check-conventions

Checks a change, such as a pull request, a branch or the working tree, against the rules a writer can miss, which are the project's conventions under .claude/rules/conventions/, the common pitfalls, every rule of the laminar code-style skill marked narrower than the book, and its conventions files for the languages of the change. Use when the user asks for a convention check, asks to check a change against the team or project conventions, or asks for a convention check before a merge. Every finding names the rule it rests on, and a finding is input to a discussion, not a gate on the merge. It checks the patterns of the book among the common pitfalls and the few design directions of the book that the review skill of the laminar plugin does not judge yet, and leaves every other design direction of the book Laminar Software Design to that review skill, which judges them.
