WHAT IT DOES

What apply_strategy does on Agent-Comm-Hub

AI agents use apply_strategy to create or update resources in Agent-Comm-Hub — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Agent-Comm-Hub environment.

WHY IT NEEDS A POLICY

Why apply_strategy needs a policy

The tool modifies state by recording strategy applications and incrementing a counter. This is a Write operation (reversible data modification) rather than Read (no side effects), Execute (no external code/command execution based on description), Destructive (no irreversible deletion), or Financial (no money movement). The context of 'approved strategy' with audit logging suggests controlled, documented changes.

From the tool's definition Tool name 'apply_strategy' and description '采纳一个已审批的策略。记录到策略应用记录中，apply_count 自增' (Adopt an approved strategy.
