AI coding agents have quietly gained a superpower most people haven't fully explored yet: **skills**.

I run a directory that evaluates AI agent skills. Every skill that wants a listing goes through a six-dimension rubric — trigger quality, structure, workflow design, content, engineering, and security. The security di…

The skill ecosystem is a gold rush right now, and most of what's being panned is fool's gold. A skill is just a folder with a `SKILL.md` that teaches your agent a job — but the gap between a great one and a lazy promp…

Video is where agent skills went from "nice trick" to "actual production tool" this year. The current wave doesn't generate video by hallucinating pixels — it writes code that draws every frame, synthesizes voiceover,…

Document work is the highest-demand category in the skill ecosystem, and it's where the gap between a great skill and a lazy prompt-wrapper is most expensive. A bad spreadsheet skill corrupts your formulas silently. A…

Developer tools is the most misunderstood skill category. The temptation is to grab "code generator" skills, but those just wrap what your agent already does. The skills that actually move the needle are the ones that…

Data analysis is a discipline with right answers, which makes it ideal territory for skills: the patterns are known, the failure modes are known, and an agent that has internalized both is dramatically better than one…

Design skills live or die on output quality, which makes them the hardest category to evaluate — and the easiest to fake. A prompt-wrapper can call itself an "infographic generator." Whether the infographics are actua…

Everyone's agent can already write. So what does a writing skill have to do to earn its place in your context directory? It has to make the writing **better in a specific, nameable way** — faster research integration,…

The marketing category has an unusual shape: instead of scattered individual skills, it's dominated by a family of purpose-built tools that cover the whole funnel — audience research at the top, SEO and ads in the mid…

The legal category is new, and it's growing fast. The skills in it are more cautious than most — they know their advice gets checked by people whose job is finding errors, and several are explicitly structured around …

The finance category is crypto-heavy, and that's not an accident: crypto is where the APIs are public, the data is free, and the workflows are code-native. Traditional finance hides behind terminals and data subscript…

The video category grew from nothing to one of the deepest collections in the directory in a matter of weeks, and it splits cleanly into two philosophies.
