50+ customizable Claude skills just dropped

Good morning. It’s Wednesday, December 24th.

On this day in tech history: In 1965, Daniel Bobrow's STUDENT program solved high-school algebra word problems in natural language, parsing ambiguous English into Lisp equations. This early NLP feat handled units and context, influencing symbolic reasoning systems. An underappreciated gem in bridging human language to formal computation, predating modern semantic parsers.

How could AI help your business run smoother?

Most business owners can point to at least a few processes and think, “AI could probably handle this.” The problem is knowing how to do it safely, correctly, and without disrupting operations. Data Rush does exactly that. We design and build custom AI solutions that automate admin work, organize data, and deliver real efficiency gains. Start with a free consultation to see where it makes sense—and where it doesn’t.

50+ customizable Claude skills just dropped

A subtle but powerful resource just landed for anyone serious about leveraging Claude at scale. A new GitHub repository has dropped with over 50 ready-to-customize "Claude Skills," essentially structured workflows that train Anthropic's AI to execute specific tasks consistently and on demand.

These skills span nine practical categories: Document Processing (Word, PDF, PowerPoint), Development Tools (Playwright, AWS, Git), Data Analysis, Business & Marketing, Communication, Creative Media, Productivity, Project Management, and Security. Each one lives in its own folder with a clear SKILL.md file laying out the prompts and logic.

You can load them directly in Claude.ai via settings, drop them into Claude Code's config, or hook them up through the API. The whole repo is Apache 2.0 licensed and openly welcomes contributions. As Claude Skills become a de facto standard for structured AI workflows, this repository offers a practical toolkit for anyone looking to operationalize AI beyond basic prompts. Read more.

GPT-5 cracks elegant math as OpenAI wrestles with unpatchable prompt exploits

A paper by Swiss mathematician Johannes Schmitt reports that GPT-5 independently solved a long-standing open problem in enumerative geometry, producing a novel inequality proof by drawing on non-obvious techniques from algebraic geometry.

The work was conducted in a multi-model workflow: Gemini 3 Pro handled boundary cases, Claude assisted with exposition, and formal verification was completed in Lean using Claude Code and ChatGPT 5.2. Schmitt published full prompts, transcripts, and authorship labels, a new norm for transparency in AI-assisted mathematics.

Meanwhile, OpenAI is staring down a colder truth about agentic systems. With tools like ChatGPT Atlas that browse and act on the web, prompt injection attacks may never be fully eliminated. Admitting there may never be a perfect fix, the company’s response includes: stack defenses deep, patch fast, and train an RL-powered automated attacker to red-team exploits before release. Security researchers continue to advise constrained permissions and breach-first assumptions.

OpenAI also just launched "Your Year with ChatGPT." This Spotify-Wrapped-style recap delivers personalized themes, stats, awards, poetry, and images for users with memory enabled. SoftBank meanwhile is reportedly racing to raise $22.5 billion by year's end to meet its commitment to OpenAI's Stargate. Masayoshi Son has already cashed out the full Nvidia stake, trimmed others, and locked down spending. Read more.

Google is steadily building a deeper AI moat

Gemini 3 has now outperformed rivals including ChatGPT on speed, reasoning, and benchmark coverage, leading 19 of 20 major tests and setting a new high on Humanity’s Last Exam, a benchmark designed to approximate near-human reasoning. The jump has drawn rare public praise from figures such as Geoffrey Hinton and Marc Benioff, fueling the view that Google may be regaining a dominant position in frontier AI.

The advantage runs deeper than models. Cloudflare data shows Google’s AI crawlers see more than three times as much of the web as OpenAI’s, a byproduct of Google Search acting as the internet’s default gateway. That imbalance is now attracting regulatory scrutiny, with the UK’s CMA considering whether Google should be forced to split its search and AI crawlers to prevent data dominance from spilling into model training.

Infrastructure is the other lever. Alphabet’s $4.75 billion acquisition of Intersect Power, plus assumed debt, secures co-located renewable energy and data center projects projected to deliver 10.8 gigawatts by 2028. The strategy is designed to bypass grid bottlenecks and lock in power at a scale few competitors can match.

Distribution is moving just as fast. Gemini 3 is being embedded directly into YouTube through Playables Builder, letting creators generate games from simple prompts. At the productivity layer, Google is testing a new “Lecture” mode in NotebookLM, capable of generating 30-minute, single-voice audio lectures that connect and explain dense source material.

Language selection is built in, and new narration options, including British English voices previewed in partnership notebooks, are slated for 2026. Google isn’t just chasing the AI race anymore. It’s trying to own the terrain. Read more.
