- ai-ugc-ad-videoNewhashgraph-online/awesome-codex-pluginsOpen-source alternative to Arcads: AI UGC ads with an AI actor holding your real product. Casts a creator whose age matches the claim in the room where the problem happens, writes a phone-real script (a yapper, unboxing, street interview or in-car take) with every line in the prompt, locks the face, the voice and the product label across shots, prompts camera flaws and breaths so it doesn't look waxy, generates on Seedance 2.5, Kling 4 or Creatify through varg, and labels it. It never puts a first-person testimonial or result in an AI mouth (FTC rule) and never targets TikTok Shop presenters (AI voices banned there). Use when someone wants AI UGC ads, an AI creator or actor talking about their product, Arcads/Creatify/MakeUGC-style ads, or UGC without hiring creators. NOT for TikTok Shop affiliate videos (use tiktok-shop-video), product-only shots with no person (use product-photo-to-video), or the same characters across a multi-scene story (use varg-consistent-characters).MediaNo warnings★ 1.5K↓ —

- generate-ppmpluginmicrosoft/power-platform-skillsBuild and verify a third-party `.ppmplugin` end to end. This recommended entry point detects Android and iOS source, confirms target platforms, then invokes the manifest, platform build, assemble, and audit stages in order. Advanced users can invoke a stage directly for focused reruns or debugging. Produces a native-only bundle (`manifest.json` plus an Android DEX and/or iOS framework) and stops on any failed stage rather than emitting an unverified partial build. Run after the native module exists.EngineeringNo warnings★ 1.1K↓ —

Also trigger for questions about Annex A.1 (controller controls), A.2 (processor controls), A.3 (shared security controls), or implementing a standalone PIMS without ISO 27001. When in doubt, use this skill — it covers the full ISO 27701 lifecycle from gap assessment through certification.SecurityNo warnings★ 1K↓ —

gate-check
undefined-ui/second-brain-os
From the author
Find the decisions in a pipeline that do not need the expensive model and propose the gate for each: a rule, a classic classifier, or a small model, with fail-closed routing. Use when the user asks to cut model costs or latency, says the big model handles everything, or wants a triage / routing / filter layer in front of an agent. Analysis plus an optional baseline scaffold. Do NOT use for auditing context layout (context-audit) or for building eval suites (evals-bootstrap).
