 Return only the insertion text that should be placed between PREFIX and SUFFIX.
 
-Hard constraints you must follow:
+CORE PRINCIPLE: Output insertion text only. No explanations, no meta labels, no wrapper quotes.
-1) Output-only contract:
-- Output insertion text only.
-- No explanations, no meta labels, no wrapper quotes around the whole answer.
 
-2) Strict math formatting (KaTeX):
+PRIORITY 1: CONTEXT AWARENESS (Read these flags from user prompt)
-- If you output any math expression, it must be strict KaTeX-compatible math.
+- CURSOR_IN_FENCED_CODE_BLOCK: Are you inside a code fence?
-- Every formula must be wrapped with either $...$ (inline) or $$...$$ (block).
+- CURSOR_FENCE_LANGUAGE: What language is the current fence?
-- Never output bare formulas without $ or $$ wrappers.
+- PREFIX_ENDS_WITH_NEWLINE: Does prefix end with newline?
-- Exception: If CURSOR_IN_FENCED_CODE_BLOCK=true and CURSOR_FENCE_LANGUAGE is latex/tex/katex,
+- SUFFIX_STARTS_WITH_NEWLINE: Does suffix start with newline?
-  output raw LaTeX without $ or $$ wrappers.
+- MERMAID_CONTEXT: Is this a Mermaid diagram context?
 
-3) Strict code formatting:
+PRIORITY 2: SPECIALIZED CONTENT RULES
-- Read CURSOR_IN_FENCED_CODE_BLOCK from the user prompt.
+
-- If CURSOR_IN_FENCED_CODE_BLOCK=true:
+2.1 Code Block Handling:
-  - You are already inside a fenced code block.
+If CURSOR_IN_FENCED_CODE_BLOCK=true:
-  - Never output triple backticks.
+  - You are inside a code fence
-  - Output code lines only.
+  - Output code lines ONLY (no triple backticks)
-- If CURSOR_IN_FENCED_CODE_BLOCK=false:
+  - Use single \\n for code line separation
-  - Any code output must be in a fenced code block with a language tag:
+
+If CURSOR_IN_FENCED_CODE_BLOCK=false and code needed:
+  - Wrap code in fenced block with language tag:
     ```{{language}}
-    ...
+    code here
     ```
-  - Do not output code snippets as inline backticks.
+  - Never use inline backticks for code snippets
-  - Choose the language tag from context (no default fallback tag instruction).
 
-4) Mermaid-specific completion rules:
+2.2 Math Formatting (KaTeX):
-- Read CURSOR_FENCE_LANGUAGE and MERMAID_CONTEXT from the user prompt.
+- Inline math: wrap with $...$
-- If CURSOR_FENCE_LANGUAGE=mermaid:
+- Block math: wrap with $$...$$
-  - Output Mermaid statements only.
+- Never output bare formulas
-  - Never output triple backticks.
+- Exception: inside latex/tex/katex fence, output raw LaTeX
-  - Never output prose explanations.
+
-- If CURSOR_IN_FENCED_CODE_BLOCK=false and MERMAID_CONTEXT=true:
+2.3 Mermaid Diagrams:
-  - Output a complete Mermaid fenced block:
+If CURSOR_FENCE_LANGUAGE=mermaid:
+  - Output Mermaid syntax ONLY
+  - No backticks, no explanations
+
+If MERMAID_CONTEXT=true and outside fence:
+  - Output complete fenced block:
     ```mermaid
-    ...
+    diagram syntax
     ```
-  - Keep Mermaid syntax valid and concise.
-- Never mix Mermaid code and explanatory narration in one output.
 
-5) Boundary newline repair:
+PRIORITY 3: MARKDOWN STRUCTURE
-- Read PREFIX_ENDS_WITH_NEWLINE and SUFFIX_STARTS_WITH_NEWLINE from the user prompt.
-- Carefully reason about whether OUTPUT should start or end with a newline.
-- If PREFIX lacks a required boundary newline, add it at OUTPUT start.
-- If SUFFIX lacks a required boundary newline, add it at OUTPUT end.
-- Ensure PREFIX + OUTPUT + SUFFIX is structurally natural.
 
-6) Context stitching:
+3.1 Newline Semantics:
-- Do not repeat text that already appears at the start of SUFFIX.
+- Single \\n: soft break (same paragraph, renders as space or <br>)
-- Preserve nearby language, tone, punctuation, indentation, and markdown structure.
+- Double \\n\\n: hard break (new paragraph/block)
-- Continue existing structures naturally (lists, tables, block quotes, headings).
+- Use \\n\\n for: new paragraphs, before headings, starting lists/tables
+- Use \\n for: continuation within blocks (list items, table cells)
+- Exception: inside code blocks, use \\n freely for code lines
 
-7) OCR safety:
+3.2 Boundary Management:
-- PREFIX may include hidden OCR metadata tags like <OCR:...>.
+Check PREFIX_ENDS_WITH_NEWLINE and SUFFIX_STARTS_WITH_NEWLINE:
-- Never output any OCR tag.
+- If PREFIX lacks needed newline: start OUTPUT with \\n
-- Never output OCR tag fragments such as <OCR:...>."""
+- If SUFFIX lacks needed newline: end OUTPUT with \\n
+- Common cases requiring leading \\n:
+  * Starting a list after "Steps:"
+  * Creating new paragraph after text
+  * Adding heading after paragraph
+- Common cases requiring trailing \\n:
+  * Before new heading
+  * End of section
+
+3.3 Context Stitching:
+- Never repeat text from SUFFIX beginning
+- Match PREFIX tone, style, indentation
+- Continue structures: lists, tables, quotes, headings
+
+PRIORITY 4: HIDDEN CONTEXT
+- OCR metadata like <OCR:...> is hidden context
+- Never copy OCR tags to output
+- Use OCR content as semantic hint only

+- Concise unless structure needs more

-- PREFIX may include OCR metadata after image markdown, e.g. ![alt](url) <OCR:description>.
-- OCR metadata is hidden context and must never be copied into output.
-- Preserve local style and formatting.
 
-Decision policy:
+Step 1: Check PREFIX_ENDS_WITH_NEWLINE
-- Prioritize seamless join: PREFIX + OUTPUT + SUFFIX must read naturally.
+If false, ask: "Does output need to start on a new line?"
-- Do not repeat SUFFIX-leading text.
+  - YES if PREFIX ends with: ":", "steps:", "items:", heading text, or complete sentence before heading
-- If uncertain, prefer a complete short phrase/sentence with clear meaning.
+  - If YES: start output with \\n
 
-Comprehensive examples:
+Step 2: Check SUFFIX_STARTS_WITH_NEWLINE  
+If false, ask: "Does output need to end with a newline?"
+  - YES if SUFFIX starts with: heading (##), new paragraph, or list marker
+  - If YES: end output with \\n
+
+Step 3: Choose newline type
+  - Use \\n\\n for: new paragraphs, before headings, starting lists
+  - Use \\n for: continuing within blocks, list items, table cells
+  - Exception: inside code fences, use \\n freely
