Input gating: why a good skill asks before it answers

The single design choice that separates infrastructure from a prompt — and why a refusal to start is a feature.

The most useful thing a skill does often happens before it produces anything at all: it stops and asks you for what it needs. This feels like friction. You wanted output, and instead you got a list of questions. But that pause — input gating — is the single feature most responsible for the difference between AI output that is specific and useful and AI output that is generic filler.

The mechanism

What input gating is

An input-gated skill refuses to start until it has its required inputs. Ask it to write a procedure page and instead of immediately generating, it responds: what is the procedure, the practice name, the primary keyword, the provider's experience, the target reading level? Only once you have answered does it proceed.

Compare that to an ungated prompt, which starts generating the instant you hit enter — filling every gap you left with an assumption. You did not say which city, so it picks a generic one. You did not give a provider's credentials, so it writes around the absence or, worse, invents some. The output looks complete, but it is built on guesses.

An ungated prompt fills every gap you left with an assumption. A gated skill asks instead of guesses.
Why it produces better work

Guesses are where quality dies

Every gap an AI fills with an average is a place the output stops being about you. The practice becomes "a leading clinic," the city becomes "your area," the differentiator becomes a generic platitude. None of it is wrong, exactly — it is just nobody's. And generic is precisely what does not rank and does not convert, because it reads like the hundred other pages that made the same guesses.

Input gating closes those gaps at the source. By forcing the real practice name, the real keyword, the real provider experience into the process before generation starts, it guarantees the output is grounded in your specifics rather than the model's defaults. The questions are not bureaucracy; they are the difference between a draft about your client and a draft about a fictional average one.

The safety dimension

Gating is also a guardrail

In regulated fields, input gating does double duty. A skill that asks for the provider's actual credentials will not fabricate them. A skill that asks for a sourced statistic will not invent a plausible-sounding one. The gate is where a well-built skill enforces "supply this real information or I will flag that it is missing" — which is exactly the discipline that keeps medical and other sensitive content honest.

An ungated tool, by contrast, has no such checkpoint. It will happily produce a confident page full of specifics it had no business inventing, because nothing ever stopped to ask where those specifics came from.

Working with it

Lean into the questions

The instinct, when a skill asks for five inputs, is to answer them as fast as possible to get to the output. Resist that. The quality of what you get back is directly proportional to the quality of what you put in. A thoughtful answer to "what makes this provider credible?" produces a genuinely differentiated page; a one-word answer produces a thinner one. The gate is an invitation to put real information in, and it rewards you for taking it seriously.

If you genuinely do not have an input — a real statistic, a credential, a local detail — the right move is to say so, and let the skill flag it for follow-up. That is far better than supplying something invented just to get past the question.

The takeaway

Input gating looks like friction and is actually the opposite: it is the step that makes output specific instead of generic, grounded instead of guessed, and honest instead of fabricated. A skill that refuses to start without the right inputs is not being difficult. It is doing the most important part of its job — making sure the work is about you.

Specific inputs, specific output

Every MedAuthority skill gates for its required inputs before it runs — so what you get back is grounded in your client, not a generic average.
