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

With no annotations, the description must carry the full burden of behavioral disclosure. It implies a read-only informational tool but does not explicitly state that it performs no mutations, requires no auth, or has any other behavioral caveats. The phrasing 'answers whether this server is earning its place' is not operationally informative.

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 brief and front-loaded with the core subject, but the final clause 'Answers whether this server is earning its place' adds little operational value and is somewhat metaphorical. Still, it is concise overall with minimal waste.

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?

For a zero-parameter statistics tool, the description gives a reasonable sense of the returned dimensions: jobs by kind, check pass rate, and speed. However, it does not clarify the output format or precisely what 'speed' refers to, and it lacks any comparison to sibling tools, leaving some ambiguity for an agent.

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 accepts zero parameters, so the schema already fully covers the input surface. The description does not need to explain parameter details, and the baseline for zero-parameter tools applies.

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 communicates that this tool reports statistics about job delegation, including breakdowns by kind, check pass rates, and speed. It is clear enough to identify the tool's purpose, though it lacks an explicit verb like 'returns' or 'computes' and does not explicitly differentiate itself from siblings.

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 guidance on when to use this tool versus alternatives such as simple_job or summarize. No context, conditions, or exclusions are provided that would help an agent choose this tool correctly.

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