#
# agent-name is the persona name (e.g. "Dev-Agent", "QE-Agent"). It is used to
# prefix prompts so the model adopts the correct identity.
#
# Mode 1 (single-shot): claude -p, runs once and exits.
#   --dangerously-skip-permissions avoids blocking in non-interactive mode.
#   The project .claude/settings.json already sets permissionMode: bypass.
#
# Mode 2 (interactive polling): claude --agent, opens Claude Code TUI.
#   The agent file defines startup behavior (e.g. /loop 10m) and the
#   user can observe or interact at any time.
