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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so safety is covered. The description adds domain context (what alert rules are) but says nothing about pagination behavior, default ordering, or what an empty result means — gaps that matter for a paginated list tool.

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 zero filler. It is efficient, though the brevity contributes to the missing operational detail elsewhere.

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?

Five optional parameters, no output schema, and no annotations explaining return shape. The description should at least sketch the returned list shape or pagination model; as written, an agent knows what the tool returns conceptually but not how to page or interpret results.

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 only 40%: 'page', 'enabled' and 'severity' are undocumented in the schema, and the description mentions none of the five parameters. The description does not compensate for the low coverage, leaving the filter semantics (e.g. whether severity/enabled combine as AND) unclear.

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 the verb 'List' and the resource 'alert rules', and adds a useful semantic gloss distinguishing alert rules as 'extra response-time and uptime conditions on top of the built-in alerts'. It does not explicitly distinguish itself from the nearby vs_alerts_list (which lists fired alerts, not rule definitions), so an agent must infer that boundary.

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 versus vs_alerts_list, vs_alert_rules_get, or the other alert-rule siblings. Usage is only implied by the presence of filter parameters in the schema.

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