remember

remember is a skill for Claude Code, Codex from M-T-D-N/agentmemory-codex-windows. It costs 52 tokens per session (609 once invoked), scanned A, a copy of remember, Apache-2.0.

A tool for saving insights, decisions, and other project facts in searchable long-term memory. Saved items can include concept tags and related file paths.

In plain words
What is it for?
Use it when someone asks to remember or save something, such as an authentication decision, implementation detail, related concepts, or source files.
Why use it?
It prevents important project knowledge from being lost between sessions and makes it easier to retrieve using specific terms later.

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 3d 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

86% identical to remember — 2 lines 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.

How it starts

The opening of the file, as written. The whole thing — 69 lines — stays where its author put it; the contents beside it link to each section on GitHub.

The user wants to save this to long-term memory: $ARGUMENTS

Quick start

memory_save {
  "project": "my-project",
  "content": "We rotate JWT refresh tokens on every use; the old token is revoked server-side in auth/refresh.ts.",
  "concepts": "jwt-refresh-rotation, token-revocation, auth-flow",
  "files": "src/auth/refresh.ts"
}

Expected output:

Saved memory abc12345 with 3 concepts: jwt-refresh-rotation, token-revocation, auth-flow.

Why

A memory is only as useful as the terms that retrieve it. Tag with specific concepts so a future recall finds it, and preserve the user's own phrasing.

Workflow

  1. Pull the core insight, decision, or fact out of $ARGUMENTS.
  2. Extract 2-5 lowercased concept phrases. Prefer specific over generic (jwt-refresh-rotation beats auth).
  3. Extract referenced file paths (absolute or repo-relative). Empty if none.
  4. Call memory_save with content, concepts (comma-separated string), and files (comma-separated string). In a multi-agent setup pass agentId so the memory lands in the right agent's scope.
  5. Confirm the save and echo the concepts so the user knows the retrieval terms.
  6. To update a fact, save the corrected version outright: near-duplicate content supersedes the old record, which leaves recall but stays in the version chain.

Anti-patterns

WRONG: concepts: "stuff, code, notes" (generic tags nothing can find later).

RIGHT: concepts: "jwt-refresh-rotation, token-revocation" (specific, retrievable).

Checklist

  • Content preserves the user's phrasing, not a paraphrase.
  • Project is the exact registered project, never an inferred sibling path.
  • Concepts are specific, lowercased, 2-5 items.
  • File paths are real references, not guesses.
  • Confirmation echoes the exact concepts tagged.

  • forget: remove a memory you saved by mistake.

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.
