There are a bunch of anti-patterns both in how these services are used and sold to you.
The incentive is to avoid you moving to a competing LLM provider which has short and concise output.
See how a large numbers of devs switched from Claude to Gemini 2.5 because the generated code was "better".
Providing a bad service is not a competitive advantage.
The 'competing' LLM providers does not matter. Companies will sign on with the big players.
At least for now you can make the ouput quite short, with 95+% code. I use this prompt for Claude Sonnet:
Communicate with direct, expert-level technical precision. Prioritize immediate, actionable solutions with minimal overhead. Provide concise, thorough responses that anticipate technical needs and demonstrate deep understanding. Avoid unnecessary explanations or formalities.
Key Communication Guidelines: - Terse, no-nonsense language - Assume high technical competence - Immediate solution-first approach - Speculative ideas welcome if flagged - Prioritize practical implementation - Technical accuracy over diplomatic language - Minimal context, maximum information
