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

The annotations already declare destructiveHint=true and readOnlyHint=false, so the agent knows this is a destructive mutation. The description adds no additional behavioral context, such as whether deletion is permanent, whether it cascades to related data, or whether special permissions are required. It does not contradict the annotations, but it also does not go beyond them.

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?

'Delete a task' is concise, front-loaded, and contains no unnecessary words. For a simple deletion operation, this length is appropriate, though it sacrifices informational richness in other dimensions.

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 one-parameter destructive operation, this is minimally viable: the schema covers the parameter and the annotations cover the destructive nature. However, the description does not mention irreversible consequences, side effects, or what happens after deletion, and there is no output schema to clarify the return value.

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 100%, with taskId described as 'Task ID'. The description itself adds no extra meaning beyond the schema, so it sits at the baseline 3 for a fully documented parameter.

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 'Delete a task' clearly states the verb and resource, distinguishing it from sibling tools like trip_task_create, trip_task_update, and trip_task_list. It is unambiguous about the operation's nature, though it does not explicitly mention the trip context carried by the tool name.

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 such as trip_task_update or trip_task_complete. There are no prerequisities, exclusions, or hints about when deletion is the right choice, leaving the agent to rely on the tool name alone.

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