github-multi-account

A set of Rails instructions for building passwordless sign-in without the Devise authentication library. It uses passkeys as the main method and magic links as a fallback.

In plain words
What is it for?
Use it when adding or changing Rails authentication, including passkeys, magic links, session management, and password resets. It does not cover user permissions or authorization.
Why use it?
It provides a defined approach for login, sessions, passkey credentials, and password recovery without adding Devise or its larger set of conventions.

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

github-multi-account 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 2d 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.

Origin

GitHub Multi-Account — AI-Driven Setup

When to Activate

When the user has multiple GitHub accounts (check with gh auth status). If you see 2+ accounts listed, this skill applies.

What to Do (as the AI agent)

Step 1: Detect accounts

Run: gh auth status Look for multiple accounts. Note which usernames are listed.

Step 2: Ask the user

Ask: "I see you have multiple GitHub accounts: {list them}. Which one is your personal account and which is your work/EMU account?"

Step 3: Run the setup automatically

Once the user confirms, do ALL of this for them:

# 1. Define the functions
$personal = "THEIR_PERSONAL_USERNAME"
$work = "THEIR_WORK_USERNAME"

# 2. Add to PowerShell profile
$profilePath = $PROFILE.CurrentUserAllHosts
if (!(Test-Path $profilePath)) { New-Item -Path $profilePath -Force | Out-Null }
$existing = Get-Content $profilePath -Raw -ErrorAction SilentlyContinue
if ($existing -notmatch "gh-personal") {
    $block = @"

# === GitHub Multi-Account Aliases ===
function gh-personal { gh auth switch --user $personal 2>`$null | Out-Null; gh @args }
function gh-work { gh auth switch --user $work 2>`$null | Out-Null; gh @args }
Set-Alias ghp gh-personal
Set-Alias ghw gh-work
"@
    Add-Content -Path $profilePath -Value $block
}

# 3. Create CMD wrappers
$binDir = Join-Path $env:USERPROFILE ".squad\bin"
if (!(Test-Path $binDir)) { New-Item -ItemType Directory -Path $binDir -Force | Out-Null }
"@echo off`ngh auth switch --user $personal >nul 2>&1`ngh %*" | Out-File "$binDir\ghp.cmd" -Encoding ascii
"@echo off`ngh auth switch --user $work >nul 2>&1`ngh %*" | Out-File "$binDir\ghw.cmd" -Encoding ascii

# 4. Add to PATH
$userPath = [Environment]::GetEnvironmentVariable("PATH", "User")
if ($userPath -notmatch [regex]::Escape($binDir)) {
    [Environment]::SetEnvironmentVariable("PATH", "$binDir;$userPath", "User")
    $env:PATH = "$binDir;$env:PATH"
}

# 5. Load in current session
function gh-personal { gh auth switch --user $personal 2>$null | Out-Null; gh @args }
function gh-work { gh auth switch --user $work 2>$null | Out-Null; gh @args }
Set-Alias ghp gh-personal
Set-Alias ghw gh-work

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.
