Agents and skills
Build reusable AI assistants — saved instructions and capabilities you can use again and again.
Instead of re-explaining what you want every time, you can save a reusable assistant — a name, instructions, and a set of capabilities — and reuse it everywhere. In the NUFI app these live under Skills.
Skills
Open Skills from the left icon rail. This is where your saved assistants live. A new account starts empty ("No skills yet").
You can also reach a skill from the Tools menu (the sliders icon in the message box), alongside File Search, Web Search, Run Code, and Artifacts.
Admin Settings at the bottom of the panel is for administrators — regular users can leave it alone.
Writing good instructions
The instructions are what turn a generic AI into something that feels like a teammate. Be specific:
- Role — "You are a senior support agent for an e-commerce store."
- Style — "Concise. Friendly. No jargon. End every reply with a clear next action."
- Constraints — "Never share personal data. For pricing, link to /pricing instead of stating numbers."
- When stuck — "If you can't answer confidently, say so and offer to escalate."
Keep them short and consistent — long, contradictory instructions make the assistant behave unpredictably.
Giving an assistant extra capabilities
Beyond plain text, an assistant can use the tools in the Tools menu:
- Run Code — runs code in a sandbox. Upload a CSV and ask for an analysis.
- Web search — looks up live information mid-conversation. See Web search.
- File Search — searches the files you've uploaded. See Files and images.
- Artifacts — produces rich, structured output (e.g. a rendered document or app preview).
Give an assistant only the capabilities it needs — fewer tools means faster, cheaper, more predictable behaviour.
Sharing
What you can share, and with whom, depends on what your organisation has enabled. Where sharing is available you can typically:
- Share an assistant with specific teammates.
- Share it with a whole team.
- Publish it so everyone in your organisation can find it.
Some deployments include a fuller agent builder with avatars, attached knowledge files, and a marketplace. If you don't see those options, your organisation hasn't turned them on — ask your admin.
When things go wrong
- It ignores its instructions — they may be too long or contradictory. Try shorter, clearer phrasing.
- It uses the wrong tool — turn off tools it shouldn't need.
- Skills are missing entirely — your admin hasn't enabled them for your team. Ask.
