## 概述（中文）

从书籍、播客和日常接触中构建和复习词汇。当用户想要阅读一本书、分享一个新单词、在阅读书籍时询问单词、请求词汇测验、询问单词进度或当 cron/heartbeat 触发预定测验时使用。处理阅读课程、单词收集、三步学习、间隔重复和进度跟踪。

## 原文

# Vocabulary Builder

This skill reads and writes the following files (paths relative to workspace):
- **Vocabulary tracker:** `memory/vocabulary.md` — all word data lives here
- **Audio clips directory:** `docs/tts-fr/` — read-only; user places pronunciation audio files here

Ensure these paths exist or create them before first use.

## Reading Workflow

When the user wants to read/practice reading a book:
1. Ask what book they're reading
2. Check the vocabulary tracker for words from that book — read the END of the Active Words section (use `tail` or read the last entries) to find the actual last word. Note: `memory_search` may return partial/ranked results, so also verify by reading the file directly when checking the latest entry.
3. Tell them the last word added + page number so they know where to continue
4. Ask if they want to: practice pending words, or keep reading and add new ones

## Adding New Words

When the user gives a new word:

1. Give **pronunciation** (IPA, American English)
2. Give **meaning** — clear, simple
3. Give **synonyms** — similar words they might know
4. **Add to tracker immediately** unless the user says not to add it
5. **Show the word card** after adding

If the user says they are focusing on **pronunciation**, ask which words they confuse (for example: seem / same / sim). In pronunciation-focused mode:
- Treat the set as a **single comparison entry** if the user's goal is sound comparison, not three separate vocabulary items
- Show **each word's pronunciation separately** in the reply and in the word card
- Record the entry with a combined title like `### seem / same / sim`
- Use the **Meaning** field to explain **how to pronounce the words and what sound difference to notice**, not the usual vocabulary meaning
- Keep the pronunciation explanation short, practical, and contrast-focused
- If the user does not provide a sentence, generate **very very simple context lines** for each word
- Use the shared book/page/context the user gives

Add to the `## Active Words` section, at the END (before `---` separator for Long-Term Review).

### Word Entry Format

```markdown
### [word]
- **Type:** noun/verb/adj/adv
- **Learned:** YYYY-MM-DD HH:MM TZ
- **Book:** [source name]
- **Page:** [number]
- **Pronunciation:** /IPA/
- **Meaning:** [explanation]
- **Synonyms:** [similar words]
- **Context:** "[sentence from source]"
- **Practice History:**
  - YYYY-MM-DD HH:MM TZ: Step N ✓/✗ (notes)
```

### Pronunciation Comparison Entry Format

```markdown
### [word 1] / [word 2] / [word 3]
- **Type:** pronunciation comparison set
- **Learned:** YYYY-MM-DD HH:MM TZ
- **Book:** [source name]
- **Page:** [number]
- **Pronunciation:**
  - **[word 1]** — /IPA/
  - **[word 2]** — /IPA/
  - **[word 3]** — /IPA/
- **Meaning:** Short pronunciation guidance explaining the sound difference (for example: `[word 1]` has /iː/, `[word 2]` has /eɪ/, `[word 3]` has /ɪ/)
- **Synonyms:** pronunciation set, minimal comparison set
- **Context:**
  - **[word 1]:** "[very simple sentence]"
  - **[word 2]:** "[very simple sentence]"
  - **[word 3]:** "[very simple sentence]"
- **Practice History:**
```

### French Words

- **Context:** French sentence only
- **English Translation:** Separate field with English translation
- Do NOT mix French and English in the same field
- User places audio clips in `docs/tts-fr/` → add **Audio** field with the file path

## 3-Step Learning Process

Run all 3 steps in one conversation flow (not spread across hours):

- **Step 1:** Show the plain word + review count (e.g. "reviewed 0 times" or "reviewed 3 times") → ask "Do you know the pronunciation?" → user types word to confirm
- **Step 2:** Ask "What does it mean?" → check if correct/close enough
- **Step 3:** Ask user to write a sentence using the word

Trust-based pronunciation — no voice/ASR check. User types word to confirm.

