Skills

A skill captures a way of working you would otherwise retype — "cite every claim", "write emails in our house tone", "summarise into decisions and action items" — and applies it to your chat with two keystrokes. Type / in the composer to switch skills.

Launch

What is a skill?

A skill has three parts:

• A name — how you pick it in chat. Letters, digits, hyphens and underscores, no spaces.
• A description — when GreenPT should use it, shown in the skill switcher to help you pick.
• Instructions — what the assistant should do, written in Markdown: headings, lists, emphasis, links, and tables all work.

Your skills live on the Skills page, reachable from the sidebar. Each card shows the skill's name, its description, and an on/off switch.

Creating a skill

From Skills, choose New skill. Beyond the three fields, the editor helps you along:

• Auto-generate drafts the description from the name you typed.
• Improve with AI rewrites the name, description, and instructions together once all three have content.
• Try it before saving runs your instructions against a real prompt in a test panel, so you see the skill's effect before it exists. Test runs are temporary and never saved to chat.

A skill is on from the moment you create it.

The GreenPT catalog

Ready-made skills — among them web research, slide decks, data analysis, meeting notes, email writing, and document summaries — appear alongside your own on the Skills page, marked From GreenPT. Enabling one makes it your own copy under the same name, fully editable like any skill you wrote yourself.

Using a skill in chat

Type / in the composer to open the skill switcher, filter by typing, and pick with Enter — or choose Skills from the + menu. The chosen skill shows as a chip above the composer and applies to every message you send, across conversations, until you clear it from the chip or pick another. The switcher's first entry, No skill, returns to the default assistant behavior.

The reply's steps show when the skill triggered. If the skill is gone by the time you send — deleted or switched off — the answer arrives without it and the steps say so; the message never fails because of a missing skill.

On, off, and delete

The switch on a skill's card takes it out of the switcher without losing anything — flip it back on whenever you want. Deleting, from the skill's editor, is the permanent action: it cannot be undone, and it frees the name for a fresh start. Conversations that used a deleted skill keep working without its instructions.

Frequently asked questions

Can I use two skills at once?

No — one skill applies at a time, and picking another replaces it.

How is a skill different from a Space?

A Space holds persistent context for a body of work — background, guidelines, documents — and one is active at a time. A skill is a compact, reusable way of working that you switch per conversation or per message. They complement each other: a Space knows what you are working on, a skill knows how you like it done.

Can I use my skills through the API?

Yes — the same skills resolve on API chat completions, and skills you create through the API appear in the app.
