atmos-init

atmos-init is a skill for Claude Code from cloudposse/atmos. It costs 35 tokens per session (1,214 once invoked), scanned A, original, Apache-2.0.

A project-bootstrap command that creates a new Atmos project from a built-in template. Templates provide starting layouts for general projects and cloud environments such as AWS, Google Cloud, and Azure.

In plain words
What is it for?
Use it to create a basic project, a cloud landing zone, or an AWS application project from a selected template.
Why use it?
It removes the need to assemble the initial folders, configuration, and workflow files by hand. The feature is experimental, so its behaviour may change.

About the project

Atmos is an infrastructure runtime that coordinates tools such as Terraform, OpenTofu, Kubernetes, Helm, Packer, Ansible, and containers through consistent commands and configuration. It is for teams running cloud infrastructure on laptops, in CI, or through AI agents across environments and regions. Its catalogue entries provide skills, agents, commands, and other add-ons for Atmos workflows.

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

atmos-init 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 3d 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.

Atmos Init

Use this skill for bootstrapping a brand-new Atmos project from the built-in template catalog via atmos init.

atmos init is a thin, project-bootstrap-scoped wrapper around the exact same engine atmos scaffold generate uses (pkg/generator/ui.InitUI). For authoring a new template — custom fields, conditional when: on fields/files, hooks — load atmos-scaffold instead; everything documented there (field types, conditional prompts/files, spec.hooks:, 3-way merge mechanics) applies unchanged to project templates consumed via init. This skill only covers what's specific to init.

Quick Shape

atmos init basic ./my-project
atmos init aws/landing-zone ./my-project
atmos init                          # interactive template + target selection

Built-in templates: basic (minimal cloud-agnostic layout), simple, atmos (atmos.yaml only), aws/app (SDLC repo: dev/staging/prod, native CI, emulator-enabled), aws/landing-zone, gcp/landing-zone, azure/landing-zone. Run atmos scaffold list to see all templates, including remote/catalog ones not built in.

atmos init ships experimental — behavior may change between releases.

Shared Template Contract

Every init template is an AtmosScaffoldConfig, so it uses the same contract as atmos scaffold generate: spec.fields, spec.files, and spec.hooks. Fields and files can use when: predicates or CEL expressions over earlier answers; generation hooks run at before.scaffold.generate or after.scaffold.generate. Scaffold hooks deliberately support only kind: step and ordered kind: steps, even though stack lifecycle hooks support more kinds.

Load atmos-scaffold before authoring or changing any of those template features. It contains the field, CEL, file-condition, hook, and template-context rules that init consumes unchanged.

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.
