remember

A command for explicitly saving an insight, decision, or lesson to agentmemory, a store the agent can use in later sessions. You provide the text with /remember.

In plain words
What is it for?
Use it to save architecture decisions, coding patterns, bug details, preferences, facts, or workflow notes for future work.
Why use it?
It prevents important project knowledge from being lost between sessions and labels saved information with searchable concepts and related files.

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.

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 2d 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.

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.

Origin

This is a copy

89% identical to remember — 1 line differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Explicitly save an insight, decision, or learning to agentmemory for future sessions. Wraps the memory_save MCP tool.

Usage

/remember [what to remember]

Instructions

  1. Analyze what needs to be remembered — extract the core insight, decision, or fact.
  2. Extract 2-5 searchable concepts (lowercased keyword phrases). Prefer specific terms ("jwt-refresh-rotation" over "auth").
  3. Extract relevant file paths the memory references.
  4. Call memory_save with:
    • project — the exact registered project for the current repository
    • content — full text to remember (preserve user's phrasing)
    • concepts — extracted concept list
    • files — extracted file list (empty array if none)
    • type — choose from: pattern, preference, architecture, bug, workflow, fact
  5. Confirm the save and show the concepts tagged so the user knows retrieval terms.

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.
