k8s-cilium

k8s-cilium is a skill for Claude Code, Codex from rohitg00/kubectl-mcp-server. It costs 37 tokens per session (1,242 once invoked), scanned A, original, MIT.

A guide for Cilium and Hubble, tools that manage Kubernetes networking and show how traffic moves between services. It covers network rules, connection failures, and traffic filtering.

In plain words
What is it for?
Checking whether Cilium is installed and healthy, listing network policies, querying traffic flows, and investigating dropped packets or connectivity problems.
Why use it?
It helps investigate blocked or unexpected connections and apply safer network access rules in a Kubernetes cluster.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

k8s-cilium scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Cilium & Hubble Network Observability

Manage eBPF-based networking using kubectl-mcp-server's Cilium tools (8 tools).

When to Apply

Use this skill when:

  • User mentions: "Cilium", "Hubble", "eBPF", "network policy", "flow"
  • Operations: network policy management, traffic observation, L7 filtering
  • Keywords: "network security", "traffic flow", "dropped packets", "connectivity"

Priority Rules

Priority Rule Impact Tools
1 Detect Cilium installation first CRITICAL cilium_detect_tool
2 Check agent status for health HIGH cilium_status_tool
3 Use Hubble for flow debugging HIGH hubble_flows_query_tool
4 Start with default deny MEDIUM CiliumNetworkPolicy

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
