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

With no annotations, the description carries the full burden of behavioral disclosure. It adds useful context that the stats are 'live' and sourced from the 'real platform ledger', implying genuine current data rather than simulated values. However, it does not disclose whether the operation is strictly read-only, what metrics are included, or whether any caching or rate-limiting applies.

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 a single compact phrase that front-loads the core subject ('Live network statistics'). The parenthetical adds source credibility without unnecessary expansion, though the word 'honest' is slightly informal and could be considered nonessential.

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 simple parameterless stats tool, this description gives the agent a general idea of what to expect, but it leaves the exact scope of 'network statistics' undefined (e.g., which metrics, time range, format). Since there is no output schema, the description would benefit from a bit more specificity about the returned data.

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 has zero parameters and an empty input schema, so there is nothing for the description to explain. According to the rubric, a 0-parameter tool earns a baseline of 4, and the description adds no irrelevant parameter information.

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 identifies the resource ('network statistics') and the nature of the data ('live', 'honest aggregates from the real platform ledger'), which makes the tool's purpose understandable. However, it relies on the tool name for the verb and does not explicitly say 'retrieves' or 'returns'. It is distinguishable from sibling tools like get_pricing and list_profiles by the subject matter, though no explicit distinction is made.

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 or when to prefer an alternative. There is no mention of exclusions, prerequisites, or comparison with sibling tools, leaving the agent to infer usage from the name alone.

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