Hermes current-turn memory provider with permanent semantic recall, nightly workflow digest, SQLite truth storage, and a LanceDB vector companion
Give Hermes durable memory that can follow the same user across windows/chats while keeping local scratch context from bleeding into the wrong place.
Current-turn recall · Permanent shared memory · Nightly workflow digest · Local scratch scopes · SQLite truth · LanceDB companion · Hybrid retrieval
scope-recall is a Hermes local memory provider built for current-turn recall and permanent semantic memory. Durable user/project/ops/memory facts are shared across windows/chats for the same user + agent identity; raw general turn captures stay local to the current chat/thread/session.
Version 1.0.5 is the nightly digest release for the documented V1 interfaces, packaged as a public release candidate for broader field testing. It keeps the V1 compatibility contract in docs/stability.md while adding a profile-scoped daily conversation digest that can promote task workflows, tool-chain summaries, and important daily facts into SQLite truth without storing raw system/tool output.
It uses a two-layer design:
- SQLite truth store for durable local records and deterministic auditing
- LanceDB vector companion for semantic retrieval and hybrid ranking
This replaces the old lancepro naming, which was misleading because the earlier implementation was SQLite-only.
- Truth stays inspectable: SQLite remains the authoritative store; vectors are rebuildable.
- Recall is current-turn scoped: retrieval is based on the active query, not stale queued context from the previous topic.
- Durable memory travels deliberately:
user,memory,project, andopsfacts can follow the same user + agent identity across windows/chats. - Scratch context stays local: raw
generalturn captures stay inside the current chat/thread/session boundary. - Operator actions fail closed: cross-scope export/dedupe/govern/repair paths require explicit maintenance mode.
- Install remains practical: hosted embeddings are used when configured, while deterministic
local-hashkeeps no-key bootstrap available.
Most agent memory pain is not just "wrong memory was recalled". The bigger user-facing failure is often "the agent forgot everything when I opened a new window." scope-recall therefore separates durable facts from local scratch context:
- user preferences, project facts, ops notes, and explicitly stored memories follow the same user + agent identity across chats/windows
- raw/general turn captures remain local to the current chat/thread/session so one group's temporary chatter does not contaminate another group
- current-turn recall searches only for memories relevant to the active query, avoiding stale previous-turn injection
- the SQLite truth store remains auditable, and LanceDB is only a rebuildable semantic companion
scope-recall is built around a simple rule:
Recall the relevant durable memory for the current query, while keeping local scratch context inside the current runtime scope.
You: "For this memory-provider project, SQLite is the source of truth."
(later, in another window/chat)
Agent: "I don't have that context here." ❌
You: "What did we decide for this Hermes memory provider?"
Agent: recalls the durable project memory from SQLite truth/LanceDB companion and answers from the relevant context. ✅
Group A: "Temporary note: restart this group's test bot only."
(later, in Group B)
Agent: applies Group A's temporary note in Group B. ❌
scope-recall keeps that temporary general scratch row local while still sharing durable user/memory/project/ops facts.
| Area | What scope-recall V1 provides |
|---|---|
| Current-turn recall | prefetch(query) retrieves against the active user query; queue_prefetch() is intentionally a no-op |
| Storage authority | SQLite is the durable truth; LanceDB is rebuildable companion state |
| Hybrid retrieval | SQLite lexical/FTS candidates + LanceDB semantic candidates + bounded prompt rendering |
| Entity/context layer | SQLite entity index, entity probe/related tools, compact query context, trust feedback |
| Nightly digest | Profile-scoped daily consolidation for durable facts, workflow summaries, and sanitized tool-chain evidence |
| Memory scope model | shared durable scope for user/project/ops/memory facts; local scope for general scratch captures |
| Built-in memory integration | Hermes curated USER.md / MEMORY.md are live-read, not mirrored into SQLite. In gateway contexts with an explicit user_id, curated-file recall is opt-in/allowlisted to avoid cross-user leakage from global profile files. |
| Governance | deterministic exact dedupe, conservative near-duplicate merge, filtering, metadata, decay review |
| Migration | local lancepro auto-migration; OpenClaw memory-lancedb-pro import is explicit |
| Offline bootstrap | deterministic local-hash fallback when hosted embeddings are unavailable |
scope-recall works as a standalone Hermes memory provider. You can install only this plugin and get scoped current-turn recall, SQLite truth storage, LanceDB companion retrieval, and local scratch isolation.
