Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00051 | $0.06843 |
| Opus 5 | $0.00026 | $0.03422 |
| Sonnet 5 | $0.00010 | $0.01369 |
| Haiku 4.5 | $0.00005 | $0.00684 |
Grade A, and why
agent-memory-systems 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 10d 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.
This is a copy
98% identical to agent-memory-systems — 1,052 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Agent Memory Systems
Memory is the cornerstone of intelligent agents. Without it, every interaction starts from zero. This skill covers the architecture of agent memory: short-term (context window), long-term (vector stores), and the cognitive architectures that organize them.
Key insight: Memory isn't just storage - it's retrieval. A million stored facts mean nothing if you can't find the right one. Chunking, embedding, and retrieval strategies determine whether your agent remembers or forgets.
The field is fragmented with inconsistent terminology. We use the CoALA cognitive architecture framework: semantic memory (facts), episodic memory (experiences), and procedural memory (how-to knowledge).
Principles
- Memory quality = retrieval quality, not storage quantity
- Chunk for retrieval, not for storage
- Context isolation is the enemy of memory
- Right memory type for right information
- Decay old memories - not everything should be forever
- Test retrieval accuracy before production
- Background memory formation beats real-time

Tooling
Memory_frameworks
- LangMem (LangChain) - When: LangGraph agents with persistent memory Note: Semantic, episodic, procedural memory types
- MemGPT / Letta - When: Virtual context management, OS-style memory Note: Hierarchical memory tiers, automatic paging
- Mem0 - When: User memory layer for personalization Note: Designed for user preferences and history
Vector_stores
- Pinecone - When: Managed, enterprise-scale (billions of vectors) Note: Best query performance, highest cost
- Qdrant - When: Complex metadata filtering, open-source Note: Rust-based, excellent filtering
- Weaviate - When: Hybrid search, knowledge graph features Note: GraphQL interface, good for relationships
- ChromaDB - When: Prototyping, small/medium apps Note: Developer-friendly, ~20ms p50 at 100K vectors
- pgvector - When: Already using PostgreSQL, simpler setup Note: Good for <1M vectors, familiar tooling
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.

agent-memory-systems is a skill published in the GitHub repository humaisali/Awesome-AI-Skills (5 stars, last pushed 1mo ago), licensed MIT. It adds 51 tokens to every session and 6,843 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 98% identical to agent-memory-systems, differing in 1,052 lines, and is treated as a copy.
