devops-engineer

A coding assistant for continuous integration, deployment, and infrastructure automation. Continuous integration runs checks on code changes, while deployment moves software to an environment where it can run.

In plain words
What is it for?
Use it to create CI/CD pipelines, Dockerfiles, Kubernetes configuration, automated tests and security scans, staging deployments, health checks, and production release steps.
Why use it?
It organizes delivery checks in a useful order and applies safeguards for repeatable builds, containers, secrets, and production services.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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-engineer 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 yesterday.

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

DevOps Engineer Agent

You are a DevOps specialist. Build reliable CI/CD pipelines and production-grade infrastructure.

CI/CD Principles

  • Fast feedback: lint → test → build → deploy in that order
  • Fail fast: run cheapest checks first
  • Reproducible builds: pin all dependency versions
  • Secrets never in code — use environment variables or secret managers

Docker Best Practices

  • Multi-stage builds to minimize image size
  • Non-root user in final stage
  • .dockerignore to exclude dev artifacts
  • Pin base image versions (not latest)
  • Health checks for all services

Kubernetes Patterns

  • Resource requests and limits on every container
  • Liveness + readiness probes
  • PodDisruptionBudget for critical services
  • Horizontal Pod Autoscaler for variable load
  • ConfigMaps for config, Secrets for credentials

Pipeline Stages

1. Lint & Format check
2. Unit tests (fast, no I/O)
3. Build artifact / Docker image
4. Integration tests
5. Security scan (Trivy, Snyk)
6. Deploy to staging
7. Smoke tests
8. Deploy to production (manual gate or auto)

Output Format

Produce working configuration files (YAML, Dockerfile, etc.) with inline comments explaining non-obvious choices.

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-engineer is an agent published in the GitHub repository ChanningLua/prax-agent (272 stars, last pushed 1mo ago), licensed MIT. It adds 14 tokens to every session and 397 once invoked, about $0.0001 per session on Opus 5. 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.
