⚠️ Execution Checklist (执行清单)

All commands use paths relative to this SKILL.md's directory. 以下所有命令路径相对于本文件所在目录。

Must read before each learning session (每次学习开始前必须读)

Critical Steps (关键执行步骤 - 不可违反)

1. Must execute after module test (模块测试结束后必须执行):

   python3 scripts/srs.py record-test <topic> <total> <correct>
   

   Not executing = module test invalid, level not updated. 不执行此命令 = 模块测试无效，等级不更新。

2. Feynman Check - L5 required (费曼检验 - L5 必需):

   • L5 mastery requires: 2 consecutive module tests >=90% + Feynman check passed
   • L5 精通需要：连续 2 次模块测试答对率 >=90% + 费曼检验通过
   • AI plays "confused student", asks 3 questions
   • AI 助手扮演"不懂的学生"，追问 3 个问题

3. Scoring Discipline (评分纪律 - 不可违反):

   • Scoring criteria announced before test, cannot change during test
   • 评分标准在测试开始前公布，测试过程中不可修改
   • Single question score >=7 = "correct"
   • 单题得分 >=7 分 = 算"答对"

4. Level-up Restrictions (逐级升级限制):

   • Levels can only increase one at a time, no skipping
   • 等级只能逐级升级，不能跳级
   • Each upgrade requires 2 consecutive passes
   • 每次升级需要连续 2 次达标

5. Ensure learning reminder is active (确保学习提醒已生效):

   • Check if a timed learning reminder exists for this user
   • If yes → continue normally
   • If no → trigger Step 0.1 reminder creation flow AI MUST verify reminder status before proceeding. Missing reminder = learning risk. AI 必须确认提醒状态再继续。无提醒 = 学习中断风险。

6. Manual reminder if not received (未收到提醒可手动执行):

   python3 scripts/srs.py reminder
   

7. Check reminder status (检查提醒状态):

   • OpenClaw: python3 scripts/srs.py check-reminder
   • Other platforms: Verify using your platform's native mechanism (see Step 0.1 "Reminder check at session start")

8. Switch reminder channel (切换提醒渠道 — OpenClaw only):

   python3 scripts/srs.py switch-channel

🔄 Complete Workflow: Five Steps (完整流程：五步启动)

Step 0: Learning Assessment (学习意愿评估)

• User completes self-assessment questionnaire (主题、目标、水平、时间、偏好)
• 用户完成自我评估问卷

Step 0.1: Learning Contract (学习契约)

• Trigger: After Step 0, before Step 1
• 触发时机：Step 0 完成后，Step 1 之前
• AI generates a learning plan based on assessment
• AI 助手根据评估生成学习计划
• User can confirm, modify, or skip
• 用户可以确认、修改或跳过

Output format (输出格式):

📅 学习时间
- 每周学习天数：周一到周五（5 天）
- 每天学习时间：晚上 8:00 - 9:00（1 小时）
- 休息日：周六、周日（轻量复习）

📚 学习节奏
- 每个模块预计：3-5 天
- 每天新概念：2-3 个
- 每天复习：根据间隔重复算法（SM-2/FSRS-5）到期情况

🎯 目标
- 目标等级：L4 熟练
- 预计总时长：30 小时
- 预计完成日期：2026-06-15

请确认以上计划，或告诉我需要调整的地方。
你可以：
1. 输入"确认"接受计划
2. 输入"修改"调整学习时间
3. 输入"跳过"使用默认设置

Estimated duration formula (预计时长公式):

预计总时长 = 模块数 × 每模块平均Phase数 × 每Phase平均时长
预计完成日期 = 当前日期 + 预计总时长 / (每日学习时长 × 每周学习天数)

Scientific basis (科学依据): Gollwitzer (1999) - Implementation intentions. Specific plans increase execution rate by d=0.65.

Reminder creation (提醒创建): After user confirms the learning contract, AI MUST create a timed reminder:

1. Extract learning time from the contract (e.g., "每天 20:00")
2. OpenClaw: Run python3 scripts/srs.py setup-reminder (auto-detects channel + delivery target)
3. Other platforms: Create a reminder using your platform's native mechanism, then tell the user the schedule
4. Tell user: "提醒已设置，每天 XX:XX 会提醒你学习"
5. If creation fails → tell user the fallback plan

Reminder check at session start (会话开始时提醒检查): Every time a learning session starts, check if the user has a timed reminder.

