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.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 8 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00042 | $0.04583 |
| Opus 5 | $0.00021 | $0.02292 |
| Sonnet 5 | $0.00008 | $0.00917 |
| Haiku 4.5 | $0.00004 | $0.00458 |
Grade A, and why
atmos-terraform 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.
How it starts
The opening of the file, as written. The whole thing — 484 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Atmos Terraform and OpenTofu Orchestration
Atmos wraps the Terraform or OpenTofu CLI to provide stack-aware orchestration of infrastructure operations. Instead of manually managing workspaces, backends, variable files, and authentication for each component, Atmos resolves the full configuration from stack manifests and handles all of these concerns automatically.
Everything in this skill applies identically to Terraform and OpenTofu. The atmos terraform command
namespace is the same regardless of which binary is configured -- atmos terraform plan runs tofu plan when
the binary is set to tofu. Use the user's terminology in responses (if they say "OpenTofu," say "OpenTofu").
Terraform or OpenTofu: Binary Selection
Atmos defaults to the terraform binary. Switch to OpenTofu by setting components.terraform.command: tofu
in atmos.yaml. The setting cascades through CLI > env > config > defaults precedence and can be overridden
at multiple levels for mixed setups.
Global (whole project on OpenTofu)
# atmos.yaml
components:
terraform:
command: tofu # All atmos terraform commands invoke `tofu` instead of `terraform`
base_path: components/terraform
Or via environment variable:
export ATMOS_COMPONENTS_TERRAFORM_COMMAND=tofu
atmos terraform plan vpc -s dev # Runs: tofu plan
Per-stack override
Use terraform.overrides.command in a stack manifest to switch the binary for everything in that stack:
# stacks/orgs/acme/plat/prod/_defaults.yaml
terraform:
overrides:
command: tofu
Per-component override
Set command on an individual component to run a single component on a different binary than the rest of
the stack (useful for legacy components that haven't been validated on OpenTofu, or new components testing
OpenTofu-specific features):
components:
terraform:
legacy-vpc:
command: terraform # This component stays on Terraform
vars: ...
new-eks:
command: tofu # This component runs on OpenTofu
vars: ...
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

atmos-terraform is a skill published in the GitHub repository cloudposse/atmos (1,375 stars, last pushed today), licensed Apache-2.0. It adds 42 tokens to every session and 4,583 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
