## Outline

1. Read `docs/skills/catalog.md#feature-composition-explorer`.
2. Identify required capabilities and map them to projects/features using maps and extension-point catalogs.
3. Include required dependencies and flag optional provider choices separately.
4. Check external package/version compatibility signals using existing maps.
5. Produce a minimal proposed feature set and list unresolved identifiers or configuration questions.
6. Hand off to `elsa-cshells-appsettings` only after feature identifiers and appsettings inputs are clear.

Do not guess feature IDs.
