Core Mechanism

Shared latent memory for agents: knowledge and reasoning patterns are encoded as dense vectors in a common semantic space. Agents write summaries, facts, and patterns with metadata; retrieval uses similarity search and hybrid filters to assemble relevant context for downstream reasoning. Memory consolidates over time via deduplication, clustering, and schema-preserving summaries to reduce redundancy and drift.

Workflow / Steps

Ingest: chunk artifacts (text/code/events) with stable IDs; attach provenance and timestamps.
Embed: generate embeddings with a consistent model/version; normalize and store vectors + metadata.
Index: build ANN index (e.g., HNSW/IVF/ScaNN) with filters over namespaces/agents/types.
Retrieve: query by semantic vector + keyword/struct filters; re-rank and diversify top-k.
Assemble: compress/summarize retrieved items into LLM-ready context with citations.
Write-back: persist new insights as atomic memory entries; avoid duplicating near-identical content.
Consolidate: schedule dedup, clustering, drift checks, and long-term summaries with TTL/pinning.

Best Practices

Use a single, versioned embedding model across agents; re-embed on model upgrades with canaries.

Chunk with semantic boundaries and overlap; store canonical IDs to deduplicate.

Hybrid retrieval (vector + keyword + metadata) and MMR/DR to improve relevance and diversity.

Add strict schemas: type, agent, task, source URI, timestamp, version, and PII flags.

Tune ANN parameters (HNSW M/ef, IVF nlist/nprobe) for p95 latency vs. recall; cache hot queries.

Periodic consolidation: near-duplicate removal, cluster summaries, and topic schemas.

Safety and privacy: redact PII, scope namespaces per tenant/agent, and enforce access policies.

Evaluate retrieval with labeled queries; track precision/recall@k and citation correctness.

When NOT to Use

Tasks solvable from model prior with acceptable quality and strict latency/cost constraints.
Domains requiring fully symbolic, auditable reasoning with minimal latent representation.
Highly regulated or sensitive data without strong governance, redaction, and isolation.
Very small, static knowledge where a curated prompt/template outperforms retrieval overhead.

Common Pitfalls

Embedding mismatch/drift across agents leading to poor cross-agent retrieval.
Index bloat from duplicate or overly granular chunks; no TTL or consolidation policy.
Over-retrieval causing token blowups; missing summarization/quotas and MMR.
Unlabeled data lacking provenance/citations; weak evals hide regressions.

Key Features

Shared latent space across agents with namespace and capability scoping

Semantic similarity search with hybrid filters and re-ranking

Dynamic consolidation (deduplication, clustering, long-term summaries)

Provenance, citations, and schema-enforced metadata

Online updates and background re-embedding/version migrations

Optional hybrid dense+keyword retrieval for precision on entities/codes

Support for cross-domain transfer via cluster-aware sampling

KPIs / Success Metrics

Retrieval precision/recall@k, MRR/NDCG; citation correctness rate.
Task success uplift vs. no-memory baseline; judge/win rate on eval sets.
Latency p50/p95 for embed/store/retrieve; memory hit rate and dedup ratio.
Storage growth vs. unique concepts; re-embedding backlog and drift metrics.

Token / Resource Usage

Embedding cost per chunk (batch where possible); cache embeddings for unchanged artifacts.
ANN query compute scales with ef/nprobe; tune k and apply filters to reduce candidates.
Summarization tokens for write-backs and consolidation; enforce context budgets.
Background jobs (dedup/re-embed) consume CPU/GPU; schedule off peak with quotas.

Best Use Cases

Multi-agent research/analysis assistants with cross-agent knowledge sharing.
Code intelligence and architectural memory across services and teams.
Customer support/product QA with evolving knowledge and citations.
Long-running projects that benefit from cumulative, consolidated reasoning patterns.
