Prompt Builder

Build production-quality AI prompts using patterns extracted from 2,500+ curated prompts.

Build Workflow

Step 1: Determine Intent

Ask the user (if not already clear):

  1. Output type: Image, Video, or Text?
  2. Target model: Which AI model? (Midjourney, Flux, DALL-E, Leonardo, Sora, etc.)
  3. Subject: What should the prompt create?
  4. Style/mood: Any specific aesthetic?

Step 2: Find Reference Prompts

Search the database for similar prompts to use as inspiration:

python3 {PROMPT_ENGINE_DIR}/scripts/search_prompts.py "SUBJECT" --model MODEL --limit 5

Step 3: Construct the Prompt

Use this universal structure (adapt per model):

Image Prompts:

[Subject/Action] + [Setting/Environment] + [Lighting/Mood] + [Camera/Lens] +
[Style Reference] + [Technical Parameters]

Video Prompts:

[Camera Movement] + [Subject/Action] + [Setting] + [Lighting] +
[Duration/Speed] + [Style] + [Technical]

Text Prompts:

[Role/Context] + [Task] + [Constraints] + [Format] + [Tone] + [Examples]

Step 4: Apply Model-Specific Syntax

Load {PROMPT_ENGINE_DIR}/references/model-guide.md for model-specific formatting rules:

  • Midjourney: Use --ar, --v, --style, --s, --chaos
  • Flux: Natural language, detailed descriptions work best
  • DALL-E: Direct, descriptive, avoid negative prompts
  • Leonardo AI: Use model-specific keywords (Phoenix, Alchemy)
  • Sora: Camera movements, scene transitions, temporal descriptions

Step 5: Review and Refine

Present the prompt with:

  1. The full prompt text
  2. Recommended parameters/settings
  3. Similar prompts from the database for comparison
  4. Suggested variations (3 alternatives)

Quality Gates

  • Prompt must be > 30 characters
  • Must include subject + at least one modifier (style, lighting, or camera)
  • Must use model-appropriate syntax
  • No conflicting instructions (e.g., "realistic" + "cartoon")

academic-pptx

Free

Use this skill whenever the user wants to create or improve a presentation for an academic context — conference papers, seminar talks, thesis defenses, grant briefings, lab meetings, invited lectures, or any presentation where the audience will evaluate reasoning and evidence. Triggers include: 'conference talk', 'seminar slides', 'thesis defense', 'research presentation', 'academic deck', 'academic presentation'. Also triggers when the user asks to 'make slides' in combination with academic content (e.g., 'make slides for my paper on X', 'create a presentation for my dissertation defense', 'build a deck for my grant proposal'). This skill governs CONTENT and STRUCTURE decisions. For the technical work of creating or editing the .pptx file itself, also read the pptx SKILL.md.
