remember

A save-before-writing check for persistent memories, with short-lived and long-lived storage options.

In plain words
What is it for?
Use it before saving memory files or reviewing memories that should be archived after a date or event.
Why use it?
It reduces the risk of saving guesses or temporary facts as if they were permanent knowledge by requiring evidence, a storage tier, and expiry details.

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.

How it starts

The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.

memory-loop: remember

A wrongly saved memory gets recalled later as if it were fact — that is one of the biggest sources of persistent hallucination. This gate blocks it at the entrance.

The gate (in order, before any write)

  1. State the candidate and its evidence. What exactly would be saved, and how was it verified? An unverified inference is never saved — verify it first or drop it.

  2. Confirm the tier with the user:

    • tier: long — keeps applying indefinitely (identity, policies, infrastructure facts, recurring preferences).
    • tier: short — consumed by a date or an event (schedules, in-flight work, decisions pending).
  3. If short, agree on the expiry:

    • Absolute: expires: YYYY-MM-DD. The expiry sweep archives it on the first session after that date has passed — the expiry day itself is still live (exclusive boundary).
    • Conditional: expires_when: "<event>" (e.g. "after the release ships"). Never auto-archived; you review it manually when the event happens.
  4. Write the memory file in the native format — the usual frontmatter (name, description, metadata) — adding the lifecycle keys under metadata:

    ---
    name: deploy-freeze-january
    description: Deploys are frozen until the audit completes
    metadata:
      type: project
      tier: short
      expires: 2026-02-01
    ---
    
    <the fact>
    
  5. Update the memory index (MEMORY.md in the same directory) with a one-line pointer.

Optional: salience: 1-5 (recall priority) may be added under metadata; memory-loop does not enforce it — it is a hint for your own recall ordering.

Compatibility contract

Files without a tier key are outside the lifecycle — the sweep never touches them. That is the safe default for every memory that existed before this plugin was installed. Never bulk-add tier to old files; tier them one by one, through this gate, as they come up.

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 choiyounggi/groundwork (3 stars, last pushed 2d ago), licensed MIT. It adds 51 tokens to every session and 650 once invoked, about $0.0003 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 2026-08-31.
