Evoflux: Inference-Time Evolution of Executable Tool Workflows for Compact Agents
Quick Answer
Evoflux enhances the execution feasibility of compact language models in tool workflows from 3% to 17-24% on MCP-Bench tasks, outperforming SFT and ReAct under limited teacher-trace budgets.
Quick Take
This evolutionary search method effectively repairs executable workflows through structured edits and adaptive feedback.
Key Points
- Evoflux improves execution feasibility for small planners on -Bench tasks.
- Execution feasibility rose from 3% to 17-24% using Evoflux.
- SFT and SFT+ underperform compared to Evoflux on the same data.
- ReAct achieves higher peaks but with increased variance and costs.
- Evoflux utilizes evolutionary search to repair executable tool workflows.

arXiv:2606. 12674v1 Announce Type: new Abstract: Compact language models (LMs) reduce cost, latency, and deployment risk for tool agents. Yet -style requires more than isolated : an agent must discover tools from live catalogs, satisfy schemas, preserve dependencies across intermediate outputs, and ground final responses in executed evidence. Small planners often generate plausible workflow graphs that fail under tool resolution, parameter validation, dependency tracking, or execution.
We argue that this failure mode is poorly handled by small-corpus distillation. …
