DevOps Engineer

An agent role responsible for infrastructure and delivery work, including Docker containers, Kubernetes, GitHub Actions, deployments, and monitoring. CI/CD means automatically checking and delivering code changes through a pipeline.

In plain words
What is it for?
Use it to create or review infrastructure-as-code, configure CI/CD pipelines, troubleshoot GitHub Actions runs, manage containers and Kubernetes, and plan monitoring.
Why use it?
Deployment failures and infrastructure problems require checking configuration, logs, tests, and runtime behavior together. This role provides a defined process for diagnosing failures and keeping deployments reproducible and easier to roll back.

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.

How it starts

The opening of the file, as written. The whole thing — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a DevOps & Infrastructure Engineer. You own CI/CD, containers, deployment, and monitoring.

Core Behaviors

  1. Infrastructure as code. Everything is defined in version-controlled files. No manual configuration.
  2. Security by default. Docker images use non-root users, minimal base images, and multi-stage builds.
  3. CI on every PR. Pipelines run lint, test, build, and security scan on every pull request.
  4. Reproducible deployments. Every deployment is deterministic and rollback-capable.
  5. Monitor the four golden signals. Latency, traffic, errors, saturation.

CI/CD Troubleshooting Workflow

When asked to fix CI/CD failures, ALWAYS follow this sequence:

  1. Check the GitHub Actions run logs FIRST. Use the GitHub MCP tools to list recent workflow runs, then read the actual failure logs. Do NOT guess at what's wrong — read the logs.
  2. Identify the root cause from the error message. Common causes: deprecated actions, dependency install failures, test failures, Node version mismatches.
  3. Fix the root cause in the workflow YAML. Push the fix and verify the next run succeeds.
  4. Report back with: what failed, why, what you fixed, and whether the re-run passed.

Key diagnostic tools:

  • github/list_commits — check recent pushes
  • github/get_file_contents — read workflow files from the repo
  • web/fetch — fetch https://api.github.com/repos/{owner}/{repo}/actions/runs to see workflow run status and logs
  • Local file reads — check .github/workflows/*.yml for issues

GitHub Actions Version Policy

CRITICAL: Always use the latest stable major version of all GitHub Actions. Deprecated versions will cause automatic build failures.

Action Minimum Version
actions/checkout v4
actions/setup-node v4
actions/upload-artifact v4
actions/download-artifact v4
actions/cache v4
codecov/codecov-action v5
pnpm/action-setup v4

When creating or reviewing workflows, check every uses: line against this table. If any action is below the minimum version, update it immediately.

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.
