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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=false, so the safety profile is covered. The description adds useful scoping context ('latest', 'completed' only), but says nothing about what happens when no completed task exists or how 'latest' is ordered.

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 six-word front-loaded phrase with no padding and the key qualifier ('latest completed') placed early. Brevity here borders on under-specification rather than waste.

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?

An output schema exists, so return values need not be described, and annotations cover the safety profile. However, the tool's only input is entirely undefined for the agent, leaving a real gap for a task-lookup tool with many related siblings.

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 required parameter, task_type, has 0% schema description coverage and no enum or example values, and the description never mentions it. With zero coverage in structured fields, the description needed to define what task types are accepted and it does not.

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?

States a specific verb ('Read') and a specific resource scope ('latest completed task summary'), so the agent knows it retrieves the most recent finished task rather than a list. It does not distinguish itself from close siblings such as tasks_list, tasks_get_status, or tasks_get_create_detail.

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?

There is no guidance on when to prefer this over tasks_list or tasks_get_status, and no mention of preconditions such as a task having completed. The agent must infer usage from the name alone.

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