• If yes → continue normally
• If no → create one (time from learning plan, message: "该复习了！")

Step 0.5: Pre-study Materials (预习材料 - 零基础专用)

• Trigger: user self-assesses as "complete beginner"
• 触发条件：用户自评"完全零基础"
• AI searches beginner materials, creates "quick overview" (800-1500 words)
• AI 助手搜索入门资料，精炼成"快速概览"

Step 1: Diagnostic Test (摸底考试)

• 5-8 questions, covering basics to advanced
• 5-8 道题，覆盖基础到进阶
• ⚠️ Diagnostic test does NOT call record-test, NOT written to test_history
• ⚠️ 摸底考试不调用 record-test，不写入 test_history

Step 2: Learning Path Customization (学习路径定制)

• Step 2a: Industry research (web_search learning routes, job requirements)
• Step 2a：行业调研（web_search 搜索学习路线、岗位要求）
• Step 2b: Path generation (3-8 modules with goals, knowledge points, acceptance criteria)
• Step 2b：路径生成（3-8 个模块，含目标、知识点、验收标准）
• Step 2c: User confirmation before starting
• Step 2c：用户确认后开始学习

Step 3-4: Learning Loop + Spaced Repetition (学习循环 + 间隔复习)

• See references/full-workflow.md
• 详见 references/full-workflow.md

📊 Level System L1-L5 (等级系统)

Level (等级)	Standard (标准)	Behavior (行为特征)
🔴 L1 Entry (入门)	No test history or first <20%	Start from zero (从零开始)
🟠 L2 Beginner (初学)	First >=20%	Has concepts but not systematic (有概念但不系统)
🟡 L3 Intermediate (进阶)	2 consecutive >=40%	Can apply independently (能独立应用)
🟢 L4 Proficient (熟练)	2 consecutive >=70%	Can solve complex problems (能解决复杂问题)
🔵 L5 Mastery (精通)	2 consecutive >=90% + Feynman check	Can teach others (能教会别人)

Promotion/Demotion Rules (升降级规则)

• Promotion: 2 consecutive passes (升级：连续 2 次达标)
• Demotion: 3 consecutive failures, one level per check, min L2 (降级：连续 3 次不达标，每次只降一级，最低 L2)
• Gradual degradation: knowledge fades continuously, not in steps (渐进衰减：知识连续衰减，非阶梯式)

Two Independent Dimensions (两个独立维度)

• Level (等级) = Based on module test accuracy (权威)
• Review Status (复习状态) = Based on concept mastery ratio (仅展示)

---

🔄 Learning Loop Per Module (学习循环 - 每模块)

Phase 0: Framework Building (框架搭建 - 10-15 min)

• AI asks questions, guides discovery of core concepts
• AI 助手提问，引导发现核心概念

Phase 1: Active Input (主动输入 - 25-40 min)

• User studies materials, pause to recall every 15 min
• 用户学习原始材料，每 15 分钟暂停回忆

Phase 2: Feynman Check (费曼检验 - 15-20 min)

• User explains to AI, AI plays "confused student"
• 用户向 AI 解释所学，AI 扮演"不懂的学生"追问
• Scoring: 3 questions × 10 pts (Accuracy 4 + Depth 3 + Examples 3)
• Each ≥7 pts = pass; all 3 must pass (与模块测试评分规则一致)

Phase 2.5: Simulation (实战模拟 - 15-20 min)

• Recommend 2-3 scenarios, user chooses, execute 3-5 rounds
• 推荐 2-3 个模拟场景，用户选择后执行 3-5 轮
• Score by 5 dimensions (100 points), see scripts/scenarios.md
• 按 5 维度打分（100分），见 scripts/scenarios.md

Phase 3: Test & Reinforce (测试巩固 - 15-20 min)

• 5-8 mixed question types
• 5-8 道混合题型测试
• ⚠️ Must determine "review" or "module test"
• ⚠️ 必须判定"复习"还是"模块测试"

Item (项目)	Review (复习)	Module Test (模块测试)
Purpose (目的)	Strengthen memory (强化记忆)	Phase assessment (阶段性评估)
Impact (影响)	No level change (不影响等级)	Determines level (决定等级升降)
Command (命令)	srs.py rate	srs.py record-test

Decision rule (判定规则):

• First completion of a module → Module Test (record-test)
• Retest after fixing weak areas → Module Test (record-test)
• Daily review / spaced repetition due → Review (rate)
• Rule of thumb: If the result could change the user's level → Module Test. Otherwise → Review.

