    We now write most of our code with agents. For a while, PRs piled up, causing review fatigue, and we had this sinking feeling that standards were slipping. Consistency is tough at this volume. I’m sharing the solution we found, which has become our main product. Continue (https://docs.continue.dev) runs AI checks on every PR. Each check is a source-controlled markdown file in `.continue/checks/` that shows up as a GitHub status check. They run as full agents, not just reading the diff, but able to read/write files, run bash commands, and use a browser. If it finds…

    GitHub: https://github.com/ClioAI/kw-sdk Most AI agent frameworks target code. Write code, run tests, fix errors, repeat. That works because code has a natural verification signal. It works or it doesn't. This SDK treats knowledge work like an engineering problem: Task → Brief → Rubric (hidden from executor) → Work → Verify → Fail? → Retry → Pass → Submit The orchestrator coordinates subagents, web search, code execution, and file I/O. then checks its own work against criteria it can't game (the rubric is generated in a separate call and the executor never sees it…

    Hey HN! I got the idea for this during the Lovable AI competition and decided to turn it into a Chrome extension. TrueSift helps verify the accuracy of online content in real time. What it does: - Uses AI to analyze text on any page and highlight questionable claims. - Provides quick fact-check summaries and trusted sources without leaving the page. - Lightweight and privacy-conscious (no unnecessary data collection). Why I built it: Misinformation spreads fast, and I wanted a tool that makes truth-checking effortless for readers, journalists, and researchers. Try it out: truesift.dev I’d…
