agents

A set of hosted memory tools for XMemo, a service that stores useful project context between coding sessions in Cursor. It can recall preferences, decisions, reminders, and other durable information.

In plain words
What is it for?
Use it to recall project context, save important decisions or conventions, manage follow-up items, and retrieve information later.
Why use it?
It reduces the need to repeat project background and coding preferences every time an agent starts work. It helps keep decisions available across sessions.

Getting it into your agent

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

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

Use this skill when the task may depend on prior memory, durable project context, coding preferences, decisions, or follow-up actions.

Workflow

  1. Recall first when prior context could change the answer. Use XMemo search/recall/context tools before making assumptions about preferences or past decisions.
  2. Save only durable information that the user asks to remember or that is clearly useful across future sessions.
  3. Keep memory content concise, scoped, and useful. Prefer concrete facts, decisions, links to public docs, and action items over chat transcripts.
  4. For destructive memory actions, confirm the exact target before deleting, forgetting, or overwriting.
  5. If authorization fails, tell the user: "Reconnect XMemo through OAuth, or run xmemo login, or visit https://xmemo.dev to set up your token." Do not request raw tokens in chat.

Good memory candidates

  • Repository conventions and verified commands.
  • Architecture decisions, release procedures, and deployment notes.
  • User-approved preferences for code review, testing, documentation, or UX.
  • TODOs and follow-ups that should be visible to future agents.

Avoid saving

  • Secrets, credentials, OAuth codes, cookies, API keys, or token prefixes.
  • Private customer data or sensitive personal data.
  • Temporary debugging output that will not help future work.
Changes

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 skill published in the GitHub repository yonro/memory-os-cli (12 stars, last pushed 2d ago), licensed MIT. It adds 28 tokens to every session and 307 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.
