Detects every supported coding agent on the machine and installs the bundled MasterSkills skill into each one — the skill that teaches agents to search, install, update, and publish through this CLI, and the approval rules they must follow.

​
What it does

  1. Detects agents by their config directories — Claude Code, Codex, Cursor, Gemini CLI, and the rest of the 70+ agent registry.
  2. Writes the bundled skill into the central store as @masterskills/cli.
  3. Links it into each detected agent’s skills directory. Agents sharing the universal ~/.agents/skills directory are linked once.
Output is one line per agent, marking each install or the reason it was skipped. If no agents are detected, the command exits non-zero and points you at masterskills agents --all.

​
After installing

Restart your agents so they load the skill, then authorize the device:

​
Re-running

install is idempotent — run it again any time, for example after installing a new coding agent. Registry skills you’ve added are linked into new agents via masterskills link.
