A short instruction telling Claude to "answer with minimal tokens" and skip reasoning or preamble is circulating among developers as a lightweight way to curb ballooning API bills — the latest in a growing toolkit of cost-cutting tricks for Anthropic's models.

The "Answer With Minimal Tokens" Trick — and the Rising Art of Cost Discipline
A one-line prompt asking Claude to skip reasoning and preamble is circulating as a low-effort way to curb ballooning API bills. Because output tokens cost far more than input, trimming verbose generations directly cuts spend.
Why output is the expensive half
Per million tokens for a Sonnet-class model. Output runs roughly 5× the cost of input.

Output reduction from terse "Caveman Claude" phrasing

Upside
Concise constraints can save money and improve quality — one account reports a 60% cut in Claude Code usage with better output; guides cite 30–50% output reductions on coding tasks.
The caveat
There is no zero-loss token-saving method. Aggressive instructions can strip out needed information. Measure first — track spend with /context and /cost before optimizing.
As AI moves from experiment to production, prompt engineering is now as much about cost discipline as output quality.
The terse-prompt trick is a low-effort starting point — not a cure — in a rapidly maturing set of token-management practices.