Phase 4: Spaced Repetition (间隔复习 - SM-2/FSRS-5)

• Based on spaced repetition schedule (SM-2 or FSRS-5, configurable), proactive reminders when due
• 基于间隔重复时间表（SM-2 或 FSRS-5，可配置），到期主动提醒
• Heartbeat check: python3 scripts/srs.py due
• 心跳检查：python3 scripts/srs.py due

---

⚠️ Burnout Detection (倦怠检测)

Triggers (触发条件 - 任一):

• 3+ consecutive wrong answers (连续答错 3 题以上)
• 2 consecutive score drops (连续 2 次测试分数下降)
• User says "tired" / "too hard" (用户主动说"累了""太难了")

Response (响应): Lower difficulty, suggest break, switch to easy mode 响应：降低难度、建议休息、切换轻松模式

---

🤖 AI Assistant Behavior (AI 助手行为规范)

✅ Should Do (应该做的)

• User asks question → First ask "what do you think?"
• 用户问问题 → 先反问"你是怎么想的？"
• User stuck → Give hints (not answer)
• 用户卡住 → 给提示（不是答案）
• Before answering knowledge questions → web_search first
• 每次回答知识性问题前 → 先 web_search 验证
• Level changes must inform user immediately
• 等级变化时必须主动告知用户

❌ Should Not Do (不应该做的)

• Give complete answer directly (除非用户明确要求)
• Only score without explanation after test (测试后只打分不解析)

---

🔍 Search-First Rules (搜索优先规则)

Iron rule: AI must search before answering any knowledge question 铁律：AI 助手回答任何知识性问题前，必须先搜索验证

Scenario (场景)	Must Search? (必须搜索?)
User asks "what is XX" (用户问"XX 是什么")	✅
Correct answer for test (出测试题的正确答案)	✅
Feynman check judgment (费曼检验时判断对错)	✅
Planning learning path (规划学习路径)	✅
Basic common knowledge (基础常识)	❌
Flow conversation (流程性对话)	❌

Rule (规则): Factual statements must include source links 规则：事实性陈述必须附来源链接

---

🔒 Session Checkpoint (会话检查点)

Phase Completion Checklist (Phase 完成自检)

□ Current phase core output completed? (当前 Phase 核心产出已完成?)
□ If module test: record-test called? (如果模块测试：已调用 record-test?)
□ Key progress written to session notes? (关键进展已写入会话笔记?)

Check Commands (检测命令)

python3 scripts/srs.py check-session [topic]  # Check unrecorded tests
python3 scripts/srs.py check-burnout <topic>   # Analyze burnout risk

---

🧠 Memory Persistence (记忆持久化)

Dual System (双系统)

System (系统)	Stores (存什么)	Location (位置)
Platform notes (平台笔记)	Progress summary, weak points (进度摘要、薄弱点)	Use your platform's native notes/memory
~/learn/	SRS data, concept mastery (间隔重复数据、概念掌握度)	~/learn/topics/{topic}/concepts.json

Recovery Priority (恢复优先级)

concepts.json > session notes (concepts.json > 笔记)

The critical data is in concepts.json. Session notes are supplementary — use any storage mechanism your platform provides. 关键数据在 concepts.json。会话笔记是辅助性的——用你平台自带的任何存储方式。

---

💓 Review Reminders (复习提醒 - Heartbeat)

AI receives heartbeat → python3 scripts/srs.py due → Has due content → Notify user
AI 助手收到心跳 → python3 scripts/srs.py due → 有到期内容 → 通知用户

Delivery (投递): When sending reminders, use your platform's native messaging to the user's active channel. Do not rely on implicit target resolution. 发送提醒时：使用你平台的原生消息机制发送到用户的活跃渠道。不要依赖隐式目标解析。

🧬 Personalized Parameters (个性化参数优化)

FSRS-5 支持个性化参数优化，让算法适应每个用户的记忆特征。

python3 srs.py optimize-params

前置条件：

• 需要 1,000+ 条 review 记录（FSRS 社区经验：低于此会过拟合）
• 需要多样化的 rating 分布（>95% 相同 rating = 无效信号）
• 建议每 2-3 个月优化一次，不要频繁优化

优化过程：

• 使用数值梯度下降（有限差分）最小化 BCE 损失
• 优化 w[0]-w[14]（15/19 个参数）
• 跳过 w[15]-w[18]（hard/easy 系数 + 短期学习参数，数据不足）
• 结果保存到 config.json 的 fsrs_weights 字段

何时触发：

• 当用户积累了足够 review 数据时，AI 应主动建议运行 optimize-params
• 新参数需要 2 周观察期才能评估效果
