You've probably seen the headline: "Show HN: I processed 100k+ LinkedIn posts into open-source Claude Code skills." It sounds like something for career coaches, but it's actually a great reason to talk about how AI tools help save on subscriptions and why reliable virtual cards are needed to pay for them.
What Are These Skills?
A developer analyzed over 100,000 LinkedIn posts and created 11 ready-to-use skills for Claude Code and Codex. These skills help write posts that sound human, craft comments that get noticed, analyze your feed, and build a publishing cadence. Everything is open source and available on GitHub.
Essentially, these are pre-built prompts and scenarios that automate content creation routines. Instead of spending hours thinking about a post, you run a skill and get a draft that only needs minor editing.
Why Does This Matter for Virtual Card Users?
There are two sides to this.
First — savings. Many AI-based tools (like Claude Pro, ChatGPT Plus) require a subscription. If you actively use such services, a virtual card with flexible limits is your way to keep expenses under control. You can set a limit for a specific service and not worry about overspending.
Second — accessibility. Some AI services don't accept cards issued in certain countries. Virtual cards, especially those issued in suitable regions, solve this problem. Plus, if a service doesn't support 3DS, some transactions may be declined — but with a proper virtual card, such surprises are less likely.
How Does This Work in Practice?
Imagine you're a freelancer or small business owner who uses LinkedIn to attract clients. Previously, you spent hours on posts; now you use open-source Claude skills. But for that, you need a Claude subscription (or API access). You can pay for it with a virtual card linked to your account. The key is to choose a card with 3DS support and reasonable limits.
If the card doesn't go through, typical reasons include: incorrect issuing region, insufficient funds, or restrictions on international transactions. With VirtCardPay virtual cards, such issues are usually absent: they are issued in the right regions and support 3DS.
Conclusion
AI tools like these skills are not just hype but a real way to simplify work. However, to use them without headaches, you need a reliable payment method. Virtual cards are not only about security but also about accessing global services without unnecessary barriers.