For stricter post-turn knowledge governance, pair it with turn-closure-audit.
The two plugins solve adjacent problems:
| Plugin | Role |
|---|---|
scope-recall |
decides what memory should be recalled for the current turn |
turn-closure-audit |
audits a completed turn and writes redacted review candidates when important knowledge may not have been retained |
This pairing is useful for long-lived Hermes agents where you want both scoped recall during a conversation and conservative review after the turn ends. It is optional, not a runtime dependency.
cd "$HERMES_HOME/plugins"
git clone https://github.com/410979729/scope-recall.git scope-recall
cd scope-recall
python -m pip install -e .Then configure Hermes to use the provider name:
memory:
provider: scope-recallFor a local smoke check after installation:
hermes memory statusCurrent Hermes plugin discovery expects an unpacked plugin directory. scope-recall V1 targets the current Hermes runtime line, which requires Python 3.11 or newer. If you download a release archive instead of cloning:
- unpack it as
$HERMES_HOME/plugins/scope-recall/ - run
python -m pip install -e "$HERMES_HOME/plugins/scope-recall" - set
memory.provider: scope-recall - restart/reload the Hermes process that should use the provider
- verify with
hermes memory status
Important boundary:
- the wheel build is verified for packaging sanity and importability
- the primary Hermes install shape for V1 is still an unpacked local plugin directory
- do not read wheel build success as proof that Hermes can discover or install this plugin directly from a wheel alone
The shipped config.json defaults to hybrid retrieval with a hosted OpenAI-compatible Gemini embedding path and a deterministic offline fallback.
Minimal default shape:

"auto_capture": true,

"maintenance_tools_enabled": false,

}
}Credential rule:
- put real API keys in your private environment, not in
config.json - if no configured key is available,
scope-recallfalls back tolocal-hash
Currently implemented:
| Provider | Use case | Notes |
|---|---|---|
openai-compatible |
Gemini/OpenAI-compatible embedding APIs | Default configured path; supports env-based API key lookup |
openai |
Direct OpenAI embeddings | Useful when you do not need a custom compatible endpoint |
sentence-transformers |
Local Hugging Face / SentenceTransformers models | Good for local semantic embeddings when installed |
local-hash |
Offline fallback | Deterministic degraded fallback, not a true semantic model |
local-debug |
Tests/debugging | Tiny deterministic test embedder |
Provider aliases local-model, local-embedding, and huggingface resolve to the sentence-transformers backend.
scope-recall does not split all memory by every group or tiny window. It uses two provider-owned scopes:
- Shared durable scope:
platform + agent_workspace + agent_identity + user_id. Rows with targetsuser,memory,project, andopsare stored here, so they can be recalled across chats/windows for the same user and agent. - Local runtime scope: shared durable scope plus
gateway_session_key, orchat_id/thread_id. Rows with targetgeneralstay here, so temporary group/topic/session chatter does not bleed elsewhere. - Accessible scope set: normal recall and scoped tool actions can see the current local scope plus the shared durable scope; they cannot see another user, sibling agent identity, or another local chat/thread/session scratch scope.
This aims at the common expectation: "if I gave the agent durable information before, it should remember it later," without making every scratch line globally visible forever.
