description	Fixes build errors for the Cursor Metro macOS app. Runs the build, parses xcodebuild errors, applies fixes, and re-builds until the build succeeds. Use when the user says /fb, "fix the build", or wants to fix compile errors in the Cursor Metro project.

Fix Build (/fb)

Fix the Cursor Metro app build by building, reading errors, and applying fixes until the build succeeds.

Workflow

1. Build from the project root:

   xcodebuild -project "CursorMetro.xcodeproj" -scheme "CursorMetro" -configuration Debug build 2>&1
   

   Capture full stdout and stderr.

2. Parse errors from xcodebuild output:

   • Look for lines like path/to/file.swift:line:column: error: message
   • Note file path (relative to project root), line, and message.

3. Fix each reported error in the source file(s):

   • Open the file at the given path.
   • Address the error (missing import, type mismatch, unknown symbol, etc.).
   • Prefer minimal, targeted edits.

4. Re-run the build. If new errors appear, repeat from step 2. Stop when the build succeeds.

5. Report to the user: either "Build fixed" and a brief summary of changes, or that the build is still failing and what remains.

Notes

• If you see "requires Xcode" or toolchain errors, tell the user to run:

  sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
  

• Swift errors often come in chains (one fix may clear several). Fix the first/root cause first, then rebuild.
• Do not guess at large refactors; fix only what the compiler reports unless the user asks for more.
