⚠ No role assigned

Tell the model who it should be. 'You are a senior copywriter…' beats no framing.

⚠ Output format unspecified

State what format you want back: JSON, bullets, table, markdown, etc.

• No example provided

Consider adding one example of ideal output. Few-shot usually beats instructions alone.

• No constraints

Add explicit 'don't' rules — e.g., 'Don't add intro phrases', 'Don't repeat the input'.

⚠ Too short

Very short prompts force the model to guess context. Aim for 3–8 sentences for non-trivial tasks.

• Pleasantries

Polite words don't hurt, but they don't help. Safe to remove for brevity.

Improved prompt

# Role

Return a clear, structured answer. Use bullet points or a table where it aids scanning.

# Stop condition

This is a rule-based linter, not a model call. It catches common issues so you can fix them before spending tokens.
