## Available Tools

The D4D GPT-5 Assistant has access to these tools:

### Web Tools
- **WebSearch**: Search the web for dataset documentation and information
- **WebFetch**: Fetch content from URLs

### Literature Tools
- **search_europepmc_papers**: Search Europe PMC for academic papers
- **get_europepmc_paper_by_id**: Get paper metadata by DOI, PMID, or PMCID
- **get_europepmc_full_text**: Get full text of papers when available

**Note**: Use these tools together to gather comprehensive information when creating D4D datasheets. Combine web search and academic literature to extract complete metadata.

## When to Use This Workflow

This workflow is triggered when a user requests creation of a new D4D datasheet, typically through:
- Direct request: "Create a D4D datasheet for [dataset]"
- Providing URLs to dataset documentation
- Providing content with dataset information

## Step-by-Step Process

### 1. Load the D4D Schema

**Schema Reference:**
- The complete schema is at: `src/data_sheets_schema/schema/data_sheets_schema_all.yaml`
- This contains ALL D4D classes, slots, and enums in a single file
- Use this schema as the authoritative reference for structure and valid values

**Key Schema Sections:**
- `id` (required) - Unique identifier for the dataset
- `name` (required) - Dataset name
- `motivation` - Purpose and creation motivation (Motivation class)
- `composition` - What the dataset contains (Composition class)
- `collection_process` - How data was collected (CollectionProcess class)
- `preprocessing` - Cleaning and preprocessing steps (Preprocessing class)
- `uses` - Recommended and unsuitable uses (Uses class)
- `distribution` - How dataset is distributed (Distribution class)
- `maintenance` - Update and maintenance plans (Maintenance class)

### 2. Gather Source Content

**From User Request:**
- User will provide one or more URLs pointing to dataset documentation (webpages, PDFs, etc.)
- Extract URLs from the user's request
- If multiple URLs are provided, assume they describe the SAME dataset

**Fetch Content:**
- Use WebFetch tool for web pages
- For academic papers, use Europe PMC tools
- If content is provided directly, process that content

### 3. Extract Metadata

**Processing Guidelines:**
- Process all source content to identify D4D-relevant information
- Map information to the appropriate D4D schema classes (Dataset, Motivation, Composition, etc.)
- **Only populate fields you are confident about** - leave uncertain fields as `null` or omit them
- Ensure required fields are present (especially `id`, `name` in Dataset class)
- Follow the schema strictly for field names, types, and structure
- Use null values or omit fields for missing information

**Field Population Rules:**
- Required fields: MUST be populated (id, name)
- Optional fields: Only populate if information is explicitly available
- Multivalued fields: Use YAML list syntax when schema specifies `multivalued: true`
- Enum fields: Only use values defined in schema enums
- Dates: Use ISO 8601 format (YYYY-MM-DD)

### 4. Generate Valid YAML

**YAML Structure Requirements:**
- Output must be valid YAML conforming to the D4D schema
- Use proper YAML syntax with correct indentation (2 spaces per level)
- Include `id` and `name` as top-level Dataset fields
- Structure nested objects according to schema class definitions
- Use lists where schema specifies `multivalued: true`
- Follow enum constraints for fields with controlled vocabularies

**Example Structure:**
```yaml
id: example_dataset_001
name: Example Dataset
motivation:
  purpose: |
    Multi-line description of why this dataset was created.
  tasks:
    - Classification
    - Regression
composition:
  instance_description: Description of what each instance represents
  instance_count: 1000
collection_process:
  how_was_data_acquired: Description of acquisition process
  collection_mechanisms: Survey
# ... additional sections ...
```

### 5. Save Location

All D4D datasheets created by the GPT-5 assistant MUST be saved to:
```bash
# Extract dataset name from YAML (use lowercase, replace spaces with underscores)
DATASET_NAME="<dataset_name>"  # e.g., "cm4ai", "ai_readi_voice"

# Save location (REQUIRED - all GPT-5-created D4Ds go here)
OUTPUT_FILE="data/d4d_concatenated/gpt5/${DATASET_NAME}_d4d.yaml"
```

**Why this location:**
- Separates GPT-5-generated datasheets from other methods
- All GPT-5 outputs in one place for easy review and management
- Distinct from Claude Code outputs in `data/d4d_concatenated/claudecode/`

### 6. Validation

**Critical**: Validation MUST pass before finalizing. Do not skip this step.

```bash
# Validate the generated YAML
poetry run linkml-validate -s src/data_sheets_schema/schema/data_sheets_schema_all.yaml \
  -C Dataset ${OUTPUT_FILE}
```

**Understanding Validation Output:**
- **Success**: No output or "✓ Validation passed" message
- **Failure**: Error messages describing schema violations

**Common Validation Errors and Fixes:**

1. **Missing Required Field**
   ```
   Error: 'id' is a required property
   ```
   **Fix**: Add the missing required field (`id` and `name` are always required)

2. **Invalid Enum Value**
   ```
   Error: 'SomeValue' is not one of ['ValidValue1', 'ValidValue2']
   ```
   **Fix**: Check the schema for valid enum values and use one from the allowed list

3. **Wrong Data Type**
   ```
   Error: 'string_value' is not of type 'integer'
   ```
   **Fix**: Convert the value to the correct type (e.g., change "1000" to 1000 for integers)

4. **Invalid YAML Syntax**
   ```
   Error: mapping values are not allowed here
   ```
   **Fix**: Check indentation, quotes, and YAML structure

5. **Unknown Field**
   ```
   Error: Additional properties are not allowed ('unknown_field' was unexpected)
   ```
   **Fix**: Remove the field or check if you're using the correct field name from the schema

**If Validation Fails:**
1. Read the error message carefully to identify the issue
2. Check the schema file to understand correct structure
3. Fix the YAML file
4. Re-run validation
5. Repeat until validation passes
6. **DO NOT finalize with invalid YAML**

### 7. Generate HTML Preview

```bash
# Generate human-readable HTML from the YAML
poetry run python src/html/human_readable_renderer.py ${OUTPUT_FILE}

# This creates <dataset_name>_d4d.html
# Reviewers will use this to preview the datasheet in human-readable format
```

## Output Guidelines

**YAML Generation:**
- Generate ONLY valid YAML conforming to the schema
- Do not include commentary before or after the YAML content
- Ensure all required fields are present
- Use `null` for unknown optional fields (or omit them entirely)
- Validate YAML syntax before finalizing
- If validation fails, fix errors and re-validate

**Communication:**
- Be clear and concise in descriptions
- Provide actionable review instructions
- Highlight what was found vs. what was not found in sources

## Error Handling

**If schema validation fails:**
1. Read the validation error message carefully
2. Identify the problematic field or structure
3. Consult the schema to understand the correct format
4. Fix the error in the YAML
5. Re-validate before proceeding
6. Do NOT finalize with invalid YAML

**If source URLs are inaccessible:**
1. Note which URLs failed
2. Proceed with available sources
3. Mark sections as incomplete if critical information is missing
4. Suggest alternative sources

**If required fields cannot be populated:**
1. DO NOT create the datasheet if `id` or `name` cannot be determined
2. Request clarification from user
3. Ask user to provide missing required information
4. Wait for response before proceeding

## Important Reminders

- Always validate before finalizing
- Generate HTML preview for reviewer convenience
- Only populate fields with confident information
- Follow null/empty value handling patterns (see CLAUDE.md)
- Use schema enums for controlled vocabulary fields
