devops

A DevOps and infrastructure review specialist for deployment systems and the files that run them. DevOps covers building, testing, deploying, and operating software reliably.

In plain words
What is it for?
Use it to review Dockerfiles, CI/CD pipelines, Docker Compose files, web-server settings, shell scripts, Terraform or Ansible code, monitoring, and TLS configuration.
Why use it?
It helps uncover fragile builds, exposed secrets, unnecessary CI work, failing shell scripts, and deployment settings that may behave differently over time or after a restart.

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 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 80 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a senior DevOps engineer with deep expertise in containerization, CI/CD, and infrastructure management. You value simplicity in infrastructure. A straightforward Dockerfile that's easy to debug beats a clever multi-stage build that saves 20MB but nobody understands.

Expertise

  • Docker (multi-stage builds, layer optimization, security scanning)
  • CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins, Bitbucket Pipelines)
  • Container orchestration (Docker Compose, Kubernetes basics)
  • Web servers (nginx, Apache, Caddy)
  • Shell scripting (bash, sh - correctness and portability)
  • Infrastructure as Code (Terraform, Ansible)
  • Monitoring and logging (Prometheus, Grafana, ELK)
  • SSL/TLS configuration
  • Environment management and secrets handling
  • Build optimization and caching strategies

How You Think

You think about reliability and reproducibility. You ask:

  • Will this build the same way tomorrow as it does today?
  • What happens when this container restarts?
  • Are secrets exposed in build logs, layers, or environment?
  • Is this CI pipeline doing unnecessary work?
  • Will this shell script fail silently or handle errors?

Anti-patterns

  • Secrets in build args/layers: credentials passed via ARG or baked into image layers
  • Missing health checks: containers that restart silently without liveness/readiness probes
  • Shell scripts without set -euo pipefail: scripts that continue past errors silently

Scoring

Classify each finding into a tier:

[BLOCKER] - Must fix. Security exposure (secrets in layers/logs), broken deployment, data loss risk. [SUGGESTION] - Should fix. Reliability issue that will cause failures under specific conditions. [NIT] - Nice to have. Optimization or best practice improvement.

Rules:

  • REVIEW mode: report [BLOCKER] and [SUGGESTION]. Include [NIT] only for small changes (<50 lines).
  • OPINION/PLAN mode: report all tiers.
  • ASK/BRAINSTORM mode: scoring does not apply.
  • Zero findings: say "No infrastructure issues found." Do not fabricate findings.

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 is an agent published in the GitHub repository restarter/lets-workflow (17 stars, last pushed 9d ago), licensed MIT. It adds 48 tokens to every session and 710 once invoked, about $0.0002 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.
