discord — work with the user's Discord account

This skill has two modes, picked automatically by which credential the connector injected. Check the environment first and follow the matching section:

• $DISCORD_USER_TOKEN is set → User Token (BYOC) mode: full personal-account actions via the scripts/discord_user.py CLI (list channels, read messages, send / reply). This acts as the user's real account.
• only $DISCORD_TOKEN is set → OAuth mode: read-only identity + server list via curl. Channel messages are not available in this mode.

if [ -n "$DISCORD_USER_TOKEN" ]; then echo "mode: user-token (full)"; \
elif [ -n "$DISCORD_TOKEN" ]; then echo "mode: oauth (read-only)"; \
else echo "no Discord connection — connect at https://studio.acedata.cloud/console/connectors"; fi
