download_file

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

Annotations include destructiveHint=false, which covers safety profile. The description adds no further behavioral context — no mention of permissions, whether the file is a snapshot of current state, or any side effects. With sparse annotations, the description could explain what 'download' implies but does not.

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?

Single sentence, concise and front-loaded. However, it omits important details about tool behavior and alternatives, making it under-specified rather than efficiently concise. No wasted words, but also no substance beyond a basic statement.

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 simple download tool with no output schema and minimal annotations, the description is too brief. It does not clarify the distinction between this and sibling download tools, nor does it explain any caveats like 'snapshot' semantics or whether the file is binary/text. Insufficient for an agent to reliably choose this tool.

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 50%; only output_path has a description. The description does not explain the 'path' parameter (what it refers to, format, or scope). The tool description adds no value beyond the schema for parameters, failing to compensate for the undocumented 'path'.

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 states a specific action ('Download') and resource ('document snapshot or binary file') from the 'open project'. It is clear but does not differentiate from sibling tools like download_project or download_output, which also involve downloading. Lacks specificity on what counts as a 'document snapshot'.

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 such as download_project or download_output. No context on prerequisites, project state, or typical use cases. Leaves the agent to infer usage.

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