Assessment
Verdict
K12-teacher-skills is the most vertically focused first-party plugin in this wave: two SKILL.md files with extensive subject-area reference libraries (math, ELA, science, social studies curricula) plus Python renderers that produce print-ready HTML and DOCX lesson plans. The SKILL.md explicitly instructs Claude never to use deficit labels visible to students, and to reproduce no curriculum text verbatim — pedagogically sound guardrails that a generic LLM would never apply by default. Clean risk scan, well-maintained, and solves a real problem for teachers who don't want to explain context from scratch every session.

This listing is tied to a specific source commit and records both installation and risk checks.
Install check
✓ Pass
Two skills (k12-lesson-planning, k12-lesson-differentiation) with Python renderers for HTML and DOCX output. No network calls; renders locally.
Risk scan
✓ Clean
render_all.sh invokes Python renderers with local file paths only. No subprocess on user input, no eval/exec. SKILL.md includes both Apache-2.0 headers and a Learning Commons copyright — legitimate dual attribution.
