chromewebstore_charts

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

No annotations are provided, so the description carries full burden. It discloses that the tool returns 'item cards' and lists defaults, but does not describe the return format (e.g., fields in each card), pagination behavior, or that it is a read-only operation. More context on the response structure would improve transparency.

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 concise with two sentences plus a defaults list. It is front-loaded with the core purpose and every sentence adds value without redundancy.

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's simplicity (listing with optional filters) and lack of output schema, the description covers the core functionality and defaults. However, it does not specify what fields the returned 'item cards' contain, which would be helpful for an agent to interpret results.

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%, so baseline is 3. The description adds value by specifying exact accepted values for the 'chart' parameter (trending, popular, notable) and providing defaults for all parameters, which is not in the schema descriptions.

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 states 'List a Chrome Web Store top chart', specifying the verb 'List', resource 'Chrome Web Store top chart', and distinguishing from siblings like chromewebstore_search (which searches). The accepted chart values (trending, popular, notable) add specificity.

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?

The description provides defaults for all parameters and acceptable chart values, giving clear context for usage. However, it does not explicitly mention when to use this tool versus alternatives like chromewebstore_search or chromewebstore_category, which could be helpful.

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