List Monitors

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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description's addition of "current state and freshness" hints at a data-staleness trait that annotations do not convey, but it is not elaborated (how fresh, refreshed when, pagination, ordering).

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 sentence with no filler or repetition. It is efficient, though "freshness" is left undefined, which costs it the top score.

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 read-only list tool with full annotation coverage this is minimally viable, but with no output schema the agent gets no sense of what fields (state, freshness, identifiers) come back, and the `debug` flag is unexplained. It is adequate but has clear gaps.

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 description coverage is 0% and the description never mentions the single `debug` parameter, so nothing in the text clarifies its effect on output or behavior. The parameter name is fairly self-evident, which prevents a 1, but the description does not compensate for the coverage gap.

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?

States a clear verb+resource ("List ... Monitor") and adds scope ("current state and freshness"), which an agent can distinguish from get_monitor or preview_monitor by the standard list-vs-get convention. It does not explicitly name siblings or clarify what a "monitor" is in this product, so it falls short of a 5.

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 gives no when-to-use guidance, no conditions selecting it over get_monitor, and no prerequisites. Usage is only inferable from the verb "List" and the sibling naming pattern, which is weaker than explicit guidance.

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