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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is fully covered. The description adds that results bundle recent delivery attempts, which is genuine context beyond the annotations, but it doesn't say whether all alerts are returned, how they are ordered, or whether results are truncated.

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 that front-loads the action and appends the one useful detail about return content. Nothing is redundant or padded.

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 parameterless read tool, the essentials are present, but with no output schema and no pagination or volume hints, an agent can't predict how large the response is or whether it covers all alerts. One clause on scope (e.g., "returns all alerts for your account") would close the 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?

The tool takes zero parameters, so there is no parameter meaning for the description to supply; baseline 4 applies. The schema is empty and correctly so.

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 and resource ("List your alerts") and adds that results include "recent attempts and deliveries," which tells the agent what content comes back. It is clearly separable from the mutation siblings (create_alert, delete_alert, activate_alert, deactivate_alert) by name, though it doesn't explicitly contrast with listing siblings like list_changes or list_wire.

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 explicit when-to-use or when-not-to-use guidance and no named alternative. However, with zero parameters and an unambiguous name, the usage is strongly implied: this is the unfiltered read-only listing of alerts, as opposed to the create/delete/activate siblings.

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