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

Annotations already declare destructiveHint=true and idempotentHint=true, so the safety profile is covered. The description adds useful behavioral detail beyond the annotations: deletion is permanent and cascades to subtasks. It does not explain permissions, recovery, or response behavior, but it adds meaningful context for a destructive operation.

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 core sentence is appropriately short and front-loaded. However, the trailing "Free." is ambiguous and does not clearly help an agent decide or invoke the tool, so not 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 simple one-parameter delete tool with strong annotations and full schema coverage, the description is nearly complete: it discloses permanence and subtask cascade. The missing pieces, such as permissions and error behavior, are minor given the structured data already available.

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 single task parameter has 100% schema description coverage, including the expected format such as "WEB-12" or task_id. The description does not add any parameter-level meaning beyond the schema, so the baseline of 3 is appropriate.

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 gives a specific verb and resource: deleting a task, with the added scope that subtasks are included and deletion is permanent. It is clearly distinguishable from tasks_get, tasks_list, and tasks_update by its delete semantics, though it does not explicitly name sibling alternatives.

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 does not state when to use this tool versus alternatives, nor does it describe prerequisites or exclusions. The destructive intent is inferable, but there is no explicit usage guidance beyond the tool name and annotations.

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