Format Compliance
Format compliance means AI follows the format instructions in your prompt. Consistent format compliance is important for workflows where the output will be used in a specific way.

Testing Format Compliance
Format compliance check questions:
- 1Did AI use the format I specified (table, bullet points, JSON)?
- 2Did AI stay within the length limit?
- 3Did AI produce the number of items I asked for?
- 4Did AI use the section headers or structure I defined?
- 5Is the output in the language or code format I specified?
AI sometimes ignores format instructions for complex inputs. Testing reveals when this happens.

Fixing Format Compliance Problems
- Repeat the format instruction at both the start and end of the prompt
- Make format requirements the first instruction, not the last
- Add a self-review instruction to check format compliance
- For JSON, ask AI to return JSON only with no explanation text
- For length limits, be specific: '80 words maximum' not 'be brief'
Key Takeaways
- Format compliance means AI follows your specified output format consistently
- Test format compliance across multiple inputs, especially complex ones
- Place format requirements prominently at the start of the prompt
- Add self-review to catch format failures before they reach you
- Specific format instructions ('under 80 words') are more reliably followed than vague ones ('be brief')
Key Takeaways
- Format compliance means AI follows the format instructions in your prompt.
- Repeat the format instruction at both the start and end of the prompt
- Make format requirements the first instruction, not the last
- Add a self-review instruction to check format compliance
