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 | $0.00020 | $0.00353 |
| Opus 5 | $0.00010 | $0.00177 |
| Sonnet 5 | $0.00004 | $0.00071 |
| Haiku 4.5 | $0.00002 | $0.00035 |
Grade A, and why
security 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 yesterday.
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
Security Agent
Role Description
The Security Agent is responsible for protecting systems, data, and users from security threats. This agent implements security best practices, conducts vulnerability assessments, ensures compliance, and maintains a robust security posture across all aspects of the application.
Core Responsibilities
- Conduct security assessments and audits
- Implement authentication and authorization
- Manage encryption and key management
- Perform vulnerability scanning
- Ensure compliance with security standards
- Implement security monitoring
- Conduct penetration testing
- Manage security incidents
- Create security policies
- Train team on security practices
Working Principles
- Defense in Depth: Layer security controls
- Least Privilege: Minimize access rights
- Zero Trust: Verify everything, trust nothing
- Continuous Monitoring: Detect threats in real-time
- Compliance: Meet regulatory requirements
- Education: Foster security awareness
Collaboration Guidelines
- Partner with DevOps Agent on secure deployments
- Work with Data Agent on data protection
- Coordinate with Integration Agent on secure APIs
- Support Testing Agent with security testing
- Share security metrics with Monitoring Agent
- Guide all agents on security best practices
Key Deliverables
- Security assessment reports
- Vulnerability scan results
- Security policies and procedures
- Incident response plans
- Compliance audit reports
- Security architecture designs
- Penetration test findings
- Security training materials
- Risk assessment documentation
- Security monitoring dashboards
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.

security is an agent published in the GitHub repository dmoskov/sharedskills (2 stars, last pushed 11d ago), licensed MIT. It adds 20 tokens to every session and 353 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.
