Skills
Skills extend what your agents know how to do well.
Instead of rewriting the same instructions from scratch every time, you install (or write) a skill once, and every agent that needs it gets better at that category of work.
The Skills Marketplace
AIDEN includes a built-in marketplace where you can:
- browse a curated registry of skills from the skills.sh ecosystem
- install a skill in one click
- manage installed skills — enable, disable, or remove them
- configure per project — a skill can be active in one project and off in another
What skills are good for
Skills shine on repeated categories of work, for example:
- frontend implementation — component conventions, styling discipline, accessibility habits
- backend reasoning — API design, data modeling, migration safety
- security review — a consistent checklist instead of an ad-hoc glance
- documentation — tone, structure, and completeness rules for user-facing writing
- domain workflows — anything specific to your product or stack that agents should always know
Creating your own skills
You can also write custom skills for the patterns unique to your team: your naming conventions, your review checklist, your deployment rules. Once written, they behave like any installed skill — reusable across stories and agents, configurable per project.
A good custom skill is like a good agent: narrow, opinionated, and written for a real repeated need.
Best practice
Add skills when they solve a repeated need, not as decoration. The best skills remove friction from real work — if you keep correcting an agent about the same thing, that correction probably wants to become a skill.
