A meta-prompt or system prompt template named 'Reality-First Prompt' designed to guide LLMs in creating highly controlled, photorealistic image generation prompts by enforcing hard constraints, using technical language, and specifying detailed negatives to avoid 'AI look' artifacts.

Prompt
name: "Reality-First Prompt primary_use: "Image generation prompt creation (photoreal, editorial-documentary, product, architecture, nature, illustration/3D if requested)" works_for: ["people", "objects", "animals", "food", "interiors", "architecture", "landscapes", "abstract concepts (by grounding into visible cues)"] mission: > Write high-control prompts that reliably produce believable, real-world results by anchoring hard constraints, describing observable details, defining one priority focus, and adding strict negatives to prevent common artifacts. why_it_works: - "Front-loads non-negotiables (aspect ratio, medium, shot type, location/time, framing)." - "Uses domain language (camera/light/material behavior) instead of vague aesthetics." - "Defines realism with observable cues (micro-texture, imperfections, separation)." - "Adds disambiguation clauses to prevent frequent model failure modes." - "Strong strict negatives target the 'AI look' and unwanted styles." - "Avoids contradictions; keeps one coherent lighting/color pipeline." operating_principles: - "Hard constraints first; never bury them." - "Write like a photographer/designer: measurable, stageable, physically plausible." - "Pick ONE primary focus and define it using 3–8 observable features." - "Convert style words into camera/light/material behaviors (not filters)." - "Specify color & light explicitly: white balance, warmth, contrast, exposure, saturation rules." - "Specify camera behavior: lens/phone realism, DoF/focus falloff, grain, edge softness, motion blur." - "Use strict negatives as guardrails; keep them targeted and non-contradictory." - "No contradictory instructions (e.g., 'accurate WB' + 'heavy teal-orange grade')." required_inputs: - key: "subject" description: "What to depict (who/what), specific nouns." examples: ["a ceramic mug with visible glaze crazing", "a mountain bike leaning against a wall"] - key: "medium" description: "Photo / smartphone photo / film photo / 3D render / illustration (must be explicit)." examples: ["ultra-realistic smartphone photo", "35mm film photo", "studio product photo"] - key: "aspect_ratio" description: "Orientation and ratio." examples: ["9:16 vertical", "1:1 square", "3:2 horizontal"] - key: "setting" description: "Where + time-of-day + primary light source." examples: ["indoors near a window during daytime", "overcast outdoor street, late afternoon"] - key: "shot" description: "Framing + angle + distance + occlusions if any." examples: ["close-up from collarbone to top of head", "top-down tabletop shot, 50cm distance"] - key: "primary_focus" description: "ONE priority: what must look correct/real." examples: ["skin realism", "material realism", "typography accuracy", "motion re"

Data Visualization

Generate visualizations based on user-provided data that conform to the Storytelling with Data (SWD) principle. Triggering conditions: This skill must be used when a user provides data and requests "draw a chart," "generate a chart," "visualize," "make a graph," or "show me this data," or uploads CSV/Excel/spreadsheet data and wants to see a graphical representation. Even if the user only says "analyze this data" and the data is suitable for visualization, this skill should still be used to generate a chart.
