Actions return a status like condtions, so can be followed by more conditions or actions.
Most actions (like -prune) return a true.
The default operator is -a (logical "and") and has higher precedence than -o (locical "or").
You can write your example as
Code:
find . \( -name 'secret' -a -prune \) -o -print

The right side of an "and" is only executed if the left side is true.
The right side of an "or" is only executed if the left side is false.
Applied to your example:
If the -name 'secret' is true then the -prune is executed and gives true, so the parenthesis part is true, so the -print is not executed.
If the -name 'secret' is false then the parenthesis part is false, the -prune is skipped, the -print is executed.

NAME
find - search for classes and objects SYNOPSIS
itcl::find option ?arg arg ...? _________________________________________________________________ DESCRIPTION
The find command is used to find classes and objects that are available in the current interpreter. Classes and objects are reported first in the active namespace, then in all other namespaces in the interpreter. The option argument determines what action is carried out by the command. The legal options (which may be abbreviated) are: find classes ?pattern? Returns a list of [incr Tcl] classes. Classes in the current namespace are listed first, followed by classes in all other names- paces in the interpreter. If the optional pattern is specified, then the reported names are compared using the rules of the "string match" command, and only matching names are reported. If a class resides in the current namespace context, this command reports its simple name--without any qualifiers. However, if the pattern contains :: qualifiers, or if the class resides in another context, this command reports its fully-qualified name. There- fore, you can use the following command to obtain a list where all names are fully-qualified: itcl::find classes ::* find objects ?pattern? ?-class className? ?-isa className? Returns a list of [incr Tcl] objects. Objects in the current namespace are listed first, followed by objects in all other names- paces in the interpreter. If the optional pattern is specified, then the reported names are compared using the rules of the "string match" command, and only matching names are reported. If the optional "-class" parameter is specified, this list is restricted to objects whose most-specific class is className. If the optional "-isa" parameter is specified, this list is further restricted to objects having the given className anywhere in their heritage. If an object resides in the current namespace context, this command reports its simple name--without any qualifiers. However, if the pattern contains :: qualifiers, or if the object resides in another context, this command reports its fully-qualified name. Therefore, you can use the following command to obtain a list where all names are fully-qualified: itcl::find objects ::* KEYWORDS
