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

memento-flashcards 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 6d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/memento_cards.py, scripts/youtube_quiz.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Memento Flashcards — Spaced-Repetition Flashcard Skill

Overview

Memento gives you a local, file-based flashcard system with spaced-repetition scheduling. Users can chat with their flashcards by answering in free text and having the agent grade the response before scheduling the next review. Use it whenever the user wants to:

  • Remember a fact — turn any statement into a Q/A flashcard
  • Study with spaced repetition — review due cards with adaptive intervals and agent-graded free-text answers
  • Quiz from a YouTube video — fetch a transcript and generate a 5-question quiz
  • Manage decks — organise cards into collections, export/import CSV

All card data lives in a single JSON file. No external API keys are required — you (the agent) generate flashcard content and quiz questions directly.

User-facing response style for Memento Flashcards:

  • Use plain text only. Do not use Markdown formatting in replies to the user.
  • Keep review and quiz feedback brief and neutral. Avoid extra praise, pep, or long explanations.

When to Use

Use this skill when the user wants to:

  • Save facts as flashcards for later review
  • Review due cards with spaced repetition
  • Generate a quiz from a YouTube video transcript
  • Import, export, inspect, or delete flashcard data

Do not use this skill for general Q&A, coding help, or non-memory tasks.

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.
