What problem does it solve? When working with the sd-* command pack, it is easy to lose track of which skills and commands are actually installed on a machine, which plugins are registered, or whether a referenced surface still exists. Guessing at command names or flags wastes turns and teaches names that will fail. ## Core Features & Use Cases - Live Catalog: Enumerates every installed sd-* skill and command by reading the rendered surfaces under platform homes (~/.claude, ~/.codex/skills, ~/.config/opencode/commands) at run time, never from a hardcoded list. - Plugin Registry Report: Lists plugins registered through sd plugin add with their declared prefix and interface version, plus the pack banner (checkout, commit, branch, dirty state). - Use Case: You are about to guess a command name or a flag, or something referenced a surface you cannot find. Run the catalog to see whether it is installed, missing, or renamed before acting. ## Quick Start Ask the assistant to list which sd-* commands and skills are currently installed on this machine and which plugins are registered.
