getFiles

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

Annotations already declare readOnlyHint=true, so the safe read-only nature is known. The description adds no behavioral details such as scoping to a project, pagination, or response format. It doesn't contradict annotations but provides minimal added value beyond them.

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, concise sentence with no wasted words. It is front-loaded with the core action and is appropriately terse, though it does not expand on anything else.

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 tool has a nested parameter object, no output schema, and zero schema descriptions, the description is far from complete. It lacks crucial details like what files are listed, the default behavior, return format, and any constraints. An agent would struggle to use this correctly without external documentation.

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 description coverage is 0%, so the description must compensate for the lack of parameter explanations. It fails to do so entirely, providing no meaning for 'format' or 'projectId' beyond what the schema's type and enum already convey. The nested structure with required fields is not explained.

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 clear verb ('List') and resource ('files'), making the basic purpose unambiguous. However, it does not differentiate from sibling tools like getAttachment or other list operations, and the term 'files' is somewhat ambiguous without context about what kind of files (project files? attachments?). It is clear but not fully distinguished.

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 is provided on when to use this tool versus alternatives such as getAttachment or other listing tools. There is no mention of use cases, prerequisites, or exclusions, leaving the agent to infer when this should be chosen.

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