Propagate Hissab's syntax documentation from its source of truth (lib/documentation/) out to every downstream surface — the five README.md files and the in-app docs under app/src/docs/. Invoke whenever lib/documentation/ changes (a new category, function, operator, unit, or syntax rule), when engine features land that users need to know about, or when the user asks to "sync docs", "update the docs", "update the READMEs", or fix doc drift. Verifies every example against the real engine before finishing.

Use the Hissab calculator CLI to evaluate deterministic math, unit conversions, date/time arithmetic, percentages, statistics, bitwise ops, number-system conversion, and color math from natural-language prompts. Invoke when the user asks for any calculation that should be hallucination-free, when they reference Hissab, or when results need exact precision the model should not compute itself. The skill translates natural-language intent into Hissab expressions, shells out to the local `hissab` binary via Bash, and parses stdout.
