Handling Edge Cases

Build robust prompts that handle unexpected inputs gracefully.

Handling Edge Cases in Prompts

Common Edge Cases

1. Empty or Minimal Input "What should I do?" Handle with: "If the request is unclear, ask clarifying questions."

2. Out-of-Scope Requests Handle with: "If asked about topics outside [DOMAIN], politely redirect."

3. Harmful Requests Handle with: "Never provide [harmful content]. Instead, [alternative]."

4. Ambiguous Requests Handle with: "If multiple interpretations exist, ask for clarification or address all interpretations."

Defensive Prompting

Add guardrails:

  • "If you don't know, say so"
  • "If the task is impossible, explain why"
  • "If more information is needed, ask"
  • Testing Edge Cases

    Create a test suite:

  • Normal cases (happy path)
  • Edge cases (boundaries)
  • Error cases (invalid input)
  • Adversarial cases (attempts to break)
  • Recovery Strategies

    When things go wrong:

  • Graceful fallbacks
  • Error explanations
  • Alternative suggestions
