Data modelling and DAX
Every chat you’ve ever had with GitHub Copilot is saved as a plain text file on your disk. Searchable, quotable, re-usable. Annual review prep, cross-chat handoffs, and ‘what was that thing I figured out three weeks ago’ all become trivial.
Auto-commit every 30 minutes via Task Scheduler. The cost of ‘try something risky’ drops to zero. Git isn’t just for code. It’s the safety net under a knowledge worker’s notes.
A good assistant doesn’t do everything themselves. They send the intern. Subagents are read-only sub-chats your main chat spawns to do the heavy reading and report back. Your conversation keeps its memory.
A good assistant doesn’t wait to be asked. They walk in with a briefing. A trigger phrase in custom instructions fires off a structured routine that reads my calendar, summarises emails, surfaces carry-forward items, and gives me a single morning report.
