Global Flags

All commands output JSON to stdout, errors to stderr.

Interactive REPL

Run tail-fin without a subcommand (or pass the top-level --repl flag) to start an interactive session:

$ tail-fin --connect 127.0.0.1:9222
tail-fin> sa quote AAPL
{...}
tail-fin> twitter timeline --count 5
{...}
tail-fin> quit

Global flags (--connect, --cookies, --headed) are captured at launch and apply to every command in the session; they cannot be changed inside the REPL (restart to switch). Unknown commands and parse errors keep the session alive — only quit, exit, or Ctrl+D end it. Piped input (echo "sa quote AAPL" | tail-fin) runs commands silently, useful for scripted sequences.

Note: arguments are split on whitespace inside the REPL; commands with quoted args (e.g. twitter search "rust lang") should be run in one-shot mode.
