clear_downloads

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It states the action ('clears all files') and scope ('downloads folder'), but it does not disclose whether the deletion is permanent, whether files go to trash, if any confirmation is required, or what the result/return value looks like. For a destructive operation, this is a significant gap.

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?

A single, front-loaded sentence contains the entire definition with no filler or repetition. Every word adds meaning and the structure is ideal for quick scanning.

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 zero-parameter tool, the description covers the basic what and where, which is minimally viable. However, it lacks critical context for a destructive operation: whether deletion is irreversible, what 'downloads folder' refers to (e.g., system default vs. app-specific), and what happens after execution. With no annotations and no output schema, this leaves the agent without enough safety-relevant information.

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 there are no parameter semantics to explain. The description's clarity about the action and target makes the lack of params expected and non-confusing. Baseline for zero-parameter tools is 4.

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 a specific verb ('clears') and a specific resource ('files from the downloads folder'). It is immediately distinguishable from the sibling tools extract_video_info and download_video, which are about video retrieval and saving, not deletion.

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 tool's purpose is self-evident and clearly disjoint from the siblings, so an agent can infer when to use it. However, the description gives no explicit when-to-use guidance, no mention of alternatives, and no warning that clearing is destructive and should be used only when intended.

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