Write the guidance once, not in every assistant

Skills

Playable below - no signup

Every team ends up with the same paragraph pasted into six assistants: how we write, what we never promise, which checks a draft has to pass. A skill is that paragraph made into an object — versioned, shared with the groups you choose, and pulled in only when it is relevant.

Open a skill and read what is in it

Six sample skills: a house writing style, tender triage, an incident write-up format, Dutch business correspondence, a contract-review checklist and a weekly digest. Edit one — nothing is saved.

Sample skills only. The demo has no network access, so edits are discarded on reload.

What a skill holds

Four parts, and the third is the one people skip

Instructions

The prose an assistant reads before it answers. Written once, in one place, so correcting it corrects every assistant that uses it.

Rules

Short, checkable constraints — no exclamation marks, never promise an unconfirmed date. Rules are where a house style stops being a suggestion.

Worked examples

An input and the output you wanted. This is the part teams leave empty and then wonder why the tone drifts — a model matches examples far more reliably than it follows adjectives.

When to activate

Keywords that make a skill load only when the conversation is actually about that work, so an assistant is not carrying six irrelevant rulebooks into every reply.

Shared to a group, not to everyone

A skill starts personal. Publish it to a group and the people in that group get it — support gets the tone rules, legal gets the clause checklist, and nobody inherits guidance written for someone else’s job. The permission model is the same one the rest of the workspace uses, so there is nothing new to administer.

Why this is not just a longer prompt

A long prompt is copied, and copies drift. Six assistants with the house style pasted in become six slightly different house styles within a quarter, and nobody notices until a customer does. Making it an object means there is one to change, one to review, and one to point at when someone asks why the wording is what it is.

FAQ

Worth knowing

How is a skill different from a knowledge base?

A knowledge base is material the assistant reads to find facts. A skill is guidance on how to behave — tone, format, what to check before answering. Most useful assistants have both: the knowledge to answer, and the skill to answer the way you would.

Can an assistant use more than one?

Yes, and most do. Activation keywords keep it sane — a skill loads when the conversation is about that work rather than being carried into every reply.

Who can edit them?

Whoever you share them with as an editor. Because a skill is shared rather than copied, an edit reaches every assistant using it, which is the point and also the reason to be deliberate about who holds the pen.

Write one and see how far it travels

Start with the paragraph you have already pasted into three assistants. That one is always the best first skill.
