Show HN: A Prompt-Injection Firewall for AI Agents and RAG Pipelines https://ift.tt/h40kpqW
Show HN: A Prompt-Injection Firewall for AI Agents and RAG Pipelines We built SafeBrowse — an open-source prompt-injection firewall for AI systems. Instead of relying on better prompts, SafeBrowse enforces a hard security boundary between untrusted web content and LLMs. It blocks hidden instructions, policy violations, and poisoned data before the AI ever sees it. Features: • Prompt injection detection (50+ patterns) • Policy engine (login/payment blocking) • Fail-closed by design • Audit logs & request IDs • Python SDK (sync + async) • RA…
Show HN: Client-side encrypted AI detector using model ensembling https://ift.tt/peodc8G
Show HN: Client-side encrypted AI detector using model ensembling Hi HN, I’m Oscar, a Year 8 student from Australia who enjoys messing around with computers and AI. I recently built an AI detector to build on my skills in computer science. I entered the prototype into the Oliphant Science Awards which is a local science competition (writing a 4000-word report on the methodology) and ended up winning, so I decided to polish it into a real web service that the world can make use of. I noticed that schools and businesses are rushing to use AI det…
Show HN: A dynamic key-value IP allowlist for Nginx https://ift.tt/jeFG9mw
Show HN: A dynamic key-value IP allowlist for Nginx I am currently working on a larger project that needs a short-lived HTTP "auth" based on a separate, out-of-band authentication process. Since every allowed IP only needs to be allowed for a few minutes at a time on specific server names, I created this project to solve that. It should work with any Redis-compatible database. For the docker-compose example, I used valkey. This is mostly useful if you have multiple domains that you want to control access to. If you want to allow 1.1.…

Show HN: I created a 2025 Wrapped for WhatsApp Conversations https://ift.tt/PokbVTf
Show HN: I created a 2025 Wrapped for WhatsApp Conversations Hey HN! As I sat to write my 2025 reflection, I realized one thing I was missing was a ‘year wrapped’ for my relationships — I got my music, got my photos, got my fitness wraps — but what about my relationships? Specifically, I wanted to figure out what my text conversations say about my relationships and myself, and if there’s been evolution throughout the year. Who reaches out more? What’s our tone and conflict resolution? What were our month by month successes and conflicts? So I …
Show HN: Stop Claude Code from forgetting everything https://ift.tt/g3GR0Kd
Show HN: Stop Claude Code from forgetting everything I got tired of Claude Code forgetting all my context every time I open a new session: set-up decisions, how I like my margins, decision history. etc. We built a shared memory layer you can drop in as a Claude Code Skill. It’s basically a tiny memory DB with recall that remembers your sessions. Not magic. Not AGI. Just state. Install in Claude Code: /plugin marketplace add https://ift.tt/cIqoeCW /plugin install ensue-memory # restart Claude Code What it does: (1) persists context between sess…
Show HN: Agtrace – top and tail -f for AI coding agent sessions https://ift.tt/XcKeYIC
Show HN: Agtrace – top and tail -f for AI coding agent sessions Hey HN, I built agtrace because I kept losing track of what was happening in my Claude Code sessions – context pressure, tool calls, costs. It's basically `top` for AI coding agents: - Live dashboard showing context window usage and activity - Session history you can query and diff - Works with Claude Code, Codex, and Gemini CLI - 100% local, reads existing logs, no cloud Install: `npm i -g @lanegrid/agtrace` The core idea is pointer-based indexing (no log duplication) and sch…
