From the source SKILL.md

A consumer building their product on top of this suite ships an LLM feature — a support chatbot, a doc assistant, an agent step. This skill helps them evaluate that shipped behaviour as a black box: the user describes what the feature is supposed to do; the skill runs adversarial probes and reports where it breaks.

What this skill does

Evaluate LLM Feature is a community-contributed Claude Code skill in the general-misc sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/evaluate-llm-feature/ and loads when your prompt matches the skill's trigger.

Who uses this skill
