What it does

Cloud Infrastructure is an agent skill from cbrock84/headcount. Designs and runs cloud infrastructure — environments, infrastructure as code, networking and isolation, scaling, and cost. Use this to design a cloud environment, control infrastructure spend, set up environment separation, plan for scale or region failure, or review infrastructure someone configured by hand.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/sources.md`).

It sits in DevOps & Cloud, covering Infrastructure as code. The repository describes itself as: An agent organization structured as a company — 15+ departments, 125+ skills, each independently installable, citing the standards and regulators that settle the question. Runs… The licence is MIT.

When your agent uses it

  • Tasks that involve Infrastructure as code

Example prompts

  • “Use the cloud-infrastructure skill to design and runs cloud infrastructure — environments, infrastructure as code, networking and isolation…”
  • “/cloud-infrastructure”

What it can do on your machine

Read from SKILL.md and the folder at commit 98d1c17. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cloud Infrastructure loads about 1.1k tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 83 tokens; SKILL.md has 584 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~83
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Designs and runs cloud infrastructure — environments, infrastructure as code, networking and isolation, scaling, and cost. Use this to design a cloud environment, control infrastructure spend, set up environment separation, plan for scale or region failure, or review infrastructure someone configured by hand.

Cloud infrastructure

Cloud replaces capital cost with an operating cost that scales with carelessness. The discipline is mostly about making the environment reproducible and the spend visible.

Everything reproducible from code

Infrastructure created by hand cannot be reviewed, reproduced, or recovered. Define it as code, review it like code, and apply it through a pipeline rather than from a laptop.

The test: could you rebuild the environment from an empty account, and do you know that because you have done it? Untested reproducibility is a belief.

Console access for humans should be read-only in production by default. Write access exists for emergencies, is time-bound, and is logged — see security:access-and-identity for the policy this implements.

Environments that mean something

Separate environments by blast radius, not by name. Separate accounts or subscriptions give a hard boundary; separate namespaces in one account give a soft one that a misconfigured permission crosses.

Production data does not belong in lower environments. Where realistic data is needed, mask or synthesize it — a copied production database is a breach waiting for a misconfigured bucket, and it is one of the most common ways personal data escapes.

Networking and isolation

Default deny, then open what is needed. Public exposure should be a deliberate, reviewable act rather than the residue of a default.

Keep the trust boundary explicit and few: what is reachable from the internet, what is reachable between services, what reaches data stores. Most cloud incidents are not exotic — they are a storage bucket, a database, or a management interface that was reachable and should not have been.

Scaling and failure

Scale horizontally where you can and know your actual limits — the database connection ceiling, the third-party rate limit, the single-threaded component nobody remembers. Autoscaling in front of a hard downstream limit converts a slow system into an outage.

Design for the failure of a single instance and a single zone as routine. Region failure is a business continuity decision with a real price attached, made with operations:business-continuity-and-resilience rather than assumed by engineering.

Cost

Cost is an architectural property. Attribute spend by team and workload from the start; without tagging, cost becomes an unattributable aggregate that only ever gets addressed in a panic.

The usual large wins are unglamorous: idle non-production resources, over-provisioned instances, storage nobody deleted, and cross-zone data transfer nobody accounted for.

Sources

references/sources.md in this skill lists the outside authorities that settle the questions here — what each one is authoritative for, and what you may do with it. Check them before answering on anything they cover, and cite what you used. Most are free to read and not free to reproduce; the use note on each is binding.

Tooling

Platforms: AWS, Google Cloud, Microsoft Azure, and similar; managed application platforms — Fly.io, Render, Vercel, Railway — remove most of this work and are the right answer more often than engineering pride admits.

Orchestration where you need it: Kubernetes with a managed control plane, or a container service like ECS. Kubernetes is a platform team's worth of work; adopt it when you have the team.

Infrastructure as code and secrets: Terraform, OpenTofu, Pulumi, and similar, with secrets in a managed store rather than in the state file. it-operations:cloud-administration covers the corporate cloud estate, which is a different problem with overlapping tools.

Never

  • Make a production change by hand that is not reflected in code.
  • Put production data in a lower environment unmasked.
  • Autoscale a tier in front of a hard downstream limit.
  • Run without cost attribution until the bill forces it.

Can I use Cloud Infrastructure in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add cbrock84/headcount --skill cloud-infrastructure -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cloud-infrastructure, .gemini/skills/cloud-infrastructure, .github/skills/cloud-infrastructure and .opencode/skills/cloud-infrastructure in your project.

What does Cloud Infrastructure need to run?

SKILL.md names no scripts, command-line tools or credentials: Cloud Infrastructure is instructions for the agent only.

Does Cloud Infrastructure access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Cloud Infrastructure safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
