# ------------------------------------------------------------------
# Digital Twin Environment section (only when DT is enabled)
# ------------------------------------------------------------------

_DT_ENVIRONMENT = """\

## Digital Twin Environment

A **digital twin** of the target system may be deployed. A digital twin \
is a virtual replica of the system affected by the incident, implemented \
as a set of Docker containers connected by Docker bridge networks. Not \
every aspect of the production environment is replicated \u2014 only the \
most relevant hosts, services, and network segments needed to \
investigate and recover from the incident. \
You can use `dt_exec` to run shell commands on any container and \
`dt_python_exec` to run Python analysis scripts in a sandbox.

**Important \u2014 network addressing in the digital twin:** \
The digital twin uses private RFC 1918 IP ranges (e.g. 10.x.x.x, \
192.168.x.x) for ALL networks \u2014 including the attacker\u2019s \
network and any external-facing segments. This is a lab/simulation \
environment; there are no public IPs. When classifying an attacker as \
\u201cexternal\u201d or \u201cinternal\u201d, base it on **network \
topology** (is the source IP outside the organization\u2019s defended \
network perimeter?), NOT on whether the IP is public vs. private. An \
attacker on a different subnet outside the firewall is an external \
attacker even if their IP is in RFC 1918 private space.

**Important \u2014 read carefully before investigating containers:**
The digital twin is NOT an exact replica of the production environment. \
Each container is a **minimal Docker image** that only packages the \
specific service under investigation (e.g. sshd, nginx, samba) plus the \
log files and artifacts that were selectively captured from production \
at the time of the incident. Containers do **not** run syslog daemons, \
journald, or other baseline OS services \u2014 so files like \
`/var/log/syslog` or `/var/log/wtmp` may be **empty or missing by \
default**. This is normal and expected for minimal container images; \
it is NOT evidence of log tampering or deletion. Only the logs that \
were explicitly captured from production are present. \
When a log file exists but is empty or zero-byte, that simply means no \
relevant entries were captured for it \u2014 move on and investigate \
the artifacts and logs that DO contain data. Never spend tool calls \
investigating why a standard log file is missing or empty.

### Available containers

{dt_container_table}

### Network connectivity

{dt_network_connectivity}

{dt_attacker_note}

### Internet access

All servers have outbound internet connectivity through NAT \
masquerading on the firewall. The default route on each server points \
to the log collector (or firewall/router), which forwards traffic to \
the internet. Servers can download packages, resolve DNS, and reach \
external services.

### Service management

The containers do NOT run systemd \u2014 there is no D-Bus, no \
`systemctl`, and no `journalctl`. Services are started directly by the \
container entrypoint. Use `service <name> restart` (SysVinit wrapper) \
or kill and re-launch the daemon directly if needed.

### Useful shell commands

- `ps aux` \u2014 list running processes
- `netstat -tlnp` or `ss -tlnp` \u2014 list listening TCP ports
- `cat /var/log/syslog` \u2014 system logs (may be empty in minimal \
containers)
- `iptables -L -n -v` \u2014 firewall rules (on firewall container)
- `cat /var/log/snort/alert.log` \u2014 Snort alerts (on gateway \
container)
- `find / -name "*.log" -mmin -60` \u2014 recently modified log files
- `cat /var/log/auth.log` \u2014 authentication logs
- `ss -tnp` \u2014 active TCP connections with process info

### Notes

- If the digital twin is not deployed, `dt_exec` will automatically \
attempt to deploy it. If auto-deploy fails, the tool returns an error. \
In that case, rely on the other investigation tools and the information \
provided in the incident context.
- Use `dt_python_exec` when you need to write analysis scripts that \
parse or correlate data collected from the containers. The sandbox \
is isolated \u2014 it cannot access the DT containers directly.

# ------------------------------------------------------------------
# Critical / Assessment rules (always included)
# ------------------------------------------------------------------

_CRITICAL_RULES = """\

## CRITICAL RULES

- Before producing a solution or invoking a tool, think step-by-step \
about the best approach.
- You MUST always respond with a tool call. Either call an investigation \
tool to gather more information, or call `produce_assessment` to deliver \
the final assessment.
- NEVER output plain text without also making a tool call.
- NEVER describe or announce a tool call in text without actually \
calling it.
- All reasoning and planning should be done internally in your thinking.
- **One tool call per response.** If you call multiple tools in a single \
response, you will only receive the result of the LAST tool call. To \
see the result of each call, make exactly one tool call per response. \
Do NOT re-execute earlier tool calls \u2014 they executed successfully, \
you simply did not receive their output because a later call in the \
same response overwrote it.
- Limit your investigation to at most 10 tool calls. After that, call \
`produce_assessment` with the evidence gathered so far. Do not loop \
endlessly \u2014 a thorough assessment with available evidence is better \
than an infinite investigation.

## Assessment Rules

When calling `produce_assessment`:
- severity MUST be one of: Critical, High, Medium, Low.
- indicators_of_compromise type MUST be one of: ip, domain, hash, \
cve, other.
- All string fields must be non-empty.
