The fixPermissions() function was running chmod -R 755 on the entire ~/.claude directory, making every file executable including configs, markdown, and JSON files. This is incorrect on Linux/WSL where only directories and scripts should have the execute bit. Replaces the blanket chmod -R 755 with granular permissions: - Directories: 750 (rwxr-x---) - Regular files: 640 (rw-r-----) - Scripts (.ts, .sh, .py): 750 (rwxr-x---) Also uses find -exec ... + instead of \; for better performance.

Summary
chmod -R 755(makes ALL files executable) with granular Linux permissions750(rwxr-x---), files:640(rw-r-----), scripts:750(rwxr-x---)find -exec ... +instead of\;for better performanceProblem
fixPermissions()in INSTALL.ts runschmod -R 755on the entire~/.claudedirectory, making every file executable — including JSON configs, markdown files, and YAML. On Linux/WSL, only directories and scripts should have the execute bit. This is both a security issue (unnecessary execute permissions) and breaks expectations for standard Linux file permissions.The function also runs
chmod -R 755three times (steps 1, 3, and the script step), which is redundant.Fix
Replace the three-step chmod/chown/chmod approach with:
chown -R— set ownership firstfind -type d -exec chmod 750— directories onlyfind -type f -exec chmod 640— regular files (no execute)find -type f -name "*.ts|*.sh|*.py" -exec chmod 750— scripts onlyTest plan
.tsand.shfiles have execute permission (750).json,.md,.yamlfiles do NOT have execute permission (640)Fixes #484
