gh-auth-isolation

gh-auth-isolation is a skill for Claude Code, Codex from bradygaster/squad. It costs 20 tokens per session (1,543 once invoked), scanned A, a copy of gh-auth-isolation, MIT.

A procedure for using more than one GitHub account safely, such as a work-managed account and a personal account. It explains how to check the active identity and obtain the token for a specific account.

In plain words
What is it for?
Checking GitHub login status, selecting the intended account, pushing to personal forks, and working with repositories outside a company organization.
Why use it?
Coding agents can otherwise use the wrong account when pushing code, opening pull requests, or accessing repositories. The procedure helps prevent credentials and actions from crossing between work and personal accounts.

About the project

bradygaster/squad is a tool that creates a human-directed team of AI development agents inside a project repository through GitHub Copilot. Developers use it to delegate work among persistent specialists such as frontend, backend, testing, and lead agents while retaining responsibility for decisions and review. The catalogue entries are the skills, agents, and instructions that define and coordinate those team members.

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.

Security

Grade A, and why

gh-auth-isolation 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 5d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 184 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context

Many developers use GitHub through an Enterprise Managed User (EMU) account at work while maintaining a personal GitHub account for open-source contributions. AI agents spawned by Squad inherit the shell's default gh authentication — which is usually the EMU account. This causes failures when agents try to push to personal repos, create PRs on forks, or interact with resources outside the enterprise org.

This skill teaches agents how to detect the active identity, switch contexts safely, and avoid mixing credentials across operations.

Patterns

Detect Current Identity

Before any GitHub operation, check which account is active:

gh auth status

Look for:

  • Logged in to github.com as USERNAME — the active account
  • Token scopes: ... — what permissions are available
  • Multiple accounts will show separate entries

Extract a Specific Account's Token

When you need to operate as a specific user (not the default):

# Get the personal account token (by username)
gh auth token --user personaluser

# Get the EMU account token
gh auth token --user corpalias_enterprise

Use case: Push to a personal fork while the default gh auth is the EMU account.

Push to Personal Repos from EMU Shell

The most common scenario: your shell defaults to the EMU account, but you need to push to a personal GitHub repo.

# 1. Extract the personal token
$token = gh auth token --user personaluser

# 2. Push using token-authenticated HTTPS
git push https://personaluser:[email protected]/personaluser/repo.git branch-name

Why this works: gh auth token --user reads from gh's credential store without switching the active account. The token is used inline for a single operation and never persisted.

Create PRs on Personal Forks

When the default gh context is EMU but you need to create a PR from a personal fork:

# Option 1: Use --repo flag (works if token has access)
gh pr create --repo upstream/repo --head personaluser:branch --title "..." --body "..."

# Option 2: Temporarily set GH_TOKEN for one command
$env:GH_TOKEN = $(gh auth token --user personaluser)
gh pr create --repo upstream/repo --head personaluser:branch --title "..."
