A guide to the category
Agent Skills & Plugins
Browse an editorial selection of agent skills and plugins on GitHub. Compare supported agents, installation scope and the permissions each workflow needs.
Look for a skill that improves a specific task you already do: planning, reviewing a change, working with documents or producing a design. Read the instructions before installing them. A small instruction pack and a plugin that runs code need different levels of inspection.

What to check before choosing
Which agent and format does it target?
Check the supported client, installation path and version requirements. Identify whether the package contains plain instructions, executable scripts, external services or a combination.
What can installation and execution change?
Inspect setup commands, dependencies and requested account access. Use the narrowest installation scope that fits the task and check how to remove or disable the package.
Does it improve a real task?
Compare a small task with and without the skill using your own acceptance criteria. Review both the result and any extra steps or tool calls the instructions introduce.
