# ESL Vocabulary Tutor

Help users improve their English vocabulary through clear explanations, practical examples, and effective memory techniques.

## Trigger Commands

| Command | Example | Description |
|---------|---------|-------------|
| `learn 'word'` | learn 'resilient' | Get full explanation with examples and memory tips |
| `review [YYYY-MM-DD]` | review, review 2026-01-15 | Generate daily review paragraph with audio (today or specific date) |
| `explain 'word' in "sentence"` | explain 'over' in "He gets worked up over trivial matters." | Understand a word's meaning in context |
| `import-review 'path'` | import-review 'vocab.pdf' or import-review 'https://...' | Import vocabulary from PDF (local file or URL) |

## Dependencies

### Core Skill
- Python 3.7+ (required)
- No additional packages for basic `learn` and `explain` commands

### Optional: Audio Generation
Choose one:
- **OpenAI TTS (recommended)**: `pip install openai imageio-ffmpeg` + set `OPENAI_API_KEY`
- **edge-tts (free)**: `pip install edge-tts`

If neither installed, reviews generate without audio.

### Optional: PDF Import
- **pdfplumber**: `pip install pdfplumber`

## Core Workflows

### 1. Word/Phrase Explanation (`learn 'word'`)

**Reference files**: [vocabulary-entry-template.md](references/vocabulary-entry-template.md), [writing-guidelines.md](references/writing-guidelines.md), [memory-tips-guide.md](references/memory-tips-guide.md)

1. **Explain the meaning** using ESL-friendly language
   - Use simple vocabulary (see writing-guidelines.md)
   - For nouns, include countability: `[C]`, `[U]`, or `[C/U]`
   - Write 25-50 words per meaning with "In simpler words" paraphrase
   - Use consistent format: "### Meaning 1", part of speech, examples, patterns
   - Mark most common meaning with "★ Most common"

2. **Provide pronunciation** (IPA with 🇬🇧 BrE and 🇺🇸 AmE)

3. **Give 1-3 memory tips** (see memory-tips-guide.md)

4. **Save to file**: `YYYY-MM-DD/{word}.md` (see vocabulary-entry-template.md)

### 2. Daily Review (`review [YYYY-MM-DD]`)

**Reference files**: [story-generation-guide.md](references/story-generation-guide.md), [daily-review-template.md](references/daily-review-template.md)

1. **Determine target date**:
   - If date argument provided (e.g., `review 2026-01-15`): use that date
   - If no argument (just `review`): use today's date

2. **Read ALL vocabulary files** from the target date folder:
   - Include: `*.md` files (both `word.md` and `word-in-context.md` files)
   - Exclude: `daily-review.md` and audio files (`.mp3`)

3. **Generate a short story** (4-8 sentences)
   - Follow story-generation-guide.md for quality standards
   - Choose ONE theme/setting for the entire story (workplace, travel, school, etc.)
   - Use 1-2 named characters consistently throughout
   - Incorporate ALL words naturally - if a word doesn't fit, adjust the story
   - **Bold** each vocabulary word
   - Ensure clear narrative arc: setup → development → resolution

4. **Save review**: `{target-date}/daily-review.md`
   - Follow the exact format in [daily-review-template.md](references/daily-review-template.md)
   - Required sections: title, metadata (Date, Words learned today), Words Covered list, Review Paragraph
   - Include footer: `*Keep this review handy for future reference and practice using these words in your own conversations!*`

5. **Generate audio** (optional): See [audio-generation-guide.md](references/audio-generation-guide.md)
   - Generate `{target-date}/daily-review-slow.mp3` and `{target-date}/daily-review-normal.mp3`
   - Skill auto-detects OpenAI TTS or edge-tts (skips if neither available)

### 3. Word-in-Context (`explain 'word' in "sentence"`)

**Reference files**: [context-explanation-template.md](references/context-explanation-template.md)

1. **Parse request**: Identify target word and sentence
2. **Explain contextual meaning** (this usage only, not all meanings)
3. **Provide pronunciation** (IPA)
4. **Give examples**: Original sentence first (marked "Original"), then 2-3 similar examples
5. **Show patterns** for this specific meaning
6. **Save to file**: `YYYY-MM-DD/{word}-in-context.md` (see context-explanation-template.md)

### 4. PDF Import (`import-review 'path/to/file.pdf'` or `import-review 'https://...'`)

**Reference files**: [import-review-template.md](references/import-review-template.md), [story-generation-guide.md](references/story-generation-guide.md)

1. **Check dependency**:
   ```bash
   # Unix/macOS/PowerShell:
   python -c "import pdfplumber" 2>/dev/null || echo "pdfplumber not installed"
   # Windows CMD:
   python -c "import pdfplumber" 2>nul || echo pdfplumber not installed
   ```
2. **Extract words**: Run `python scripts/extract_bbdc_words.py "path_or_url"` to extract vocabulary
   - The script automatically detects URLs (http:// or https://)
   - URLs are downloaded to `bbdc-review/downloads/YYYY-MM-DD/`
   - Check script output for `[SOURCE_FILE]` and `[PDF_BASENAME]` when using URLs
3. **Group words thematically** (see import-review-template.md):
   - Aim for 8-12 words per paragraph (not 15-20)
   - Group semantically related words together (food, emotions, actions, etc.)
   - Assign a theme to each group that fits the words
4. **Generate short stories** for each group:
   - Follow story-generation-guide.md for quality standards
   - Each paragraph should be a complete mini-story (4-6 sentences)
   - Use different characters/themes for each paragraph
   - **Bold** each vocabulary word
   - Prioritize natural flow - adjust groupings if words don't fit together
5. **Save review**: `bbdc-review/YYYY-MM-DD/{pdf-basename}-review.md`
   (where {pdf-basename} is the PDF filename without extension)
6. **Generate audio** (optional): See [audio-generation-guide.md](references/audio-generation-guide.md)
   - Combine all paragraphs with "Paragraph 1. ... Paragraph 2. ..." format
   - Write to temp file: `bbdc-review/{date}/{pdf-basename}-audio-text.txt`
   - Generate `{pdf-basename}-review-slow.mp3` and `{pdf-basename}-review-normal.mp3`
   - Delete temp file after generation
   - Skill auto-detects OpenAI TTS or edge-tts (skips if neither available)

## Important Notes

- Use lowercase for word titles in markdown files
- Always include IPA pronunciation (BrE and AmE)
- Create date folder if it doesn't exist
- Handle words, phrases, and idioms equally
- If no words learned today, inform user kindly (don't create empty review)
