tb_create_board · Forgespec MCP: Risk & Policy

WHAT IT DOES

What tb_create_board does on Forgespec

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

WHY IT NEEDS A POLICY

Why tb_create_board needs a policy

Creating a task board is a Write operation—it creates new data structures and metadata reversibly (boards and tasks can be deleted or modified later). The severity is medium because misuse could create spurious boards/tasks cluttering the project workspace, but the impact is reversible and scoped to a single project's task management system, not destructive data loss or system-wide effects.

From the tool's definition Tool name 'tb_create_board' and description state it 'Create a new task board' which is a create/add operation. The optional inline task creation feature indicates it modifies data by adding tasks in 'a single atomic call'.
