" summary

A small linter plugin is built that extends the TypeScript Language Service by overriding language-service methods, walks the AST and enforces the concrete rule that any variable name starting with "is" must have a boolean value, reporting errors when assigned non-boolean expressions. It runs inside the TS server, installs via npm/yarn/mpn link and plugs into tsconfig plugins, works in VS Code/Atom/Vim because it runs at compiler level, and offers hooks for quick fixes; source on GitHub.
