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

The readOnlyHint annotation already establishes that this is a safe read operation, so the description adds some value by disclosing ordering ("newest first") and scope ("including ones started on the website"). However, it does not mention pagination behavior, default limit behavior, or any auth/rate-limit context beyond the annotation.

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?

The description is a single efficient sentence with zero waste. It is front-loaded with the action and resource, then adds ordering and scope details.

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 simple read-only list tool with one optional parameter, the description covers purpose, ordering, and cross-source inclusion well. It is slightly incomplete because it does not explain the limit parameter or pagination behavior, but no output schema exists and the annotation already carries the safety profile.

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 coverage for the single limit parameter is 0%, and the description does not mention the parameter at all. The parameter name "limit" is fairly intuitive, but the description adds no meaning about what it limits, its default, or how it interacts with the maximum of 50.

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 description gives a clear verb and resource ("List your upscale tasks") and adds useful scope details: newest first and includes website-started tasks. It implicitly separates itself from get_task by being a plural listing operation, though it does not explicitly name alternatives.

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 phrase "List your upscale tasks" implies the tool should be used when the agent needs a task list, but there is no explicit guidance on when not to use it or when to prefer get_task instead. The usage context is present but left implicit.

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