rejects a differing replay. Also documents what a recalled block can contain, including the gap: three sources land in one list — save_memory facts, the caller's turn text, the assistant's reply — and nothing distinguishes them. A record is {text, userId, createdAt, conversationId?} with no source field, and both write paths share the stableHash(text) id, so identical text collapses onto one record whichever way it arrived. `autoCapture: false` is the only way today to guarantee every memory was deliberately saved. The conversation= tag is present only for records written while `conversations` was enabled; turning it on later does not backfill. README carries the full version, the memory/index.ts barrel a condensed one, formatRecall's JSDoc the block shape, and CLAUDE.md both plus the note that adding a `source` field would need an indexed schema change (unlike conversationId, which rides along unindexed).

This does not collapse the alice/bob dropdown, because `demoUserAuth` runs before `localDev()` in the channel's auth walk, so the UI's `x-user-id` header still supplies the principal and each user keeps a separate partition. The eve TUI sends no header and lands on the shared `local-dev` principal, which is what it did before. The comment on each slot now says outright that the header is demo-only and is not a tenant boundary — anyone can set it — since these two files are what a reader copies. Changing the scope changes the partition key, so memories written under the old scope are stranded rather than migrated. Eval still passes 10/10 gates.

It replaces the single-purpose `conversationId` field: one extensible passthrough instead of a growing list of special cases. Like `createdAt` it is stored but left out of the search schema, so it costs no index change and no re-index; the price is that it cannot be filtered or searched on, which the JSDoc now says outright. `redisMemory()` uses it to close the provenance gap. Every write stamps a source: "agent" -> the model chose to remember it, via save_memory "userMessage" -> captured from the caller's turn text "agentMessage" -> captured from the assistant's reply and recall renders it per line, so the block now reads a1b2c3d4e5f6: The user prefers dark mode (you saved this, conversation=wrun_01ABC) 9f8e7d6c5b4a: I ride a Brompton (the user said this) with the preamble telling the model that a saved fact was chosen deliberately while a captured turn may be off-hand. All three used to land in one ranked list with nothing to tell them apart, which was documented as a limitation two commits ago; this is that limitation fixed. Extractors now return {text, source} rather than bare strings, so "all" tags each half of a turn correctly instead of guessing from position. Records with no metadata — written before this, or by the standalone memory tools that share the same store — get no note rather than a guessed one, and there is a test pinning that.

Automatic recall only ever surfaces what matches the *current* message, so until now the model had no way to look something up after the conversation changed topic — it could save and forget, but not search. Fuzzy match over the memory text, `userId` pinned to the locked scope like every other tool, capped at 25 results. Renames the two options that decide what a slot does, from what the code does to what the caller gets: autoCapture -> rememberMessages conversations -> rememberSessions "Session" is eve's own noun, not a synonym invented here: its docs use it 1011 times against 84 for "conversation", the id being stored is literally `context.session.id`, and core ChatHistory's field is already `sessionId`. `@supermemory/eve` independently named its equivalent tool `read_session`. So the rename runs all the way through — `read_conversation` -> `read_session`, the metadata field `conversationId` -> `sessionId`, and the recalled-block tag `conversation=` -> `session=`. Both options moved directly below `redis`, since everything else is tuning, and both now default to on. `true` for `rememberMessages` means "all" — both halves of a settled turn rather than the caller's text alone. The measured ranking hazard is unchanged and still documented on the option: captured turns and saved facts share one BM25 ranking, a captured question scored 50.9 against the next one, and capturing the assistant's reply compounds it because the reply is derived from the recalled block. `search_memory` and the per-record `source` label are what make that liveable — the model can see which memories it chose and go looking when ranking buries one. Removes `buildRecallQuery`: the recall query is always the turn's user text. Every optional config field now carries a JSDoc `@default` tag. 143 tests, both demo builds and the demo eval (10/10 gates against real Redis) pass.

