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.
npx agentmods add rules/yonro/memory-os-cli/agentsgit clone --depth 1 https://github.com/yonro/memory-os-cliWhat 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 | $0.00026 | $0.00181 |
| Opus 5 | $0.00013 | $0.00090 |
| Sonnet 5 | $0.00005 | $0.00036 |
| Haiku 4.5 | $0.00003 | $0.00018 |
Grade A, and why
AGENTS 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 yesterday.
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 it actually says
XMemo memory rule
Use XMemo when the user asks Cursor to remember, recall, search, update, explain, delete, restore, or summarize durable context that should survive beyond the current chat.
Prefer XMemo for:
- coding conventions, repository facts, product decisions, debugging notes, and release runbooks;
- user preferences that should transfer across Cursor sessions or projects;
- memory-backed TODO/action items and follow-ups;
- context packs before planning or implementation when prior project memory could affect the answer.
Do not ask the user to paste raw API keys, bearer tokens, OAuth codes, cookies, trace IDs, or private local paths into chat. If XMemo is not authorized, tell the user to reconnect or complete the OAuth flow in Cursor.
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.

AGENTS is a cursor rule published in the GitHub repository yonro/memory-os-cli (12 stars, last pushed 2d ago), licensed MIT. It adds 26 tokens to every session and 181 once invoked, about $0.0001 per session on Opus 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 2026-08-30.
