Configure Istio routing, load balancing, circuit breakers, and canary deployments for service mesh traffic policies.
Works with
Covers four core resources: VirtualService for host-based routing, DestinationRule for service-level policies, Gateway for ingress/egress, and ServiceEntry for external services
Includes templates for basic routing, canary deployments (weighted traffic splits), circuit breakers with outlier detection, retries with timeouts, traffic mirroring, and fault injection

Before installing skills in Cursor, ensure your development environment meets these requirements:
node --versionistio-traffic-managementExecute the skills CLI command in your project's root directory to begin installation:
Fetches istio-traffic-management from wshobson/agents and configures it for Cursor.
The CLI shows a list of agents. Use arrow keys and space to select Cursor:
Confirm successful installation by checking the skill directory location:
Restart Cursor to activate istio-traffic-management. Access via /istio-traffic-management in your agent's command palette.
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your environment. Always review source, verify the publisher, and test in isolation before production.

Comprehensive guide to Istio traffic management for production service mesh deployments.
| Resource | Purpose | Scope |
|---|---|---|
| VirtualService | Route traffic to destinations | Host-based |
| DestinationRule | Define policies after routing | Service-based |
| Gateway | Configure ingress/egress | Cluster edge |
| ServiceEntry | Add external services | Mesh-wide |
Client → Gateway → VirtualService → DestinationRule → Service

Steps
Common Pitfalls
✓ Do
✗ Don't
💡 Pro Tips
✓ Use when
Use for user story writing, competitive research, roadmap prioritization, stakeholder communication, and PRD drafting. Best for reducing repetitive documentation and research work.
✗ Avoid when
Avoid for strategic product vision (requires deep customer empathy), pricing decisions (needs market and financial expertise), or when face-to-face customer discovery is more valuable than speed.
