events_by_category

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It only states the action without mentioning result format, pagination (e.g., size parameter), or any limitations. The 'browse' phrasing suggests a read operation, but no specifics are given.

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 a single sentence that is direct and front-loaded with the action. It is concise but includes imprecise category examples that could be removed without loss of meaning.

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 low complexity, the description is too sparse. It lacks any mention of output structure, sorting, or interaction with the size parameter. Moreover, the absence of usage guidance relative to siblings makes the tool contextually incomplete for an agent selecting among similar tools.

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 schema covers 'city' and 'category' with descriptions, and the tool description adds examples of categories, though these are inconsistent with the enum. The 'size' parameter has no description in schema or description, leaving one parameter semantically undocumented. The description adds marginal value but does not fully compensate for the missing size semantics.

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 uses the verb 'browse' and specifies the resource 'events in a city filtered by category,' making the core purpose clear. It distinguishes from siblings like search_events and get_event_details by focusing on category-based browsing. However, the example categories (Family, Comedy) don't match the actual enum values, introducing minor confusion.

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?

No guidance is provided on when to use this tool versus sibling tools such as search_events or weekend_events. The description implies usage for browsing by category, but there is no explicit exclusion or alternative mention, leaving the agent to infer the appropriate context.

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