Documented error codes include AUTHENTICATION, UNKNOWN_ARGUMENT, ARGUMENT_ERROR, and BAD_REQUEST. Installation is a single shell command piping a script into sh, downloading from GitHub releases, verifying checksums, and installing to `~/.local/bin/pplx` without sudo. Platform coverage is limited to macOS on Apple Silicon, Linux x86_64, and Linux arm64, with no Windows or Intel macOS build. Token budgeting features include `--output-dir` to save results to JSON files and `--stdout-preview[=<CHARS>]` to truncate long string fields, which is a no-op without a save directory.
