Matt Pocock

Matt Pocock called /show-me "a phenomenal skill" on September 3, and the reason it lands is narrow and real: it is a style guide, not a generator. It gives a coding agent a menu of compact visual formats — ASCII component trees, call stacks, mermaid state diagrams, annotated diffs — and tells it to pick one instead of writing three paragraphs.

Operation Bluebird's twitter.new went live, claiming Musk's X abandoned the Twitter name. The highest-engagement reply to the news wasn't about the lawsuit — it was "the most vibe coded piece of junk homepage I've ever seen." explainx.ai fetched the real site and checked the accusation against the actual copy and markup.

On August 18, 2026, Arcads co-founder Romain Torres open-sourced Marketing OS — a single Claude skill structured as six subagent roles that hand work to each other, from positioning down to Product Hunt launch day. explainx.ai breaks down what's actually new here: not the marketing tasks, but the handoff pattern.

You don't need Pangram or a TF-IDF classifier to catch most AI-generated text — you need to know what to look for. Here are the ten tells that show up most consistently across ChatGPT, Claude, and Gemini output, from the em dash to the "it's not just X, it's Y" construction, with real examples and the honest caveat that every single one has false positives.

Ask an AI coding agent for a diagram and you almost always get the same thing back: rounded boxes, default colors, auto-layout arrows, no relation to your site or your argument. That's Mermaid slop — AI slop's diagram-shaped cousin — and it has a name now because enough builders got tired of it to build alternatives.
