get_tonight

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

With no annotations provided, the description fails to disclose behavioral traits such as read-only nature, authentication requirements, or rate limits. It only states the operation ('Get'), which implies a read, but offers no additional safety or side-effect information.

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 exceptionally concise, using two sentences to convey purpose and a key usage note. It is front-loaded with the primary function and avoids any 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?

Despite having a complex input schema (5 optional parameters) and an output schema, the description provides minimal context. It does not explain pagination (limit/offset), filtering (genre/area), or output structure, leaving the agent under-informed for effective use.

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 input schema has 5 parameters with 0% description coverage, and the description provides no explanation or guidance on any parameter. The user must infer the meaning of city, genre, area, limit, and offset from context, making the tool difficult to invoke correctly.

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 tool retrieves 'tonight's nightlife events and open VIP venues', using the verb 'Get' and specifying the resource. It distinguishes from sibling tools like search_events and get_event_details by focusing on the 'tonight' scope.

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 includes a usage hint ('Always check vip_venues_open — VIP clubs are open even without listed events') but lacks explicit guidance on when to use this tool versus alternatives like search_events. It implies context for VIP venues but does not specify exclusions or conditions.

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