When scope-recall is active, Hermes memory has two intentional authority zones:
| Layer | Storage | Purpose | How recall sees it |
|---|---|---|---|
| Hermes curated memory | $HERMES_HOME/memories/USER.md, $HERMES_HOME/memories/MEMORY.md |
User profile and durable hand-curated notes managed by Hermes built-in memory | Live-read during recall; not mirrored into SQLite; gateway user_id contexts require curated-memory opt-in/allowlist |
| Scope Recall provider memory | $HERMES_HOME/scope-recall/memory.sqlite3 + $HERMES_HOME/scope-recall/lancedb/ |
Provider-owned shared durable memories plus local scratch captures, scope metadata, lexical/vector retrieval | SQLite truth + optional LanceDB companion ranking |
Key principle:
SQLite is the truth source for provider-owned rows. Hermes curated memory files remain their own truth source. LanceDB is a rebuildable retrieval companion, not the authority.
This is deliberate. Mirroring curated memory writes into SQLite can leave stale duplicates after replace/remove operations. Live-reading curated memory keeps Scope Recall aligned with Hermes native memory behavior. Because those curated files are profile-global, live-read recall defaults to single-user: it is active for single-user/no-user_id runtimes and disabled for explicit gateway user_id contexts unless curated_memory.mode is set to profile-global or explicit-users with matching allowed_user_ids.
Under the active Hermes profile:
$HERMES_HOME/scope-recall/memory.sqlite3$HERMES_HOME/scope-recall/config.json$HERMES_HOME/scope-recall/lancedb/
Legacy lancepro storage is migrated forward on first initialization when present.

SQLite is the authoritative provider-owned store.
It keeps:
- raw memory rows
- scope metadata
- lexical FTS index
- timestamps for auditing and migration
Why SQLite stays authoritative:
- deterministic local persistence
- easy schema inspection
- simple migration/backup story
- safer open-source baseline than tying truth directly to a vector backend
LanceDB is a companion retrieval index, not the truth source.
It stores retrieval-ready fields copied from SQLite plus a vector column:
idscope_idsourcetargetcontentsummaryupdated_atvector
Configured default embedder targets the Gemini OpenAI-compatible embeddings API:
provider: openai-compatiblemodel: gemini-embedding-001dimensions: 3072
Runtime fallback remains available:
- if the configured API embedder is unavailable, the plugin falls back to
local-hash(256dims) - this keeps first-boot/local operation working even without external API keys, while preserving a higher-quality default config for instances that do provide credentials
prefetch(query)retrieves against the current user queryqueue_prefetch()is intentionally a no-op- this avoids stale next-turn injection from the previous topic
user,memory,project, andopsrows are durable shared memories for the same user + agent identity- they can be recalled from another chat/window when the new query is semantically relevant
generalrows remain local scratch context for the current chat/thread/session- ID-based updates/deletes/merges are restricted to the current accessible scope set, not global row ids
scripts/nightly-digest.py is a plugin-owned batch path for daily memory consolidation. It reads the profile's active Hermes state.db first, falls back to legacy lcm.db, and scans the selected local date by message timestamps. Raw system rows and raw tool outputs are not stored. For task sessions, the digest keeps a sanitized tool-chain summary so repeated engineering workflows can be recalled later as workflow memory.
Typical smoke run:
python scripts/nightly-digest.py --hermes-home "$HERMES_HOME" --date 2026-06-01 --dry-run --extractor heuristic --verboseProduction runs default to the LLM extractor. The script reads model/base URL/API key information from the Hermes profile config and .env, with SCOPE_RECALL_DIGEST_API_KEY available as an explicit override. If the LLM path returns no usable candidates for a session, the digest falls back to heuristic candidates for that session. Actual writes use SQLite truth rows, FTS/entity sync, digest run/source ledgers, semantic skip/update/insert decisions, exact duplicate cleanup, and LanceDB companion upsert when vector indexing is enabled.

score fusion + freshness hints + prompt budget
Supported retrieval modes:
lexicalvectorhybrid(default)
Default hybrid weights:
- lexical:
0.45 - vector:
0.55
Guardrail: if only one side has a score, that side is used directly instead of being unfairly damped by a missing partner score.
