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

No annotations are provided, so the description carries the burden. It conveys that this is a read operation ('Fetch') and adds useful return-content context ('with all its submissions'). It does not disclose error behavior, authentication requirements, or response format, but for a simple fetch this is acceptable.

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 front-loads the core action and object, then adds the important detail about submissions, making it easy for an agent 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 single-parameter fetch tool, the description is reasonably complete: it names the resource, the lookup key, and the expected included data. It lacks explicit error/not-found handling, but given the low complexity and absence of an output schema, this is a minor 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 input schema only defines id as an integer with a minimum of 1, with no description coverage. The description's 'by id' clarifies that the parameter is the task identifier, adding some meaning beyond the raw schema. However, it does not provide additional context such as where to obtain the id or edge cases.

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 clear verb ('Fetch'), a precise resource ('a single task by id'), and a key detail ('with all its submissions'). It distinguishes itself from siblings like list_tasks (which lists multiple tasks) and create_task (which creates).

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 intended use is implied by 'Fetch a single task by id' — use it when you need one specific task rather than a list. However, it does not explicitly state when not to use it or mention alternatives such as list_tasks for broader queries.

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