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 | $0.00046 | $0.00733 |
| Opus 5 | $0.00023 | $0.00367 |
| Sonnet 5 | $0.00009 | $0.00147 |
| Haiku 4.5 | $0.00005 | $0.00073 |
Grade A, and why
nuxt-auth-utils 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.

Nuxt Auth Utils
Cookie-based authentication module for Nuxt. No database required for session storage — sessions are encrypted and stored in cookies.
When to Use
- Installing/configuring
nuxt-auth-utils - Implementing OAuth login flows (Google, GitHub, etc.)
- Protecting routes (client and server)
- Accessing user session in API routes
- Setting up session types
For Nuxt patterns: use nuxt skill
For better-auth (DB-based auth): use nuxt-better-auth skill
Available Guidance
| File | Topics |
|---|---|
| references/client-auth.md | useUserSession, OAuth login, logout, session state |

Key Concepts
| Concept | Description |
|---|---|
useUserSession() |
Client composable — user, loggedIn, session, fetch, clear |
requireUserSession() |
Server helper — throws 401 if not authenticated |
setUserSession() |
Server helper — set session after OAuth success |
clearUserSession() |
Server helper — clear session (logout) |
defineOAuth*EventHandler |
Server OAuth callback handlers |
auth.d.ts |
Type augmentation via declare module '#auth-utils' |
What ships with it
2 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-auth-utils is a skill published in the GitHub repository YuDefine/nuxt-supabase-starter (45 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 733 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.
