I spent a couple of months working with a tool along those lines. Unfortunately, it's one of those issues where it won't work specifically without the galactic emperor mandating these tools under pain of death. A colleague using VS Code would commit code with unbalance parentheses. The tooling was smart enough that it could load the file, even though it wasn't parsable, but there was no structural was to fix the missing closing brace. Adding a closing brace automatically inserted another opening brace, leaving the original mismatch.
