# Document Sharding Task

## Purpose

- Split a large document into multiple smaller documents based on level 2 sections
- Create a folder structure to organize the sharded documents
- Maintain all content integrity including code blocks, diagrams, and markdown formatting

## Task Instructions

1. Identify Document and Target Location

- Determine which document to shard (user-provided path)
- Create a new folder under `docs/` with the same name as the document (without extension)
- Example: `docs/prd.md` → create folder `docs/prd/`

2. Parse and Extract Sections

CRITICAL AEGNT SHARDING RULES:

1. Read the entire document content
2. Identify all level 2 sections (## headings)
3. For each level 2 section:
   - Extract the section heading and ALL content until the next level 2 section
   - Include all subsections, code blocks, diagrams, lists, tables, etc.
   - Be extremely careful with:
     - Fenced code blocks (```) - ensure you capture the full block including closing backticks and account for potential misleading level 2's that are actually part of a fenced section example
     - Mermaid diagrams - preserve the complete diagram syntax
     - Nested markdown elements
     - Multi-line content that might contain ## inside code blocks

CRITICAL: Use proper parsing that understands markdown context. A ## inside a code block is NOT a section header.]]

### 3. Create Individual Files

For each extracted section:

1. **Generate filename**: Convert the section heading to lowercase-dash-case
   - Remove special characters
   - Replace spaces with dashes
   - Example: "## Tech Stack" → `tech-stack.md`

2. **Adjust heading levels**:
   - The level 2 heading becomes level 1 (# instead of ##) in the sharded new document
   - All subsection levels decrease by 1:

   ```txt
     - ### → ##
     - #### → ###
     - ##### → ####
     - etc.
   ```

3. **Write content**: Save the adjusted content to the new file

### 4. Create Index File

Create an `index.md` file in the sharded folder that:

1. Contains the original level 1 heading and any content before the first level 2 section
2. Lists all the sharded files with links:

```markdown
# Original Document Title

[Original introduction content if any]

## Sections

- [Section Name 1](./section-name-1.md)
- [Section Name 2](./section-name-2.md)
- [Section Name 3](./section-name-3.md)
  ...
```

### 5. Preserve Special Content

1. **Code blocks**: Must capture complete blocks including:

   ```language
   content
   ```

2. **Mermaid diagrams**: Preserve complete syntax:

   ```mermaid
   graph TD
   ...
   ```

3. **Tables**: Maintain proper markdown table formatting

4. **Lists**: Preserve indentation and nesting

5. **Inline code**: Preserve backticks

6. **Links and references**: Keep all markdown links intact

7. **Template markup**: If documents contain {{placeholders}} ,preserve exactly

### 6. Validation

After sharding:

1. Verify all sections were extracted
2. Check that no content was lost
3. Ensure heading levels were properly adjusted
4. Confirm all files were created successfully

### 7. Report Results

Provide a summary:

```text
Document sharded successfully:
- Source: [original document path]
- Destination: docs/[folder-name]/
- Files created: [count]
- Sections:
  - section-name-1.md: "Section Title 1"
  - section-name-2.md: "Section Title 2"
  ...
```

## Important Notes

- Never modify the actual content, only adjust heading levels
- Preserve ALL formatting, including whitespace where significant
- Handle edge cases like sections with code blocks containing ## symbols
- Ensure the sharding is reversible (could reconstruct the original from shards)
