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

Both tokens are secret — full account access. Never echo or print them. On 401, the token expired or was revoked — tell the user to reconnect at studio.acedata.cloud/console/connectors. On 429, sleep the retry_after seconds, then retry; never parallelize.

User Token (BYOC) mode — full actions

When $DISCORD_USER_TOKEN is set, drive the user's real account through discord.py-self via the CLI at scripts/discord_user.py (run with python3). It logs in with the token only (no gateway) and prints JSON.

discord.py-self is preinstalled in the hosted sandbox (import name discord). Do not pip install it at runtime; if import fails, report that the sandbox image is missing the dependency and stop.

Writes (send / reply) are gated by a trailing --confirm. Without it they dry-run and print what they would send. Confirm the exact channel and content with the user before sending — it's irreversible and public. Only append --confirm (as the very last argument) once the user approves.

# identity (always run first)
python3 scripts/discord_user.py whoami
# list the servers (guilds) the account is in
python3 scripts/discord_user.py guilds
# list text channels in a server
python3 scripts/discord_user.py channels --guild GUILD_ID
# read recent messages in a channel
python3 scripts/discord_user.py messages --channel CHANNEL_ID --limit 20
# send — dry-run first, then re-run with a trailing --confirm
python3 scripts/discord_user.py send --channel CHANNEL_ID --text "hello"
python3 scripts/discord_user.py send --channel CHANNEL_ID --text "hello" --confirm
# reply to a specific message
python3 scripts/discord_user.py reply \
  --channel CHANNEL_ID --message MESSAGE_ID --text "on it" --confirm

--confirm is honored ONLY as the final argument (one strip), so a message body that merely contains the text --confirm can never silently trigger a send. IDs are numeric Discord snowflakes. A proxy can be forced via DISCORD_PROXY (falls back to HTTPS_PROXY / ALL_PROXY) if the sandbox needs one to reach discord.com.

OAuth mode — read-only

When only $DISCORD_TOKEN is set, drive the Discord API with curl + jq. Auth header is Authorization: Bearer $DISCORD_TOKEN; base URL https://discord.com/api/v10.

Scope is read-only identify + email + guilds. This mode can ONLY read the account's identity and its guild list. It CANNOT read/send channel messages, list a guild's channels or members, or manage anything — /guilds/{id}/channels, /channels/..., /guilds/{id}/members return 401/403 with an OAuth token. If the user needs those, they must connect Discord with a User Token (the BYOC mode above), or use a Discord Bot (discordbot connection) to act as a bot.

# identity (always run first)
curl -sS -H "Authorization: Bearer $DISCORD_TOKEN" \
  "https://discord.com/api/v10/users/@me" \
  | jq '{id, username, global_name, email, avatar}'

# the servers (guilds) the user is in (add ?with_counts=true for member counts)
curl -sS -H "Authorization: Bearer $DISCORD_TOKEN" \
  "https://discord.com/api/v10/users/@me/guilds?with_counts=true" \
  | jq 'map({id, name, owner, members: .approximate_member_count})'

Notes

A "server" in the UI is a "guild" in the API; messages live in channels inside guilds. In User Token mode: guilds → channels --guild <id> → act on a channel id. Don't invent ids.
In OAuth mode, owner: true means the user owns that guild. Guild icon URL (when icon is non-null): https://cdn.discordapp.com/icons/<guild_id>/<icon>.png (use .gif if the hash starts with a_). The guild list paginates at 200; paginate with ?after=<last_guild_id> if you ever hit it.
