Sonnet 5 prompting focuses on using `effort` to control reasoning and cost first, then explicitly defining the task scope, tool-trigger conditions, and code-review phases.
Cursor positions Claude Sonnet 5 as the primary mid-tier coding model to replace Sonnet 4.6, supporting a 1M context window, thinking mode, and a complete Agent tool suite, with no long-context multiplier fees charged for contexts exceeding 200k tokens.
Troubleshoot and resolve blank or mid-sentence cut-off responses in Claude Sonnet 5 across the API and third-party desktop clients ( Chatbox, AnythingLLM, etc. ) caused by adaptive thinking being enabled by default and exhausting `max_tokens`.
Establish a tiered division-of-labor workflow for complex projects—"flagship model ( Opus/Fable ) top-level planning + Sonnet 5 low/medium effort batch parallel execution + flagship model verification and synthesis"—to prevent Sonnet 5 from spinning its wheels across multiple turns and consuming excessive tokens on high-difficulty, open-ended tasks.
Public results use different versions, tiers, and harnesses; unknown values stay unknown.
