Install with the CLI

In a terminal, from the folder you want:

npx --yes palatekit@latest install agent-host-capability-matrix

With no option, the skill goes to ~/.agents/skills/; add --agent claude-code (or codex, cursor…) to target an agent.

First time: connect the CLI with

npx --yes palatekit@latest login

The agent compares the APIs available in Microsoft 365 Copilot and other hosts, then adds detection guards so buttons do not silently stop working. You get a portable widget and a list of what to check at runtime.
