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

Annotations declare readOnlyHint=true and destructiveHint=false, so safety profile is covered. But the description adds almost nothing beyond that: it does not describe error behavior when no completed task exists, freshness guarantees, or what happens with different task_type values. For a tool whose whole point is retrieving 'latest', the recency semantics are undisclosed.

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 four-word sentence is concise but under-specified rather than efficient. It is front-loaded but contains no actionable detail beyond the name.

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-value explanation is not required, but the input schema discourages reliance on its description field (0% coverage) and the description does not fill the gap. Combined with a crowded sibling set of tasks_* tools, the definition is insufficient for reliable tool selection.

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 0% for the sole required parameter task_type, and the description does not mention it at all. With no enum and no description anywhere, the agent has no way to know valid task_type values from this definition.

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 verb (read) and resource (latest completed task summary), which is clearer than a tautology. However, it does not distinguish itself from siblings like tasks_get_status, tasks_list, or tasks_get_create_detail, leaving ambiguity about what 'latest' means and which task's summary is returned.

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?

No when-to-use guidance, no mention of alternatives, and no conditions under which this should be preferred over tasks_get_status or tasks_list. 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.
