/**
 * Schema for the YAML frontmatter of a `SKILL.md` file.
 *
 * Claude Code skills are markdown files whose frontmatter declares
 * metadata that governs discovery, invocation, and tool access. All
 * frontmatter fields are optional in Claude Code; `name` falls back to
 * the directory name and `description` can fall back to the body.
 *
 * This schema intentionally stays permissive for Claude Code runtime
 * compatibility. The stricter Agent Skills open-standard constraints
 * (for example lowercase hyphenated names, length limits, and
 * name-matches-directory checks) are better enforced by plugin linting
 * where the file path is available.
 *
 * Note: Claude Code uses kebab-cased keys in some frontmatter fields
 * (`disable-model-invocation`, `user-invocable`, `allowed-tools`,
 * `disallowed-tools`, `argument-hint`). `Schema.Class` preserves the
 * exact key, so the TypeScript properties use the same kebab-case
 * identifier via bracket access.
 *
 * @since 0.1.0
