kusto_show_command

Read-only

Execute read-only .show management commands on a Kusto database to retrieve metadata and configuration, returned as JSON.

Instructions

Executes a Kusto .show management command on the specified database.
If no database is provided, it will use the default database.

Only .show commands are accepted.

:param command: The .show command to execute.
:param cluster_uri: The URI of the Kusto cluster.
:param database: Optional database name. If not provided, uses the default database.
:param client_request_properties: Optional dictionary of additional client request properties.
:return: The result of the command execution as a list of dictionaries (json).

Behavior4/5

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

Annotations already indicate read-only and non-destructive nature. The description adds value by detailing default database behavior and return format (list of dictionaries as JSON), going beyond annotations.

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 efficient, starting with purpose and constraints, then parameter details. Some redundancy exists (default database mentioned twice), but overall it's well-organized and not overly verbose.

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

Completeness4/5

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

The description covers the tool's core functionality, constraints, and parameters adequately. For a simple read-only tool with an output schema, missing elements like error handling or sibling differentiation are minor gaps.

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, the description fully compensates by explaining each parameter: command, cluster_uri, database (including default behavior), and client_request_properties. This adds essential meaning beyond the schema.

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?

The description clearly states 'Executes a Kusto .show management command' with a specific verb and resource. It further distinguishes by limiting to .show commands, which differentiates it from sibling tools like kusto_command or kusto_query.

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

Usage Guidelines4/5

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

The description explicitly says 'Only .show commands are accepted,' providing a clear constraint. However, it does not mention alternatives like kusto_command for other commands, so it lacks explicit when-not-to-use guidance.

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