Call integrations from a skill

A skill script is a skill that includes Python the agent can run in the code sandbox. Use it when a connector exists but its tools alone can’t handle the logic you need, such as branching, batching, or cleaning up results. You don’t need to write the script. Describe the outcome and let the agent draft the skill.

When this helps

Transform results before the next step (filter rows, reshape JSON)
Call the same connector many times with custom logic
Combine two connectors in one deterministic script

If you only need “send this Slack message,” add the Slack connector. Don’t wrap it in a skill.

How to get the agent to write one

Add the connector on the agent first. See Give an agent a connector.
Paste one of the prompts below.
Review the skill. It should use the Gumloop SDK for the connector, not raw HTTP.
Save it and attach it to this agent (and others, if you want).

Example prompts

Copy one of these, then swap in your mailbox, sheet, or channel. Filter unread email into a table

Create a skill that lists unread Gmail from the last 24 hours, keeps only messages from customers (not newsletters or internal @ourcompany.com), and writes a summary table with sender, subject, and a one-line next step.

Batch Slack follow-ups

Create a skill that reads a list of Slack user IDs, posts the same check-in message to each person as a DM, and returns who succeeded and who failed. Use the Slack connector already on this agent. Do not use raw HTTP.

Sheets + Slack digest

Create a skill that reads the "Leads" tab in our Google Sheet, keeps rows where Status is "New" and Score is over 70, and posts a Slack digest to #sales with name, company, and score. Use the Google Sheets and Slack connectors already on this agent.

Retry-safe CRM update

Create a skill that takes a list of Salesforce account IDs, fetches each account, and writes Last_Touched__c to today. Skip IDs that 404. Return a table of updated vs skipped. Use the Salesforce connector, not raw HTTP.

After it writes the skill

Keep the skill focused on one job.
Tell the agent which connector account to use if it has several to choose from.
If the script fails, paste the error back and ask it to fix the skill.
Every edit creates a new version. If a change breaks the skill, open the Edits tab on its detail page to see what changed and download an earlier version.

FAQ

Should every Slack or Gmail action be a skill?

No. Add the connector and ask the agent in chat. Use a skill script only when the connector’s tools alone can’t handle the logic you need, such as branching, batching, or cleaning up results.

The skill used requests / HTTP instead of the connector

Tell it: “Rewrite this to use the Gumloop SDK and the connector already on this agent. Do not call the API over HTTP.”

Can I attach the same skill to other agents?

Yes, after you save it. Those agents still need the same connectors attached.
