Loading Strategy

CRITICAL: Token Optimization Rules

1. featured.json ONLY: Can be fully loaded (small file, ~10 prompts)

   • Use when: vague requests, need inspiration, creating custom prompts

2. ALL OTHER FILES: NEVER fully load. Use Grep to search:

   Grep pattern="keyword" path="references/category-name.json"
   

   • Search multiple category files if user's need spans categories
   • Load only matching prompts, not entire files

Workflow

Step 1: Clarify Vague Requests

If user's request is too broad, ask for specifics using AskUserQuestion:

Vague Request	Questions to Ask
"Help me make an infographic"	What type? (data comparison, process flow, timeline, statistics) What topic/data?
"I need a portrait"	What style? (realistic, artistic, anime, vintage) Who/what? (person, pet, character) What mood?
"Generate a product photo"	What product? What background? (white, lifestyle, studio) What purpose?
"Make me a poster"	What event/topic? What style? (modern, vintage, minimalist) What size/orientation?

Step 2: Search & Match

1. Identify target category from signal mapping table
2. Use Grep to search relevant file(s) with keywords from user's request
3. If no match in primary category, search others.json
4. If still no match, load featured.json for inspiration

Step 3: Present Results

IMPORTANT: Recommend at most 3 prompts per request. Choose the most relevant ones.

For each recommended prompt, provide in user's input language:

### [Prompt Title]

**Description**: [Brief description translated to user's language]

**Prompt (English - use this for generation)**:

[Original English prompt from content field]

**Sample Images**:
![Sample 1](sourceMedia[0])
![Sample 2](sourceMedia[1])

**Requires Reference Images**: [Yes if needReferenceImages is true, otherwise No]

Step 4: Handle No Match

If no suitable prompts found:

1. Load featured.json completely
2. Analyze patterns from featured examples
3. Create a custom prompt based on:
   • Similar prompts in featured collection
   • User's specific requirements
   • Best practices from examples
