Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00040 | $0.02371 |
| Opus 5 | $0.00020 | $0.01185 |
| Sonnet 5 | $0.00008 | $0.00474 |
| Haiku 4.5 | $0.00004 | $0.00237 |
Grade A, and why
building-red-team-c2-infrastructure-with-havoc scanned grade A with 1 finding 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 9d 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.
Asks for rootlowPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
sudo apt update Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Building Red Team C2 Infrastructure with Havoc
Overview
Havoc is a modern, open-source post-exploitation command and control (C2) framework created by C5pider. It provides a collaborative multi-operator interface similar to Cobalt Strike, featuring the Demon agent for Windows post-exploitation, customizable profiles for traffic malleable configurations, and support for HTTP/HTTPS/SMB listeners. This skill covers deploying production-grade Havoc C2 infrastructure with proper OPSEC considerations for authorized red team engagements.
Prerequisites
- Ubuntu 22.04 LTS or Debian 11+ (for Teamserver)
- Kali Linux 2023+ (for Client)
- VPS providers: DigitalOcean, Linode, or AWS EC2 (minimum 2GB RAM, 2 vCPU)
- Domain name aged 30+ days with valid SSL certificate
- Written authorization for red team engagement

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.
