It is intended for agent-assisted tutoring workflows where local study state and reminder behavior are acceptable.\n\n### Deployment Geography for Use:\n\nGlobal\n\n## Known Risks and Mitigations:\n\nRisk: The skill can create persistent daily and weekly reminder behavior and may infer messaging targets from session metadata.\n\nMitigation: Review reminder setup before installation, confirm the target channel, and disable or remove reminders if persistent notifications are not acceptable.\n\nRisk: The skill stores study progress and learning state under ~/learn.\n\nMitigation: Use the skill only where local storage of learning topics, progress, profiles, and review history is acceptable; review or delete that directory as needed.\n\nRisk: The tutoring workflow uses web search for question generation and fact-checking.\n\nMitigation: Avoid submitting sensitive, confidential, or regulated study material to search-backed tutoring steps, or redact it before use.\n\n## Reference(s):\n\n- [ClawHub Skill Page](https://clawhub.ai/kaixiad/skills/retaincraft)\n- [Full workflow](artifact/references/full-workflow.md)\n- [Scenario library](artifact/scripts/scenarios.md)\n- [Academic citations and effect sizes](artifact/scripts/evidence.md)\n- [Output templates](artifact/scripts/templates.md)\n- [Learning templates data](artifact/learning-templates.json)\n- [Donoghue and Hattie "},{"kind":"example","language":"text","snippet":"File v1.4.4:learning-templates.json\n\n{\r\n  \"templates\": [\r\n    {\r\n      \"name\": \"编程语言\",\r\n      \"approach\": \"语法基础 → 小项目巩固 → 逐步增加复杂度\",\r\n      \"interleaving_strategy\": \"混合不同概念（如条件+循环+函数）\",\r\n      \"feynman_prompt\": \"用简单的比喻解释给非程序员听\"\r\n    },\r\n    {\r\n      \"name\": \"外语学习\",\r\n      \"approach\": \"词汇+语法并行 → 阅读巩固 → 输出强化\",\r\n      \"interleaving_strategy\": \"混合听说读写\",\r\n      \"feynman_prompt\": \"用目标语言解释，然后用母语验证\"\r\n    },\r\n    {\r\n      \"name\": \"考试复习\",\r\n      \"approach\": \"知识点梳理 → 真题练习 → 薄弱点强化\",\r\n      \"interleaving_strategy\": \"混合不同科目\",\r\n      \"feynman_prompt\": \"用自己的话解释这个考点\"\r\n    }\r\n  ]\r\n}\n\nArchive v1.4.3: 8 files, 66974 bytes\n\nFiles: learning-templates.json (793b), references/full-workflow.md (27562b), scripts/evidence.md (23606b), scripts/scenarios.md (8523b), scripts/srs.py (106424b), scripts/templates.md (3740b), SKILL.md (20031b), _meta.json (130b)\n\nFile v1.4.3:SKILL.md\n\n---\r\nname: retaincraft\r\ndescription: >\r\n  Spaced repetition & FSRS-5 AI learning assistant with active recall, Feynman technique, interleaved practice, causal questioning.\r\n  间隔重复FSRS-5 AI学习助手，整合主动回忆、费曼学习法、交错练习、因果追问。\r\n  Evidence-based: distributed practice d=0.85, practice testing d=0.74, AI tutoring 0.63-1.3 SD.\r\n  Multi-platform compatible: OpenClaw, WorkBuddy, Claude Code, Hermes Agent.\r\n  Features: FSRS-5 spaced repetition (default), SM-2 fallback, forgetting curve, burnout detection, learning contract, weekly report.\r\n  169 tests, 24 CLI commands, 14 academic citations, zero external dependencies.\r\nversion: 1.4.0\r\nauthor: kaixiad\r\nlicense: MIT\r\nhomepage: https://github.com/kaixiad/RetainCraft\r\ntags:\r\n  - learning\r\n  - education\r\n  - study\r\n  - tutoring\r\n  - ai-tutor\r\n  - ai-learning\r\n  - spaced-repetition\r\n  - active-recall\r\n  - feynman-technique\r\n  - interleaving\r\n  - evidence-based\r\n  - learning-protocol\r\n  - level-system\r\n  - progress-tracking\r\n  - memory\r\n  - review\r\n  - exam\r\n  - study-plan\r\n  - forgetting-curve\r\n  - burnout-detection\r\n  - weekly-report\r\n  - openclaw\r\n  - 学习\r\n  - 教育\r\n  - AI学习\r\n  - AI辅导\r\n  - 间隔"}]}}
