atmos-imports

atmos-imports is a skill for Claude Code, Codex from cloudposse/atmos. It costs 44 tokens per session (897 once invoked), scanned A, original, Apache-2.0.

A configuration reuse system that imports local or remote stack files into an Atmos project. A stack file is a configuration file describing environments and the components they use.

In plain words
What is it for?
Use it to reuse defaults, regional settings, catalog entries, and other stack fragments from local files or remote GitHub and web locations.
Why use it?
It removes duplicated defaults and shared settings across environments. Imported files are configuration, not the source code for components.

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-imports 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 5d 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 Imports

Use this skill for stack manifest import: behavior, especially remote imports. Imports pull stack configuration, not component source code.

Import Basics

import:
  - catalog/vpc/defaults
  - mixins/region/us-east-2
  - orgs/acme/plat/prod/_defaults

Atmos resolves imports before producing the final stack. Use imports for _defaults.yaml, mixins, catalog defaults, reusable stack fragments, and remote stack configuration.

If both file.yaml and file.yaml.tmpl exist, the template version is preferred. Template imports can receive context and render before merge.

Remote Imports

Remote imports use the same stack import: key:

import:
  - https://raw.githubusercontent.com/acme/config/main/stacks/catalog/vpc.yaml
  - github://acme/config/main/stacks/catalog/eks.yaml
  - git::https://github.com/acme/config.git//stacks/catalog/db.yaml?ref=v1.2.3
  - s3::https://s3.amazonaws.com/acme-configs/stacks/catalog/vpc.yaml
  - gcs::gs://acme-configs/stacks/catalog/eks.yaml
  - oci://ghcr.io/acme/atmos-config:v1.2.3

Use pinned refs or immutable artifact tags for production imports. Prefer HTTPS/GitHub forms for read-only public config and Git/OCI forms when versioning, auth, or packaged artifacts matter.

Import vs Source vs Vendoring

  • import: pulls stack YAML configuration.
  • Component source: provisions component source code.
  • vendor.yaml plus atmos vendor pull materializes external files into the repository.

Remote imports do not create components/terraform/<name> directories. If a remote imported stack references a component whose source is not local, also configure component source: or vendor the component with atmos vendor pull.

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.
