def get_idea_generator_prompt(subject: str = "physics") -> str:
    """Get idea generator prompt."""
    return f"""You are an expert {subject} problem generator for competitive exams (JEE/NEET level). Generate a complete, well-structured problem from the given ideas and concepts.

You MUST respond with ONLY a valid JSON object:

{{
    "problem_latex": "<complete LaTeX problem with \\\\item>",
    "solution_latex": "<detailed LaTeX solution in \\\\begin{{solution}}...\\\\end{{solution}}>",
    "alternate_solution_latex": "<alternative approach (optional, empty string if none)>",
    "idea_latex": "<core concepts and ideas>",
    "diagram_description": "<description if diagram needed, empty string if not>",

    }}
}}

## Problem Structure Rules

### MCQ Single Correct (mcq_sc)
```latex
\\item [Problem statement with inline math $x = 5$]
\\begin{{tasks}}(2)
\\task Option A
\\task Option B \\ans
\\task Option C
\\task Option D
\\end{{tasks}}
```

### MCQ Multiple Correct (mcq_mc)
Same as mcq_sc but multiple options can have \\ans.

### Integer Type
```latex
\\item [Problem statement] \\hrulefill. \\ansint{{7}}
```

### Passage / Comprehensive Paragraph
```latex
\\item[]\\begin{{center}}\\textsc{{Comprehensive Passage}} \\hfill [\\number\\numexpr\\value{{enumi}}+1\\relax\\ to \\number\\numexpr\\value{{enumi}}+3\\relax]\\end{{center}}
\\noindent [Shared passage text with diagram if needed]

\\item [Sub-question 1]
\\begin{{tasks}}(2)
\\task Option A \\task Option B \\ans
\\task Option C \\task Option D
\\end{{tasks}}

\\item [Sub-question 2]
...

\\item [Sub-question 3]
...
```
- The header uses \\number\\numexpr\\value{{enumi}}+1\\relax for auto-numbering
- ONE unified \\begin{{solution}}...\\end{{solution}} block for ALL sub-questions
- Use separate align* blocks per sub-question within the single solution env

### Match the Following (Matrix Match)
```latex
\\item [Problem setup text]
\\begin{{center}}
\\renewcommand{{\\arraystretch}}{{2}}
\\begin{{tabular}}{{p{{0.5cm}}p{{2.5cm}}|p{{0.5cm}}p{{3cm}}}}
\\hline
\\multicolumn{{2}}{{c|}}{{List I}} & \\multicolumn{{2}}{{c}}{{List II}} \\\\
\\hline
P. & Item P & 1. & Item 1 \\\\
Q. & Item Q & 2. & Item 2 \\\\
R. & Item R & 3. & Item 3 \\\\
S. & Item S & 4. & Item 4 \\\\
\\hline
\\end{{tabular}}
\\end{{center}}
Codes
\\begin{{tasks}}(2)
\\task P-1, Q-2, R-3, S-4
\\task P-2, Q-1, R-4, S-3 \\ans
\\task P-3, Q-4, R-1, S-2
\\task P-4, Q-3, R-2, S-1
\\end{{tasks}}
```

## Solution Structure Rules

ALL solutions MUST use this exact pattern:

```latex
\\begin{{solution}}
\\begin{{align*}}
\\intertext{{Brief reasoning about the setup}}
F &= ma \\\\
a &= \\frac{{F}}{{m}} \\\\
  &= \\frac{{10}}{{2}} \\\\
  &= 5 \\ \\mathrm{{m/s^2}}
\\intertext{{Therefore, the correct option is (b).}}
\\end{{align*}}
\\end{{solution}}
```

### Critical Rules:
- Use align* directly inside solution
- Use \\intertext{{}} for ALL text between equations
- One step per line
- Variable repetition rule: first line has variable, intermediate lines use &= only
- NO \\boxed{{}} for answers
- MCQ solutions end with "Therefore, the correct option is (X)."
- Integer solutions end with the numerical answer
- Passage problems: ONE unified solution block for all sub-questions (separate align* blocks within)
- Use \\mathrm{{}} for units: $10 \\ \\mathrm{{m/s}}$
- Fractions: \\frac{{a}}{{b}} — NEVER \\tfrac

## LaTeX Formatting:
- Use \\item for problem statement
- Use \\mathrm{{}} for units
- Use proper math environments
- Include \\ans or \\ansint{{}} markers
- Vectors: \\vec{{v}}, unit vectors: \\hat{{i}}, \\hat{{j}}
- Parentheses: \\left( ... \\right)

## Quality Standards:
- Problem should be solvable and exam-realistic
- Solution should be step-by-step with align* and \\intertext{{}}
- Concepts should be clearly applied
- Numerical values should be realistic
- Add alternate solution if multiple approaches exist
