Anthropic donates Agent Skills standard; OpenAI unveils Intelligent UI; Gemini Gems transition to skills.
The AI skills landscape saw significant standardization efforts this week, alongside new platform features and ongoing model transitions.
New here? The 60-second primer
Skills are packaged expertise you install into an AI assistant: Claude Code has skills and plugins (from Anthropic's directory and open git marketplaces), ChatGPT has custom GPTs (the GPT Store), and Google's Gemini has Gems (shareable custom experts). Every rank below comes from captured data — official install counts, GitHub star growth, and the GPT Store's own trending list — not from opinion.
The week
This week, the AI skills ecosystem saw notable structural shifts and new feature rollouts. Anthropic recently donated its Agent Skills standard to the Agentic AI Foundation (AAIF) at the Linux Foundation, a move highlighted in O'Reilly's November 3rd trends report and by AgenticSkills on November 9th [2, 7].
This aims to foster broader adoption and development of agent skills across platforms. OpenAI introduced "Intelligent UI," enabling ChatGPT to generate its own user interfaces in response to user queries [2].
Meanwhile, Google's Gemini Gems are transitioning to a more unified "Skills" format for personal accounts this month, with Workspace accounts following in 2027 [15, 16]. Anthropic also released "Claude Dashboards" for live data visualization and "Claude Mods," a plugin for Claude Code that allows modification of its behavior and user interface [2].
The broader industry is seeing a convergence in agent definitions, with major vendors like Google Cloud, IBM, and Microsoft now describing AI agents consistently as software that plans, uses tools, acts, and checks its own results [3]. Data from Skillselion as of November 8th shows the AI coding-agent tool catalog tracking over 82,000 tools, with a heavy emphasis on the 'Build' phase of development [1].
Pattern watch
A clear pattern emerging this week is the push towards standardization and interoperability within the AI agent skills ecosystem. Anthropic's donation of its Agent Skills standard to the Agentic AI Foundation marks a significant step towards a more unified approach, allowing skills to be more portable across different AI platforms [2, 7].
This is complemented by a growing consensus among major vendors on the definition and protocols for AI agents, as reported by Mean CEO's Blog [3]. The transition of Gemini Gems into a more generalized "Skills" format further underscores this trend, moving away from platform-specific functionalities towards a more integrated skill layer [15, 16].
Try this week
To explore the evolving AI skills landscape, consider trying Claude Code. You can install it on macOS, Linux, or WSL by running `curl -fsSL https://claude.ai/install.sh | bash` in your terminal.
For Windows PowerShell, use `irm https://claude.ai/install.ps1 | iex` [4]. Once installed, you can begin experimenting with Claude Code plugins and its new Mod capabilities to customize your coding assistant experience [2, 9].
