execute_query

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

The description mentions 'execute verbatim' and 'return all result sets' but does not disclose potential side effects, such as data modification or the need for elevated permissions. With no annotations, this leaves significant behavioral uncertainty.

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

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

The description is a single, concise sentence with no redundant information, effectively communicating the tool's function.

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

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

The description is adequate for a simple tool, but it omits important context such as error handling, transaction behavior, or security considerations. The output schema is present, so output format is not needed, but the description could be more complete regarding execution risks.

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

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

The tool description refers to 'SQL text', which adds some meaning to the 'query' parameter, but the parameter itself is not described in the schema. The description partially clarifies the parameter's purpose.

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

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

The description clearly states that the tool executes SQL text verbatim on SQL Server and returns all result sets, which precisely defines its purpose.

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

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

The description does not explicitly state when to use this tool versus alternatives. Since no sibling tools are present, it is less critical, but the description lacks explicit guidance on appropriate use cases.

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