Customizing a standard subagent within one agent
Key Takeaway
Customizing a standard subagent changes only that agent's copy, in that agent version. Updates in the asset library don't reach that copy automatically, so to get them you add the subagent again and recreate your customizations.
A standard subagent is an out-of-the-box subagent that you add to an agent from the asset library. You can customize it inside one agent so it fits your use case and follows the right guardrails for your business. You can edit its fields, change the order of its instructions, and add or remove its actions. Your changes stay in that one agent and agent version, which matters when you manage several agents or want updates from the asset library.
Permissions and availability
To edit a standard subagent, you need the "Manage AI Agents" permission plus the permissions required for your agent type. The feature is available in Lightning Experience on Enterprise, Performance, Unlimited, and Developer Editions.
