Compiled Skills Cut Agent Tokens by as Much as 88.9%
HEXIS turned reusable procedures into extended state machines with static checks and replay.
Summary
HEXIS turned reusable procedures into extended state machines with static checks and replay.
HEXIS compiles agent skills into extended finite-state machines whose transitions, guards and tool calls can be inspected before execution. Across four benchmarks and four executors, the authors report a 16.1-point gain over Skill+ReAct. For Qwen3.8-27B, token use fell between 38.4% and 88.9%, while accepted traces could be replayed; the results depend on the tasks and skill library tested.