Metadata is stored top-level, because Redis Search indexes JSON by path and a nested object would not be filterable. Omit `metadataSchema` and the store is exactly what it was — same two indexed fields, same index, same keyspace, no re-index. That is what keeps this additive for `ai-sdk`, `eve/memory-tools` and the extension runtime, which all share `agentkit:memory`. An extended store must use its own `prefix`, and the reason is verified rather than stylistic: a document written without a `deleted` field is returned by `{userId: {$eq: …}}` and by nothing that also filters `deleted: {$eq: false}`, and Upstash Search rejects `$ne` outright. Extending the shared schema in place would have made every record written by published 0.6.0 permanently unreachable — still in Redis, never returned, no error. Breaking: `recall()` no longer falls back to "everything for the user" when a query matches nothing; it returns nothing. The fallback made a miss indistinguishable from a hit, so a model reported unrelated memories as results — black-box testing caught an agent claiming "I do not see that in the stored entries" from an unfiltered dump it took for a filtered one. Omitting the query is still how you ask for the whole set, and every memory-tool caller is affected.

Black-box testing against examples/eve-demo showed what that cost: - deletion could not be honest. forget_memory deletes one memory key and nothing ever deleted from the transcript, so 5 of 29 records still contained a value the agent reported it had permanently erased. - captured turns buried curated facts. Recall queries with the caller's current message, so a stored "What do you remember?" scored 50.9 against the next identical question while "User likes cucumber." was cut from the top 5. - the transcript half was unreachable. Across 32 conversations where read_session existed, was advertised and had transcripts in Redis, the model called it zero times — once answering "MY SIDE NOT AVAILABLE" with the answer one tool call away. Everything now lives in one keyspace of the slot's own, `agentkit:memorySlot`, with sessionId/source/deleted indexed and sequence/subIndex along for ordering. Its own keyspace is required, not tidiness: a schema with extra fields must not cover the shared `agentkit:memory` prefix, whose existing records lack them and would become unreachable. - recall injects source:"agent" only, so captured turns share the store but not the ranking. The block ends with a live count pointing at search_memory, because the model does not use a tool it is merely offered. - forget_memory redacts rather than deletes: text erased, deleted set, invisible to every read except read_session, which renders [redacted] so a reader cannot mistake removal for "never said". - read_session replays a session sorted (sequence, sourceRank, subIndex), where source doubles as the intra-turn ordinal: the caller speaks, the model saves, it answers. Removes rememberSessions (read_session is always contributed) and the compaction.requested capture — messages are stored as they happen, so the summarizer takes nothing with it, and it was the only context where sequence could be null.

That would have made every record written by +published `@upstash/agentkit-sdk@0.6.0` silently unreachable.

Facts and captured messages go to +`AgentMemory` (`agentkit:memory:*`); turn transcripts go to `ChatHistory` (`agentkit:chat:*`). +Nothing reconciles them, and three failures follow directly from that. + +**Deletion does not delete.** `forget_memory` calls `memory.forget()`, which is one `redis.del` on a +memory key. Nothing in the provider ever calls `deleteChat`. So a value the caller asked to erase +survives in the transcript no matter what — and, when message capture is on, in every other record +that happened to quote it. 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. Same root cause, opposite survivor. + +**Captured messages bury curated facts.** Recall queries with the caller's current message, so a +stored *"What do you remember?"* scores near-perfectly against the next *"What do you remember?"*. +Measured on a live index: captured question **50.9**, while `User likes cucumber.` — saved +deliberately — was cut from the top 5 entirely. 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**. Asked point-blank to reconstruct an earlier exchange it answered +*"MY SIDE NOT AVAILABLE"* with the answer one tool call away. + +One store fixes the first, an indexed `source` fixes the second, and folding transcripts into that +store makes the third cheap enough to keep. + +## The record + +One document per stored item, at `agentkit:memory::`. + +```ts +{ + text: string; // redacted to "" when deleted + userId: string; // eve's scope key — the tenant boundary + sessionId: string; // the eve session this came from + source: "agent" | "userMessage" | "agentMessage"; + deleted: boolean; + sequence: number; // turn.sequence within the session + subIndex: number; // position within the turn, per source + createdAt: number; +} +``` + +`id = stableHash(sessionId + sequence + subIndex + text).slice(0, 12)`. + +Deterministic, so a durable replay of the same turn writes the same key — the property that makes +capture idempotent today, preserved.

