At a glance

Ensure GitHub CLI (gh) is installed and authenticated before running gh commands; guide the user to configure it if not

  • Works in 2 steps: Check installation and auth: Run gh auth… → If gh auth status succeeds: Proceed with…
  • Calls gh and brew

What it does

Check GitHub CLI is an agent skill from blockscout/frontend. Ensure GitHub CLI (gh) is installed and authenticated before running gh commands; guide the user to configure it if not

Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It works with GitHub. The repository describes itself as: Front-end application for Blockscout chain explorer.

Example prompts

  • “/check-github-cli”

Workflow steps

2 steps, taken from the first numbered list in SKILL.md.

  1. Check installation and auth: Run gh auth status. If it reports "not logged in" or the command is not found
  2. If gh auth status succeeds: Proceed with the steps that require gh.

What it can do on your machine

Read from SKILL.md and the folder at commit 9438622. 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

    Shell commands in SKILL.md call:

    • gh
    • brew

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Links to these hosts (documentation or services it may open):

    • cli.github.com

    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

Check GitHub CLI loads about 345 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 185 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~345

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 185 words (~345 tokens).

“Use this skill whenever a workflow or command requires the GitHub CLI (gh). Before running any gh commands:”
