cyber-agent: Agent for Claude Code

.claude/agents/redteam-agent.md

redteam-agent is an agent for Claude Code from waybarrios/cyber-agent. It costs 48 tokens per session (1,676 once invoked), scanned A, original, no licence file.

A red-team penetration-testing agent for the HTB Expressway target machine. Red-team testing is an authorised security exercise that tries to discover and exploit weaknesses, and it shows its attack plan before acting.

In plain words
What is it for?
Use it to perform reconnaissance, enumeration, exploitation, and privilege escalation against the specified HTB target.
Why use it?
It organises the stages of testing, from finding exposed services to gaining higher access, so the assessment follows a clear sequence.

Agent for Claude Code

Written for Claude Code: installed under .claude/. Also seen: model in frontmatter.

This is waybarrios/cyber-agent's own configuration. It tells Claude Code how to work on cyber-agent itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything cyber-agent configures →

Token cost

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.

Security

Grade A, and why

redteam-agent 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 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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

# Check sudo which sudo

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
