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

Annotations already declare the safety profile (readOnlyHint=false, destructiveHint=false, idempotentHint=true, openWorldHint=true). The description contributes the ownership/authorization scoping ('owned by the connected account') and the required prior state ('stopped'). It adds modest value beyond structured fields but says nothing about failure modes if the alert is already active or lacks ownership.

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 short sentence with zero redundancy, front-loading the action and resource. Every clause 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 simple state-toggle tool, the description plus an output schema and full annotation set cover almost everything the agent needs. The remaining gap is the unexplained 'id' parameter, but returns and safety behavior are already handled by structured fields.

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 single parameter 'id' is undocumented — the description never says what the id identifies or where to obtain it. The schema supplies only type/pattern/maxLength constraints, so the description fails to 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 specific verb+resource ('Reactivate a stopped alert') plus a scoping constraint ('owned by the connected account'), so the agent knows exactly what state change occurs. It does not explicitly name stop_alert as the inverse operation, but the pairing is evident from the sibling list.

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 word 'stopped' implies the precondition for calling this tool (the alert must already be stopped), which is useful implicit guidance. However, there is no explicit when-to-use/when-not statement and no named alternative such as stop_alert for the reverse case.

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