aenv

Use when the user wants to set up, switch between, or manage `aenv` namespaces — named bundles of CLAUDE.md, skills, MCP entries, and other AI-coding-harness config — in a project OR globally across `$HOME`. Triggers include `aenv …` mentioned directly, "switch namespace/profile", "activate/deactivate", "create/snapshot a namespace", "install a skill (from GitHub)", "auto-activate on cd", "what namespace am I using"; and for the global scope: "swap my global/user-level config (`~/.claude`, `~/.codex`)", "use a different Claude Code setup globally", "onboard a config repo like claude-ctrl", "swap back to my old setup". Don't use for secrets, Python venv, or Claude Code plugin marketplace ops.
