Show HN: AURA, an open-source Rust agent for investigating production incidents

jvogt · hn · 2026-09-02

The SRE team at Mezmo open-sourced AURA (Apache 2.0), a Rust-based agent harness for incident response, built after struggling with context overflow, hallucinations, and approval fatigue using Claude and LangChain. Key design: workers scoped to task domains (logs, metrics, git), permissions enforced deterministically outside the agent's context so it can't self-escalate, large tool outputs persisted to disk with slicing tools for context management, and human-in-the-loop for sensitive actions. They report strong root-cause accuracy even on open-weights models. Installable via rpm/deb/brew, runs as a workstation assistant or daemon with any OpenAI-compatible frontend, no signups or open-core trapdoor. Repo: mezmo/aura.
