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 | $0.00050 | $0.01027 |
| Opus 5 | $0.00025 | $0.00513 |
| Sonnet 5 | $0.00010 | $0.00205 |
| Haiku 4.5 | $0.00005 | $0.00103 |
Grade A, and why
cybersecurity-expert 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 4d 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.

Cybersecurity Expert
Build comprehensive cybersecurity solutions including threat detection, incident response, vulnerability management, and security compliance monitoring.
Learning Objectives
- Master security information and event management (SIEM)
- Understand threat detection and incident response
- Implement vulnerability management programs
- Apply security compliance frameworks
- Navigate security operations center (SOC) workflows
Prerequisites
- Understanding of network security fundamentals
- Knowledge of security frameworks and standards
- Familiarity with common attack vectors
- Experience with security tools and technologies
Core Concepts
Security Information & Event Management (SIEM)
Centralized platforms that aggregate, analyze, and correlate security logs and events from across infrastructure to detect threats, investigate incidents, and maintain compliance.
Threat Detection & Intelligence
Proactive identification of security threats using behavioral analysis, indicators of compromise (IOCs), threat feeds, and machine learning to detect anomalies and potential attacks.
Incident Response
Structured approach to handling security breaches and cyberattacks including preparation, detection, containment, eradication, recovery, and post-incident analysis.
Vulnerability Management
Systematic identification, classification, prioritization, remediation, and mitigation of security vulnerabilities in systems, applications, and infrastructure.
Security Compliance
Ensuring organizational adherence to security standards and regulations like GDPR, HIPAA, PCI-DSS, SOC 2, ISO 27001 through controls, audits, and documentation.
Best Practices
SIEM Operations
- Centralize log collection from all critical systems
- Normalize and enrich event data
- Define clear alert escalation criteria
- Tune correlation rules to reduce false positives
- Maintain threat intelligence feeds
- Regular review and update of detection rules
- Archive logs for forensic analysis
What ships with it
1 file 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.

cybersecurity-expert is a skill published in the GitHub repository personamanagmentlayer/pcl (40 stars, last pushed 2d ago), licensed Apache-2.0. It adds 50 tokens to every session and 1,027 once invoked, about $0.0003 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 2026-09-05.
