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

Annotations are empty, so the description carries the disclosure burden. It reveals the operation is a configuration change and states auth/eligibility requirements, which is useful. However, it does not mention side effects on existing alert settings, whether values are overwritten, or confirmation/response 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?

A single sentence delivers the action, the resource, the allowed values, and the access prerequisites. Nothing is wasted or repeated, and the core behavior is front-loaded.

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 two-parameter mutation tool, the prerequisites and threshold values are covered. However, without annotations or an output schema, the description omits what the caller should expect after invocation and any side effects, leaving a minor gap.

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 100%, so the schema fully documents monitor_id and alert_threshold, including allowed values. The description only restates the allowed threshold values without adding new meaning, meeting the baseline but no more.

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 specific verb ('Configure') and a precise resource: the consecutive-failure count that triggers alerting, listing the allowed values. This clearly differentiates it from sibling tools like update-monitor or diagnose-incident.

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 implies the use case — changing the failure threshold necessary before an alert fires. It discloses access prerequisites (Full Access token, eligible paid plan), but does not explicitly say when this tool should be chosen over alternatives like update-monitor, nor when it should not be used.

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