Original guides and editor's notes for agent skills, DeepSeek Harness plugins, and large language models. We tell you when to skip something, not just what to install.
Behind these pages sits a searchable directory of agent skills, DeepSeek Harness plugins, and large language models. Cards describe the publisher's work; our own writing is marked.
An editorial layer over a large directory
AI Agent Hub indexes agent skills, DeepSeek Harness plugins, and large language models. The cards help you find a name, a publisher, and the upstream source. The guides, editor's notes, comparisons, and glossary are written for this site: when a tool fits, when it does not, and how the ordering on this site actually works.
If you are here to decide, start with a guide rather than a search box. Search, sort, and page numbers remain available, but they stay out of the crawl so the pages with a full explanation are the ones search engines spend time on.

Beyond the directory
Three more shelves hold work made here rather than summarized: articles argue one position about tools and working habits; browser tools count, format, convert, and check without sending your input anywhere; small games are short breaks with complete rules and no account.
Every one of those pages is dated in the changelog. If you cannot decide where to start, let the site pick.
A practical way to pick one agent skill from this directory without installing a pile of prompts you will never run again.
What the install prompt on a skill page actually does, how to tell that it took effect, and how to take it back out.
The cases where a skill card should stay a card: secrets, personal data, licenses you cannot accept, and prompts that fight your agent.
What a DeepSeek Harness plugin is, how it differs from an agent skill, and how to try one without losing the session you were in.
What each DeepSeek Harness plugin category is promising, and the mix-ups that waste an afternoon.
What the fields on a model page mean, which ones are safe to compare, and which ones are just the vendor's sentence.
Editor's picks
Items we have written a full note for, and why they are on the listAn editor's comparison of two flagships at different price points: where the gap is real, where it is a rounding error, and which one belongs in a high-volume pipeline.
Two listings that both look suited to long inputs, compared on the four fields that actually decide a long-document workload: context, price, license, and hosting.

ModLens is a vision plugin for DeepSeek Harness that gives text-only models sight by reading images pasted directly into chat, with zero-config setup and multiple vision engines.
An agent skill where the model writes a Markdown draft and the bundled CLI renders a readable, offline single-file HTML page with diagrams and tables using about one-eighth the output tokens of hand-written HTML.
