nukon-pi-detect

What it does

Most teams shipping LLM features have no automated check for prompt-injection attacks in CI. nukon-pi-detect fixes that. 48 curated patterns across 5 attack categories: classic injection, jailbreaks, delimiter escapes, Unicode smuggling, and indirect injection. Deterministic regex + Unicode codepoint checks. No ML, no network, no API keys. Zero runtime dependencies. Sub-millisecond scans. Exit code 2 on MALICIOUS - fails CI builds by default. HTML report output, JSON for pipelines. Apache 2.0.

  A minimal TS library that generates prompt injection attacks2025 · prompt-injector.blueprintlab.io · ▲33

  I made an open source, MIT license Typescript library based on some of the latest research that generates prompt injection attacks. It is a super minimal&#x2F;lightweight and designed to be super easy to use. Keen to hear your thoughts and please be responsible and only pen test systems where you have permission to pen test!

  A local-first, reversible PII scrubber for AI workflowsDec 2025 · medium.com · ▲38

  Hi HN, I’m one of the maintainers of Bridge Anonymization. We built this because the existing solutions for translating sensitive user content are insufficient for many of our privacy-concious clients (Governments, Banks, Healthcare, etc.). We couldn't send PII to third-party APIs, but standard redaction destroyed the translation quality. If you scrub "John" to "[PERSON]", the translation engine loses gender context (often defaulting to masculine), which breaks grammatical agreement in languages like French or German. So we built a reversible, local-first pipeline for Node.js&#x2F;Bun. Here…

  I built a tiny LLM to demystify how language models work▲915

  Built a ~9M param LLM from scratch to understand how they actually work. Vanilla transformer, 60K synthetic conversations, ~130 lines of PyTorch. Trains in 5 min on a free Colab T4. The fish thinks the meaning of life is food. Fork it and swap the personality for your own character.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https:&#x2F;&#x2F;text.blogosphere.app&#x2F; Non-minimal: https:&#x2F;&#x2F;blogosphere.app&#x2F; If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
