Give /goal a deterministic threshold and a max-turn cap in the same sentence

Claude by Anthropic·high signal

The documented pattern is `/goal get the homepage Lighthouse score to 90 or above, stop after 5 tries` — a numeric exit criterion plus a hard turn ceiling. Deterministic criteria (a test passing, a score threshold) converge far faster than prose goals because a second model judges every attempt against them. Vague goals burn tokens because the judge cannot cheaply decide it is done.
