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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so safety is covered. The description adds the paged/GET /tasks context, but says nothing about result ordering, total counts, or the volume of data to expect from an open-world list call.

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 front-loaded sentence with the field list and pagination note packed in tightly; nothing is wasted. The parenthetical enumeration is dense but earns its place given there is no output schema.

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?

With no output schema, the field enumeration is the only place the agent learns what a task record contains, and pagination is addressed. For a zero-required-parameter list tool this is close to sufficient; only ordering and scope hints are missing.

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 100%, with both page and per_page fully documented including defaults, bounds, and the next_page chaining hint. The description only restates 'paged', so it adds no semantics beyond the schema – baseline 3 applies.

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 and resource ('List tasks') and enumerates the fields each task carries, so the agent knows both the operation and the payload shape. It doesn't explicitly name the sibling alternatives (cats_get_task for one task, cats_list_candidate_tasks for a candidate's tasks), but the list-vs-get distinction is unambiguous from the name.

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?

'paged' plus the schema's 'Pass the previous reply's next_page' implies the iterate-until-exhausted workflow. However, the description never says when to prefer this over cats_list_candidate_tasks or cats_filter_candidates, and gives no exclusion or scoping guidance.

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