agent-debugging

unbox-ai is an open-source CLI and local viewer for inspecting AI agent traces. It visualizes token usage, latency, tool calls, and repeated context in a bundle-analyzer-style interface, and also includes read-only commands for agents and a live AI SDK DevTools mode.

HALO is an open-source local debugger and optimizer for AI agent traces. It collects execution traces, analyzes recurring failure modes with an RLM-based engine, and feeds findings into a coding agent to improve the harness.

Open-source resilience and debugging proxy for autonomous AI agents. It checkpoints LLM and tool calls, supports cache recovery, human-in-the-loop approval, multi-model fallback, and exports trajectories for fine-tuning.
