Kubeshark Traffic

What it does

When your agent uses it

• Capturing Kubernetes pod traffic
• Debugging service-to-service latency
• Exporting pcaps from a cluster
• Analyzing encrypted east-west traffic

Example prompts

• “/kubeshark-traffic”

Workflow steps

8 steps, taken from the first numbered list in SKILL.md.

1. 1Capture traffic: capture_traffic(filter="src.pod.name == 'frontend'") — start targeted capture
2. 2List flows: list_l4_flows — see all TCP/UDP connections with RTT and stats
3. 3Flow summary: get_l4_flow_summary — identify top talkers and protocol breakdown
4. 4Apply filter: apply_filter(kfl_expression="response.status >= 500") — isolate errors
5. 5Export pcap: export_pcap(filter="dst.pod.name == 'api-gateway'") — export for deep analysis
6. 6Cross-reference: Use packet-analysis skill to analyze exported pcap with tshark
7. 7Report: Service communication analysis with latency, error rates, and traffic patterns
8. 8GAIT: Record all captures and findings in audit trail

What it can do on your machine

Read from SKILL.md and the folder at commit aa90e7d. It shows what the files ask for, not the result of running them.

• Tool permissions

  Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

  From allowed-tools in the SKILL.md frontmatter.

• Runs code

  Shell commands in SKILL.md call:

  • kubectl
  • helm

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • github.com
  • docs.kubeshark.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names no API keys, tokens, secrets or passwords.

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Kubeshark Traffic loads about 2k tokens when it runs. Until then it costs about 78 tokens; SKILL.md has 680 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~78

When it runs · the whole SKILL.md, loaded when a task matches

~2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