### Pronunciation-Focused Practice

If the user wants pronunciation practice instead of meaning-first vocabulary study:
- Ask which words they confuse
- Show the pronunciation for **each word** clearly
- Highlight the key sound contrast briefly
- Explain **how to say the sounds** (mouth shape, long/short vowel, tongue or lip position when useful) instead of focusing on dictionary meaning
- Record the set as one pronunciation comparison entry when that is more useful than separate entries
- Use **very simple example sentences** in the Context field, one short line per word when possible
- Do not force the normal meaning-first 3-step flow for a pure pronunciation comparison request

## Spaced Repetition Schedule

After completing all 3 steps, review at:
- Next day → 3 days → 1 week → 2 weeks → 1 month → 3 months
- After 3-month review: word is **mastered**

### Word Progression

Words move through three sections in the tracker:
1. **Active Words** — currently learning
2. **Long-Term Review Words** — completed all steps, in spaced review
3. **Mastered Words** — passed all reviews through 3 months

## Quiz Rules

- **One word per quiz** — no rapid-fire
- **No spam:** If no reply to previous quiz today → don't send new one
- **Reset next day:** New day = can send quiz even if yesterday's unanswered
- **Sleep hours:** No messages 11 PM – 7 AM (user's timezone)
- **Priority:** due for review > newer words (incomplete steps) > refresher

### Random Word Selection

1. Count each word's total practice history entries (all steps and reviews combined)
2. Sort all words by review count ascending (least reviewed first)
3. Take the group with the minimum review count
4. Within that group, randomize: count words (N), use `(current_timestamp_ms % N) + 1` to pick position
5. **Never pick the same word twice in a row.** Check Quiz State for the last quizzed word and skip it.

**Always show review count** when quizzing: e.g. "(reviewed 0 times)" or "(reviewed 3 times)".

### On-Demand Quizzes

User can request specific quizzes anytime — these override normal priority and spam rules:

- "Quiz me" → random word
- "Quiz me on [word]" → specific word
- "Quiz me on words from [book]" → random from that book
- "Quiz me on words from this week" → last 7 days
- "Quiz me on [book] page [N] to [M]" → page range
- "Give me 3 quizzes" → run 3 words in a row

On-demand refresher: If no words are due/pending, pick random word from all learned words. Still record quiz date.

## Quiz State Tracking

Keep a `## Quiz State` section at the top of the tracker file:

```markdown
## Quiz State
- **Pending quiz:** [word] ([review type], [step] sent)
- **Last quiz sent:** YYYY-MM-DD HH:MM TZ
```

Update after each quiz interaction.

## Cron Setup

When the user asks to set up a scheduled vocabulary quiz:

1. **Ask for:** frequency (default: every 1h), delivery channel + target
2. **Job name:** `vocabulary-quiz-{agentName}` (e.g. `vocabulary-quiz-english`)
3. **Create a cron job** with these settings:
   - Session: isolated
   - Timeout: 120 seconds
   - Message: instruct the agent to use the `vocabulary-builder` skill to run a quiz
4. **Quiz constraints** (include in the cron message):
   - Check Quiz State — skip if pending quiz unanswered today
   - Respect sleep hours: no messages 11PM–7AM (user's timezone)

## 中文说明

# Vocabulary Builder

此技能读取和写入以下文件（路径相对于工作区）：
- **词汇追踪器：** `memory/vocabulary.md` — 所有单词数据都存放于此
- **音频片段目录：** `docs/tts-fr/` — 只读；用户在此放置发音音频文件

请确保这些路径存在，或在首次使用前创建它们。

## 阅读工作流

当用户想要阅读/练习阅读一本书时：
1. 询问他们正在读什么书
2. 在词汇追踪器中检查该书的单词——读取 Active Words 部分的末尾（使用 `tail` 或读取最后的条目）以找到实际的最后一个单词。注意：`memory_search` 可能返回部分/排序后的结果，因此在检查最新条目时也要通过直接读取文件来验证。
3. 告诉他们最后添加的单词 + 页码，以便他们知道从哪里继续
4. 询问他们想要：练习待复习单词，还是继续阅读并添加新单词

## 添加新单词

当用户给出一个新单词时：

1. 给出**发音**（IPA，美式英语）
2. 给出**含义**——清晰、简单
3. 给出**同义词**——他们可能认识的相似单词
4. **立即添加到追踪器**，除非用户说不要添加
5. 添加后**显示单
