| description | Use this skill to auto-generate a Blue Team member's realistic one-day activity timeline (network, application, human, and system actions) using the Cluster User Emulation System (CUE) by LiuYuancheng (https://github.com/LiuYuancheng/Cluster_User_Emulation_System). Trigger this skill whenever a user/operator asks to: simulate a blue team analyst's daily activity, build a defender persona for a cyber range/exercise, generate benign SOC/IT-admin traffic for DFIR training, create a scheduleProfile_<name>.py + scheduleCfg.txt deployment package, or populate a cyber range node with "normal user" background noise.

CUE Blue Team One-Day Activity Emulation Skill
1. What this skill does
This skill lets an agent act as the "Behavior Module Assembly" step of the
Cluster User Emulation System (CUE) workflow: given a blue-team role
(SOC analyst, network admin, incident responder, OT/ICS defender, IT support,
etc.), the agent selects Action API modules from CUE's Organic Actions
repository, arranges them into a timed playbook, and emits the deployable
profile files CUE expects (scheduleProfile_<Name>.py, scheduleCfg.txt,
and an actorFunctions_<Name>.py wrapper) so a User Action Emulator
instance can run that person's realistic one-day activity on a target node.
CUE itself does not take a natural-language prompt โ it takes Python
profile/config files. This skill is the missing "compiler" layer: it maps a
role + narrative day into the exact code CUE needs.
2. When to use this skill
Use it when asked to:
- "Generate a day in the life of a SOC analyst / network admin / IR responder for our cyber range."
- "Create blue team background traffic/activity for a DFIR exercise."
- "Build a CUE profile for user Alice who is a network administrator."
- "Add realistic defender noise to node X for 8 hours."
Do not use it to generate red-team/malware profiles (CUE's Malicious
repository) unless the user explicitly asks for adversary emulation and the
context is an authorized exercise โ flag that distinction back to the user
if ambiguous.
3. Required inputs (ask if missing)
| Input | Purpose | Default if unspecified |
|---|
| Persona name | Used as <Name> in file names / Own_ID | Analyst01 |
| Role | Picks the activity mix (see ยง5) | SOC_Analyst |
| Shift window | Start/end time for the day | 08:00โ17:00 |
| Target OS | Windows vs Linux affects which Action modules apply | Windows |
| Node network identity | OWN_IP, HOST_PORT | 127.0.0.1:3001 |
| Orchestrator hub | HUB_IP, HUB_PORT, whether to auto-register (RPT_MD) | 127.0.0.1:5000, True |
| Realism level | Regular fixed-time tasks vs randomized jitter | randomized ยฑ10 min |
If the user hasn't specified these, proceed with the defaults and state the
assumption โ don't block on asking unless the target environment (real vs
lab) is unclear, since that changes IP/credential handling.

Always include a small amount of "human realism" filler (13, 28, 30/33b, 31)
spread through the day โ a persona that only does security tooling all day
reads as artificial.
6. Workflow the agent should follow
- Clarify persona using ยง3 table; confirm role preset from ยง5 or accept
a custom action list from the user.
- Build the timeline โ draft a table:
time | Action # | module | purpose
covering the full shift, with 8โ20 events for a normal day (fewer for a
short demo, more for a dense exercise). Space actions realistically
(mornings: triage/inbox/dashboards; midday: investigation/meetings;
afternoon: reporting/handover). Add ยฑ jitter if "randomized" realism was
requested.
- Generate the profile package, producing these files (see the
Deployment Introduction doc for the full template):
scheduleCfg.txt โ connection/runtime config (Own_ID, OWN_IP,
HOST_PORT, RPT_MD, HUB_IP, HUB_PORT, PROFILE)scheduleProfile_<Name>.py โ the timeline/playbook definitionactorFunctions_<Name>.py โ thin wrapper functions that import and
call the specific Action API classes/functions from ยง4 for each
scheduled event
- Sanity-check the package: every action in the timeline must map to a
module that exists in the Action API doc; every credential/target field
must be a placeholder (
<FILL_IN>) unless the user supplied real lab
values โ never invent real IPs/credentials/URLs.
- Hand off the package with the Deployment Introduction steps so the
user can install it on the target node and register it with the
Orchestrator / Scheduler Monitor Hub.
- Do not wire up real destructive or intrusive actions (Modbus/RTU
writes, Ettercap mirroring, nmap sweeps) against anything other than a
user-confirmed lab/range target โ these can affect real OT/network
equipment.
7. Safety boundaries
- This skill is for benign/organic activity generation only. If asked to
wire in the Malicious repository (credential theft, DoS, ransomware-style
modules), stop and clarify scope; that is a distinct red-team capability
of the same project and requires explicit, clearly-authorized-exercise
framing.
- Never populate real target IPs, hostnames, credentials, PLC/RTU addresses,
or email accounts unless the user explicitly provides them for their own
authorized environment.
- Nmap scans, Modbus/Siemens writes, and Ettercap mirroring can affect live
industrial or network equipment โ confirm the target is a lab/cyber-range
asset before including them in a generated profile.
