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

Annotations already declare destructiveHint=true, so the description adds the nuance of 'permanently,' which is a useful behavioral detail beyond the annotation. However, it doesn't disclose any side effects, permissions, or what happens if the alert doesn't exist. The added context is minimal but non-contradictory.

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?

The description is a single, focused sentence with no filler. It is concise and front-loaded with the key action, making it easy to parse quickly.

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 delete operation with one parameter and no output schema, the description covers the core action. However, it omits potential caveats like irreversibility (beyond 'permanently'), cascading effects, or error behavior. Given the tool's simplicity, it is mostly complete but lacks a few details an agent might need.

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 has no description for alert_id, and the tool description doesn't explain its purpose or how to obtain it. While the name 'alert_id' is self-explanatory, the description fails to add any meaning beyond the schema. With 0% schema coverage, the description should compensate but does not.

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?

The description uses the specific verb 'delete' with the resource 'alert' and adds 'permanently' and 'from the database,' clearly distinguishing it from sibling tools like deactivate_alert (state change) and create_alert (creation). The intent is unambiguous.

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 provides no guidance on when to use this tool versus alternatives like deactivate_alert. It doesn't state that deactivation is preferred for temporary disablement or that this is the only way to remove an alert permanently. The agent must infer usage from the name.

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