Behavior2/5

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

No annotations are provided, so the description carries the full burden. It offers no behavioral information such as whether this is a read operation, authentication requirements, rate limits, or the nature of the response. The existence of an output schema helps but the description itself is opaque.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness3/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is extremely concise at 4 words, but it sacrifices clarity and completeness. While brevity is valued, the description fails to convey essential information, making it under-specified rather than efficiently concise.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool has two required parameters and an output schema, the description is insufficient. It does not explain the prerequisite of starting a download job, the expected state of the job, or what the response contains. The output schema partly compensates, but the description lacks contextual ties.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100% with both parameters having clear descriptions in the schema. The description does not add any additional meaning or context beyond what the schema already provides, so baseline score of 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Get a list download' clearly identifies the action and resource, distinguishing it from the sibling tool 'slack_lists_download_start' which initiates the download. However, it lacks specificity about what 'get' entails (e.g., retrieving status, file content, or metadata).

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. It does not indicate that it should be used after starting a download job with 'slack_lists_download_start', nor does it mention any prerequisites or conditions.

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