+### Skills (`_skills.py`)
+
+- **`Skill`** - A skill definition bundling instructions (`content`) with metadata, resources, and scripts. Supports `@skill.resource` and `@skill.script` decorators for adding components.
+- **`SkillResource`** - Named supplementary content attached to a skill; holds either static `content` or a dynamic `function` (sync or async). Exactly one must be provided.
+- **`SkillScript`** - An executable script attached to a skill; holds either an inline `function` (code-defined, runs in-process) or a `path` to a file on disk (file-based, delegated to a runner). Exactly one must be provided.
+- **`SkillScriptRunner`** - Protocol for file-based script execution. Any callable matching `(skill, script, args) -> Any` satisfies it. Code-defined scripts do not use a runner.
+- **`SkillsProvider`** - Context provider (extends `BaseContextProvider`) that discovers file-based skills from `SKILL.md` files and/or accepts code-defined `Skill` instances. Follows progressive disclosure: advertise → load → read resources / run scripts.

 ### Workflows (`_workflows/`)
 
 - **`Workflow`** - Graph-based workflow definition
