description	Append a new lens to lens.yml and generate its initial content.
allowed-tools	Bash(lens:*)
argument-hint	<name> --description "<text>" [--path <path>]

Before running the CLI, verify:

1. lens binary is on PATH. If command -v lens returns non-zero, tell the user: "lens CLI not found. Install with npm i -g lens-engine."
2. lens.yml exists (use Bash tool to test -f lens.yml). If not, tell the user: "No lens.yml found. Run /lens:init first."

The CLI requires <name> and --description "<text>"; it will exit non-zero with a clear error if either is missing. Run (passing arguments through verbatim):

lens add $ARGUMENTS

Stream the CLI's stdout/stderr to the user. If it exits non-zero, surface the error clearly.
