traceroute

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

The description mentions it can take several seconds, providing a basic behavioral warning. However, with no annotations, it does not disclose whether it modifies state, requires special permissions, or what happens on failure/timeout.

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?

Extremely concise: one line for purpose and time cost, then two lines for parameters. No wasted words, well-structured for quick reading.

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?

Adequate for a simple tool with two parameters, but missing output description (no output schema). The description does not indicate what the tool returns or how to interpret results, which is important for a diagnostic 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?

Schema coverage is 0%, so the description compensates well by explaining both parameters: address (host/IP with example) and count (number of probes with default). This adds meaning beyond the schema's type and title.

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?

Description clearly states the tool performs traceroute from router to address, mentioning hop trace and time cost. It uses the verb 'traceroute' and provides an example. However, it does not explicitly differentiate from sibling tools like ping, leaving some 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?

No guidance on when to use traceroute versus alternatives such as ping or other network diagnostic tools. The description does not mention prerequisites, contexts, or when not to use it.

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