Skills overview
Skills are tools your AI agent can use during a call to take real actions — check a calendar, send an email, update a CRM, call an external API, or hand a question to another GPT assistant. When a skill is configured, the agent decides on its own when to trigger it based on the conversation and your prompt instructions.
How skills work
- You add one or more skills to an agent from the Instructions tab.
- Each skill becomes a tool the model can call during the conversation.
- When the agent detects the need (e.g. "book a meeting"), it triggers the skill with the parameters it gathered from the caller.
- Fonema runs the action and returns the result back to the agent, which continues the conversation naturally.
Always mention your skills in the agent's prompt instructions so the model knows when and how to use them.
Create a skill
- Open your agent profile.
- Go to Instructions → Edit agent.
- In the Skills panel (right side), click + Create skill.

A side panel opens with the available skills. Pick one and configure it.

Available skills
| Skill | What it does |
|---|---|
| Schedule events in Google Calendar | Check availability and schedule meetings on a connected Google Calendar. See Google Calendar. |
| Send email | Send an email automatically during or after a call. |
| Update object in HubSpot | Create or update an object (e.g. a contact) in HubSpot. |
| API call | Call any external API with custom URL, headers, authentication, and parameters. See API Call. |
| Call to GPT | Hand a sub-task or question to another GPT assistant. |
Recommendations
- Add only the skills the agent actually needs — fewer tools means more reliable triggering.
- Describe in your prompt when the agent should use each skill.
- Run test calls to confirm the agent triggers skills at the right moments.
