Every month we look at what's climbing the MDSkill leaderboard — the skills getting the most installs from real developers. June 2026's list skews toward security and review skills, with a notable spike in documentation generators as teams adopt AI-first workflows.
Here's what's trending and why.
Why install count matters
Install count is a signal of genuine utility. A skill gets installed when a developer finds it in the directory, reads its description, checks the security score, and decides it solves a real problem. It's a higher bar than a star or a like.
Skills with high install counts also tend to have been tested across a wider range of codebases — edge cases that would break a niche skill have usually been surfaced and fixed.
How to install any skill on this list
Find the skill in the directory and copy the install command from its detail page, or run:
npx mdskill add owner/repo/skill-name
To explore what's currently available:
npx mdskill search "security review"

Trending categories this month
Security review skills
Security skills are the most-installed category in June. The pattern: teams that added AI agents to their workflow are now asking "how do we make sure the AI isn't shipping vulnerabilities?"
The answer is a security review skill that runs automatically on every PR. What's popular:
- OWASP Top 10 reviewers — broad coverage, good for teams new to security automation
- Dependency auditors — checks for CVEs in newly added packages
- Secret detectors — flags credentials committed accidentally

Code review skills
The second-fastest growing category. Teams that started with ad-hoc AI review are standardising with skills that enforce their own conventions — their severity ratings, their output format, their specific things to check.
Most popular variants: stack-specific skills (React, Python, Go) that catch language-specific footguns, not just generic patterns.
Documentation generators
The third big mover. As more developers use agents to write code, they're using agents to write the docs for that code too. Skills that generate JSDoc, API docs, and README content are seeing a sharp rise.
What's driving installs in June
Two trends stand out:
Team-level adoption. Individual developers who adopted agents last year are now rolling them out to their teams. Team rollouts require consistency — which means skills. Install counts are growing fastest for skills that encode team standards (code style, review format, doc conventions) rather than individual productivity tools.
Security pressure. AI-generated code is getting more scrutiny from security teams. Skills that add a security gate to the agent workflow are a popular answer to "how do we trust code that the AI wrote?"
Finding the current leaderboard
The MDSkill leaderboard updates in real time. The top skills by install count and security score are on the homepage and in each category page.
New skills are added daily as developers publish their workflows to public GitHub repos and submit them to the directory.
