Behavior3/5

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint as false, indicating a safe read operation. The description adds context about output content (variant attributes, extensions, etc.) but does not reveal additional behavioral traits like pagination or rate limits.

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?

Single sentence with 12 words, no redundancy. Efficiently communicates the core purpose without extraneous text.

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

Completeness2/5

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

Despite having an output schema, the description is insufficient for a list tool with 5 parameters. It lacks details on pagination (cursor/limit), required assetId, filtering (extension, attributes), and when to use this tool over alternatives. The agent would struggle to invoke this correctly without additional documentation.

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

Parameters1/5

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

Schema description coverage is 0%, so the description must compensate. It only hints at 'variant attributes' and 'extensions' but fails to explain the purpose or format of parameters like assetId, limit, cursor, extension, and attributes. This leaves the agent uninformed about how to effectively use the parameters.

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

Purpose5/5

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

The description clearly states it lists official CC0 asset archives and specifies the returned fields: variant attributes, extensions, URLs, and byte sizes. It distinguishes from sibling tools like ambientcg_search_assets and ambientcg_get_asset, which focus on searching or getting single assets.

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?

No guidance on when to use this tool versus siblings (e.g., ambientcg_get_asset for single asset details, or polyhaven_list_files for Poly Haven files). No prerequisites, when-not-to-use, or alternative tool references.

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