 ## General Guidelines for working with Nx
 
 - For workspace exploration, use the `nx-workspace` skill when available;
-  otherwise inspect `project.json`, `pnpm nx show projects` and `pnpm nx graph`.
+  otherwise inspect project-local project.json files, `pnpm nx show projects` and `pnpm nx graph`.
 - Run project tasks through local `pnpm nx`, not a global Nx installation.
 - Use the Nx MCP server when available; otherwise use CLI discovery.
 - Check `node_modules/@nx/<plugin>/PLUGIN.md` for plugin guidance when present.

 root imports and local navigation links/anchors, including migration destinations.
 Markdown navigation is parsed with the already-declared `marked` dependency;
 undefined explicit reference links are errors, and code examples are excluded.
+Backticked concrete paths in root guidance and the context map are checked from
+the repository root, including unknown top-level directories and filenames.
+Write generic filenames as prose; commands, templates, globs, URLs, package
+aliases and recognized JavaScript globals are excluded. Use Markdown links for
+ambiguous filenames that resemble code symbols.
 Heading anchors are derived from parsed text, not HTML sanitization. The Nx test
 hash includes `marked` so dependency changes invalidate parser coverage.
 It cannot prove semantic equivalence; review changed contracts as well.
