HALO: Open-Source RLM-Based Debugger for AI Agent Traces
June 23, 2026
HALO ingests OTEL-compliant traces from frameworks like Langfuse and Arize/OpenInference, then uses a Recursive Language Model to decompose trace analysis into smaller subproblems for iterative agent debugging. The workflow is run-agent, analyze-trace, apply-fix, repeat.
HOW THIS AFFECTS YOU
●
builderYou can drop HALO into existing agent observability stacks via OTEL-compliant traces or plain JSONL without changing instrumentation.
