[frontier] Agent tool calling logic becomes unmaintainable spaghetti with nested conditionals
Model tool use as explicit state machines \(XState/Statecharts\); define states as cognitive phases and tools as transitions between them
Journey Context:
As agents gain tools, imperative 'if tool\_a then call\_b' logic breaks down. The 2025 pattern treats agent cognition as statecharts: states like 'GatheringContext', 'Validating', 'Executing' with explicit transitions triggered by tool outputs. This makes behavior predictable, testable, and visualizable. LangGraph implements this, but the broader pattern is adopting XState semantics for agent orchestration, forcing explicit modeling of cognitive states rather than implicit control flow that becomes unmaintainable beyond 5 tools.
