Download File to Local

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

The description provides no behavioral details beyond the basic action. With destructiveHint: true in annotations, the description should clarify that the tool writes to the local filesystem and may overwrite existing files. It omits side effects, error handling, and prerequisites, leaving significant gaps.

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 sentence, making it very concise. However, it is so minimal that it sacrifices completeness. A slightly longer description with key details would be beneficial without losing conciseness.

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 the large sibling set and the tool's complexity (2 required parameters, output schema exists), the description is insufficient. It lacks guidance on permissions, error behavior, and differentiating context. The output schema may cover return values, but other gaps remain.

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 both parameters have adequate descriptions in the schema. The tool description adds no extra meaning beyond what the schema already provides. Baseline 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 'Download a file from my Files.com site.' clearly states the action (download) and the resource (file from Files.com). However, it does not differentiate from sibling tools like Copy_File or Move_File, which have similar purposes. A more specific scope or usage context would improve clarity.

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?

There is no guidance on when to use this tool versus its siblings (e.g., Upload_File_from_Local, Copy_File). The description lacks any when-to-use or when-not-to-use criteria, leaving the agent to infer based on name alone.

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