cz-agents-mcp: Skill for Claude Code

.claude/skills/smoke-test/SKILL.md

smoke-test is a skill for Claude Code from martinhavel/cz-agents-mcp. It costs 43 tokens per session (529 once invoked), scanned C, original, MIT.

A production health check for ten cz-agents containers, which are packaged services running on a server. It checks each service’s health endpoint and prints its name, port, version, and status.

In plain words
What is it for?
Run it after a deployment or when checking the state of the Hetzner production server; it also checks the web app.
Why use it?
It quickly shows which deployed services are working and which need investigation.

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 C, and why

smoke-test scanned grade C with 2 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 11d 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.

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

What it actually says

smoke-test

Check health of all cz-agents MCP containers on Hetzner production.

Run this Bash command via SSH

ssh -i ~/.ssh/id_rsa_macbook [email protected] "
printf '%-25s %-6s %-10s %s\n' 'SERVICE' 'PORT' 'VERSION' 'STATUS'
printf '%-25s %-6s %-10s %s\n' '-------' '----' '-------' '------'

  name=\$(echo \$entry | cut -d: -f1)
  port=\$(echo \$entry | cut -d: -f2)
  internal=\$(echo \$entry | cut -d: -f3)
  resp=\$(docker exec \$name wget -qO- http://localhost:\$internal/health 2>/dev/null || echo '{\"status\":\"DOWN\"}')
  ver=\$(echo \$resp | grep -oP '\"version\":\"\\K[^\"]+' || echo '-')
  st=\$(echo \$resp | grep -oP '\"status\":\"\\K[^\"]+' || echo 'DOWN')
  printf '%-25s %-6s %-10s %s\n' \$name \$port \$ver \$st
done
"

Expected output

All services should show ok. Any DOWN needs investigation.

Also check webapp

Changes

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.
