+//! Skill use cases (ARCHITECTURE §14.2; L12).
+//!
+//! Skills are reusable, model-agnostic workflows (IdeA's universal equivalent of
+//! a CLI slash-command). This module owns their CRUD across both scopes
+//! ([`domain::skill::SkillScope`]) and the agent↔skill assignment that records a
+//! [`domain::skill::SkillRef`] in the project manifest. The actual injection of
+//! an assigned skill's body into the generated convention file happens at agent
+//! activation (L6).
+//!
+//! Every use case talks only to ports ([`domain::ports::SkillStore`],
+//! [`domain::ports::AgentContextStore`], [`domain::ports::IdGenerator`],
+//! [`domain::ports::EventBus`]).
