delete_table

Drop a table in a Fabric Data Warehouse. Permanently deletes the table and all its data; specify workspace, warehouse, and qualified table name.

Instructions

Drop a SQL table.

Only supported on Fabric Data Warehouses (not SQL Analytics Endpoints). The service rejects SQL Analytics Endpoints with a ToolError.

CAUTION: This is a destructive, irreversible operation. The table and all its data will be permanently deleted. Confirm with the user before calling.

Args: workspace: Workspace name or GUID. item: Warehouse name or GUID. SQL Analytics Endpoints are rejected. qualified_name: Dot-separated qualified table name, e.g. dbo.sales.

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided, so description carries full burden. Clearly states destructive, irreversible operation and that service rejects SQL Analytics Endpoints. Lacks details on permissions or failure conditions, but core behavior is transparent.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Concise, front-loaded with purpose. Three short sentences plus Args list. No redundancy, every sentence adds value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Completes all essential aspects: purpose, constraints, parameter details, caution. Output schema exists, so return values are handled. Agent can correctly select and invoke.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

With 0% schema description coverage, description fully compensates by explaining each parameter: workspace, item (warehouse, not SQL Analytics Endpoints), and qualified_name (dot-separated table name). Adds meaning beyond property names.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Starts with 'Drop a SQL table.', a clear verb+resource. Specifies it is only supported on Fabric Data Warehouses, distinguishing from siblings like 'clear_table' (empties table) and other operations.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly states when to use (drop table) and when not (SQL Analytics Endpoints). Includes caution to confirm with user before calling, providing clear guidance on safe usage.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
