# Tools

**Tools** are the custom actions your app can run: create a record, call an API, calculate something, trigger a side effect. The AI writes them as secure functions and they run against the project you have selected.

Tools belong to the app blueprint and are available in every project of that app. You can limit which roles may use them, and you can require approval before sensitive actions run. Some tools are meant for the AI in chat; others are meant for pages and forms behind the scenes.

Tool parameters can use common formats such as email, phone, URL, date, datetime, and UUID. GenieForge checks those values before the tool runs. If a form submits to that tool, matching field types get the same checks in the browser.

Find them under **App Blueprint → Tools**.
