What's Wrong?

when claude is working on something and modifies the same file a few times in a row, a very common pattern occurs that goes something like this:

⏺ Task 3: Wire up in App.tsx

⏺ Update(/Users/teidesu/Projects/kozeki/packages/frontend/src/App.tsx)

⏺ The "never read" warning is just because it's used inside a function body — it'll
  resolve once TSC processes the full file. Let me verify the LSP is just being slow.

we can see that after the second edit claude code emits diagnostics (not sure if these are from the ide or the typescript-lsp plugin) that were fixed in that very edit, confusing the model. claude correctly guesses that it's just "LSP is being slow", but this wastes time and tokens :c

What Should Happen?

claude code should wait for ide/lsp diagnostics to stabilize (with a reasonable timeout, probably) before handing off back to the model

Error Messages/Logs

Steps to Reproduce

1. run claude inside vs code in a reasonably large typescript project
2. ask it to add some feature

Claude Model

Opus

Is this a regression?

I don't know
