Troubleshoot Network Infrastructure
Network teams need reliable guidance for design, DNS, load balancing, and connectivity issues. This skill provides structured references and troubleshooting workflows for safe infrastructure decisions.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "network-engineering" from https://skillstore.io/skills/89jobrien-network-engineering.md and its manifest at https://skillstore.io/api/skills/89jobrien-network-engineering/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "network-engineering". A web service fails only through the load balancer.
Expected outcome:
- A layer-by-layer checklist covering listener rules, target health, security groups, routes, and application status.
- A short list of likely causes ranked by evidence needed.
Using "network-engineering". A domain migration needs minimal downtime.
Expected outcome:
- A DNS migration plan with TTL preparation, record validation, propagation checks, and rollback timing.
- A reminder to verify authoritative nameservers before the cutover.
Using "network-engineering". TLS errors appear after a certificate update.
Expected outcome:
- A certificate troubleshooting path covering chain order, hostname matching, protocol versions, and load balancer configuration.
- A concise incident summary template for the operations team.
Security Audit
SafeI found no malicious intent, prompt injection, secret access, or executable code in SKILL.md. The static hits are Markdown fences, documentation addresses, and standard network troubleshooting examples. Users should run diagnostic commands only against systems they own or are authorized to test.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Plan Cloud Network Layouts
Design public, private, and database subnet patterns for a multi-tier application.
Debug DNS and TLS Incidents
Work through DNS records, certificate checks, and load balancer symptoms during outages.
Review Connectivity Runbooks
Create step-by-step checks for ports, routes, interfaces, and service health.
Try These Prompts
Help me troubleshoot a connection failure between a client and an application server. Ask for missing details before recommending checks.
Design a VPC subnet plan for a three-tier web application across three availability zones. Include public, private, and database subnets.
Review my DNS migration plan for a production domain. Identify TTL changes, record validation steps, and rollback checks.
Create an incident workflow for intermittent TLS failures behind a load balancer. Separate certificate, cipher, routing, and health-check causes.
Best Practices
- Confirm authorization before running diagnostics against any host or network.
- Start with layer-by-layer checks before changing production configuration.
- Record expected state, observed state, and rollback steps for every change.
Avoid
- Running scan-like commands against systems without explicit permission.
- Changing DNS, routes, or firewall rules without a rollback plan.
- Treating example addresses or placeholder hostnames as production values.
