Investigator (Spiritualist) – Whispering Spirits: is there an action requirement?

[Secret Wizard]

For context:

Whispering Spirits:

Whispering Spirits (Su): At 4th level, the spiritualist can open a conduit with the spirit world that can aid him in combat for a short time. He can expend one use of his commune with spirits ability in order to gain an insight bonus to both AC and saving throws equal to his Wisdom modifier (minimum 1) for 1 minute. This ability replaces swift alchemy.

Is there an action requirement for this?

The Commune With Spirits ability has a 1 minute casting time for some spells, but I don't think this ability was intended to have a 1 minute preparation time before combat, nu? Seems like a free/swift action, or a move at most was the intention.

Given all the ACG editing issues, I think a clarification would be in order.

Commune with Spirits:

Commune with Spirits (Sp): Instead of relying on alchemical research to find clues, a spiritualist relies on communion with the world beyond death. At 1st level, a spiritualist gains the ability to use comprehend languages, detect secret doors, and identify, but each has a casting time of 1 minute, as the spiritualist needs to consult with the spirits of the dead that dwell in his area or that are somehow attached to him in some way. The spiritualist can use this ability a number of times per day equal to his investigator level + his Wisdom modifier.

Supernatural Abilities (Su): Using a supernatural ability is usually a standard action (unless defined otherwise by the ability’s description). Its use cannot be disrupted, does not require concentration, and does not provoke attacks of opportunity.

It's a standard action, you just lose a use of your commune with spirits ability, you're not using it.

If the ability said

Then it'd be the default 1 minute that commune with spirits is.

Yeah it's a standard as default. And lasts a minute.

The general rule is that if an action is not listed it defaults to a standard - don't recall where that is listed. I'll see if I can dig it up, unless someone beats me to it.
