Well, I've never seen one myself, so I guess i can't prove or disprove that.

But ninjas use disguises as often as creeping along in shadows (if not more often) to hide, so there's no reason not to put on a disguise, even if you plan on not being seen.

From the PPC Manual, Volume 4, Chapter 2, emphasis added:

"The reason for the Disguise Generator is simple. It is against PPC policy to interfere with the Canon worlds more than necessary -- to do so would only cause more work for us. Thus, Agents disguise themselves as races from the Canon -- as elves, orcs, generic human wizards, and so forth. If possible, it is recommended that the disguise chosen is of something that would reasonably perform the actions the Agent is undertaking -- for example, killing a member of the Fellowship of the Ring -- but it is appreciated that this is not always viable, and violations of this rule are usually overlooked."

That is the original reason for disguises, and why Jay and Acacia usually went as orcs. So, unless you plan to stick exclusively to continua full of humans from your character's era/style of dress, the answer is yes, even a ninja has to go in disguise, even if it's just clothes.

I think that Agents in bad slash don't use disguises much, because they usually only have canon characters to dealt with. The canon characters won't see or hear an Agent unless the Agent does something really loud/noticeable. The Somebody Else's Problem field generator in the flash patch keeps them from noticing the Agents. However, the Agents are a Mary Sue's problem, so the Sues can see and hear the Agents. The disguises keep the Sues from recognizing the Agents for what they really are.

At least that is my understanding of it.

"Other Common Mission-Related Questions

Where should I post my completed missions?

It’s up to you. Livejournal is a common choice, but if you have your own website, feel free to put it there. You can also post directly to our LJ community. FanFiction.Net (known around here as The Pit) is an option, but we don’t suggest it, as the admin is very likely to remove PPC-style stories.

Wherever you choose to post, make sure you link us to it. Post a link on the Board, and if you use your personal livejournal, a link post on the community would be very much appreciated for ease of access and archival purposes. Also, many agents have permanent links to all their missions on their profile pages here on the Wiki. We highly recommend doing this."

I think the disguises are just to make things easier. I mean, as far as I can tell, it keeps them from having to neuralyze anyone that happened to see them. In one of the TOS, Agents Sean and Lux tagged along, undisguised. This would lead me to assume it is possible. But, as you of all people know, I've been here for a shorter time than you. Thankfully, I tend to absorb information like mad (whether that is healthy or not). Anyway, my two cents are in.

P.S. Just came across info stating that most missions end with neuralyzations anyway at this point, due to the massive twisting of the canon. That would lead me to assume that the disguises are more to make things easier than anything else.
