Editorial, Gallery, Nocturne, Folio and Cobalt styles are scoped to starter templates. Review installation, then Install to staging in the CMS.","plugins":"Plugins are built by an agent for the human's needs and owned in the human's repository. No third-party plugin installation or marketplace is planned. Settings → Brand & themes → Plugins currently offers reading progress and image zoom as built-in examples, disabled by default and applied to staging. A dedicated agent plugin-authoring workflow is not yet implemented; repository code changes follow the existing schema, testing, review and publishing contracts.","bundles":"Themes imports/exports .tar.gz design bundles. Applying overwrites listed paths on staging. Content and uploaded media are opt-in export additions; a base theme is not a full backup."},"starterRules":["Preserve existing homepages; refuse conflicting collections, templates, page URLs and redirects. Review a fresh plan after concurrent edits.","Examples and introductory copy are English in every selected locale. Included examples are Ready: replace or translate them and supply contact links before publishing.","No form processing, bookings, payments, MLS/IDX feeds, maps or property search/filter UI is installed."],"agentWorkflow":["Read get_site, get_schema, get_settings and list_changes before adapting an existing design. Preserve field names and human-editable content.","Use set_brand, write_template, write_part and content-type tools within their advertised scope. Inspect existing source through repository access before replacing a template.","There is no MCP starter-install or theme-bundle import/export tool. Direct the owner to the CMS or use scripts/apply-starter.mjs from a checkout, beginning with --dry-run.","Validate every affected template, inspect the staging build and CMS fields, then review all pending changes.
