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.

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 | $0.00020 | $0.00389 |
| Opus 5 | $0.00010 | $0.00195 |
| Sonnet 5 | $0.00004 | $0.00078 |
| Haiku 4.5 | $0.00002 | $0.00039 |
Grade A, and why
web-auth-integrator 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 11d 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.
What it actually says
Web Auth Integrator
Objective
Implement authentication and authorization end-to-end based on
project-config.json.
Required Workflow
- Read
project-config.jsonand determine auth provider. - For Clerk:
- install
@clerk/nextjsor@clerk/clerk-react - wrap app with
ClerkProvider - protect routes with auth middleware
- configure Clerk webhooks
- install
- For Auth.js / NextAuth:
- configure providers (Google, GitHub, credentials)
- choose JWT or DB sessions
- protect API routes and pages
- For Supabase Auth:
- use
supabase.auth - configure OAuth providers
- configure magic links
- use
- For custom JWT:
- scaffold
/auth/register,/auth/login,/auth/refresh - hash passwords with bcrypt
- sign/verify JWTs (
joseorjsonwebtoken) - implement refresh-token rotation
- scaffold
- Implement RBAC middleware.
- Add CSRF protection and secure cookie flags (
HttpOnly,SameSite=Strict,Secure). - Output auth integration artifacts and
auth-report.json.

What ships with it
3 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.

web-auth-integrator is a skill published in the GitHub repository 0x-Professor/Agent-Skills-Hub (10 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 20 tokens to every session and 389 once invoked, about $0.0001 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 2026-08-31.