Neither needs to know how many records the other wrote. + +## Lifecycle + +| eve phase | what happens | +| --- | --- | +| `turn.started` | recall — one `$smart` query filtered to `source:agent, deleted:false`, plus a `count` of this scope's non-agent records | +| `turn.completed` | write this turn's messages, per `rememberMessages` | +| `compaction.requested` | **nothing — hook dropped** | +| `compaction.completed` | recall again, against the new checkpoint | + +`compaction.requested` existed to grab facts before history was summarized away.

It exists because of a measured +behaviour: the model does not search unless given a concrete reason to. + +## Deletion + +`forget_memory` becomes an update, never a delete: + +``` +text -> "" +deleted -> true +``` + +Every query except `read_session` filters `deleted:false`, so a redacted record can never be recalled +or searched again. `read_session` keeps it in sequence and renders it as a tombstone, so the model +sees that something was removed rather than an unexplained gap it might try to re-derive or re-ask. + +The tombstone is permanent; there is no hard delete. + +**The `deleted:false` clause belongs in core `AgentMemory.recall`, not in the provider.** The +`agentkit:memory` index is shared with `defineMemorySaveTool`, ai-sdk `createMemoryTools` and the +extension's `recall_memory`.

The curated fact was correctly redacted. But the phrase the caller asked to erase survived in three other records, and every one was an `agentMessage` — the assistant's own replies *about* the deletion. Confirming an erasure records the erased text, so deleting writes a fresh copy of what it deleted, and deleting more would write more. A fourth survivor was the caller's own search query. Two changes follow from that. `rememberMessages` now defaults to `true` meaning "fromUser" rather than "all". In the same run the assistant's replies were 18 of 41 stored records — half the store, and the entire source of the leak. They are also derived from the recalled block, so capturing them re-memorizes the agent's own restatements. `"all"` and `"fromModel"` no longer contribute `forget_memory` at all. Those modes store replies, so deletion cannot be honoured, and a tool answering "permanently deleted every stored item that mentioned it" is worse than no tool — a caller reasonably believes it. `search_memory` and `read_session` still reach everything; only the claim to remove goes away. Gating covers "fromModel" as well as "all" because it has the identical property. The reasoning lives on the `rememberMessages` JSDoc, in the README, and in CLAUDE.md with a note not to restore the tool for consistency: it was removed because it cannot tell the truth there.

The first three are the feature: metadata round-trips through add and recall with a non-string field intact, a ranked recall narrows by a metadata field, and list()/count() read by filter alone. The other two are regression guards for the reasoning behind the API, which is the part that would be expensive to rediscover: - A record lacking a declared field is returned by `{userId}` alone and by nothing that also filters on that field. That is why an extended schema must not cover a keyspace holding records written without it — there is no filter-level workaround, since Upstash Search has no `$ne`. Without this test the prefix rule reads like style advice. - An unextended store still reads records written before `metadataSchema` existed, stores no extra fields, and leaves `metadata` undefined rather than `{}`. That is the non-breaking claim, asserted rather than asserted-in-prose. README documents it behind a details block: the schema, filtering, that values are stored top-level because Redis Search indexes JSON by path, and the own-prefix warning stated as data loss rather than a preference. `list`/`count` added to the method list.

Each suite here mints a `uniquePrefix`, so every run starts with an index that does not exist yet: the writes land first, `waitIndexing()` on a missing index is a silent no-op, and the first `recall()` is what provisions it reactively. That read then asserted immediately against an index whose backfill had not caught up, with no retry. Apply the ordering the two already-fixed suites use (chat-history, eve search-tools): provision in `beforeAll` via a throwaway `count()` — the `{count:-1}` sentinel makes the reactive wrapper create the index and wait — then seed, `waitIndexing()`, and read through a bounded `pollUntil` for residual lag. The miss assertion in "returns nothing when a query matches nothing" now confirms the record is visible *before* asserting the miss, so it can no longer pass because the doc simply had not been indexed yet. Test-only; no package behaviour changes.

