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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the safety profile is covered. The description adds that evidence is 'bounded' and scoped to the 'authenticated monitor account,' which is useful context. It does not describe not-found/error behavior, but that is a minor gap given the annotations.

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 states the resource, return content, and account scope with no filler. Every word earns its place.

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 one-parameter read tool, the description adequately states what is returned ('one structured alert' and 'bounded evidence') and the account scope. The main missing context is the provenance of alertId and the explicit relationship to list_monitor_alerts, but these are not critical for invoking the tool. It is complete enough to call correctly.

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 schema provides only the parameter name and length constraints, with 0% description coverage. The description does not mention alertId, how to obtain it, or whether it is the identifier returned by list_monitor_alerts. Because the description fails to compensate for the schema's lack of parameter description, parameter semantics are weak.

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?

Description uses a specific verb ('Returns') and identifies the resource: one structured alert plus its bounded evidence for the authenticated monitor account. The singular 'one' distinguishes it from list_monitor_alerts, which handles fetching multiple alerts. This lets an agent know exactly what the tool does without opening the schema.

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 singular phrasing implies this tool is for targeted retrieval of a single alert rather than enumeration, which list_monitor_alerts handles. However, there is no explicit statement of when to use this versus list_monitor_alerts or how to obtain a valid alertId. Usage is implied, not spelled out.

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