get_connection_status

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

With no annotations, the description bears full responsibility for behavioral disclosure. It only states 'Check connection status', which implies a read-only operation but doesn't clarify whether it performs network I/O, what side effects it has, or what the output entails. No mention of error behavior or response format.

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 one short sentence, achieving high conciseness. It front-loads the core purpose without redundancy. However, it could incorporate additional behavioral context without losing conciseness, so it's not a perfect 5.

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 tool has zero parameters and no output schema, so the description should compensate by explaining the return value or behavior. It doesn't; it only states the generic purpose, leaving the tool's actual output format and status meanings unspecified.

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 input schema has zero parameters, so schema coverage is 100% by default. The description adds no parameter-specific information, but there are no parameters to document. According to the rubric, a baseline of 4 applies for 0-param tools.

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 uses a clear verb 'check' and specific resource 'connection status', distinguishing it from sibling tools that focus on data queries and summaries. However, it doesn't specify what type of connection (e.g., device, network, API), leaving slight ambiguity.

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 provides no guidance on when to use this tool versus alternatives, no prerequisites, no exclusions, and no context about typical usage. It is a single declarative sentence without directional advice.

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