Viewing enriched Twitter post
Built a lightweight trace viewer to speed up LLM evals—heavily inspired by lessons from @sh_reya and @HamelHusain's evals course. Kept it simple: FastAPI + vanilla HTML/JS. Features: failure banner, execution-flow timeline (LLM ↔ tools), keyboard shortcuts, and an annotation panel (pass/fail/defer + tags). We’re already using it internally to review a small agentic loop over GitHub activity. 🎥 2-min demo video link in the thread below #LLMOps #Evals #Agents #FastAPI
