Tool authoring methods

Choose how you author a custom tool before testing and publishing.

Copilot-generated tools

Dev Studio Copilot drafts Python handlers from a natural-language spec.

Copilot scaffolds need review before production. Write a clear tool description — agents use it to decide when to call the tool.

Use manual coding when Copilot or a predefined integration is not enough. See the full tool contract and example on the Custom tools page.

Method	Best for
Copilot	Quick CRUD wrappers, prototypes
Manual	Complex rules, compliance-sensitive logic
Both	Generate scaffold, then hand-edit before publish
