Calculus Analysis with Symbolic Notation and Interval Formatting
100 / 100 · Low risk
Fine to try.
Analyze functions to find critical points, local extrema, concavity intervals, and inflection points using the Second Derivative Test. Output must strictly follow specific symbolic notation rules, including using 'co' for infinity, 'U' for unions, 'Ø' for empty intervals, and 'DNE' for non-existent values.

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'calculus-analysis-with-symbolic-notation-and-interval-formatting' ~/.claude/skills/'calculus-analysis-with-symbolic-notation-and-interval-formatting' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
