This module provides elicitation capabilities for background tasks running in Docket workers. Unlike regular MCP requests, background tasks don't have an active request context, so elicitation requires special handling: 1. Set task status to "input_required" via Redis 2. Send notifications/tasks/status with elicitation metadata 3. Wait for client to send input via tasks/sendInput 4. Resume task execution with the provided input This uses the public MCP SDK APIs where possible, with minimal use of internal APIs for background task coordination. ) annotationsN)datetimetimezone) TYPE_CHECKINGAnycast) ServerSession)get_task_contextget_task_session_idtask_redis_prefix)push_notification)FastMCPi task_scope str | Nonetask_idstrreturntuple[str, str, str]cHt|d|d}|d|d|dfS)zFBuild (request, response, status) Redis keys for a task's elicitation.:z:elicitz:requestz :responsez:statusr )rrprefixs h/home/rurouni/.hermes/hermes-agent/venv/lib/python3.11/site-packages/fastmcp/server/tasks/elicitation.py _elicit_keysr)sH!*-- @ @ @ @ @F   6 4 4 46H6H6H HHsessionServerSession | Nonemessageschemadict[str, Any]fastmcprmcp.types.ElicitResultc  K|j}|tdttj}t }|'|j}t|ddp t} ntdt||\} } } |||d} | 4d{V}| | | tj| td{V| | | dtd{Vdddd{Vn#1d{VswxYwYt!jt$j}d|d |||td zd d |d |||||d did}| >       U  ZZ --.,F &,#m:m44llJJ{++JJz** y--#<<(;;$LL33./                                          6     N             <<>>       U,, ;'' <(( :&&                                       W            9 ! !4 ! @ @@s5A?E EE'G??

Called by the notification subscriber when it detects an input_required notification with elicitation metadata. Sends a standard elicitation/create request to the client session, then uses handle_task_input() to push the response to Redis so the blocked worker can resume.
