**Core Requirements:**

1. **Title Constraints (Optimized for Sidebar Display):**

   - **Character-based limits** (not word-based, as character count determines visual width):
     - **For English titles: Maximum 24 characters**
     - **For character-based languages (Chinese, Japanese, etc.): Maximum 12 characters** (half of English limit)
   - **Purpose**: These limits are specifically designed for sidebar navigation display to prevent crowding and improve readability
   - **Why character count, not word count**:
     - Character width is what determines visual space in sidebar navigation
     - English words vary greatly in length (e.g., "API" = 3 chars, "Configuration" = 13 chars)
     - Character count provides more accurate control over sidebar display width
     - Ensures consistent visual width across different languages
   - Must capture the core concept
   - Use concise, clear terminology
   - Preserve key technical terms or proper nouns when essential
   - Remove unnecessary articles (a, an, the) and filler words
   - Keep titles scannable and user-friendly
   - Optimize specifically for sidebar navigation display

2. **General Guidelines:**

   - Maintain consistency in terminology across all items
   - Prioritize clarity over brevity when there's a conflict
   - Keep technical accuracy intact
   - Preserve brand names, product names, and critical keywords
   - Use title case for document titles
   - Consider the document's context and hierarchy when streamlining
   - Focus on making titles easy to scan in a sidebar navigation menu

**Optimization Strategies:**

- Replace long phrases with shorter equivalents
- Use common abbreviations when widely understood
- Remove redundant modifiers
- Combine related concepts when possible
- Focus on the most important information
- Remove unnecessary words that don't add meaning

**Important Notes:**

- Only streamline the title, descriptions are not modified
- **Sidebar Display Consideration**: Character-based limits (24 for English, 12 for other languages) are specifically chosen to optimize sidebar navigation display
  - Sidebar navigation typically has limited horizontal space
  - Character count determines visual width, not word count
  - English: 24 characters ≈ 4-5 average words, fits standard sidebar width (250-300px)
  - Character-based languages: 12 characters ≈ same visual width as 24 English characters
  - Shorter titles prevent text wrapping and improve visual scanning
  - These limits ensure titles remain readable and don't crowd the navigation menu
- The goal is to make sidebar navigation less crowded and more readable
- Titles should be immediately understandable without reading the full description
- **Language detection**: Determine the primary language of the title and apply the appropriate character limit

<output_rules>

Return a JSON object with:

- `documentList`: array of streamlined document items, each containing:
  - `path`: the same path from input (for mapping purposes)
  - `title`: shortened title (maximum 24 characters for English, 12 characters for character-based languages, optimized for sidebar display)

Ensure each streamlined item:
- Preserves the exact `path` value from the corresponding input item
- Maintains the original intent and meaning
- Uses clear, scannable language
- Fits within the word/character count constraints
- Provides enough context for users to understand the document's purpose at a glance
- Is optimized for sidebar navigation display
