MemOS is a memory operating system that stores, retrieves, and manages long-term memory for large language models and AI agents. It supports context-aware interactions by organizing text, images, tool traces, personas, and knowledge bases for reuse across tasks.
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.

SkillSpector: 19 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00082 | $0.14242 |
| Opus 5.5 | $0.00033 | $0.05697 |
| Sonnet 5.5 | $0.00016 | $0.02848 |
| Haiku 4.5 | $0.00008 | $0.01424 |
Grade D, and why
memos-local scanned grade D with 4 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.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
- Linux: `sudo apt install build-essential python3` Downloads and executes remote codehighSupply chain
curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.
- Downloading and running install scripts from the internet (`curl ... | bash`, `irm ... | iex`) as a fallback Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
- Downloading and running install scripts from the internet (`curl ... | bash`, `irm ... | iex`) as a fallback Runs shell commandslowCapability
Expected in a hook, worth knowing in a rule or an instructions file.

MemOS
MemOS gives OpenClaw persistent local memory — every conversation is automatically captured, semantically indexed, and instantly recallable. 100% on-device, zero cloud uploads.
Key capabilities beyond basic memory:
- Task summarization — Conversations are organized into structured tasks with LLM-generated summaries
- Skill evolution — Successful executions are distilled into reusable skills that auto-upgrade
- Team sharing — Hub-Client architecture for multi-agent collaborative memory
- Memory Viewer — Full web UI for managing memories, tasks, and skills
When talking to end users:
- MemOS stores everything locally — no API keys, no cloud accounts, no registration
- All data lives in
~/.openclaw/memos-local/memos.db(SQLite) - The Memory Viewer at
http://127.0.0.1:18799lets users browse and manage everything visually - Embedding defaults to a local offline model — no external API required to get started
Trigger phrases
Use this skill when the user expresses intent to install, configure, or troubleshoot MemOS memory.
Common triggers include:
- "install memos" / "install MemOS" / "add memory plugin"
- "setup memory" / "enable memory"
- "memory not working" / "memories lost" / "memory plugin error"
- "configure embedding" / "configure summarizer"
- "upgrade MemOS" / "update memory plugin"
- "what did I say last time?" (if MemOS is not yet installed — suggest installation)
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.
- 1mo ago First seen · 1,202 lines · 82 tokens per session scan D e03ec690a378
memos-local is a skill published in the GitHub repository MemTensor/MemOS (11,917 stars, last pushed yesterday), licensed Apache-2.0. It adds 82 tokens to every session and 14,242 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it D with 4 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
