cron_explain — Translate a cron expression into plain English, list upcoming run times in a timezone, and report the gotchas that make schedules misfire: day-of-month/day-of-week OR semantics, steps that do not divide evenly, impossible dates, and daylight-saving shifts.
cron_build — Convert an English schedule description into a cron expression.
json_to_types — Convert a JSON sample into TypeScript interfaces and a matching Zod schema.
timezone_convert — Convert a wall-clock time between IANA zones.
color_analyse — Convert a colour between hex, RGB, HSL, OKLCH, CMYK, and CSS names, and derive complementary, analogous, triadic, split-complementary and monochromatic harmonies.
vocab_draw — Draw words-in-context practice questions from a curated bank.
vocab_check — Mark an attempt and get the teaching content: whether it was right, which option was correct, why it fits, and why EVERY distractor fails.
body_metrics — Compute BMI, energy expenditure, and protein targets from height and weight.
