What it does

Atmos AWS Eks is an agent skill from cloudposse/atmos. AWS EKS commands in Atmos: atmos aws eks update-kubeconfig, atmos aws eks token, kubeconfig generation, kubectl exec credentials, EKS auth integrations

Its SKILL.md is about 830 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in DevOps & Cloud, covering Container orchestration. It works with Amazon Web Services and Kubernetes. The repository describes itself as: Atmos is the open-source runtime for infrastructure — it builds, authenticates, and ships Terraform, OpenTofu, Packer, Ansible, Kubernetes, Helm, and containers the same way on… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Container orchestration

Example prompts

  • “/atmos-aws-eks”

What it can do on your machine

Read from SKILL.md and the folder at commit 36726ae. 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 (its code samples are bash and yaml).

    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

Atmos AWS Eks loads about 828 tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 271 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~828

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.

Atmos AWS EKS

Use this skill for Atmos commands that connect AWS EKS clusters to local Kubernetes tooling. It owns atmos aws eks update-kubeconfig and atmos aws eks token.

Command Model

atmos aws eks update-kubeconfig writes or prints kubeconfig entries for an EKS cluster. It can run from explicit CLI arguments, a component and stack, an auth.integrations entry, or an Atmos identity with explicit cluster details.

shell
atmos aws eks update-kubeconfig <component> -s <stack>
atmos aws eks update-kubeconfig --profile dev --name dev-cluster
atmos aws eks update-kubeconfig --integration dev/eks/primary
atmos aws eks update-kubeconfig --name dev-cluster --region us-east-2 --identity dev-admin

atmos aws eks token generates a Kubernetes ExecCredential token for kubectl. It is normally called by kubectl from generated kubeconfig rather than run by humans.

shell
atmos aws eks token --cluster-name dev-cluster --region us-east-2 --identity dev-admin

Configuration

For integration mode, configure an aws/eks integration in auth.integrations. Route provider, identity, AWS SSO, SAML, OIDC, assume role, and assume root details to atmos-auth.

yaml
auth:
  providers:
    company-sso:
      kind: aws/iam-identity-center
      region: us-east-1
      start_url: https://company.awsapps.com/start/

  identities:
    dev-admin:
      kind: aws/permission-set
      via:
        provider: company-sso
      principal:
        name: AdministratorAccess
        account: dev

  integrations:
    dev/eks/primary:
      kind: aws/eks
      via:
        identity: dev-admin
      spec:
        cluster:
          name: dev-cluster
          region: us-east-2
          alias: dev-eks

Agent Guidance

  • Prefer --integration when a named EKS integration exists; it centralizes cluster name, region, alias, and identity selection.
  • Use --identity with --name and --region for ad hoc kubeconfig generation through Atmos Auth.
  • Use --profile or --role-arn only when the workflow intentionally relies on AWS CLI-style credentials rather than Atmos Auth. In this command, --profile means the AWS CLI/kubeconfig credential profile, not an Atmos profile, --identity, or --integration.
  • Use --dry-run when reviewing kubeconfig output or avoiding writes to the user's kubeconfig.
  • Do not hard-code kubeconfig paths unless the repo already has a convention. Check components.helmfile.kubeconfig_path and Helmfile settings first when using component/stack mode.
  • If the AWS CLI or kubectl must be installed for a scripted job, route tool installation to atmos-toolchain.
