Memory & evidence
How agents remember, what gets promoted, how knowledge is grounded.
AI Agent Memory Is Broken: Designing Multi-Layer Memory for Production AI Agents
A production guide to AI agent memory architecture: designing long-term memory for AI agents across working, episodic, semantic, procedural, and organizational layers. Why RAG is not memory, why vector databases are not memory, and how governed, situation-aware memory prevents memory poisoning in enterprise AI agents.
Give Claude Code, Cursor, and Codex Persistent, Auditable Memory
Coding agents are brilliant and amnesiac. SecondBrain's open-source Memory API gives Claude Code, Cursor, Codex, and ChatGPT shared, local-first memory over HTTP and MCP — where every answer carries a citation back to the source chunk.
The Identity Layer: Agents Need Two Identities, Not One
Why governed agent runs need entity identity, delegated user identity, and workload identity in the same RunContext.
Promotion-Aware Memory: Capture, Review, Promote, Recall in Code
A build-along for agent memory: capture, review, promote, recall, contradiction checks, and governed memory writes.
Context Graphs: Decision Lineage as a System of Record
How hash-chained DecisionRecords turn execution-time context into a queryable lineage graph for why an agent acted.
