Atmos profiles: profile directories, --profile and ATMOSPROFILE activation, profile merge behavior, environment switching, and routing profile-specific auth/toolchain/config overrides

  • DevOps & Cloud work in your project
  • SKILL.md covers Purpose, Profile Layout, Profile Config and Routing, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Atmos Profiles is an agent skill from cloudposse/atmos. Atmos profiles: profile directories, --profile and ATMOSPROFILE activation, profile merge behavior, environment switching, and routing profile-specific auth/toolchain/config overrides

Its SKILL.md is about 650 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. 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

  • DevOps & Cloud work in your project

Example prompts

  • “Use the atmos-profiles skill to atmo profiles: profile directories, --profile and ATMOSPROFILE activation, profile merge behavior, environment…”
  • “/atmos-profiles”

What it can do on your machine

Read from SKILL.md and the folder at commit fbae93f. 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 yaml and bash).

    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 Profiles loads about 646 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 228 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~646

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 Profiles

Use this skill when configuring or troubleshooting Atmos profiles: named configuration overlays selected with --profile or ATMOS_PROFILE.

Purpose

Profiles let teams switch configuration contexts without changing the base project config. Use them for developer, CI, tenant, cloud account, or environment-specific overrides.

bash
atmos --profile developer terraform plan vpc -s dev
ATMOS_PROFILE=ci atmos terraform deploy vpc -s prod

Use --profile with no value in an interactive terminal to open a multi-select picker of every discovered profile. Non-interactive contexts (CI, scripts) must pass --profile=<name> or ATMOS_PROFILE explicitly.

Profile Layout

Keep profile files focused and aligned with the sections they override:

text
profiles/
  developer/
    atmos.yaml
    auth.yaml
  ci/
    atmos.yaml
    auth.yaml

Profile configuration is merged into the active Atmos configuration. Put shared defaults in the base config, then keep each profile to the smallest override needed.

Profile Config

Configure the profile search location in root config when the default location is not sufficient:

yaml
profiles:
  base_path: profiles

Example profiles/ci/auth.yaml override:

yaml
auth:
  providers:
    github-oidc:
      kind: github/oidc
      region: us-east-1
  identities:
    deploy:
      kind: aws/assume-role
      via:
        provider: github-oidc

Routing

Auth providers, identities, OIDC, SSO, keyring in profilesatmos-auth
CI use of ATMOS_PROFILEatmos-ci
Tool versions or registries that differ by profileatmos-toolchain
Base paths and profile-relative file layoutatmos-project-layout

Guardrails

  • Keep profile overrides small and predictable; avoid duplicating the whole base atmos.yaml.
  • Use the same provider and identity names across profiles when callers should not care which profile is active.
  • Prefer ATMOS_PROFILE in CI and --profile for one-off local commands.
  • Verify the active merged configuration with atmos describe config or the relevant atmos describe component command.
