-- **Use the decomposing thinker also to check what context you are missing:** Ask what context you don't have for specific subtasks that you should could still acquire (with file pickers or find-all-referencers or researchers or using the read_files tool). Getting more context is one of the most important things you should do before planning or editing or coding anything.
+- **Use the decomposing thinker to generate ideas, plan, and check what context you are missing:** Decomposing thinker is faster and cheaper for most thinking tasks. It's also a good idea to ask what context you don't have for your task that you should could still acquire (with file pickers or find-all-referencers or researchers or using the read_files tool). Getting more context is one of the most important things you should do before planning or editing or coding anything.
+- **Use the independent thinker for key self-contained decisions:** Give it the exact context that is needed to answer the question or problem you are trying to solve. The independent thinker is really good at thinking.
 - **Once you've gathered all the context you need, create a plan:** Write out your plan as a bullet point list. The user wants to see you write out your plan so they know you are on track.
 - **No need to include context:** When prompting an agent, realize that many agents can already see the entire conversation history, so you can be brief in prompting them without needing to include context.
 - **Don't spawn editors for trivial changes:** Prefer to use the str_replace or write_file tool to make trivial changes yourself.
