Traceroute Result

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

The readOnlyHint=true annotation already tells the agent this is a safe read. The description adds nothing beyond that — it doesn't say whether a traceroute must be running, whether the read blocks or returns partial output, or how long results persist.

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?

A single front-loaded phrase with no filler, which is appropriate for a zero-argument read. It is concise but so minimal that concision shades into under-specification rather than efficient communication.

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?

An output schema exists, so return values need not be described, and there are no parameters to document. What is missing is the operational context: how this relates to the 'traceroute' and 'stop_traceroute' lifecycle, which is the only real ambiguity left for this simple tool.

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 takes zero parameters, so there is no parameter semantics for the description to compensate for. The baseline for a parameterless tool applies, and the schema (with additionalProperties: false) is fully self-describing.

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 gives a specific verb+resource ('read traceroute result'), so the agent knows this retrieves prior traceroute output. However, it draws no explicit line against the closely related siblings 'traceroute' (which presumably starts the run) and 'ping_result', leaving the agent to infer the relationship.

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?

There is no statement of when to call this tool versus 'traceroute' or 'stop_traceroute'. The intended sequence (start traceroute, then poll this result) is only implied by the name pairing and is never spelled out.

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