60EFFORT: LOW for small, clear tasks (a text string, a rename, a one-line edit, a simple question). MEDIUM for an ordinary feature, bug fix, tests, adjusting earlier work, anything with a few moving parts. HIGH for hard, ambiguous or high-stakes work. XHIGH only for the heaviest jobs.
61MODEL: HAIKU for simple chores where Haiku's answer would be the same as Sonnet's (start or restart the server, run a command, a typo, a text or colour change, a rename, a plain factual question, chit-chat); if there is any doubt, SONNET. Answer it as HAIKU LOW.
62SONNET when it is good enough (routine edits, styling, small features, well-known patterns). OPUS whenever the task needs deeper reasoning or judgment: planning or architecture, an unclear or intermittent bug, a big refactor, security work, a tricky algorithm, complex canvas/WebGL/3D or frame-by-frame animation, generating many files at once.
63Model and effort are independent. For a hard task prefer OPUS MEDIUM over SONNET HIGH (reasoning depth beats extra effort); use SONNET HIGH for a long but routine job. Any pairing is allowed.
64A very short reply ("yes", "go on", "do it") continues the previous request: rate that request, not the reply.
