agent-memory-systems

agent-memory-systems is a skill for Claude Code, Codex from ranbot-ai/awesome-skills. It costs 0 tokens per session (504 once invoked), scanned A, original, no licence file.

A guide to designing memory systems for AI agents, including short-term memory in the context window and long-term memory stored for later use.

In plain words
What is it for?
Use it to study or design memory architecture for agents, including how they retain and retrieve information across interactions.
Why use it?
It addresses the problem of an agent starting each interaction without access to relevant earlier information.

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

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 2d 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.

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 ranbot-ai/awesome-skills (6 stars, last pushed today), with no licence file. It costs nothing until one of its globs matches a file; then it loads 504 tokens. 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 2026-08-31.
