讓 Claude 直接讀取 xcodebuild 編譯錯誤的 Claude Code Mod

I built a mod for Claude Code with the new mod system. It's for anyone who lets Claude run xcodebuild. When a Bash command fails with long output, Claude Code gives the model the start and the end and cuts out the middle. A failing xcodebuild puts the compiler errors in the middle. On a small Swift package with three compile errors, the log was 295 lines and Claude received 10,039 characters, none of them an error message. It knew which files failed but not why, so it grepped the source and re-ran the build through its own filter. It: - Appends -resultBundlePath to the xcodebuild command and reads errors, warnings and test failures from Xcode's result bundle with xcresulttool. - Replaces what Claude reads with a summary: in the same test, 499 characters with every reported error's file, line and column. The transcript keeps the raw output. - Shows a pane with errors grouped by file, failed tests, warnings and recent builds. It doesn't: It didn't make Claude fix the project in fewer builds in my test (three either way) but it does make it fix the issues more efficiently as it doesn't need to search the errors. It only sees builds Claude runs through Bash, not builds inside scripts, make or fastlane. swift build is read from the log only.
