cleanup_downloads_tool

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

No annotations provided, so the description carries full burden. It does not disclose whether the tool modifies or deletes data, what happens to files, or any side effects. 'Clean up' implies destructive action but lacks explicit confirmation, risking misuse.

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 short sentence, which is concise, but it omits crucial context. While it avoids fluff, it under-specifies the tool's behavior, making it less useful than a slightly longer but more informative description.

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?

Given no annotations and no output schema, the description must compensate. It fails to specify the scope of cleanup (e.g., all downloaded files vs. selective), whether it's reversible, or if user confirmation is needed. The two optional parameters suggest selectivity, but the description remains too vague.

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 is 100%, and each parameter already has a description in the schema. The tool's description adds no additional meaning beyond 'clean up downloaded files', so the baseline score of 3 is appropriate.

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 'Clean up downloaded files' uses a clear verb ('clean up') and resource ('downloaded files'), but it's vague about what exactly is cleaned (e.g., temporary files, cached data). It does not distinguish from siblings like 'download_geo_data' or 'get_download_stats', but the purpose is generally understandable.

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?

No guidance on when to use this tool versus alternatives. The description does not mention prerequisites, when cleanup is appropriate, or when to avoid it. With zero sibling differentiation, the agent receives no help in deciding to invoke this tool.

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