What is xmemo-memory?

A persistent memory skill for agents that stores information across sessions and projects, including restart continuity, tasks, and expenses.

Use it to remember, recall, search, and preserve information, manage TODOs and expenses, or diagnose XMemo when MCP tools are unavailable.

It prevents useful context from being lost when a session ends and includes commands for checking the service and authentication.

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.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 1 finding, up to medium

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 →

medium Excessive Agency · line 118
Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.

Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00068	$0.04099
Opus 5.5	$0.00027	$0.01640
Sonnet 5.5	$0.00014	$0.00820
Haiku 4.5	$0.00007	$0.00410

Security

Grade A, and why

xmemo-memory 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.

The scan reads SKILL.md. This mod also ships 20 executable files (scripts/commands/account.mjs, scripts/commands/auth-login.mjs, scripts/commands/auth-manage.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

XMemo Memory

Give your agent durable memory that survives across sessions, projects, and tools.

First Successful Run

After ClawHub installs this Skill, follow First-run sign-in below:

First-run sign-in (keep it short)

When no credential exists, follow this exact sequence:

Ask once in the user's language using this canonical first-message template (translate when addressing the user in another language, but keep the template in English): "XMemo is your personal cloud memory — it lets AI remember your projects, preferences, and todos across sessions and tools, so you never have to repeat yourself. Using XMemo requires an account; you can create a new account or sign in to an existing one in your browser. Sign in or create an account to get started?" Show only this simple introduction and login question first, without doctor, MCP, token, commands, diagnostics, or technical setup.
On yes: run node scripts/xmemo-skill.mjs login --allow-plaintext directly so output is visible while the command is waiting (for example a background task or streaming shell). As soon as the verification URL and one-time code appear, show only those plus "approve it in your browser" — nothing else. Then wait for the command to exit. A short tool timeout must not kill it before approval or expiry.
When login succeeds: run node scripts/xmemo-skill.mjs auth status --verify, tell the user in one line that XMemo is connected, and continue the original task. Silently run node scripts/xmemo-skill.mjs profile --status later --if-unset with no user prompt, so the existing recall re-offer turns on.
On no: do not start login or create temporary access; continue the original task without XMemo; do not ask again in the same session unless the user brings it up.
Do not explain runtime selection, doctor details, secret-store setup, or other features during sign-in unless the user asks.

Diagnostics and Advanced Setup

For troubleshooting or non-interactive environments:

Check public service reachability: node scripts/xmemo-skill.mjs doctor --anonymous
For account-backed memory, prefer an XMEMO_KEY supplied by a managed secret store (see references/auth-setup.md).
Inspect or verify credentials: node scripts/xmemo-skill.mjs auth status --verify

xmemo-memory is a skill published in the GitHub repository yonro/memory-os-cli (12 stars, last pushed today), licensed MIT. It adds 68 tokens to every session and 4,099 once invoked, about $0.0003 per session on Opus 5.5. 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.

Use Perenna when a non-trivial task may depend on prior decisions or preferences, when durable knowledge should survive the session, or when the user asks to remember, forget, or consolidate memories. Skip self-contained tasks and facts already authoritative in the current workspace.

Shared long-term memory over MCP.

Recall this repository's OwnMem local memory before changing code, and keep it healthy.
