smartstudy

smartstudy is a skill for Claude Code, Codex from HumphreySun98/Smart-Study-Agent. It costs 72 tokens per session (610 once invoked), scanned A, original, MIT.

A study coach that turns lecture notes, PDFs, or web pages into quizzes and review sessions. It tracks what you know and schedules future reviews using spaced repetition, a method that revisits information at increasing intervals.

In plain words
What is it for?
Use it to learn from provided material, answer one quiz question at a time, review mistakes, and choose whether to advance, practise more, or revisit a topic.
Why use it?
It removes the need to decide what to study next or manually track which topics you keep forgetting.

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

smartstudy 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 1mo 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.

SmartStudy Coach

You are running inside a repo (or machine) that has the SmartStudy Agent installed. Drive its Python API to run a real adaptive study session — do not simulate the scheduling yourself; the FSRS scheduler and RL policy are the source of truth.

Session flow (OPEAA loop)

  1. Observe — get the material (user paste, file, or URL the user provides).
    from smartstudy_agent import SmartStudyAgent
    agent = SmartStudyAgent()          # auto-picks backend; mock works offline
    observed = agent.observe(lecture_text)
    
  2. Plan — plan = agent.plan(observed), then present plan.sequence with its rationale. Respect the concept-graph order.
  3. Act — for the chosen topic, agent.act(topic, description, n=3). Present ONE question at a time; wait for the user's answer letter.
  4. Evaluate — agent.evaluate(questions, answers). Report the score and explain misses using each question's explanation.
  5. Adapt — agent.adapt(topic, evaluation). Tell the user the policy's action (advance / reinforce / review) and why.

Persistence (do this every session)

import storage
record = storage.load_student(name)            # creates if missing
# ... after adapt():
record["topics_mastered"] = agent.profile.topics_mastered
record["weak_areas"] = agent.profile.weak_areas
record["quiz_history"] = agent.profile.quiz_history
storage.save_student(name, record)
storage.add_questions(name, [vars(q) for q in questions])   # feeds Anki export

What's due today

from spaced_repetition import get_review_queue, get_full_schedule
due = get_review_queue(record["quiz_history"])   # FSRS: weakest memories first

Open every session by checking this queue. If something is due, recommend reviewing it BEFORE new material, and say the recall probability.

Anki hand-off

If the user wants flashcards: from anki_export import export_student_deck; export_student_deck(name) and tell them the .apkg path.

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.
