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

With no annotations, the description is expected to carry the burden of disclosure. It provides no information regarding scope, rate limits, or specific behavioral traits beyond simple listing.

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 definition is very concise, using two short sentences to convey the core function and primary parameter capability. It is efficient and readable.

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 lack of an output schema, the description lacks completeness. It does not specify what information is returned for each asset (e.g., name, size, status), making the agent's expectation ambiguous.

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 description only mentions the 'projectId' filter. Since the schema defines 'fileType' as a second parameter/filter which is not mentioned in the description, the description fails to add value to the semantics of the full input structure. Coverage is weak.

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 clearly defines the action (List) and the resource (user's uploaded assets). It distinguishes the intent from generic listing actions, although it does not explicitly name the sibling tools it is distinct from.

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?

It merely notes that a 'projectId' filter is optional. It offers no guidance on when to use this tool versus others (like `list_projects`) or under what conditions the filters apply.

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