test_connection

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

No annotations are provided, so the description carries full burden. It mentions sending PING (read-only behavior) but does not disclose error handling, side effects, or whether an existing connection is required. It lacks transparency beyond the basic operation.

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 unnecessary words. While it lacks structure for parameter details, it efficiently conveys the core action.

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?

Given 6 undocumented parameters, no output schema, and no annotations, the description is severely incomplete. The agent cannot determine what to provide as input, what the output looks like (e.g., success/fail response), or how this tool fits with connection life-cycle siblings.

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?

Schema coverage is 0% and the description fails to explain any of the 6 parameters (host, port, password, etc.). The agent has no guidance on how to construct the connection details from the parameters, making it unclear what values are expected.

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's purpose: test a Redis connection by sending PING. It uses specific verb+resource and distinguishes from siblings like use_connection or get_connection_info.

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 implies usage context (testing a connection) but provides no explicit guidance on when to use it vs. alternatives like use_connection or get_connection_info, nor any prerequisites or when-not-to-use scenarios.

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