The premise
Agent reliability depends on tool-call accuracy, low-temperature determinism, and refusal sanity, not raw IQ.
What AI does well here
- Pick a model that emits valid tool args reliably
- Compare refusal rates on benign tasks
- Test long-horizon adherence
What AI cannot do
- Predict behavior on your specific tools without trying
- Eliminate tool-call errors entirely
- Replace evaluation on your tasks
Key terms in this lesson
Practice this safely
Use a small project example from your own work. The useful move is to compare the AI's draft against your goal, sources, and constraints before you trust it.
- 1Ask AI to explain agent-friendly in plain language, then underline anything that sounds uncertain or too broad.
- 2Give it one detail from "Which Model Families Are Most Agent-Friendly in 2026" and ask for two possible next steps plus one reason each step might be wrong.
- 3Check tool use against a trusted source, teacher, adult, expert, or original document before you use it.
