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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00004 | $0.01518 |
| Opus 5 | $0.00002 | $0.00759 |
| Sonnet 5 | $0.00001 | $0.00304 |
| Haiku 4.5 | $0.00000 | $0.00152 |
Grade A, and why
retrieval-practice 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 11d 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.

retrieval-practice
Guide-type skill for generating retrieval practice materials that make learners reconstruct knowledge from memory. Use it to create teacher-facing or facilitator-facing active-recall questions, low-stakes quizzes, answer notes, misconception checks, and short implementation scripts.
This skill is not a homework tutor, exam writer, study planner, or grading engine. It creates practice materials; it does not run a live quiz one question at a time, manage learner progress, or produce high-stakes assessments.
When to use
Use this skill when the user asks for:
- Retrieval practice questions for a topic, unit, lesson, or concept.
- Classroom starters, exit tickets, recap questions, or low-stakes quizzes.
- Active-recall prompts that avoid passive review and surface misconceptions.
- A mix of free recall, cued recall, recognition, error-correction, diagram, scenario, or explanation prompts.
- Answer notes and teacher implementation guidance.
Do not use this skill for:
- One-on-one homework help or answer checking. Use a homework/quiz tutoring workflow instead.
- Long-term study scheduling. Use a study-planning workflow instead.
- Formal exam papers, graded assessments, or official certification tests.
- Direct-submit assignments or academic dishonesty.
- Generic worksheet generation that only asks recognition or copy-from-notes questions.
How to call
-
Collect the required inputs:
- Topic or concept.
- Learner level and prior knowledge.
- Question count.
- Context of use: starter, exit ticket, homework review, quiz, mixed-topic review, or spaced review.
-
Ask for missing inputs only when they materially affect the question design. If the user gives only a topic, assume a short mixed-ability set and state the assumption.
-
Collect optional inputs when available:
- Time since learning.
- Known misconceptions.
- Curriculum standard or syllabus.
- Allowed question formats.
- Language support needs.
- Whether the user wants answer notes, implementation script, or follow-up variants.
What ships with it

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.

retrieval-practice is a skill published in the GitHub repository Orkas-AI/Orkas-Awesome-AgentSkills (13 stars, last pushed 2mo ago), licensed MIT. It adds 4 tokens to every session and 1,518 once invoked, about $0.0000 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 2026-08-30.
