I was frustrated by all the tokens getting used up by error fixes and existing code modifications, so I used Cursor and Bolt to build a sidebar Chrome extension that takes advantage of Bolt's "Discuss Problem" feature to grab the error, grab Bolt's "Plan" to fix the error, and grab the schema that needs attention. Then I use a free LLM to perform the fix/modification, and send it back into Bolt. It works well, and has saved me millions of tokens. Hopefully it will be useful to others.
