Agent Memory

Open JSONConfidence: EditorialLast updated Jun 30, 2026

Current Answer

Mechanisms that let agents retain and recall project facts across sessions — memory servers, context files, caches.

Implementation Consequence

Without memory, every session re-learns the project. With bad memory, every session inherits stale facts. The schema and eviction policy are the product.

Wearing the Agent: From Group Chats to Glasses — Sai Krishna Rallabandi
AI Engineer · 2026-07-29

Shared agents need a different harness: action-boundary security, selective group memory, per-user privacy, and routing that decides both who receives information and when the agent should speak.

UniMem: Complementary Episodic-to-Parametric Memory for Boundary-Agnostic Task Streams
arXiv · 2026-07-28

UniMem routes novel experience into retrieval memory and consolidates recurring patterns into expandable parameters, offering a design for agents that learn across unlabelled task streams.

MemLens: A Value-Aware Memory Management System with Interactive Analytics for LLM-based Agents
arXiv · 2026-07-28

MemLens scores individual agent memories, stores them by value, and exposes quality, latency, and token tradeoffs—an inspectable alternative to retaining every interaction equally.

Netflix’s performance-agent playbook feeds production profiles and exact deployed code to agents, then relies on canaries and engineers to validate proposed optimizations.

Eviction as Estimation: A Fixed-Lag Smoothing View of Test-Time Memory, and When Measuring Beats Accumulating
arXiv · 2026-07-27

A delayed KV-eviction policy helps when memory reuse is sharp and observable, but loses its edge on natural-text benchmarks—a useful warning for agent-memory claims.

Citation Needed: Provenance for LLM-Built Knowledge Graphs — Daniel Chalef, Zep AI
AI Engineer · 2026-07-23

LLM synthesis breaks simple source pointers when facts merge, change, or outlive one input. Model provenance inside the context graph so agents can filter trust, debug derivation, and apply deletion policies.

WTF Is the Context Layer? The Missing Infrastructure for Production Agents — Prukalpa Sankar
AI Engineer · 2026-07-14

Atlan’s agent experiments argue for shared, versioned context instead of per-agent memory: a portable layer for business facts, skills, norms, retrieval, and feedback across changing harnesses.

TencentCloud/TencentDB-Agent-Memory
GitHub

An open-source memory hub turns agent conversations, workflows, docs, and code into governed assets that can be reused across sessions and roles, reducing repeated project setup.

The Factory That Dreams: 39 AI Agents, No Framework - Rushabh Doshi, Machinecraft

A 100-person factory built a multi-agent sales system around organized company memory, specialist roles, and human approval. The useful pattern is retrieval and governance, not custom model training.

eve’s Chat SDK channel lets one agent span messaging adapters while retaining threads, approval cards, proactive sends, webhook handling, and overridable defaults.

Effective harnesses for long-running agents

Anthropic's harness pattern for multi-session agents: an initializer sets up the env, a JSON feature list, and progress files; each session then ships one feature, verified end-to-end and committed to git.

GitHub

ECC packages skills, hooks, memory, orchestration, and security controls for multiple coding-agent harnesses, but its breadth makes selective installation and verification essential.

Agent-Ready Context

Persist per-project facts in a small auditable schema. Watch for unbounded growth. Context caching (Gemini) and memory servers (mcp-memory) are complementary, not competing.
