Why this is operational, not cosmetic
When request volume grows, prompt style becomes an infrastructure choice.
Extra tokens can raise cost per task, increase tail latency, and reduce throughput headroom at peak.
Practical policy
- keep conversational style for human-facing support and coaching,
- use compact structured prompts for automation lanes,
- track tokens per successful task, p95 latency, and cost per workflow.
Takeaway
Prompt tone still matters, but in production it should be intentional policy, not accidental drift.
Short note: bldrAgent teams can codify this by workflow stage, but the model applies across LLM platforms.
