etsy_listings_stats_bulk

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

The annotation 'readOnlyHint: true' already discloses the read-only nature. The description adds no additional behavioral context (e.g., rate limits, authentication needs, or pagination behavior). Since the annotations cover the safety trait, the description's value is minimal beyond restating the obvious.

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 extremely concise (6 words) and front-loaded. Every word is meaningful, but the brevity may omit useful context about what stats are returned. Still, for a simple bulk operation, it is appropriately sized and efficient.

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 no output schema and no description of the return value, the agent has no information about what 'stats' are provided (e.g., views, favorites, sales). The simple schema (one parameter) reduces complexity, but the lack of return information makes the description incomplete for informed decision-making.

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%, and the description in the schema already explains the parameter 'listing_ids' as 'Listing IDs to fetch stats for'. The tool description adds no extra meaning or context to the parameter beyond what is in the schema. Baseline score of 3 applies.

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 the action ('Get stats') and the resource ('multiple listings'), distinguishing it from the sibling tool 'etsy_listing_stats_get' which targets a single listing. The verb-resource pairing is specific and unambiguous.

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 implies usage for fetching bulk stats but provides no explicit guidance on when to use this tool versus alternatives like 'etsy_listing_stats_get' (single listing) or 'etsy_listings_get_by_ids' (which likely returns different data). No when-not-to-use or context exclusions are mentioned.

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