Before running the CLI, verify:
lensbinary is on PATH. Ifcommand -v lensreturns non-zero, tell the user: "lens CLI not found. Install withnpm i -g lens-engine."lens.ymlexists (useBashtool to test-f lens.yml). If not, tell the user: "Nolens.ymlfound. Run/lens:initfirst."
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.
