Show HN: We post-trained a model that pen tests instead of refusing your code (argusred.com) AI

Show HN post describes the CosineAI/ArgusRed “cos” CLI, which can run a read-only security scan of a codebase and a separate, permissioned “pen test” mode that attempts exploits against explicitly authorized targets, outputting markdown reports. The author says scans are $20/month subscription-gated, use a harness to block code modification in scan mode and restrict network egress during pen testing, and provides examples of findings such as JWT signature bypass and SSRF via OAuth consent flows.
