Voice and format register for PR/code review comments. Use when drafting, suggesting, or editing any pull-request or code review comment on the user's behalf — inline comments, top-level PR comments, review summaries, or replies to review threads.
Use when comparing this dotfiles repo against another repo, tool or framework to decide what ideas to borrow — e.g. "see what's worth stealing from owner/repo", "find inspiration in X", "should we adopt their setup". Also use to re-triage previously spotted improvement candidates.
Register for essays, posts, and long-form prose in the author's voice: plain, warm, concrete, with breath between the hard lines. Use when drafting or editing an essay or blog post; when a draft reads clipped, cold, or relentless; when an editing pass has flattened the warmth out of something; or when the user asks for prose that sounds like them rather than like a style contract.
Review a single UI screen against nine parsing-cost lenses and produce a findings doc ranked by how hard the user works to read the answer, an explicit "don't touch" list, and a risk-phased fix plan. Use when critiquing or auditing an existing or proposed screen, when a UI feels cluttered or buried, before/after a UI build, or when the user says "ux review", "review this screen/page/card", "make this parseable", or invokes /ux-review.
