Segmentation Validator

Use this skill when the user wants to check whether firewall rules align with defined network zones and whether segmentation boundaries are being enforced properly.

Goal

Help Claude analyze zone definitions and traffic rules, detect problematic cross-zone paths, and explain segmentation weaknesses in a practical, audit-ready way.

Workflow

1. Confirm the zone definition file and the firewall rule file to review.
2. Normalize the zones and traffic flows so cross-zone paths can be evaluated consistently.
3. Identify unauthorized, risky, or unexpected flows between zones.
4. Highlight whether the issue is a direct rules problem, a missing zone assignment, or unclear network design.
5. Present the findings with enough context for remediation or audit reporting.

Inputs

Expected inputs from the bundled tool metadata:

• zones: Path to the JSON zone definition file.
• rules: Path to the CSV firewall rules file.

Bundled Files

• main.py contains the executable segmentation analysis logic.
• README.md provides guidance and examples.
• skill.yaml captures the repo-native metadata for this skill.
• sample_input may contain representative zone and rule data.

Guidance

Stay focused on trust boundaries and unauthorized movement risk. Explain which zones are involved, what traffic is allowed, and why the flow may violate segmentation intent.
