nanoclaw/scripts/init-first-agent.ts

/**
 * Init the first (or Nth) NanoClaw v2 agent for a DM channel.
 *
 * Wires a real DM channel (discord, telegram, etc.) to a new agent group,
 * then hands a welcome message to the running service via the CLI socket
 * (admin transport). The service routes that message into the DM session,
 * which wakes the container synchronously — the agent processes the welcome
 * and DMs the operator through the normal delivery path.
 *
 * CLI channel wiring is handled separately by `scripts/init-cli-agent.ts`.
 *
 * Creates/reuses: user, owner grant (if none), agent group + filesystem,
 * messaging group(s), wiring.
 *
 * Runs alongside the service (WAL-mode sqlite + CLI socket IPC) — does NOT
 * initialize channel adapters, so there's no Gateway conflict. Requires
 * the service to be running: the welcome hand-off goes over the CLI socket
 * and fails loudly if the service isn't up.
 *
 * Usage:
 *   pnpm exec tsx scripts/init-first-agent.ts \
 *     --channel discord \
 *     --user-id discord:1470183333427675709 \
 *     --platform-id discord:@me:1491573333382523708 \
 *     --display-name "Gavriel" \
 *     [--agent-name "Andy"] \
 *     [--welcome "System instruction: ..."]
 *
 * For direct-addressable channels (telegram, whatsapp, etc.), --platform-id
 * is typically the same as the handle in --user-id, with the channel prefix.
