-- Resolve context source filenames before installed skill names and show authored content consistently.
-- Install unfamiliar context types as ordinary guidance so providers can introduce new types.
-- Store resolved skill provenance in `SKILL.md` front matter under `metadata`, with `metadata.type: skill` declaring skills.
-- Preserve authored names, descriptions, additional metadata, and the original Markdown body using native front matter AST nodes.
-- Share loaded documents between context and skill installation, and use direct writes with rerunnable progress.
-- Discover dependency guidance through installed Markdown files and the list/show commands. Remove generated indexes and the `agent:context:index` task.
