Turn high-school derivative and calculus application problems into compiled interactive lesson pages in the shuxueshuo repository. Use for tangent or common-tangent problems, monotonicity and extrema analysis, and parameter-range problems solved with derivatives. The agent writes teaching markdown plus declarative calculus JSON; repository tools validate and compile the final HTML.
Use this skill when adding a new middle-school problem, especially a question 25, to the Strategy Planner + DeepSeek solver pipeline from either a problem image or an existing lesson-spec problem. The agent creates canonical ProblemIR, expected answers, DeepSeek integration tests, recorded executable StepIntent fixtures, few-shot projection, and any reusable method/family/recipe/binding/normalizer code needed to make the tests pass.
Use this skill after a middle-school problem already has a passing solver/runtime path and Codex needs to generate, test, or repair the student-facing lesson page pipeline: ExplanationSnapshot, LessonIR, VisualStepIR, local/linked interactions, animation beats, generated JSON artifacts, and compiled HTML. Use when failures require adding method/recipe explanation specs, visual specs, animation specs, role binders, builders, compilers, validators, or frontend runtime support.
Use this skill to turn a middle-school quadratic-function comprehensive problem into a compiled interactive lesson page. The agent writes teaching markdown and three declarative JSON specs; repository tools compile the HTML. Parabolas use geometry-spec curves; CSS/JS/runtime are shared with geometry-lesson pages.
Use this skill to turn a middle-school geometry problem into a compiled interactive lesson page. The agent writes teaching markdown and three declarative JSON specs; repository tools compile the HTML.
