Project mention: Show HN: Ask your LLM traces what went wrong (vLLora) | news.ycombinator.com | 2026-01-26
Hi HN,
We built Lucy, a trace-debugging tool inside vLLora (our open-source LLM observability stack).
The problem: Debugging AI agents is painful. A single failure often hides inside a trace with 200+ spans—tool calls, retries, partial outputs, and silent failures. Even with tracing, finding the actual root cause (e.g. a tool schema mismatch or a contradictory system prompt) usually means manually scanning logs for 20+ minutes.
What Lucy does: Lucy lets you query your traces using natural language. You can ask things like “Why did this agent loop?” or “Which step was slow?” and it inspects the span tree to surface likely causes. For example, it can flag:
- Tool schema mismatches (e.g. hallucinated or invalid arguments)
- Prompt contradictions (e.g. system instruction conflicts with user intent)
- Silent failures (e.g. context truncation or max-token exits)
It’s early and still in beta.
We’d love to hear how you’re debugging agent failures today—logs, replay, evals, custom scripts, or something else.

baibot
🤖 A Matrix bot for using different capabilities (text-generation, text-to-speech, speech-to-text, image-generation, etc.) of AI / Large Language Models (OpenAI, Anthropic, etc.)
Project mention: Komai: a fine Matrix chat app you can get to love | news.ycombinator.com | 2026-05-07Your Rust-based AI chatbot (https://github.com/arcuru/chaz) was an inspiration!
It made me think: we don't have to suffer the brokenness of the old bot (https://github.com/matrixgpt/matrix-chatgpt-bot) anymore. Still, I wanted something more thread-based and more powerful than what you had built.. and I wanted a playground to learn some Rust.
To clarify for anyone that might get confused: baibot (https://github.com/etkecc/baibot) is not based on any of the chaz code, nor on the matrix-chatgpt-bot code. It's completely manually-built / independently-built (in Rust), by me, over multiple months of unpaid FOSS work.
