ping_robot

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It explains what the tool does (ping IP, check port) and mentions diagnostic interpretation ('successful ping to the IP but not the port can indicate that ROSbridge is not running'), which adds useful context. However, it doesn't disclose timeout behaviors, error handling, or what constitutes a 'successful' result beyond the example.

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 perfectly sized and front-loaded: the first sentence states the core purpose, the second adds diagnostic context, and the third provides a concrete example. Every sentence earns its place with no wasted words, making it easy for an agent to quickly understand 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?

Given no annotations, no output schema, and 4 parameters (2 undocumented), the description is moderately complete. It covers the core functionality and main parameters well but lacks details on optional parameters, return values, error conditions, and timeout behaviors. For a network diagnostic tool, more behavioral context would be helpful.

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 description coverage is 0%, so the description must compensate. It explicitly names and provides an example for the two required parameters (ip, port), giving them clear meaning. However, it doesn't mention the two optional timeout parameters (ping_timeout, port_timeout) at all, leaving them undocumented. The description adds significant value for the core parameters but misses the optional ones.

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 with specific verbs ('ping', 'check') and resources ('robot's IP address', 'specific port'). It distinguishes this tool from all sibling tools, which focus on ROS services, topics, and publishing rather than network connectivity testing. The example reinforces the specific functionality.

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 clear context for when to use this tool: to test network connectivity to a robot and check port availability, specifically mentioning ROSbridge as a potential use case. However, it doesn't explicitly state when NOT to use it or name specific alternatives among the sibling tools for different network or ROS diagnostic tasks.

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