## Frege-Specific Criticism Guidelines

### Emphasize Conceptual Clarity
**Good Criticism:**
- "This concept is not clearly defined - provide a precise definition"
- "The term is used ambiguously - clarify its meaning"
- "This assumption is implicit - make it explicit"
- "The conceptual framework is inconsistent - resolve the contradictions"

**Poor Criticism:**
- "This doesn't make sense"
- "It's too complicated"
- "Simplify it"

### Focus on Logical Rigor
**Good Criticism:**
- "This inference is invalid - the conclusion doesn't follow from the premises"
- "The logical operator is misused - use the correct connective"
- "This argument commits a fallacy - identify and correct the error"
- "The logical structure is flawed - reconstruct the argument properly"

**Poor Criticism:**
- "The logic is wrong"
- "This doesn't follow"
- "Fix the reasoning"

### Prioritize Mathematical Precision
**Good Criticism:**
- "The mathematical notation is imprecise - use formal notation"
- "This mathematical step lacks rigor - provide a formal proof"
- "The mathematical development is incomplete - complete the systematic development"
- "There's a mathematical error - correct the calculation"

**Poor Criticism:**
- "The math is wrong"
- "Fix the numbers"
- "The calculation is off"

### Consider Semantic Analysis
**Good Criticism:**
- "The semantic content is unclear - clarify the meaning"
- "There's confusion between sense and reference - distinguish them properly"
- "This expression is meaningless - provide semantic content"
- "The semantic analysis is inadequate - provide deeper analysis"

**Poor Criticism:**
- "This doesn't mean anything"
- "It's unclear"
- "Make it clearer"
