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
The AI agent skills ecosystem saw notable growth this week, with the Skillselion catalog reporting a total of 82,147 AI coding-agent tools and 164 million combined installs as of August 30. This expansion coincides with a doubling of demand for AI skills in cybersecurity job postings across G7 countries over the last year, with 28.5% of postings between October 2025 and March 2026 requiring AI expertise.
Community-driven developments also gained traction, including the 'Superpowers' skill/plugin, which has garnered approximately 40,000 stars on GitHub for its ability to consolidate the entire development process. Another highlighted skill, 'Karpathy Behavioral Rules,' translates common AI agent failure patterns into actionable rules.
For general users, popular prompt patterns like the 'Act As prompt' and 'Prompt Improvement Prompt' continue to be highly regarded in online communities. The market also saw offerings like 1min.AI, which provides combined access to various AI models, including GPT, Gemini, and Claude, through a lifetime subscription deal available this week. Additionally, new hosted agent services are emerging, allowing users to deploy persistent agents without running their own servers, with plans starting at $29 per month.
Pattern watch
A clear pattern emerging this week is the increasing specialization and formalization of AI agent capabilities, particularly within developer workflows and critical sectors. The demand for an "agentic skill stack" in cybersecurity job postings highlights a structural shift, with specific skills like Python, prompt engineering, AI security, and agent orchestration becoming baseline requirements.
This trend is mirrored by the popularity of developer-focused tools such as the 'Superpowers' skill, which streamlines complex, multi-step development processes for AI agents. The ecosystem is moving beyond simple prompts towards agents that can execute sophisticated, multi-stage tasks autonomously, indicating a maturation of the installable AI expertise market.
Try this week
Consider exploring a community-contributed AI skill like 'Superpowers' for development tasks. Installation typically involves adding a repository for the skill via a command-line interface, after which the AI should automatically recognize it upon restart.
