Security Scan

This is an instruction-only skill that coherently and proportionately describes how to generate native eNSP .topo files and does not request unrelated credentials, installs, or elevated persistence.

Purpose & Capability

The name/description (eNSP topology generator) matches the content: SKILL.md and references describe building .topo XML, UUIDs, layout, device models, and writing a file. No unrelated environment variables, binaries, or config paths are requested.

Instruction Scope

Runtime instructions are narrowly scoped to parsing the user request, generating topology XML, and writing a .topo file. The SKILL.md references only local file creation (Write tool) and a local reference doc. It does not instruct reading unrelated files, calling external endpoints, or accessing secrets.

Install Mechanism

There is no install spec or code to download; the skill is instruction-only and will not write or execute external code during install.

Credentials

The skill declares no required environment variables, credentials, or config paths. The actions described (UUID generation, layout calculation, XML assembly, writing a .topo) require no secrets and are proportionate to the purpose.

Persistence & Privilege

always is false and the skill does not request persistent or elevated privileges or modify other skills' configuration. Autonomous invocation is allowed (platform default) and appropriate for a user-invocable generator.

Assessment

This skill appears to do exactly what it says: generate .topo files for eNSP. Before installing, confirm your agent environment provides a safe, limited Write tool (so generated files go only to the intended workspace). Review any generated .topo file before opening it in eNSP (just in case), and avoid granting the agent broad filesystem or credential access — this skill does not need them.

eNSP Topology Skill

Generate eNSP (Enterprise Network Simulation Platform) topology files as native .topo files that can be opened directly in eNSP.

How to create a topology

1. Parse user's request to identify:

   • Network devices (routers, switches, PCs, Cloud, etc.)
   • Connections between devices
   • Optional: text labels, area boxes

2. Generate UUIDs for each device using a valid UUID v4 format

3. Calculate layout coordinates for devices using auto-layout algorithm

4. Build the .topo XML following the format in references/topo-reference.md

5. Write the file to current directory using Write tool

6. Open the result - print the file path so user can open it in eNSP

Output format

Always output a .topo file. The user will open it in eNSP for simulation.

Example filenames:

• simple-network.topo
• ospf-topology.topo
• campus-network.topo

Layout algorithm

Use a simple grid-based auto-layout:

Grid spacing: 200px horizontal, 150px vertical
Device size: ~80x60px
Start position: (100, 100)

For each row:
  - Place devices horizontally with 200px gap
  - Move to next row when reaching canvas width (~1200px)

Adjust positions based on device types and connections to create logical groupings.

Adding text labels (txttips)

Common labels for network diagrams:

• Loopback addresses: Loopback0:10.0.1.1/24
• Network segments: 10.0.12.0/24
• Area labels: Area0, Area1, AS 64512
• Device roles: Core Layer, Access Layer

Adding area boxes (shapes)

Use type="1" shapes with appropriate colors to group devices:

• Same area devices in one rectangle
• Different colors for different areas/zones

File naming

• Use lowercase with hyphens
• Descriptive name based on topology purpose
• End with .topo extension

Opening the result

After writing the file, print the absolute path:

Topology saved to: C:\path\to\topology.topo
Please open this file in eNSP to view and simulate.

XML format reference

Consult references/topo-reference.md for complete XML structure including:

• Device XML format with slots and interfaces
• Line XML format with interfacePair details
• Shape XML format for area boxes
• Txttip XML format for text annotations
