+Copilot CLI installs the same plugin via its `/plugin` commands and loads the skills and subagents directly. Subagent `tools` are declared as YAML arrays of Claude tool names (`[Read, Grep, Glob, Bash, …]`); Copilot resolves these case-insensitively to its own primitives (`read`, `search`, `execute`, `web`), so the agents get full file/search/shell/web access rather than the bare baseline.
