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

With no annotations, the description carries the transparency burden, and it does add meaningful behavior: sorting, filtering, and search execute in SQL so a long list costs one page; and sort_col uses a fixed map, falling back to due date when unrecognized instead of erroring. It does not discuss auth/rate limits, but the disclosed behaviors go well beyond a generic read.

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?

Three front-loaded sentences convey purpose, performance characteristics, and a non-obvious edge case without redundancy. Each sentence earns its place; it is compact but not underspecified.

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?

Combined with a highly descriptive schema and an output schema, the description gives an agent enough to invoke the tool correctly for paginated region-task listing. The main missing elements are usage comparisons and explicit auth/permission context, already penalized in other dimensions.

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 high (90%), so the baseline is 3.access The description adds real value for sort_col by explaining the fixed-map behavior and silent fallback to due date, which the schema does not convey. It also frames search/timeframe as server-side SQL filters, enriching the parameter understanding.

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 opening sentence makes clear that the tool returns a page of a region's tasks, ordered and filtered by the database. It is distinguishable from task_save/task_delete/task_set_done by its list natureto, but it uses a noun phrase rather than an explicit verb like 'lists', so it falls just short of a 5.

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 explicit guidance on when to use this tool versus alternatives such as task_save, task_delete, or the other list tools. The SQL/pagination note implies usefulness for server-side pagination, but no when/when-not boundaries or alternative names are provided.

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