test_connection

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

No annotations are provided, so the description carries the full burden. It only states the tool tests the connection and returns info, but does not disclose whether this is a read-only operation, if it requires special permissions, what network calls occur, or what specific connection info is returned. This lack of detail leaves the agent guessing about side effects and output contents.

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 sentence, front-loaded with the verb and resource. Every word contributes to communicating the purpose, with no wasted text.

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?

For a simple tool with no parameters and no output schema, the description is minimally sufficient, but it leaves the 'connection info' unspecified. Without annotations or an output schema, a more detailed description of what info is returned (e.g., version, user, warehouse) would help the agent understand the tool's usefulness and result handling.

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 has zero parameters, so the schema is trivially simple. The description need not add parameter details. With no params, the baseline is 4 and the description adequately aligns with the empty schema.

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 the tool tests the connection to Snowflake and returns connection info. This distinguishes it from siblings like list_tables, execute_query, and describe_table, which all target specific data operations rather than connectivity.

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?

No explicit usage guidance is given, but the purpose is clear: it is for verifying Snowflake connectivity. Since siblings are all data operations, the context implies this is a preflight check, but the description does not state when to prefer this over tools like execute_query or explain_query.

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