Agent Usage

This CLI is designed for AI agent consumption:

Non-interactive - never prompts, every input is a flag
Pipeable - --json output to stdout, errors to stderr
Filterable - --select id,name returns only fields you need
Previewable - --dry-run shows the request without sending
Read-only by default - this CLI does not create, update, delete, publish, send, or mutate remote resources
Offline-friendly - sync/search commands can use the local SQLite store when available
Agent-safe by default - no colors or formatting unless --human-friendly is set

Exit codes: 0 success, 2 usage error, 3 not found, 5 API error, 7 rate limited, 10 config error.