The ai-sdk search-tools suite is what went red on the last CI run ("count tool counts matching documents": expected 1 to be >= 2) — it counted while the index had caught up with only one of the two docs the previous test seeded, and asserted once with no retry. Each suite now creates its index in `beforeAll` via a throwaway read (a missing index answers `count` with `{count:-1}` and `query` with `null`, either of which makes the reactive wrapper create it and retry), then seeds, waits, and reads through a bounded `pollUntil`. `reactive-index.test.ts` is deliberately left alone: it asserts on `createIndex` call counts against empty indexes, so it has no read-after-write assertion to race, and provisioning up front would defeat what it tests. Test-only; no package behaviour changes.

TypeScript has no partial type-argument inference, so this is the only arrangement that can actually check the two against each other: had the metadata type stayed the inferred-from-nothing first parameter, a schema passed as a value could never be compared to it. Where the derived type is too wide — a `s.string()` field holding a known union — the metadata type can still be given as a second argument, constrained to `MetadataOf` so it cannot contradict the schema. That is what the eve memory provider uses to keep `source: MemorySource` instead of `string`. The builder classes are not exported by `@upstash/redis`, so the built field type is recovered structurally (the single zero-arg method returning a `{type: …}` object); only the field-type-to-value mapping is restated from the library. `memory.types.test.ts` pins all of it with `@ts-expect-error` markers, which fail the build if an invalid usage becomes legal — reverting the two signatures turns 8 of them red. BREAKING CHANGE: `AgentMemory` is now `AgentMemory`. Callers naming the metadata type explicitly either drop the argument and let it infer from `metadataSchema`, or pass both as `AgentMemory`. Only released as part of the unshipped `metadataSchema` feature.

It now takes `MetadataFilter` like its callers, so an internal caller cannot pass a filter the schema does not describe either. The two remaining `as InferFilterFromSchema<…>` assertions stay, and the comments now say why rather than leaving it to be rediscovered: the index handle is typed with the base schema while the index also covers the declared metadata fields. Typing the handle with the full schema was tried and does not help — a value cannot be checked against a filter type built on an unresolved generic, so the cast only moves to the construction seam and the reads need one anyway.

Verified rather than assumed. Stubbing `fetch` and reading the token off each outgoing request, three calls send `[null, "", "tok-1"]` on 1.38.0 — every request one token behind — and `["", "tok-1", "tok-2"]` on 1.38.4. `packages/eve`'s `@upstash/redis` peer floor is raised `>=1.38.0` -> `>=1.38.4`, because `redisDocuments()` now relies on the fix; leaving it open would let a consumer reinstate the bug with no workaround left to catch it. Every dependency and devDependency pin moves to `^1.38.4`. `pnpm dedupe` collapses the second copy that `@upstash/core-analytics` (via `@upstash/ratelimit`) was holding at 1.38.0. The scripted lagging-client regression test is removed with the behaviour it pinned; its sibling now asserts the plain path — an absent document resolves in a single round trip. The `pollUntil`s elsewhere are for search-index lag, a different problem, and stay.

That is why supermemory and `fileMemory()` do not cache. We are that exception, so the cache stays. Recall is a live ranked query plus two live counts over a store the same turn writes to: `save_memory` adds a `source: "agent"` record, which is exactly what recall ranks, and the model can call it mid-turn; `forget_memory` flips `deleted`; capture appends the turn's messages; and a concurrent session on the same scope key can do any of it. Replaying `turn.started` after any of those would produce a different block and eve would reject the turn. The old comment justified the cache as "a live ranked query is not naturally stable", which reads like eve requires every provider to cache. It does not, and that framing invites deleting the cache on the next read of this file. Comments only — no behaviour change.

