B3.4/5.0

Behavior3/5

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

The annotations already declare this as a safe, read-only, idempotent, non-destructive, non-open-world operation. The description adds scope context by specifying that assets live in the project CDN and can be filtered by folder, but it does not disclose return limits, pagination, or authentication requirements.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is front-loaded with the core action and scope, followed by a compact Args block. Every line is useful and there is no filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the low-complexity list operation, rich annotations, and the presence of an output schema, the description is mostly complete. It covers purpose and parameters, but stops short of explaining when to choose this tool over siblings or how folder paths relate to the CDN structure.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description must carry the parameter meaning. It adds the folder examples and optionality, but project_id is described only as 'The project ID,' which is nearly tautological and does not clarify format or source.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb (List) and resource (assets, files and folders) in a specific scope (project CDN). It clearly distinguishes the operation from mutating siblings like delete_assets or get_asset, though it does not explicitly name or differentiate those alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

There is no when-to-use guidance, no prerequisites, and no named alternatives. The description only says what the tool does, leaving the agent to infer that it should be used whenever asset enumeration is needed.

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