Stop Copying Skills Between Claude Code, Cursor, and Codex

This is part five in a series about wrangling the growing pile of skills, scripts, and context that AI coding agents depend on. In part one, I covered why progressive disclosure beats dumping everything into context. Part two showed how akm unifies your local assets across platforms into one searchable stash. Part three added remote context via OpenViking for teams. And part four plugged in community knowledge through Context Hub. All of that assumed you were picking one tool. But you're probably not. You've got Claude Code at work, Codex for side projects, Cursor for quick edits. Each one has its own skills directory — ~/.claude/skills/, ~/.codex/skills/, .cursor/rules/ — and none of them can see each other. So you rebuild the same deploy skill twice. You forget where the good version of your testing scaffold lives. You copy files between directories and they drift within a week. You end up grepping across three different paths trying to find the one that handled database migrations c
