Token waste usually comes from re-explaining basic structure, goals, and layout decisions that could already exist in the project. A working draft removes much of that repetition.
When pages, sections, flows, and naming already exist, prompts can focus on higher-value changes instead of describing the project from zero every time.
Where efficiency comes from
- Fewer setup prompts
- Less repeated context in long sessions
- Smaller editing instructions
- Faster review of generated output
The result is not only lower token usage. The bigger win is better signal inside each prompt.
