Anthropic Quietly Drops 2 Teacher-Focused SKILLs
Anthropic open-sources two production-grade K-12 teacher skills with full code, MCP integrations, and evaluation frameworks.
Anthropic quietly opened a repo called k12-teacher-skills, dumping the complete source code of the two official Agent Skills from Claude for Teachers.
At first I thought they were just two ordinary “AI helps teachers prepare lessons” skills. After digging through the code, I was genuinely impressed—Anthropic has personally stepped in and shown exactly what a production-grade skill should look like, from philosophy to engineering details, all laid out clearly for anyone to see.
Anyone building skills would be doing themselves a disservice if they didn’t take a look.
Introduction
Quick positioning statement:
Anthropic, in partnership with Learning Commons, built two Agent Skills for K-12 teachers. They’re packaged inside Claude for Teachers, and the full source code has been open-sourced.
The two skills have very clear roles:
k12-lesson-planning: Generates a complete lesson plan from scratch and delivers three Word documents in one go (teacher lesson plan + student materials + observation template).
k12-lesson-differentiation: Takes an existing lesson and adapts it into three tiers (Below / At / Above grade level), delivering four Word documents (teacher differentiation plan + three leveled worksheets).
