Draft and edit long-form technical writing - blog posts, engineering write-ups, externally published design docs and ADRs, substantial PR descriptions, long LinkedIn or Substack pieces - so it reads like a senior engineer wrote it rather than a model. Removes AI cadence (em-dashes, "X isn't Y. It's Z." pivots, numbered framing, rule-of-three symmetry, closing synthesis, weakening hedges) and replaces it with patterns drawn from working technical writers (Dan Luu, Marc Brooker, Julia Evans, Simon Willison, Patrick McKenzie, Will Larson, Rachel Kroll, Aphyr). Use when the user asks to "draft a blog post", "write up X", "edit this post", "review my draft", "make this less AI", "fix the AI cadence", "this sounds like ChatGPT", "de-slop this", or shares a long-form technical draft and asks for feedback. Not for short chat messages, code comments or marketing copy.
