Calls gh and brew

What it does

Setup is an agent skill from fcakyon/claude-codex-settings. This skill should be used when the user asks "how to setup GitHub CLI", "configure gh", "gh auth not working", "GitHub CLI connection failed", "gh CLI error", or needs help with GitHub authentication.

Its SKILL.md is about 250 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 Backend & APIs, covering Authentication. It works with GitHub. The repository describes itself as: Battle-tested Claude Code, OpenAI Codex, Cursor configs, plugins, hooks and agents with Kimi, MiniMax and GLM API support. The licence is Apache-2.0.

When your agent uses it

Asks how to setup GitHub CLI
Gh auth not working
GitHub CLI connection failed
Needs help with GitHub authentication

Example prompts

“how to setup GitHub CLI”
“configure gh”
“gh auth not working”
“/setup”

Workflow steps

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

Check authentication - gh auth status
Re-login if needed - gh auth login
Check scopes - Ensure the token has repo access
Refresh auth - gh auth refresh
Update gh - brew upgrade gh or equivalent

What it can do on your machine

Read from SKILL.md and the folder at commit a035b4e. 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
No URLs in SKILL.md. Its commands use gh, which can reach the network depending on how they are called.
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

Setup loads about 253 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 94 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~52
When it runs · the whole SKILL.md, loaded when a task matches: ~253

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

The full file from fcakyon/claude-codex-settings at commit a035b4e, republished under its Apache-2.0 licence (© fcakyon). 94 words, ~253 tokens.

description: This skill should be used when the user asks "how to setup GitHub CLI", "configure gh", "gh auth not working", "GitHub CLI connection failed", "gh CLI error", or needs help with GitHub authentication.

GitHub CLI Setup

Configure gh CLI for GitHub access.

Check Current Status

bash

gh auth status

Report one of these states:

gh is not authenticated and needs login
gh is authenticated, including the current username if available

If authentication is missing or broken, guide the user through:

bash

gh auth login

Select: GitHub.com -> HTTPS -> Login with browser

Verify Authentication

bash

gh auth status
gh api user --jq '.login'

Troubleshooting

If gh commands fail:

Check authentication - gh auth status
Re-login if needed - gh auth login
Check scopes - Ensure the token has repo access
Refresh auth - gh auth refresh
Update gh - brew upgrade gh or equivalent
