All text, titles, headings, paragraphs, and content must be written in {language.upper()}. CHAPTER: {chapterTitle} (Level {chapterLevel}, ID: {chapterId}) GENERATION HINT: {generationHint} **CRITICAL**: The chapter's generationHint above describes what content this chapter should generate. If the generationHint references documents/images/data, then EACH section that generates content for this chapter MUST assign the relevant ContentParts from AVAILABLE CONTENT PARTS below. NOTE: Chapter already has a heading section. Do NOT generate a heading for the chapter title. ## SECTION INDEPENDENCE - Each section is independent and self-contained - One section does NOT have information about another section - Each section must provide its own context and be understandable alone AVAILABLE CONTENT PARTS: {contentPartsIndex} ## CONTENT ASSIGNMENT RULE - CRITICAL If AVAILABLE CONTENT PARTS are listed above, then EVERY section that generates content related to those ContentParts MUST assign them explicitly. **Assignment logic:** - If section generates text content ABOUT a ContentPart → assign "extracted" format ContentPart with appropriate instruction - If section DISPLAYS a ContentPart → assign "object" format ContentPart - If section's generationHint or purpose relates to a ContentPart listed above → it MUST have contentPartIds assigned - If chapter's generationHint references documents/images/data AND section generates content for that chapter → section MUST assign relevant ContentParts - Empty contentPartIds [] are only allowed if section generates content WITHOUT referencing any available ContentParts AND WITHOUT relating to chapter's generationHint ## CONTENT TYPES Available content types for sections: table, bullet_list, heading, paragraph, code_block, image ## ACCEPTED SECTION TYPES FOR THIS FORMAT The document output format ({outputFormat}) accepts only the following section types: {', '.join(acceptedSectionTypes) if acceptedSectionTypes else 'All section types'} **IMPORTANT**: Only create sections with content types from the accepted list above. Do not create sections with types that are not accepted by this format. ## FORMAT-APPROPRIATE SECTION STRUCTURE When determining which sections to create for this chapter, consider the document's output format ({outputFormat}) and ensure sections are structured appropriately for that format: - Different formats have different capabilities and constraints - Structure sections to match what the format can effectively represent - Consider what content types work best for each format - Ensure the section structure aligns with the format's strengths and limitations - Select content types that are well-suited for the target format - **CRITICAL**: Only use section types from the ACCEPTED SECTION TYPES list above useAiCall RULES: - useAiCall: true ONLY if ContentPart Format is "extracted" AND transformation needed - useAiCall: false if Format is "object" or "reference" (direct insertion) - useAiCall: false if Format is "extracted" AND simple "include full text" instruction - useAiCall: true if no ContentPartIds provided (content must be generated from scratch); Sections without ContentParts must have a clear, detailed generationHint explaining what content to generate RETURN JSON: {{ "sections": [ {{ "id": "section_1", "content_type": "paragraph", "contentPartIds": ["extracted_part_1"], "generationHint": "Include full text", "useAiCall": false, "caption": "optional, only for image sections", "elements": [] }} ] }} **MANDATORY CONTENT ASSIGNMENT CHECK:** For each section, verify: 1. Are ContentParts listed in AVAILABLE CONTENT PARTS above? 2. Does this section's generationHint or purpose relate to those ContentParts? 3. If YES to both → section MUST have contentPartIds assigned (cannot be empty []) 4. Assign ContentPart IDs exactly as listed in AVAILABLE CONTENT PARTS above IMAGE SECTIONS: - For image sections, always provide a "caption" field with a descriptive caption for the image.
