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 | $0.02900 |
| Opus 5 | $0.00023 | $0.01450 |
| Sonnet 5 | $0.00009 | $0.00580 |
| Haiku 4.5 | $0.00005 | $0.00290 |
Grade D, and why
deploying-tailscale-for-zero-trust-vpn scanned grade D with 3 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 8d 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.

Deploying Tailscale for Zero Trust VPN
Overview
Tailscale is a zero trust mesh VPN built on WireGuard that creates encrypted peer-to-peer connections between devices without requiring traditional VPN servers or complex network configuration. Every connection in a Tailscale network (tailnet) is end-to-end encrypted using WireGuard's Noise protocol framework with Curve25519 key exchange. Tailscale implements zero trust networking by authenticating every connection request through identity providers, enforcing granular Access Control Lists (ACLs), and supporting features like exit nodes, subnet routers, MagicDNS, and Tailscale SSH. For organizations preferring self-hosted infrastructure, Headscale provides an open-source implementation of the Tailscale control server.
When to Use
- When deploying or configuring deploying tailscale for zero trust vpn capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation
Prerequisites
- Identity provider (Okta, Azure AD, Google Workspace, GitHub, or OIDC-compatible)
- Devices running supported OS (Linux, Windows, macOS, iOS, Android, FreeBSD)
- Administrative access to configure DNS and firewall rules
- Understanding of WireGuard protocol fundamentals
- Network planning documentation for subnet routing requirements

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.

deploying-tailscale-for-zero-trust-vpn is a skill published in the GitHub repository 26zl/cybersec-toolkit (54 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 2,900 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it D with 3 findings (asks for root, downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