Scope is built from:
platformagent_workspaceagent_identityuser_idgateway_session_keywhen available- otherwise
chat_id - plus
thread_idwhen present
This prevents raw identifiers containing delimiters from colliding with split scope fields, and preserves the intended split: durable facts can move with the same user + agent identity, while local scratch rows do not leak across different groups, chats, sessions, or topics.
SQLite is the cardinality authority. During vector sync, the provider compares SQLite ids with LanceDB ids, deletes stale vector rows, collapses duplicate physical rows by id, and embeds missing/changed rows. If LanceDB delete/upsert fails, the SQLite write is preserved and vector state becomes needs_repair instead of surfacing the truth-row write as failed.
scope_recall_stats reports:
vector.row_count— physical LanceDB row countvector.unique_id_count— distinct vector idsvector.duplicate_row_count— extra physical rows beyond one row per idvector.status—ready,degraded,needs_repair,disabled, orerror
When vector.index_general=false (the default), local general scratch rows are not expected in LanceDB. A healthy synced companion should have vector.unique_id_count == vector.row_count, vector.duplicate_row_count == 0, and vector ids matching the configured vector-indexed provider rows.
For deeper maintenance:
python scripts/repair.vector_index.py --hermes-home "$HERMES_HOME" --dry-run
python scripts/repair.vector_index.py --hermes-home "$HERMES_HOME"Provider-owned captures apply a deterministic first line of governance before SQLite writes:
- exact normalized-content dedupe within
(scope_id, target) - conservative semantic near-duplicate merge for
user,ops, andprojectmemories - conflict preservation when a near-duplicate contains negation / supersession language
- rules-based smart extraction from user turns into preference / ops / project fact candidates
- metadata classification for category, tier, confidence, sensitivity, and expiry review
- noisy maintenance/system prompt filtering
- trivial reply filtering
- obvious secret-bearing text filtering
- overlong prompt-block filtering through
capture_hard_max_chars - governance review through
scope_recall_govern, including core/working/archive tier counts and decay candidates
This is a local deterministic governance layer, not a remote LLM extraction pipeline. It intentionally stays conservative so SQLite remains auditable truth and conflicting memories are preserved rather than silently overwritten.
Primary-agent default tools:
scope_recall_store
scope_recall_search
scope_recall_context
scope_recall_probe
scope_recall_related
scope_recall_feedback
scope_recall_forget
scope_recall_update
scope_recall_merge
scope_recall_export
scope_recall_stats
Operator-only maintenance tools are hidden from the default schema and require maintenance_tools_enabled=true:
scope_recall_dedupe
scope_recall_govern
scope_recall_hygiene
scope_recall_repair
scope_recall_hygiene is read-only. It reports runtime-wrapper noise, assistant scratch prose, duplicate dedupe keys, very short/long rows, general rows present in the vector companion, likely promotion candidates, and likely delete candidates. It does not delete, merge, promote, or rewrite rows.
For an offline SQLite report without exposing the maintenance tool to agents:
python scripts/report.hygiene.py --db "$HERMES_HOME/scope-recall/memory.sqlite3" --format markdownDestructive cleanup is intentionally out-of-band: use the hygiene report first, then require an explicit operator decision before running any separate delete/merge/dedupe action. The shipped hygiene path is dry-run/report-only.
scope_recall_export defaults to the current accessible scope set: local scratch scope plus shared durable scope. Passing scope_only=false is an operator maintenance action and fails closed unless maintenance_tools_enabled=true.
Backward-compatible aliases are still accepted internally for old lancepro_* tool names during transition.
Example primary-agent tool calls:
# Store provider-owned memory. ops/user/memory/project become shared durable rows; general stays local scratch.
store = scope_recall_store(
content="This project deploys with uv run app.",
target="ops",
)
# Search the current accessible scope set: local scratch plus shared durable memory.
results = scope_recall_search(
query="How does this project deploy?",
limit=3,
)
# Inspect truth/vector health.

On first boot, if $HERMES_HOME/lancepro/ exists and $HERMES_HOME/scope-recall/ does not yet contain the new DB/config, the provider:
- copies the legacy SQLite database into the new location
- copies
config.jsonforward - records migration info in
scope_recall_stats
OpenClaw memory-lancedb-pro history is handled separately as an explicit import problem, not automatic compatibility.
