A guide for signing the agent in to GitHub using Git or GitHub's command-line tool. It covers access tokens, SSH keys, saved credentials, and checking which method is available.

Use it before cloning repositories, pushing code, managing pull requests, issues, or CI workflows on GitHub.

It removes the setup work that prevents an agent from accessing private repositories or working with GitHub. It also provides a fallback when the GitHub command-line tool is not installed.

github-auth — Skill for Claude Code and Codex by braxtonROSE4

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.

Any agent

npx skills add braxtonROSE4/zorro-agent --skill github-auth

Token cost

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	$0.00048	$0.01965
Opus 5	$0.00024	$0.00983
Sonnet 5	$0.00010	$0.00393
Haiku 4.5	$0.00005	$0.00197

Security

Grade A, and why

github-auth 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 9d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/gh-env.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 247 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitHub Authentication Setup

This skill sets up authentication so the agent can work with GitHub repositories, PRs, issues, and CI. It covers two paths:

git (always available) — uses HTTPS personal access tokens or SSH keys
gh CLI (if installed) — richer GitHub API access with a simpler auth flow

Detection Flow

When a user asks you to work with GitHub, run this check first:

# Check what's available
git --version
gh --version 2>/dev/null || echo "gh not installed"

# Check if already authenticated
gh auth status 2>/dev/null || echo "gh not authenticated"
git config --global credential.helper 2>/dev/null || echo "no git credential helper"

Decision tree:

If gh auth status shows authenticated → you're good, use gh for everything
If gh is installed but not authenticated → use "gh auth" method below
If gh is not installed → use "git-only" method below (no sudo needed)

Method 1: Git-Only Authentication (No gh, No sudo)

This works on any machine with git installed. No root access needed.

Option A: HTTPS with Personal Access Token (Recommended)

This is the most portable method — works everywhere, no SSH config needed.

Step 1: Create a personal access token

Tell the user to go to: https://github.com/settings/tokens

Click "Generate new token (classic)"
Give it a name like "zorro-agent"
Select scopes:
- repo (full repository access — read, write, push, PRs)
- workflow (trigger and manage GitHub Actions)
- read:org (if working with organization repos)
Set expiration (90 days is a good default)
Copy the token — it won't be shown again

Step 2: Configure git to store the token

# Set up the credential helper to cache credentials
# "store" saves to ~/.git-credentials in plaintext (simple, persistent)
git config --global credential.helper store

# Now do a test operation that triggers auth — git will prompt for credentials
# Username: <their-github-username>
# Password: <paste the personal access token, NOT their GitHub password>
git ls-remote https://github.com/<their-username>/<any-repo>.git

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.
