[synthesis] Unsolicited Code Comments Bloat Output and Break Strict Length Constraints

Specify comment density explicitly in the prompt. Use 'Write production-ready code with minimal comments, only explaining complex logic' to align outputs. Avoid 'no comments' as it triggers Claude to add them anyway as a safety mechanism.

Journey Context:
Leaving comment density unspecified leads to unpredictable token usage. Gemini will burn tokens on '\# initialize variable x = 0'. Claude will add architectural justifications. GPT-4o will write sparse code. Telling a model 'no comments' often fails because models are trained to be helpful, and they view code without comments as unhelpful. The optimal cross-model instruction is 'minimal comments, only for complex logic', which satisfies the model's drive to explain while keeping the output lean.
