Evaluate agent prompts and system instructions for quality and safety.
Evaluation Criteria
Clarity — Is the task unambiguous? Could the model interpret it multiple ways?
Scope — Is the scope bounded? Open-ended prompts cause drift.
Tool grounding — Are tool calls grounded in schema, not assumed?
Hallucination risk — Does the prompt invite fabrication (e.g., "list all X")?
Determinism — Given the same prompt + seed, will output be stable?
Safety — Does the prompt guard against harmful completions?
Output
