memory-management

memory-management is a skill for Claude Code, Codex from hajekim/agentic-design-patterns-extension. It costs 418 tokens per session (3,504 once invoked), scanned A, a copy of memory-management, MIT.

A pattern for letting an AI agent retain useful information from the current task or from earlier sessions.

In plain words
What is it for?
Use it for conversation continuity, personalized responses, tracking multi-step tasks, recalling past sessions, and retrieval-augmented generation, which supplies relevant stored knowledge to an answer.
Why use it?
Without memory, each interaction starts with little or no knowledge of previous conversations, user preferences, or unfinished work.

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

memory-management 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 6d 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.

Memory Management Pattern

Overview

The Memory Management Pattern enables agents to retain and utilize information from past interactions, observations, and learning experiences. Without memory, every agent turn is isolated — the agent has no awareness of prior context. With effective memory management, agents can maintain conversation continuity, personalize responses, track task progress, and improve over time.

Core Principle: Give agents the ability to remember — short-term for the current interaction, long-term for knowledge that persists across sessions.

When This Skill Applies

Activate this pattern when:

  • Agents must maintain context across multiple conversation turns
  • User preferences or past behaviors should influence future responses
  • Multi-step tasks require tracking progress and intermediate results
  • Agents need to recall information from previous sessions
  • Personalization and continuity are key user experience requirements
  • RAG (Retrieval-Augmented Generation) is needed for knowledge-grounded responses

Rule of thumb: If an agent needs to "remember" anything beyond the current prompt — use Memory Management.

Memory Types

Short-Term Memory (Contextual Memory)

  • Lives within the context window of the current LLM call
  • Contains: recent messages, tool outputs, agent reflections, session state
  • Limited capacity: context windows have token limits
  • Ephemeral: lost when the session ends
  • Management strategies: summarize older segments, prioritize key information, use long-context models

Long-Term Memory (Persistent Memory)

  • Stored outside the agent's immediate context in external systems
  • Storage options: databases, knowledge graphs, vector databases
  • Semantic search: vector embeddings enable similarity-based retrieval
  • Persistent: survives session terminations, restarts, and time gaps
  • Use cases: user preferences, learned knowledge, historical records

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.
