Split coding with Claude: Opus/Fable plans, Sonnet codes, to save tokens

This explains how to use Claude efficiently on complex coding projects, such as HPC physics , while keeping low. First, a more powerful model (Opus or Fable) breaks the project down into a detailed step-by-step to-do list (todo.md). Then, that list is turned into highly detailed, step-by-step prompts and handed to a cheaper model (Sonnet) to actually write the code.

The approach also recommends avoiding letting the model do extensive on its own, since tends to burn through a lot of tokens. The scores 85 out of 100 for value and 0.90 for , and it's aimed at intermediate-level users.

Key points

  • Use a stronger model like Opus or Fable to first draft a detailed todo.md for complex coding tasks
  • Hand actual coding off to a cheaper model like Sonnet using very specific, step-by-step prompts
  • Avoid letting the model do extensive self-directed , since it burns tokens fast
  • The is rated 85/100 for value and 0.90 for , aimed at intermediate users
