box_metadata_delete_instance_on_file_tool

Delete a metadata template instance from a specific Box file using its file ID and template key. Removes the associated metadata record from that file.

Instructions

Delete the metadata template instance associated with a specific file.

Args: ctx (Context): The context object containing the request and lifespan context. file_id (str): The ID of the file to delete the metadata from. template_key (str): The key of the metadata template.

Returns: dict: The response from the Box API after deleting the metadata.

Behavior2/5

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

With no annotations provided, the description carries full burden for behavioral disclosure. While 'Delete' implies a destructive operation, it doesn't specify whether this requires special permissions, if the deletion is permanent/reversible, rate limits, or error conditions. The description mentions returning 'The response from the Box API' but gives no indication of what that response contains or means.

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

Conciseness4/5

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

The description is well-structured with clear sections (purpose, Args, Returns) and uses minimal sentences. The purpose statement is front-loaded and direct. However, the Args section could be more integrated into the flow rather than appearing as a separate documentation block.

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

Completeness2/5

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

For a destructive operation with no annotations, 0% schema coverage, and no output schema, the description is insufficient. It doesn't explain what 'deleting the metadata' entails operationally, what permissions are required, potential side effects, or what the API response structure looks like. The agent lacks critical context to use this tool safely and effectively.

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

Parameters3/5

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

Schema description coverage is 0%, so the schema provides no parameter documentation. The description adds basic semantics for both parameters ('file_id' and 'template_key') in the Args section, explaining what they represent. However, it doesn't provide format details, constraints, or examples that would help the agent use them correctly.

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

Purpose4/5

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

The description clearly states the action ('Delete') and target ('metadata template instance associated with a specific file'), providing a specific verb+resource combination. However, it doesn't differentiate from sibling tools like 'box_metadata_update_instance_on_file_tool' or 'box_metadata_get_instance_on_file_tool' beyond the basic action difference.

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

Usage Guidelines2/5

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

The description provides no guidance on when to use this tool versus alternatives, prerequisites, or context. There's no mention of when deletion is appropriate versus updating metadata, or what happens to the file after metadata removal. The agent must infer usage from the tool name alone.

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