k8s
Operate the joelclaw Kubernetes cluster — Talos Linux on Colima (Mac Mini). Deploy services, check health, debug pods, recover from restarts, add ports, manage Helm releases, inspect logs, fix networking. Triggers on: 'kubectl', 'pods', 'deploy to k8s', 'cluster health', 'restart pod', 'helm install', 'talosctl', 'colima', 'nodeport', 'flannel', 'port mapping', 'k8s down', 'cluster not working', 'add a port', 'PVC', 'storage', any k8s/Talos/Colima infrastructure task. Also triggers on service-specific deploy: 'deploy redis', 'redeploy inngest', 'livekit helm', 'pds not responding'.

3 findings — 3 medium severity. This skill can be installed but you should review these findings before use.
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 (high risk: 0.90). The skill's "Agent Runner (Cold k8s Jobs)" workflow in SKILL.md explicitly materializes a repository from REPO_URL/REPO_BRANCH (unrestricted) and executes code from it as part of the job-runner, meaning arbitrary third-party repository content can be fetched and interpreted at runtime and thus could inject instructions that influence tool use/actions.
W012: Unverifiable external dependency detected (runtime URL that controls agent)
What this means
The skill fetches instructions or code from an external URL at runtime, and the fetched content directly controls the agent’s prompts or executes code. This dynamic dependency allows the external source to modify the agent’s behavior without any changes to the skill itself.
Why it was flagged
Potentially malicious external URL detected (high risk: 0.90). The skill includes explicit runtime commands that fetch and execute remote Kubernetes manifests (e.g., "kubectl apply -f https://raw.githubusercontent.com/rancher/local-path-provisioner/v0.0.30/deploy/local-path-storage.yaml" and "kubectl apply -f https://github.com/kubernetes-sigs/metrics-server/releases/latest/download/components.yaml"), so these URLs are used at runtime to pull remote content that is directly executed as cluster configuration and are required steps in the documented recovery/install procedures.
W013: Attempt to modify system services in skill instructions
What this means
The skill prompts the agent to compromise the security or integrity of the user’s machine by modifying system-level services or configurations, such as obtaining elevated privileges, altering startup scripts, or changing system-wide settings.
Why it was flagged
Attempt to modify system services in skill instructions detected (high risk: 1.00). The skill instructs the agent to perform host-level state changes (editing Colima/docker host configs, launchd plists, port mappings, forcing container restarts, and running commands like sudo modprobe via colima ssh) that require elevated privileges and can modify system state, so it pushes the agent to compromise the machine.
