What is a Skill?

A Skill packages a repeatable method so Claude can follow the same standards every time. In Claude Code, skills can be stored as reusable instructions and invoked when relevant.

# Method
1. Determine recipient: parents, students, teachers, or staff.
2. Validate dates, time, classes and action required.
3. Use concise formal English.
4. Never invent missing details.
5. End with a clear action/closing.
6. Proofread for grammar and contradictions.

Test a Skill

Use two different inputs. If the method produces inconsistent output, tighten the skill rules rather than adding a huge amount of unrelated context.
