Show HN: Agent Tinman – Autonomous failure discovery for LLM systems https://ift.tt/swIJ8mg

Show HN: Agent Tinman – Autonomous failure discovery for LLM systems Hey HN, I built Tinman because finding LLM failures in production is a pain in the ass. Traditional testing checks what you've already thought of. Tinman tries to find what you haven't. It's an autonomous research agent that: - Generates hypotheses about potential failure modes - Designs and runs experiments to test them - Classifies failures (reasoning errors, tool use, context issues, etc.) - Proposes interventions and validates them via simulation The core loop runs continuously. Each cycle informs the next. Why now: With tools like OpenClaw/ClawdBot giving agents real system access, the failure surface is way bigger than "bad chatbot response." Tinman has a gateway adapter that connects to OpenClaw's WebSocket stream for real-time analysis as requests flow through. Three modes: - LAB: unrestricted research against dev - SHADOW: observe production, flag issues - PRODUCTION: human approval required Tech: - Python, async throughout - Extensible GatewayAdapter ABC for any proxy/gateway - Memory graph for tracking what was known when - Works with OpenAI, Anthropic, Ollama, Groq, OpenRouter, Together pip install AgentTinman tinman init && tinman tui GitHub: https://ift.tt/WDN7tjG Docs: https://oliveskin.github.io/Agent-Tinman/ OpenClaw adapter: https://ift.tt/qQJwSZu Apache 2.0. No telemetry, no paid tier. Feedback and contributions welcome. https://ift.tt/WDN7tjG February 1, 2026 at 12:17AM

Show HN: Agent File (.af) – An open file format for agents https://ift.tt/fzI5HcG

Show HN: Agent File (.af) – An open file format for agents Hi HN - We’re building Agent File (.af), which makes it possible to re-create the exact same agent (including memories, tools, message history, configs, etc.) across different machines. A big difference between LLMs and agents is that agents have associated state: system prompts, editable memory (personality and user information), tool configurations (code and schemas), and LLM/embedding model settings. While you can run the same LLM as someone else by downloading the weights, there’s no “representation” of agents that allows you to re-create an instance of an agent across services. Agent File (.af) is an open standard file format for serializing stateful agents. Originally designed for the Letta framework, .af is a human-readable representation of all the associated state of an agent to reproduce the exact behavior and memories. To demonstrate .af, we also made a few example agents with download links to .af: - MemGPT: An agen...

Show HN: Repomance: A Tinder style app for GitHub repo discovery Hi everyone, Repomance is an app for discovering curated and trending repositories. Swipe to star them directly using your GitHub account. It is currently available on iOS, iPadOS, and macOS. I plan to develop an Android version once the app reaches 100 users. Repomance is open source: https://ift.tt/Mqe9zG0 All feedback is welcome, hope you enjoy using it. https://ift.tt/6LGBVdU January 15, 2026 at 12:24AM
