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

Annotations already declare readOnlyHint=true, so the safety profile is covered. The description adds genuinely new behavioral context beyond the annotations: the underlying HTTP verb/path (GET /api/v0/tasks) and the response envelope '{ meta, response }', which matters because no output schema exists. It omits any note on rate limiting, default ordering, or maximum result windows.

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 short sentences, each earning its place: resource definition first, endpoint second, query/return contract third. No filler, no repetition of the title, and the most important scoping information is front-loaded.

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 five-parameter, zero-required, read-only list tool with no output schema, the description covers purpose, endpoint, supported query modifiers, and the return envelope. It is close to complete; the remaining gap is that it does not characterize what a task object contains or the default sort/pagination behavior an agent would need to interpret results.

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%, so every parameter (including the intricate _filters syntax) is already fully documented in the schema. The description only re-enumerates the same five knobs (_page/_limit/_fields/_filters/_search) without adding syntax, defaults, or interaction rules. Baseline 3 is appropriate when the schema does all the work.

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 (List) plus resource (tasks) and then disambiguates the resource itself as 'units of work logged against an object such as a job or company,' which prevents confusion with jobs or activities. It also names the concrete endpoint (GET /api/v0/tasks). It stops short of explicitly distinguishing itself from get_task or the create_* siblings, so it is clear but not fully sibling-differentiated.

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 never says when to use this tool versus get_task (single record) or the sibling list_* tools, nor does it mention prerequisites or when to filter vs. page. It implies bulk retrieval of tasks only through the verb 'List'; no explicit context or exclusions are provided.

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