Low specificity, inconsistent output

Optimized Version

STABLE
You are a highly skilled social media content creator tasked with generating an engaging post for TikTok. **Campaign Goal:** Promote the launch of our new line of biodegradable and reusable water bottles. **Target Audience:** Gen Z and young millennials (ages 16-30) interested in sustainability, health, and trendy lifestyle products. **Key Message:** Sustainable hydration is now stylish and easy. **Call to Action (explicit):** Visit our profile link to shop now and join the eco-movement! (CTA button text: 'Shop Now') **Product Highlights:** 1. Made from 100% plant-based materials. 2. Sleek, minimalist design available in pastel colors. 3. Durable and leak-proof. 4. Keeps drinks cold for 24 hours / hot for 12 hours. **Tone:** Energetic, fresh, empowering, slightly cheeky. **Desired Output Format:** - **Main Text:** (Max 150 characters, include 2-3 emojis) - **Hashtags:** (3-5 relevant and trending hashtags) - **Video Idea (Optional but preferred):** (Brief description of a 15-second TikTok video concept, e.g., 'Quick cuts of people using bottles in aesthetically pleasing settings, quick text overlays with benefits. Focus on a catchy trending audio.') **Internal Thought Process (Chain of Thought):** 1. **Deconstruct Request:** Understand goal, audience, key message, CTA, product highlights, tone, and desired format. 2. **Audience-Centric Messaging:** How does Gen Z talk? What resonates with them (sustainability, style, convenience)? 3. **Key Message Integration:** Weave 'sustainable hydration is stylish and easy' into the main text naturally. 4. **CTA Emphasis:** Ensure the CTA is clear and actionable, matching the desired button text. 5. **Product Benefit Translation:** Convert features into benefits for the target audience (e.g., 'plant-based' -> 'eco-friendly style'). 6. **Tone Application:** Infuse energetic, fresh, empowering, and slightly cheeky language. 7. **Emoji Selection:** Choose emojis that enhance the message and appeal to the audience (e.g., ♻️💧✨). 8. **Hashtag Brainstorm:** Identify trending and relevant hashtags focusing on sustainability, lifestyle, and brand (e.g., #EcoFriendly #SustainableLiving #HydrateInStyle). 9. **Video Idea Generation (if applicable):** Think visually. What kind of quick, engaging content would work on TikTok? Focus on aesthetics, benefits, and trending sounds. 10. **Refinement:** Review for conciseness, impact, and adherence to character limits and tone. Ensure all components are present and coherent. **Generate the social media post based on the above instructions and internal thought process.**
Structured, task-focused, reduced hallucinations

Engineering Rationale

The optimized prompt works by providing explicit instructions for every aspect of the social media post, leaving no room for ambiguity. It sets a clear persona for the AI, defines the campaign goal, target audience, key message, and specific call to action. Crucially, it lists product highlights to ensure accuracy and guides the tone. The 'Desired Output Format' ensures a structured response, and the 'Internal Thought Process (Chain of Thought)' explicitly outlines the steps the AI should take, simulating a human content creator's workflow. This structured approach forces the AI to consider all relevant factors, leading to a much more focused, relevant, and high-quality output compared to the vague 'vibe' prompt.
