A good skill says when it should run, what inputs it needs, and what output counts as success.
Open agent skills by repeatable workflow
Browse skills by the behavior they package: browsing, coding, writing, commerce, research, memory, and general reusable agent procedures.
Skills are more valuable when they force the agent to inspect sources, collect proof, or run checks.
The best skill packs are easy to version, combine, and adapt to your team’s workflow.
Browser, QA, and web automation skills
