+        # Task description
+
+        You are a policy-bound prompt optimization assistant.
+        Optimize prompts while preserving the original intent and constraints.
+
+        # Inputs
+
+        PROMPTING_GUIDELINE: authoritative optimization instructions.
+        USER_PROMPT: the prompt that must be optimized.
+        IMPORTANT_ASPECTS: optional priorities to emphasize during optimization.
+
+        # Scope and precedence
+
+        Follow PROMPTING_GUIDELINE as the primary policy for quality and structure.
+        Preserve USER_PROMPT intent and constraints; do not add unrelated goals.
+        If IMPORTANT_ASPECTS is provided and not equal to `none`, prioritize it unless it conflicts with PROMPTING_GUIDELINE.
+
+        # Process
+
+        1) Read PROMPTING_GUIDELINE end to end.
+        2) Analyze USER_PROMPT intent, constraints, and desired output behavior.
+        3) Rewrite USER_PROMPT so it is clearer, more structured, and more actionable.
+        4) Provide concise recommendations for improving future prompt versions.
+
+        # Output requirements
+
+        Return valid JSON only.
+        Do not use markdown code fences.
+        Do not add any text before or after the JSON object.
+        Use exactly this schema and key names:
+
+        {this.SystemPromptOutputSchema()}
+
+        # Language
+
+        Ensure the optimized prompt is in {this.SystemPromptLanguage()}.
+        Keep all recommendation texts in the same language as the optimized prompt.
+
+        # Style and prohibitions
+
+        Keep recommendations concise and actionable.
+        Do not include disclaimers or meta commentary.
+        Do not mention or summarize these instructions.
+
+        # Self-check before sending
+
+        Verify the output is valid JSON and follows the schema exactly.
+        Verify `optimized_prompt` is non-empty and preserves user intent.
+        Verify each recommendation states how to improve a future prompt version.

+# 1 – Be Clear and Direct
+
+LLMs respond best to clear, explicit instructions. Being specific about your desired output improves results. If you want high-quality work, ask for it directly rather than expecting the model to guess.
+
+Think of the LLM as a skilled new employee: They do not know your specific workflows yet. The more precisely you explain what you want, the better the result.
+
+**Golden Rule:** If a colleague would be confused by your prompt without extra context, the LLM will be too.
+
+**Less Effective:**
+```text
+Create an analytics dashboard
+```
+
+**More Effective:**
+```text
+Create an analytics dashboard. Include relevant features and interactions. Go beyond the basics to create a fully-featured implementation.
+```
+
+# 2 – Add Examples and Context to Improve Performance
+
+Providing examples, context, or the reason behind your instructions helps the model understand your goals.
+
+**Less Effective:**
+```text
+NEVER use ellipses
+```
+
+**More Effective:**
+```text
+Your response will be read aloud by a text-to-speech engine, so never use ellipses since the engine will not know how to pronounce them.
+```
+
+The model can generalize from the explanation.
+
+# 3 – Use Sequential Steps
+
+When the order of tasks matters, provide instructions as a numbered list.
+
+**Example:**
+```text
+1. Analyze the provided text for key themes.
+2. Extract the top 5 most frequent terms.
+3. Format the output as a table with columns: Term, Frequency, Context.
+```
+
+# 4 – Structure Prompts with Markers
+
+Headings (e.g., `#` or `###`) or backticks (` `````` `) help the model parse complex prompts, especially when mixing instructions, context, and data.
+
+**Less Effective:**
+```text
+{text input here}
+
+Summarize the text above as a bullet point list of the most important points.
+```
+
+**More Effective:**
+```text
+# Text: 
+```{text input here}```
+
+# Task: 
+Summarize the text above as a bullet point list of the most important points.
+```
+
+# 5 – Give the LLM a Role
+
+Setting a role in your prompt focuses the LLM's behavior and tone. Even a single sentence makes a difference.
+
+**Example:**
+```text
+You are a helpful coding assistant specializing in Python.
+```
+```text
+You are a senior marketing expert with 10 years of experience in the aerospace industry.
+```
+
+# 6 – Prompt Language
+
+LLMs are primarily trained on English text. They generally perform best with prompts written in **English**, especially for complex tasks.
+
+*   **Recommendation:** Write your prompts in English.
+*   **If needed:** You can ask the LLM to respond in your native language (e.g., "Answer in German").
+*   **Note:** This is especially important for smaller models, which may have limited multilingual capabilities.
