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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing: not whether this is a read-only inspection or a counter-resetting operation, not what requires permission, and not what the response contains. Two words cannot cover a diagnostic tool's behavior.

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?

Two words are not concise, they are under-specified; nothing is front-loaded because nothing is stated. A single sentence naming the metric domain and read-only nature would cost almost nothing and remove the ambiguity.

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?

With no annotations, no output schema, and a bare tautological description, an agent has no basis for deciding when to call this tool or how to interpret the result. It is completely inadequate even for a zero-parameter 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 nothing for the description to disambiguate; the schema is trivially complete at 100% coverage. Baseline 4 applies, with no param-related gap to compensate for.

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 merely restates the tool name with no verb or scope: it never says what statistics (counters, timings, network, memory?) are collected, over what period, or from which browser/session. Against siblings like health_check, status, and console_logs it is impossible to tell which diagnostic tool this is.

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 when-to-use guidance, no condition that distinguishes it from health_check or status, and no statement about prerequisites. The agent is left to guess the intended call context entirely.

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