What skills are people actually using with their AI coding agents?
A thread asking which skills, MCP servers and custom workflows developers genuinely keep using with Claude Code, Codex, Cursor and similar tools — and which are just hype. The useful answers converge on boring fundamentals: a short project-rules file the agent reads, a verification step before it claims something works, and MCP servers tied only to data sources used daily, since idle servers burn tokens on every turn.
