 Keep comments short — one or two lines. Capture only the non-obvious reason (safety constraint, compatibility shim, design-doc rule). Don't restate what the code does, narrate the mechanism, cite design-doc sections verbatim, or explain adjacent API choices unless they're the point.
 
+## Lint Rules: Do Not Disable Max Lines
+
+Never add a `max-lines` disable (`eslint-disable max-lines`, `oxlint-disable max-lines`, or line-specific variants). Split the file, extract focused modules, move fixtures/builders into named files, or otherwise reduce the counted lines instead.
+
 ## File and Module Naming
 
 Never use vague names like `helpers`, `utils`, `common`, `misc`, or `shared-stuff` for files, folders, or modules. They carry zero information and tend to become dumping grounds. Name files after what they _actually_ contain — prefer the concrete domain concept (e.g. `tab-group-state.ts`, `terminal-orphan-cleanup.ts`) over the generic role (`tabs-helpers.ts`, `terminal-utils.ts`). If you find yourself reaching for `helpers`, the file probably has more than one responsibility and should be split, or there's a better name hiding in the code that describes what the functions operate on.
