Anthropic's official Opus 5 prompting guide is mostly about what to delete
Eight prompts you can copy straight into production, plus one counterintuitive catch: tell it to report only high-severity issues and it may genuinely report fewer.
⚑ The material comes from Anthropic's own documentation, describing how to tune its own model — capability claims and recommended settings are self-reported. The five-level breakdown, error details, and cache minimum come from the Effort docs and migration guide on the same site; the text flags each one where it appears.
