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.

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 | $0.00043 | $0.01194 |
| Opus 5 | $0.00022 | $0.00597 |
| Sonnet 5 | $0.00009 | $0.00239 |
| Haiku 4.5 | $0.00004 | $0.00119 |
Grade A, and why
nuxt-better-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 10d 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.

Nuxt Better Auth
Authentication module for Nuxt 4+ built on Better Auth. Provides composables, server utilities, and route protection.
Package rename: this module moved to the official
nuxt-modulesorg. The package is@nuxtjs/better-auth(>=0.1.4); the old@onmax/nuxt-better-authis frozen at 0.1.2. Docs: https://better-auth.nuxt.dev
better-authitself is a hard peer at>=1.7.1 <2.
When to Use
- Installing/configuring
@nuxtjs/better-auth - Implementing login/signup/signout flows
- Protecting routes (client and server)
- Accessing user session in API routes
- Integrating Better Auth plugins (admin, passkey, 2FA)
- Setting up database with NuxtHub
- Using clientOnly mode for external auth backends
- Adding i18n support with
@nuxtjs/i18n
For Nuxt patterns: use nuxt skill
For NuxtHub database: use nuxthub skill

What ships with it
8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

nuxt-better-auth is a skill published in the GitHub repository YuDefine/nuxt-supabase-starter (45 stars, last pushed today), licensed MIT. It adds 43 tokens to every session and 1,194 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
