 ## IRC command hooks

     - This hook is sent whenever an oper-up is successful: when a user with umode `+o` is bursted, when umode `+o` is set, etc.
     - The `text` field denotes the oper type (not the SWHOIS), which is used for WHOIS replies on different IRCds.

+- **PYLINK_CUSTOM_WHOIS**: `{'target': UID1, 'server': SID1}`
+    - This hook is called by `coreplugin` during its WHOIS handling process, to allow plugins to provide custom WHOIS information. The `target` field represents the target UID, while the `server` field represents the SID that should be replying to the WHOIS request. The source of the payload is the user using `/whois`.
+    - Plugins wishing to implement this should use the standard WHOIS numerics, using `irc.proto.numeric()` to reply to the source from the given server.

 ## Commands handled WITHOUT hooks
 At this time, commands that are handled by protocol modules without returning any hook data include PING, PONG, and various commands sent during the initial server linking phase.
