What is infra-engineer?

A guide for infrastructure work: running software in the cloud, packaging it with Docker, managing Kubernetes, setting up automated delivery, controlling cloud costs, and handling security checks.

Use it for AWS, Azure, Google Cloud, Cloudflare, Docker, Kubernetes, CI/CD pipelines, infrastructure configuration, cloud-cost reviews, and DevSecOps work.

It brings related infrastructure tasks and platform details into one place, so developers do not need to piece together separate deployment instructions.

Install

Getting it into your agent

It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Clone the repo

git clone --depth 1 https://github.com/ushibo/brigade

agentmods

npx agentmods add skills/ushibo/brigade/infra-engineer

Made for: Claude Code.

Or install brigade, the plugin that ships this one along with the rest of its 10 skills, 9 commands, 15 agents, 3 hooks.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00294	$0.05816
Opus 5.5	$0.00118	$0.02326
Sonnet 5.5	$0.00059	$0.01163
Haiku 4.5	$0.00029	$0.00582

Security

Grade D, and why

infra-engineer scanned grade D with 3 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 1mo ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/cloudflare_deploy.py, scripts/docker_optimize.py, scripts/tests/test_cloudflare_deploy.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

Infrastructure Engineering Skill

Comprehensive guide for modern infrastructure engineering covering DevOps practices, multi-cloud platforms (AWS, Azure, GCP, Cloudflare), FinOps cost optimization, and DevSecOps security practices.

When to Use This Skill

Use this skill when:

DevOps: Setting up CI/CD pipelines (GitHub Actions, GitLab CI, Jenkins), implementing GitOps workflows (ArgoCD, Flux)
AWS: Deploying to EC2, Lambda, ECS, EKS, managing S3, RDS, using CloudFormation/CDK
Azure: Working with Azure VMs, App Service, AKS, Azure Functions, Storage Accounts
GCP: Managing Compute Engine, GKE, Cloud Run, Cloud Storage, App Engine
Cloudflare: Deploying Workers, R2 storage, D1 databases, Pages applications
Kubernetes: Managing clusters, deployments, services, ingress, Helm charts, operators
Docker: Containerizing applications, multi-stage builds, Docker Compose, registries
FinOps: Analyzing cloud costs, optimizing spend, reserved instances, spot instances, rightsizing
DevSecOps: Security scanning (SAST/DAST), vulnerability management, secrets management, compliance
IaC: Terraform, CloudFormation, Pulumi, configuration management
Monitoring: Setting up observability, logging, metrics, alerting, distributed tracing

Platform Selection Guide

When to Use AWS

Best For:

General-purpose cloud computing at scale
Mature ecosystem with 200+ services
Enterprise workloads with compliance requirements
Hybrid cloud with AWS Outposts
Extensive third-party integrations
Advanced networking and security controls

Key Services:

EC2 (virtual machines, flexible compute)
Lambda (serverless functions, event-driven)
ECS/EKS (container orchestration)
S3 (object storage, industry standard)
RDS (managed relational databases)
DynamoDB (NoSQL, global tables)
CloudFormation/CDK (infrastructure as code)
IAM (identity and access management)
VPC (virtual private cloud networking)

Cost Profile: Pay-as-you-go, reserved instances (up to 72% discount), savings plans, spot instances (up to 90% discount)

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.

infra-engineer is a skill published in the GitHub repository ushibo/brigade (1 stars, last pushed 3mo ago), licensed MIT. It adds 294 tokens to every session and 5,816 once invoked, about $0.0012 per session on Opus 5.5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
