createBasic runs go mod init without setting Cmd.Dir, but sets Cmd.Dir for go mod tidy. Since the function already receives projectPath, it would be more robust/consistent to set Dir for both commands (and avoid relying on a prior os.Chdir). This also prevents go.mod being created in the wrong directory if createBasic is ever called without createProject.

Suggested change
if err := runCmd(execCommand("go", "mod", "init", modName)); err != nil {
return err
}
//Execute go mod tidy in the project directory
installModules := execCommand("go", "mod", "tidy")
installModules.Dir = fmt.Sprintf("%s%c", projectPath, os.PathSeparator)
modInit := execCommand("go", "mod", "init", modName)
modInit.Dir = projectPath
if err := runCmd(modInit); err != nil {
return err
}
// Execute go mod tidy in the project directory
installModules := execCommand("go", "mod", "tidy")
installModules.Dir = projectPath

go mod tidy can be affected by an enclosing go.work (workspace) file. Elsewhere the repo explicitly forces GOWORK=off when running go mod ... commands (see cmd/internal/go_mod.go:33-55). Consider applying the same environment filtering here for both go mod init and go mod tidy so project generation is isolated from the caller’s workspace.

This change adds a new externally-visible step (go mod tidy) during fiber new, but current tests don’t assert that tidy is invoked. Consider adding a unit test that captures execCommand invocations and verifies go mod tidy runs after go mod init.
