You are a personal servant able to provide support and comfort for others. A hallmark of a rogue valet is the ability to be visible only when asked for, able to fade into the background yet be constantly attentive to the master's needs. Servants are ubiquitous in most cultures—this is part of what allows you to hide in plain sight—but very few are valet-rogues.
Not all of this rogue archetype are servants. You may be such things as a batman, butler, coachman, courtier, footman, companion, groupie, lady-in-waiting, maid, paramour, poor relative, squire, or trophy spouse.
Greyhawk The roguish servant is a trope mainly among humans, half-elves, and halflings. Gentlefolk-adventurers often have servants, and the best of them are in this archetype.
At 3rd level, you are capable of providing for the comfort of others through attention and foresight. Mostly, this is a role-playing effect, but when you or an ally takes a short rest and expends Hit Dice to heal, add your proficiency bonus to the number of Hit Points recovered each short rest. You can help others don armor in half the normal time. You gain proficiency with the cook’s utensils. If you already have this proficiency you instead gain proficiency with any one set of artisan's tools.
Starting at 3rd level, you are able to be very unobtrusive (but not actually invisible) when properly attired and acting discreetly. You are able to use Stealth to hide against creatures of the Humanoid type even when you don't have cover or concealment. In most cases, you won't even have to roll to remain unobtrusive. In combat and when a humanoid wants privacy, you must make a Dexterity (Stealth) check normally in order to hide, but you do not need cover to do so.
If you cause a ruckus by attacking or otherwise performing outrageously, you cannot use this ability for one minute. If a humanoid creature sees this and spreads the word, you cannot use this ability again until you have finished a long rest.
Serve a Master
At 3rd level, when you finish a long rest and do not have a master, you can select a creature within 10 feet to be your master. You and the master do not need to see each other, but you must both be aware of the other's existence and willing to enter a servant-master relationship. Either of you can break this relationship when you begin a long rest.
You can use the Help action to assist your master as an action, bonus action, or reaction, and you can do so at a range of 30 feet. You can even assist saving throws in this manner. You need not be capable of performing the action you are assisting, but you and your master must be able to see each other.
You have an intuitive understanding of when your master needs you. As long as your master is within 300 feet, they can call on you simply by thinking about you. You can make a Wisdom (Insight) check DC 10 to have a general idea about why you are being called, this is automatic if it is a routine call, such afternoon tea.
At 9th level, your discretion becomes legendary. You you can cast Nondetection without a material component, but you can only target yourself and your master. You can also cast Mordenkainen's Private Sanctum as a ritual by inspecting and cleaning the area to be protected. You can end either effect as an action. Though these function as magical spells, they are actually effects of your labor, and you have no limit on how often you can use these abilities.
Like Master, Like Servant
At 13th level, when you Serve a Master, you can imitate some of your master's abilities. If you are already have a proficiency there is no additional effect.
- If your master is proficient in a skill, you become proficient in that skill.
- If your master is able to use a certain magic item, you are also able to use that magic item.
Pillar of Strength
At 17th level, as a reaction when within 10 feet of your master and able to see them, you can give your master advantage on any attack roll, ability check, attack roll, or saving throw they are about to make. If your master is within 10 feet of you and casts a spell, you can use your reaction to give that creature disadvantage on its saving throw.

Done for fun, the capable maid is a classic anime trope.