See:
docs/migration.mddocs/differences-from-memory-lancedb-pro.mdscripts/import.openclaw.memory_lancedb_pro.py
Do not point scope-recall directly at an OpenClaw .lance directory and call it done. Old vector stores must be transformed into SQLite truth rows before the companion vector index is rebuilt.
scope-recall was inspired by good public ideas in OpenClaw memory-lancedb-pro, especially current-turn recall, scoped memory boundaries, hybrid retrieval, and memory hygiene. It is not a line-for-line port and it does not claim feature parity.
| Area | OpenClaw memory-lancedb-pro |
scope-recall V1 |
|---|---|---|
| Host agent | OpenClaw | Hermes |
| Truth model | LanceDB-centric OpenClaw memory pipeline | SQLite truth + LanceDB companion index |
| Recall timing | OpenClaw auto-recall hook model | Hermes prefetch(query) current-turn recall; no queued next-turn recall |
| Curated memory | Separate OpenClaw markdown/journal behavior | Hermes USER.md / MEMORY.md live-read and kept authoritative |
| Smart extraction | LLM-backed created/merged/skipped style in upstream beta line | deterministic/rules-based extraction and conservative merge |
| Lifecycle | Weibull decay / tier promotion concepts upstream | deterministic metadata classification and decay/governance review; no full LLM summarization tier pipeline |
| Migration | OpenClaw-native data path | explicit importer from OpenClaw LanceDB shape into SQLite truth |
Honest claim boundary:
scope-recallis a Hermes local memory provider for current-turn recall with SQLite truth storage, LanceDB vector companion retrieval, strong runtime scope isolation, deterministic write-time governance, and explicit migration boundaries.
It should not be described as:
- a drop-in replacement for OpenClaw
memory-lancedb-pro - a direct reuse wrapper around old
.lancestores - full feature parity with upstream LLM-backed governance and lifecycle orchestration
Check that the running provider is scope-recall, not the deprecated lancepro name, and remember that live Hermes runtime freshness requires a process restart/reload after code changes.
hermes memory statusRun the repair script. SQLite remains truth; the vector layer is rebuildable companion state.
python scripts/repair.vector_index.py --hermes-home "$HERMES_HOME" --dry-run
python scripts/repair.vector_index.py --hermes-home "$HERMES_HOME"The provider should degrade to local-hash. That keeps the system usable but lowers semantic quality. Set SCOPE_RECALL_GEMINI_EMBEDDING_API_KEY in your private environment to use the configured hosted path.
That is expected. OpenClaw history must be explicitly imported into SQLite truth rows before the companion vector index is rebuilt.
Release checks prove the source tree and artifact. They do not prove a running Hermes gateway has loaded the new plugin. Restart/reload the target Hermes process and verify with a real runtime smoke test before claiming live-runtime freshness.
- vector sync is incremental by stable row id /
updated_at, with duplicate-id/stale-row repair during normal sync;scripts/repair.vector_index.pycan rebuild the LanceDB companion from SQLite truth when deeper storage hygiene is needed - semantic merge is intentionally conservative and rules/scoring-based; it is not a general-purpose contradiction resolver or LLM reasoning layer
- write-time smart extraction is rules-based for common preference / ops / project-fact sentences; nightly digest adds a separate LLM/heuristic batch consolidation path, but it is not full OpenClaw-style always-on created/merged/skipped lifecycle parity
- fallback
local-hashis only a degraded offline path, not a true semantic model - old
lanceprodirectory still exists as a compatibility shim during the V1 transition window - the supported Hermes install shape is still an unpacked plugin directory; the wheel is verified as a package artifact, not as a Hermes discovery mechanism
