I just started doing this sort of thing recently.  Here's a snippet from 
my ~/.zshrc:

cd() {
    if [[ -x .autodir/exit ]]; then
        print -- '(-autodir)' >&2
        source .autodir/exit
    builtin cd $@ || return $?
    if [[ -x .autodir/enter ]]; then
        print -- '(+autodir)' >&2
        source .autodir/enter
