AI skills — packaged instruction sets that teach tools like ChatGPT, Claude, or Gemini how to perform specific tasks — are gaining traction among everyday users. Alex Choroshin runs Skills IL, a library of over 200 skills designed for Israeli users, allowing workflows to be reused without writing lengthy prompts each time. These skills are stored in files like SKILL.md and cover everything from routine processes to specialized knowledge domains.
However, the spread of AI skills also introduces security concerns. Researchers testing large organizations found that API keys and access tokens were often stored inside skill packages for convenience. AI agents powered by these skills can access corporate folders, internal systems, and files, opening new attack surfaces. Attackers can hide harmful instructions inside readable text, making detection difficult. Security teams now need to protect every endpoint where an agent operates, not just developer machines.
On the corporate front, Palantir Technologies stands to benefit as AI infrastructure costs decline. Unlike competitors still running pilot programs, Palantir already has AI deployed in production. Seeking Alpha rates the stock a Strong Buy based on this advantage.

How to create AI skills that save time on daily tasks
AI skills are packages of instructions that teach tools like ChatGPT, Claude or Gemini how to do a specific task. They can cover process tasks or specialized knowledge and are stored in files like SKILL.md. Alex Choroshin runs Skills IL, a library with over 200 skills for Israeli users. Skills let you reuse a workflow without writing a long prompt each time.
AI agents can activate hidden capabilities and risk company data
AI agents used by employees can access files, corporate folders and internal systems, creating new security risks. In tests at large organizations, researchers found API keys and access tokens stored inside skills packages for convenience. Attackers can hide harmful instructions inside readable text, making threats hard to detect. Security must now protect every endpoint where an agent operates, not just developer computers.
SK Group proposes Korea-Japan AI task force for semiconductors
Chey Tae-won, chairman of SK Group, proposed a joint AI task force with Japan during a meeting on Oct. 17. The goal is to boost the competitiveness of the Korean semiconductor industry and reduce costs. The task force would focus on AI technology for next-generation semiconductors. The proposal is seen as a positive step despite ongoing trade tensions between the two countries.
NEAR plans AI-assisted formal verification for protocol security
NEAR Protocol plans to use AI-assisted formal verification on its protocol and core smart contracts. NEAR AI reported solving 672 PutnamBench mathematics problems at a submission-time model cost of $111.85. Formal verification aims to prove that software follows defined rules. The approach complements testing and code review but only guarantees the specific properties being checked.

Meta says Claude AI tool caused No Kings Instagram suspension
Meta Platforms said an automated security system mistakenly suspended the Instagram account of the No Kings Coalition during a series of nationwide demonstrations. An AI tool from Anthropic called Claude was accessing profiles at about four times the normal rate, which triggered the security system.
