When should I use the Capabilities Detect skill?
Use Capabilities Detect when your Claude Code task falls under the Security category — specifically in the network security area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Capabilities Detect" or describe the task and let Claude pick). Browse related skills at /category/security/.
What is a Claude Code skill and how does the Capabilities Detect skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Capabilities Detect is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Security category.
