Rules

MND001: No action specified for resource

Bad:

cookbook_file '/etc/nscd.conf' do
    owner 'root'
    group 'root'
end

package 'build-essential'

Good:

cookbook_file '/etc/nscd.conf' do
  owner 'root'
  group 'root'
  action :create
end

package 'build-essential' do
  action :install
end

Rationale: specifying the action makes it absolutely clear what is happening without having to check the documentation to see what actions are default. It also makes diffs cleaner, if extra parameters are added later.

MND002: File must end with newline

The last byte of every file in the cookbook must be 0x0a, ASCII newline. This is because certain tools behave oddly if a trailing newline is missing, and all good editors should include one by default.
