Design, build, review, or improve production-grade CLI and terminal TUI output and interaction surfaces. Use for command output, help/usage, errors and recovery copy, status/progress, logs, tables/trees/diffs, prompts and selection menus, destructive confirmations, agent-chat TUI transcripts and intermediate states, machine/JSON/NDJSON output for scripts or agents, stdout/stderr and exit-code contracts, CJK/wide-character layout, NO_COLOR, non-TTY, TERM=dumb, pipe, and CI behavior. Covers how terminal surfaces look, read, degrade, communicate state, and expose interaction contracts; not command/flag API design or low-level terminal input implementation.

Use when a user wants to generate, extract, audit, or refine a Google DESIGN.md file from one or more ordinary public website URLs rather than from a Stitch project.
