clear_downloads

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

No annotations are provided, so the description carries full behavioral disclosure burden. While "buffer" hints at an internal tracking list rather than files, it does not explicitly state whether downloading files are affected, whether the action is irreversible, or what the side effects are. This is a potentially destructive operation.

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, front-loaded sentence with no wasted words. It conveys the essential purpose efficiently.

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?

The tool is simple with no parameters and no output schema, but given the lack of annotations, the description should provide more behavioral context (e.g., whether it clears the internal buffer only, whether it deletes files). The word "buffer" implies non-destructive-to-files, but this is not explicit, leaving some ambiguity.

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?

The tool has zero parameters, so the description does not need to add parameter semantics. The baseline for 0 params is 4, and the description adequately covers the no-parameter nature.

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 uses the specific verb "clear" and identifies the resource as the "tracked downloads buffer," making the tool's function clear. It distinguishes itself from siblings like list_downloads (which lists) and set_download_behavior (which sets behavior).

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 implies use when you want to reset the downloads tracking buffer, but it does not explicitly state when to use this tool vs alternatives or mention any exclusions. No alternatives are referenced from the sibling set.

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