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

With no annotations, the description carries the burden of behavioral disclosure. 'Fetch' clearly signals a read-only operation with no mutation, but nothing is said about missing ids, return shape, or failure behavior. This is adequate for a simple getter but has clear gaps.

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?

A single sentence that is front-loaded with the verb and object, with no filler or repetition. Every word contributes to the meaning.

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 get-by-id tool, the description is largely complete: it names the resource, the lookup key, and the singular return intent. The absence of an output schema and any mention of return format is a minor gap, but the tool is simple enough that the missing information is easily inferable.

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 0% description coverage, so the description must compensate. It does confirm that 'id' is the identifier of the task/event/meeting being fetched, but adds no format, source, or usage details beyond what the parameter name already suggests. Minimal but real added meaning.

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 a specific verb ('Fetch') and resource ('single task/event/meeting by id'), making the tool's core operation clear. The 'single ... by id' scope distinguishes it from sibling tasks_list and other task mutators without needing to open the schema.

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 implies the appropriate use case: when you have an id and need exactly one task/event/meeting. However, it does not explicitly mention alternatives or state when to prefer tasks_list, tasks_get, or another sibling, so the guidance is more implied than explicit.

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