Using a skill — day to day
Four steps from install to output
Install the skill
Pick a domain pod or single skill, install via your tool's marketplace or the convert script.
Describe the task
Tell your agent in plain language: "Run an accessibility audit on the homepage".
Skill auto-activates
The agent matches your request to the right skill's SKILL.md and follows its workflow.
Ship the output
Each skill includes templates, checklists, and CLI tools — you get a deliverable, not just advice.
