Write a scenario, step by step ↗How sub-agents work ↗

Make the example yours.

These XML files are documentation downloads only. Reading or downloading one does not install it, execute it, or add it to the Lilith source archive.

Start with the bundled Scenarios directory from Lilith V3. Copy that matching catalog to a trusted editable folder and add your example XML alongside it. Keep the filename equal to its scenario ID.

Point LILITH_SCENARIOS_ROOT at that folder before starting Lilith. A custom root replaces the bundled catalog rather than merging with it, so keep the bundled files you still need, including greeting.xml for startup and scheduled greetings. Then ask Lilith to run the scenario by name and supply its required values.

Saved XML is trusted application content. Embedded C# executes with the host's permissions and requires the .NET SDK; it is not sandboxed. Workspace and scheduling operations keep their selected version's access and approval rules. Examples are authored against the documented contract; they are not live model execution guarantees.
