+# Eval Test Skill
+
+This skill provides greeting templates for various contexts.
+
+## Usage
+
+When asked to greet someone, use one of the following templates:
+
+- **Formal**: "Good day, {name}. How may I assist you?"
+- **Casual**: "Hey {name}! What's up?"
+- **Technical**: "Hello {name}, ready to debug some code?"
+
+## Notes
+
+This skill is a fixture for the picoclaw evaluation harness.
+The marker `eval-skill-loaded` confirms this skill was successfully read.
