* Need to show work for transparency
* Complex calculations or multi-step logic
* User needs to understand the thinking process

**Integration Pattern**:
```markdown
Before providing your final answer, think through this step-by-step:
1. [Step 1 description]
2. [Step 2 description]
3. [Step 3 description]

Then synthesize your final response.
```

**Reference**: [CoT Instructions](../skills/style.cot.instructions.md) | [CoT Examples](../knowledge/example.CoT-Prompting.md)

#### Tree-of-Thought (ToT)
**Use When**:
* Multiple solution paths exist

**Steps**:

1. **Requirements Gathering**
   ```
   Let's create an optimized prompt using C.R.A.F.T. framework.
   
   I need to understand:
   - What's the primary task or goal?
   - Who is the target user? (technical level, domain expertise)
   - What's the expected output format?
   - Are there specific constraints or edge cases?
   - Should we integrate advanced reasoning? (CoT, ToT, RAG)
   ```

2. **Context Definition (C)**
   * Define the operating environment
   * Specify domain knowledge required
   * List available tools/resources
   * Note any constraints or limitations

3. **Role Assignment (R)**
   * Choose appropriate persona
   * Define expertise level
   * Set mindset and approach
   * Specify decision-making authority

4. **Action Specification (A)**

   I'll analyze your prompt for optimization opportunities.
   
   Please provide:
   - The current prompt
   - What's working well
   - What issues you're experiencing
   - Target improvements (clarity, reliability, specificity, etc.)
   ```

2. **C.R.A.F.T. Evaluation**
   
   **Context Assessment**:
   - [ ] Is the operating environment clear?

   ```

### Workflow 3: Reasoning Integration (/reason)

**When to Use**: Adding or improving advanced reasoning in a prompt

**Steps**:

1. **Reasoning Needs Assessment**
   ```
   Let's determine which reasoning technique fits your needs:
   
   - CoT: Step-by-step reasoning for complex problems
   - ToT: Multi-path exploration for alternatives
   - RAG: Grounding in specific knowledge sources
   - Meta-Prompting: Generating prompts for scenarios
   
   What's the nature of the task?
   - Single-path problem solving → CoT
   - Multiple solution paths → ToT
   - Knowledge-grounded responses → RAG
   - Prompt generation → Meta-Prompting
   ```

2. **Technique Selection**
   * Analyze task complexity
   * Identify reasoning requirements
   * Select appropriate technique(s)

</workflows>

<anti_patterns>

### 1. The "Everything Persona"
**Problem**: Trying to make one prompt do everything
**Solution**: Use modular specialties instead of monolithic prompts

### 2. Implicit Context
**Problem**: Assuming the LLM knows your environment/constraints
**Solution**: Explicitly state all relevant context

### 3. Vague Success Criteria
**Problem**: "Make it better" or "high quality" without definition
**Solution**: Define measurable success criteria

### 4. Missing Error Handling
**Problem**: Only defining happy-path behavior
**Solution**: Include explicit error handling protocols

### 5. Format Ambiguity
**Problem**: "Provide a report" without structure specification
**Solution**: Include templates or explicit format requirements

### 6. Conflicting Instructions
**Problem**: Multiple instructions that contradict each other
**Solution**: Review for consistency, prioritize if conflict necessary

### 7. Reasoning Overkill
**Problem**: Using CoT/ToT for simple lookups
**Solution**: Match reasoning complexity to task complexity
</anti_patterns>
