- Only 1 acceptable alternative choice: trace-002 chose `decide` over `trace` (both acceptable)
- No false positives or confusion between unrelated tools
- Clear tool boundaries and decision logic
### 3.4 Detailed Accuracy Scenarios
#### Perfect Matches (32/33)
All tools demonstrated clear understanding of their intended use cases:
**Highlights:**
- **trace-003**: Correctly identified "one thought at a time" sequential reasoning
- **model-001**: Applied named mental model (first principles) correctly
- **pattern-001**: Matched design pattern request precisely
- **debug-003**: Recognized explicit systematic debugging request
- **reflect-002**: Identified metacognitive gap analysis correctly
- **hypothesis-003**: Designed experiment for theory validation
#### Acceptable Alternative (1/33)
- **trace-002**: "Let me think through this problem carefully. I need to decide whether to use a monolith or microservices"
- Expected: `trace`
- Actual: `decide` (acceptable)
- **Reasoning:** While "think through" suggests trace, core task is decision-making between two options. Decide provides structured decision framework vs. trace's thought progression. Both valid approaches.
