What it does

Atmos Asciicast is an agent skill from cloudposse/atmos. Create and review portable Atmos CLI asciicast demos for community-facing documentation, examples, and training materials.

Its SKILL.md is about 180 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/atmos-asciicast-authoring.md`).

It sits in Education, covering Training and onboarding materials. 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 Training and onboarding materials

Example prompts

  • “/atmos-asciicast”

What it can do on your machine

Read from SKILL.md and the folder at commit 110e139. 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.

    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 Asciicast loads about 182 tokens when it runs, and up to ~803 if it reads all its reference files. Until then it costs about 35 tokens; SKILL.md has 68 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~35
When it runs · the whole SKILL.md, loaded when a task matches
~182
With references · SKILL.md plus every file in references/, read only if the agent opens them
~803

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 Asciicast Skill

Use this skill when creating or reviewing .cast recordings that demonstrate Atmos CLI usage for a broad community audience.

This is a distributed Agent Skill. Keep it portable and audience-neutral. Do not assume Cloud Posse repository paths, the Atmos documentation website, or internal development fixtures unless the project using the skill explicitly provides those conventions.
