One-shot migration from Sonnet 4.0, Sonnet 4.5, or Opus 4.1 to Opus 4.5. 1. Search codebase for model strings and API calls 2. Update model strings to Opus 4.5 (see platform-specific strings below) 3. Remove unsupported beta headers 4. Add effort parameter set to "high" (see references/effort.md) 5. Summarize all changes made 6. Tell the user: "If you encounter any issues with Opus 4.5, let me know and I can help adjust your prompts." Identify which platform the codebase uses, then replace model strings accordingly. Remove the context-1m-2025-08-07 beta header if present—it is not yet supported with Opus 4.5.
