Improve, rewrite, and explain workplace English for an English-as-a-second-language professional in Australia. Use when the user asks to polish, fix, rewrite, improve, or check work emails, Slack or Teams messages, follow-ups, replies to managers or stakeholders, technical explanations, status updates, polite chasing messages, questions, pushback, issue explanations, or similar workplace communication for Australian companies. Ask targeted clarifying questions before rewriting when the intended meaning, recipient, action, deadline, blame, commitment, or technical conclusion is unclear.

Structure any communication artifact — documents, reports, plans, issue comments, PR descriptions, emails, presentations, slides, charts, and dashboards — using Jean-luc Doumont's "Trees, Maps, and Theorems" method. Use whenever the goal is to get a message across to a busy audience, when asked to improve clarity or structure of writing or slides, or when a deliverable will be judged by whether readers act on it, not just read it.

This skill covers detecting anomalies in Modbus/TCP and Modbus RTU communications in industrial control systems. It addresses function code monitoring, register range validation, timing analysis, unauthorized client detection, and deep packet inspection for malformed Modbus frames. The skill leverages Zeek with Modbus protocol analyzers, Suricata IDS with OT rules, and custom Python-based detection using Markov chain models for normal Modbus transaction sequences.
