boring-ui: Skill for Claude Code

.agents/skill-library/boring-google-signup-setup/SKILL.md

boring-google-signup-setup is a skill for Claude Code, Codex from hachej/boring-ui. It costs 59 tokens per session (1,865 once invoked), scanned A, original, MIT.

A setup guide for enabling Google sign-up and sign-in in a child application that already uses the shared @hachej/boring-core authentication system. Google OAuth is a way for users to authenticate with their Google account.

In plain words
What is it for?
Use it to configure Google OAuth credentials, set BETTER_AUTH and Google environment variables, enable the feature flag, and verify the child app’s setup.
Why use it?
It explains which Google credentials, environment settings, and feature flag are needed, while keeping Google authentication inside the existing authentication system.

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

boring-google-signup-setup 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.

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.

Boring Google Signup Setup

This skill is the child-app setup contract for the plan in docs/plans/archive/google-signup-child-app-plan.md. Use it to teach or verify the shipped child-app setup shape for Google signup.

Goal

When using this skill, default to giving the user a short manual to-do list for the Google-side setup plus the exact app config/env changes they must make.

Do not imply that normal Google Sign-In web OAuth client creation is cleanly supported by gcloud/Terraform here. Treat Google-side client creation as a manual Console task unless the user explicitly asks for a brittle browser-automation workaround.

Turn on Google signup/signin for a child app with:

  1. Google OAuth credentials
  2. the existing better-auth core envs: BETTER_AUTH_SECRET, BETTER_AUTH_URL, CORS_ORIGINS
  3. two Google env vars: GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET
  4. one feature flag: features.google_oauth = true
  5. no auth-page fork unless the app wants custom branding

Assumed child-app contract

Core auth already runs on better-auth. Google is one provider inside that existing core auth stack, not a second auth system.

Core exposes Google signup when all of these are true:

  • GOOGLE_CLIENT_ID is set
  • GOOGLE_CLIENT_SECRET is set
  • features.google_oauth = true in boring.app.toml

If any one is missing, the app still boots and the Google button stays hidden.

There is no GOOGLE_OAUTH env flag in this first pass.

Why this setup is simple

This feature is intentionally narrow:

  • Google is enabled by one app-level TOML flag plus credentials
  • stock core auth pages gain the button automatically
  • invite signup stays on the existing email-only path
  • branded child apps reuse GoogleAuthButton

That keeps the first pass easy to teach and hard to break.

Quick path

1. Create Google OAuth credentials

This step is currently a manual Google Cloud Console to-do, not a normal gcloud automation step for this skill.
