## Background

Research with Gemini identified key issues with mistral-nemo and tool calling:
- "Pre-computation Hallucination" - model answers before using tools
- High default temperature (0.7-0.8) causes wandering
- Model is "chatty and confident" - needs explicit constraints

## Key Recommendations from Gemini Research

1. **Temperature 0.0** for tool-calling agents (deterministic, follows schema)
2. **Chain of Thought (CoT)** - force step-by-step reasoning
3. **Negative constraints** - tell model what NOT to do (Nemo responds better)
4. **Explicit tool descriptions** - verbose docstrings with "never estimate yourself"
5. **"Strictly tool-based assistant"** pattern - NO internal knowledge claim
