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 | $0.00044 | $0.01421 |
| Opus 5 | $0.00022 | $0.00711 |
| Sonnet 5 | $0.00009 | $0.00284 |
| Haiku 4.5 | $0.00004 | $0.00142 |
Grade A, and why
configuring-multi-factor-authentication-with-duo 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 6d 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.

Configuring Multi-Factor Authentication with Duo
Overview
Deploy Cisco Duo multi-factor authentication across enterprise applications, VPN, RDP, and SSH access points. This skill covers Duo integration methods, adaptive authentication policies, device trust assessment, and phishing-resistant MFA deployment aligned with NIST 800-63B AAL2/AAL3 requirements.
When to Use
- When deploying or configuring configuring multi factor authentication with duo 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
- Familiarity with identity access management concepts and tools
- Access to a test or lab environment for safe execution
- Python 3.8+ with required dependencies installed
- Appropriate authorization for any testing activities
Objectives
- Configure Duo MFA for VPN, RDP, SSH, and web applications
- Implement adaptive access policies based on user, device, and network context
- Deploy phishing-resistant authentication (Duo Verified Push, WebAuthn)
- Configure device health policies (trusted endpoints, OS version enforcement)
- Set up Duo Admin Panel monitoring and reporting
- Implement MFA bypass and emergency access procedures
Key Concepts
Duo Authentication Methods (by security strength)
- Security Keys (WebAuthn/FIDO2): Phishing-resistant, AAL3 capable
- Duo Verified Push: Requires code entry, resistant to MFA fatigue attacks
- Duo Push: Push notification to Duo Mobile app
- TOTP (Duo Mobile Passcode): Time-based one-time password
- Hardware Tokens: OTP from physical token
- SMS/Phone Call: Least secure, use only as fallback
Duo Integration Architecture
- Duo Authentication Proxy: On-premises proxy for RADIUS/LDAP integration
- Duo Web SDK: Embed Duo MFA in web applications
- Duo OIDC/SAML: SSO integration for cloud applications
- Duo for RDP: Windows Logon MFA
- Duo Unix: PAM-based MFA for SSH
What ships with it
7 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.

configuring-multi-factor-authentication-with-duo is a skill published in the GitHub repository 26zl/cybersec-toolkit (51 stars, last pushed yesterday), licensed MIT. It adds 44 tokens to every session and 1,421 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 2026-09-03.
