Etiquette
Naming your edges
A short 'nothing about X' is a gift to a judge who would otherwise guess, and it protects you from a clip that hits a nerve you never mentioned.

Say what you do not want in one short line of the brief - "nothing about weight", "no comments on age" - with no justification attached. A single exclusion often helps a judge more than any amount of positive detail, because it shows where the edges are, and it is the line most buyers forget to write.
Why judges need this more than buyers expect
A judge working from a brief with no exclusions has to guess at what might land badly, and guessing under uncertainty produces caution. A cautious clip hedges, avoids anything remotely pointed, and comes back flatter than the register asked for - not because the judge lacked skill, but because nothing in the brief told them where the edges were. One line - "nothing about weight," "no comments on age," "keep it away from comparisons to a partner" - removes that guesswork entirely and lets the judge commit fully to everything that is left. Judges who work regularly with buyers who state limits will say directly that it is the single biggest factor in how confidently they can perform a sharper register.
What a good exclusion line looks like
Short, specific, and stated without justification. "Nothing about X" does the job completely; a paragraph explaining why is not required and often makes the line harder to read at a glance, which is the opposite of what it is for. It sits naturally alongside the register line and the one specific worth naming - together the three make up most of what a brief needs to actually work, in barely more words than a single paragraph. A close cousin of this is asking a judge not to mention a specific topic at all, which works the same way but is scoped to one subject rather than a whole register. The same instinct applies if a stated measurement is part of the brief: taking it properly once removes an entire category of guessing, on top of whatever the exclusion line already ruled out.
The difference between this and negotiating a limit
This is not the same move as stating your limits during back-and-forth with a judge, which is about drawing a line when a request or a register is being discussed and shaped. Saying what you do not want is a preventative line written into the original brief, before there is anything to negotiate - it heads off a problem rather than responding to one that has already come up. Both matter, but they happen at different points in the process and do different jobs.
Why this line gets skipped
Most people who skip it are not being careless; they simply have not thought about what could go wrong, because they are focused on what they want to go right. That is exactly the blind spot the line exists to cover, and it costs nothing to add once you notice it. It is worth treating as standard, the way a register line and a specific are standard, rather than something to remember only after a clip has already missed.
There is also a quieter reason people leave it out: naming a sore point in writing can feel like drawing attention to it. In practice the opposite happens. An unstated worry does not stay hidden from a judge working blind; it just turns into a topic the judge might stumble into by accident, because nothing told them it was off the table. Buyers tend to assume the sore point is more obvious than it is, a pattern Gilovich, Savitsky and Medvec (1998) called the illusion of transparency: people overestimate how far others can discern their internal states. Naming it plainly, once, and moving on is a smaller act of exposure than the accidental version, and it is the one within your control.
There is a version of this worry that is specific to a first commission: not knowing yet what you are sensitive about until a clip has already touched it. That is a real limitation and there is no way to fully brief around something you have not identified in yourself yet. The honest response is not to try to preempt everything, which produces an exhausting list nobody wants to read, but to write down the one or two things you already know matter and trust that a professional judge, told nothing more, will still stay well clear of anything obviously risky by default.
This is also one of the clearer places where a human review and an automated one diverge in what they can even offer. A scored read has no way to honour an exclusion, because it is not choosing what to mention - it returns a fixed structure regardless of what you would rather it skip. An AI-generated commentary is closer but still limited, tuned by settings rather than a genuine read of a written line. A person can simply be told, and will simply comply, which is a real advantage of paying for a person specifically - one Rate Cock's own comparison touches on when weighing the two options against each other.
