agentdb-persistent-memory-patterns

agentdb-persistent-memory-patterns is a skill for Claude Code from DNYoussef/context-cascade. It costs 20 tokens per session (1,783 once invoked), scanned A, original, MIT.

A set of patterns for giving AI agents persistent memory across sessions. It covers memory design, long-term storage, pattern learning, and context management for stateful agents, chat systems, and assistants.

In plain words
What is it for?
Use it to design memory schemas, store information across sessions, retrieve useful context, and build assistants that learn from earlier interactions.
Why use it?
It helps prevent agents from losing relevant history whenever a session ends or a new conversation begins.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agentdb-persistent-memory-patterns scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AgentDB Persistent Memory Patterns


LIBRARY-FIRST PROTOCOL (MANDATORY)

Before writing ANY code, you MUST check:

Step 1: Library Catalog

  • Location: .claude/library/catalog.json
  • If match >70%: REUSE or ADAPT

Step 2: Patterns Guide

  • Location: .claude/docs/inventories/LIBRARY-PATTERNS-GUIDE.md
  • If pattern exists: FOLLOW documented approach

Step 3: Existing Projects

  • Location: D:\Projects\*
  • If found: EXTRACT and adapt

Decision Matrix

Match Action
Library >90% REUSE directly
Library 70-90% ADAPT minimally
Pattern exists FOLLOW pattern
In project EXTRACT
No match BUILD (add to library after)

Overview

Implement persistent memory patterns for AI agents using AgentDB - session memory, long-term storage, pattern learning, and context management for stateful agents, chat systems, and intelligent assistants.

SOP Framework: 5-Phase Memory Implementation

Phase 1: Design Memory Architecture (1-2 hours)

  • Define memory schemas (episodic, semantic, procedural)
  • Plan storage layers (short-term, working, long-term)
  • Design retrieval mechanisms
  • Configure persistence strategies

Phase 2: Implement Storage Layer (2-3 hours)

  • Create memory stores in AgentDB
  • Implement session management
  • Build long-term memory persistence
  • Setup memory indexing

Phase 3: Test Memory Operations (1-2 hours)

  • Validate store/retrieve operations
  • Test memory consolidation
  • Verify pattern recognition
  • Benchmark performance

Phase 4: Optimize Performance (1-2 hours)

  • Implement caching layers
  • Optimize retrieval queries
  • Add memory compression
  • Performance tuning

Phase 5: Document Patterns (1 hour)

  • Create usage documentation
  • Document memory patterns
  • Write integration examples
  • Generate API documentation

Quick Start

import { AgentDB, MemoryManager } from 'agentdb-memory';

// Initialize memory system
const memoryDB = new AgentDB({
  name: 'agent-memory',
  dimensions: 768,
  memory: {
    sessionTTL: 3600,
    consolidationInterval: 300,
    maxSessionSize: 1000
  }
});

const memoryManager = new MemoryManager({
  database: memoryDB,
  layers: ['episodic', 'semantic', 'procedural']
});

// Store memory
await memoryManager.store({
  type: 'episodic',
  content: 'User preferred dark theme',
  context: { userId: '123', timestamp: Date.now() }
});

// Retrieve memory
const memories = await memoryManager.retrieve({
  query: 'user preferences',
  type: 'episodic',
  limit: 10
});

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

agentdb-persistent-memory-patterns is a skill published in the GitHub repository DNYoussef/context-cascade (32 stars, last pushed 3mo ago), licensed MIT. It adds 20 tokens to every session and 1,783 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
