A coding-agent skill that turns your agent into a security auditor. It orchestrates multiple parallel agents through a six-phase pipeline -- recon, hunting, validation, reporting, structured output, and independent verification -- to find exploitable vulnerabilities with real impact.

Our Nethemba colleague John wrote the new anonymization proxy for LLMs:

A reversible anonymization layer for sending pentest data to LLMs — built to be more reliable than match/replace.

Anonproxy sits between your tools (Claude Code, the OpenAI SDK, Burp Suite) and the LLM API. It strips IPs, hostnames, credentials, hashes, tokens, org names and PII out of everything before it leaves the machine, and restores the real values in the reply. The model reasons over realistic surrogates; you read real data.