All six findings were real; the first is a behaviour bug, the rest are documentation that still describes the pre-redesign design. **`forget_memory` could refuse to redact a record that exists.** It listed one unranked page of live records (`limit: 50`) and filtered that page for the id, so once a scope held more live memories than a page, forgetting anything outside it returned `{redacted: false, reason: "no entry with that id"}` while the record stayed recallable — the user asks to forget something and is told it was never there. It now reads the key directly via a new `AgentMemory.get({userId, id})`, which no page can hide and which also sees records the index has not caught up with. Regression test seeds a full page *before* the target, so the target lands outside it; reverting to the page scan turns it red ("expected false to be true"). `AgentMemory.get` is a real addition to the core SDK: a direct-key read was missing, and looking a known id up through a bounded search was the only option. Docs corrected to match the shipped code: - the provider docstring and `prefix` JSDoc claimed the slot stores at `agentkit:memory` sharing `defineMemorySaveTool`'s index; it has owned `agentkit:memorySlot` and its own index since the schema gained indexed fields - the lifecycle tables in `memory/index.ts` and the changeset advertised capture at `compaction.requested` and a `rememberSessions` option; only `turn.completed` is registered and that option no longer exists - both eve-demo memory comments were wrong about `rememberMessages`, one saying capture is off by default and the other that `true` means `"all"`; it defaults to `true`, which means `"fromUser"` Claude-Session: https://claude.ai/code/session_01D3v2QieC7eC1EwhZk7KtKj --- .changeset/eve-redis-memory-slots.md | 25 +++++++-------- examples/eve-demo/agent/agent.ts | 6 ++-- examples/eve-demo/agent/memory/recall.ts | 5 +-- packages/eve/src/memory/index.ts | 7 +++-- packages/eve/src/memory/memory.test.ts | 38 +++++++++++++++++++++- packages/eve/src/memory/provider.ts | 40 +++++++++++++----------- packages/sdk/src/memory.ts | 40 +++++++++++++++++++----- 7 files changed, 112 insertions(+), 49 deletions(-) diff --git a/.changeset/eve-redis-memory-slots.md b/.changeset/eve-redis-memory-slots.md index 269c028..d484363 100644 --- a/.changeset/eve-redis-memory-slots.md +++ b/.changeset/eve-redis-memory-slots.md @@ -12,9 +12,9 @@ feature (`agent/memory/.ts`), because eve exposes two genuinely different closes eve's documented gap — with no `backend`, `fileMemory()` only resolves storage under `eve dev` (process-local) and on Vercel with a Blob store attached, and errors everywhere else. - **`redisMemory()`** — a full `MemoryProvider` over the SDK's `AgentMemory`: ranked BM25 recall at - `turn.started` / `compaction.completed`, automatic capture at `turn.completed` / - `compaction.requested`, plus `__save_memory` and `__forget_memory` tools bound to the - slot's locked scope.

The comments here asserted REST "is stateless and therefore has no WATCH/MULTI", which is half wrong and was never verified. The conclusion is unchanged: the compare-and-set still has to be a Lua `EVAL`. The accurate reason is narrower. A transaction queues its commands and hands back every result at `EXEC`, so nothing inside it can branch on a value it just read — `multi().get(k).set(k,"b").exec()` returns `["a","OK"]` with the `set` already done unconditionally. Conditioning a write on what was read is `WATCH`'s job, and `WATCH` is the part REST genuinely lacks: the server answers `ERR Command "WATCH" is not allowed in REST`, since watching spans requests and REST keeps no session between them. Corrected in the `documents.ts` module docstring, the comment above the `EVAL` call, the concurrent-writers test, and CLAUDE.md — which now records the measured behaviour of both, so the wrong version does not get written back. Comments only; no behaviour change.

Capture filtered its batch through a `Set` keyed on the normalized text alone. Under `rememberMessages: "all"` both halves of a turn are captured, and when the caller and the model say the same short thing — "thanks", "yes", "ok" — the second was dropped, so `read_session` returned half the turn. Nothing else forced that: `recordIdFor` already mixes in `source` and `subIndex`, so the two records have distinct keys and both would have stored fine. The batch filter is now keyed by source plus text, which still collapses a genuine repeat within one source. It mattered more than a stray duplicate because this transcript is meant to be gap-free: `forget_memory` redacts rather than deletes precisely so a reader never sees a silent hole and re-derives what was removed. A capture that quietly skipped an entry punched exactly that hole. Regression test drives an echoed turn through `"all"` and asserts both sources come back; reverting to the text-only key fails it with `expected [ 'userMessage' ] to deeply equal [ 'userMessage', 'agentMessage' ]`. CLAUDE.md still described capture at `turn.completed`/`compaction.requested` in three places, and the same bullet still described the pre-redesign record key and index name.
