pause_download

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

Annotations already signal a non-read-only, non-destructive mutation. The description goes further by disclosing batch partial-failure behavior: individual 405 refusals for already-paused/finished ids, successful pause of the rest, and whole-call invalid_parameter failure when none can be paused.

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 sentences, front-loaded with purpose, then the parameter, then error semantics. Every sentence earns its place with no redundancy.

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?

Output schema exists, so return values need not be explained. The description covers purpose, batch behavior, and error cases, though it omits permission requirements and explicit routing to resume_download, which would make it fully complete for an agent.

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 0% for the sole required parameter, task_ids. The description only repeats that it is a list, adding no format, source, or ID semantics beyond the schema's array type.

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 ('Pause') and resource ('download tasks'), with batch scope. Clearly distinguishes from siblings like resume_download, delete_download, and create_download without needing to name them.

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?

Implies usage via the verb and notes that already-paused or finished tasks are refused per id, which helps avoid invalid calls. However, it does not explicitly say when to choose this tool over alternatives such as resume_download or delete_download.

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