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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is known. The phrase 'for good' usefully reinforces permanence/irreversibility, but the description says nothing about side effects such as whether subtasks are removed, or permission requirements. With annotations carrying the bulk, this is adequate but thin.

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?

Two short sentences with no filler, and the destructive/permanent nature is front-loaded. Every sentence 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 single-parameter destructive tool with annotations covering safety and no output schema, the description supplies the two things an agent most needs: permanence and the user-consent precondition. The remaining gap — cascade behavior toward subtasks — is a minor omission.

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?

There is one required parameter (task_id) with 0% schema description coverage, so the description must compensate and does not — it never mentions the identifier or its format. The parameter is fairly self-evident from its name, but the description adds no meaning at all.

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 states a specific verb+resource ('Delete a task') that is unambiguous against siblings like add_task, update_task, and get_tasks. It does not explicitly name or differentiate itself from an alternative, but the operation is clear.

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?

It gives an explicit precondition: 'Only when the user clearly asks to delete it.' That is real when-to-use guidance beyond the name. It stops short of naming alternatives (e.g., no soft-delete or archive option is mentioned), so it is not a full 5.

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