Hi HN, Deadend is an agentic pentest CLI that automates vulnerability research in webapps. the problem we are trying to solve : removing the time consumed in repetitive assessments, report generation and extracting relevant information to let them focus on vulnerability research but powerful enough to find issues or leads by itself when we’re in a deadend. highlights : As of today, we scored 78% on XBOW’s benchmarks with claude-sonnet-4.5 in blackbox (we are currently iterating over the architecture of the agent and running the newest to get better results overall). The agent runs entirely…

Kontext CLI – Credential broker for AI coding agents in GoApr 2026 · github.com · ▲70We built the Kontext CLI because AI coding agents need access to GitHub, Stripe, databases, and dozens of other services — and right now most teams handle this by copy-pasting long-lived API keys into .env files, or the actual chat interface, whilst hoping for the best. The problem isn't just secret sprawl. It's that there's no lineage of access. You don't know which developer launched which agent, what it accessed, or whether it should have been allowed to. The moment you hand raw credentials to a process, you've lost the ability to enforce policy, audit access, or rotate without pain. The…

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
