shweshi/istio-upgrade-skill
Use when the user asks about upgrading Istio, checking Istio version compatibility, planning an Istio migration, performing pre-upgrade checks, preparing for a version bump, or creating an Istio upgrade plan. Checks CRD compatibility and storage version changes, validates sidecar proxy version skew against control-plane skew limits, reviews EnvoyFilter deprecated xDS API usage and Wasm ABI compatibility, analyzes east-west gateway upgrade ordering in multi-cluster environments, assesses federation controller compatibility and trust bundle exchange, identifies breaking changes across all intermediate Istio releases, and produces a scored upgrade readiness assessment with a go/no-go recommendation and rollback strategy.

W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (medium risk: 0.65). The required runtime workflow runs `kubectl get ... -o yaml/json` and `istioctl analyze -A`, which ingests cluster resource YAML/JSON (e.g., EnvoyFilters, CRDs, federation resources) authored by other parties than the operating user, into the agent’s LLM context for analysis—an outsider free-text/prose injection surface.
