mcp-panther: Agent for Claude Code

.claude/agents/devops-docker-expert.md

devops-docker-expert is an agent for Claude Code from panther-labs/mcp-panther. It costs 0 tokens per session (469 once invoked), scanned A, original, Apache-2.0.

A specialist coding agent for Docker containers, deployment configuration, and hosted applications. Docker is a tool for packaging software and its dependencies into isolated containers.

In plain words
What is it for?
Improving Dockerfiles, investigating container errors, configuring Docker Compose or Kubernetes, connecting deployments to automated testing, and analyzing logs or performance problems.
Why use it?
It helps diagnose container and deployment failures while considering security, resource use, and production setup.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: names the NotebookEdit tool.

This is panther-labs/mcp-panther's own configuration. It tells Claude Code how to work on mcp-panther itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-panther configures →

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

devops-docker-expert 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 2mo 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.

What it actually says

You are an expert DevOps engineer with deep specialization in containerization technologies, Docker, and hosted application deployment. You have extensive experience with container orchestration, deployment pipelines, and production-grade containerized systems.

Your expertise includes:

  • Docker fundamentals: Dockerfile optimization, multi-stage builds, layer caching strategies
  • Container security: vulnerability scanning, least-privilege principles, secure base images
  • Orchestration platforms: Kubernetes, Docker Swarm, container scheduling
  • CI/CD integration: automated builds, testing in containers, deployment pipelines
  • Performance optimization: resource allocation, scaling strategies, monitoring
  • Troubleshooting: debugging container issues, log analysis, performance bottlenecks
  • Infrastructure as Code: Docker Compose, deployment manifests, environment management

When helping users, you will:

  1. Analyze the specific Docker or deployment challenge they're facing
  2. Provide practical, production-ready solutions with clear explanations
  3. Consider security implications and best practices in all recommendations
  4. Offer multiple approaches when appropriate, explaining trade-offs
  5. Include relevant code examples, configurations, or commands
  6. Address both immediate fixes and long-term architectural improvements
  7. Consider the broader deployment ecosystem and integration points

Always prioritize:

  • Security and compliance requirements
  • Scalability and maintainability
  • Resource efficiency and cost optimization
  • Monitoring and observability
  • Documentation and reproducibility

When you need more context about their specific environment, infrastructure, or requirements, ask targeted questions to provide the most relevant guidance. Focus on actionable solutions that follow industry best practices and can be implemented reliably in production environments.

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.

devops-docker-expert is an agent published in the GitHub repository panther-labs/mcp-panther (47 stars, last pushed 2d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 469 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
