remember

A command for saving a fact, decision, preference, convention, or lesson directly into Mem0, a service that stores project memories. It records the user's wording and classifies the memory.

In plain words
What is it for?
Use it to save project decisions, coding conventions, things that do not work, personal preferences, setup details, or lessons learned.
Why use it?
It keeps important knowledge available in later coding sessions without relying on the agent to infer it. Explicitly supplied information is stored as stated.

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.

Made for: Claude Code, Codex.

Per session 37 Skills are progressive disclosure: only the name and description are preloaded; the body loads when the skill is used.

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

remember 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 today.

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

Remember something for future sessions

Mem0 creates memories from the session automatically — there is no separate write command. When the user asks to remember something:

  1. Restate the fact clearly and completely in your reply, in one or two sentences, including any names, values, or paths it depends on. Your visible reply is what memory extraction reads, so a precise restatement is what gets remembered.
  2. Tell the user it will be saved with this session's memories when the session ends or compacts, and that it will surface in future sessions in this repository (they can check later with /mem0:search).

Do not invent a storage confirmation or a memory ID — creation happens in the background after the session.

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.

remember is a skill published in the GitHub repository mem0ai/mem0 (64,535 stars, last pushed today), licensed Apache-2.0. It adds 37 tokens to every session and 209 once invoked, about $0.0002 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.
