events_details_by_url

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

No annotations are provided, so the description carries full burden for behavioral disclosure. 'Get events details' implies a read-only operation but doesn't specify authentication requirements, rate limits, error conditions, or what format/details are returned. For a tool with zero annotation coverage, this leaves significant behavioral gaps.

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 ('Get events details') but under-specified rather than efficiently informative. While it's brief, it fails to provide necessary context about what 'events' means or how this differs from similar tools, making it more of an incomplete placeholder than a well-structured description.

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 lack of annotations, no output schema, and multiple sibling tools with similar names, the description is inadequate. It doesn't explain what 'events' refers to, what details are returned, or how this differs from 'events_details_by_id' or 'search_events'. For a tool in this context, more specificity is needed.

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 tool has zero parameters (schema coverage 100%), so there's no parameter information needed in the description. The baseline for zero parameters is 4, as the description doesn't need to compensate for any parameter documentation gaps.

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 'Get events details' is a tautology that essentially restates the tool name 'events_details_by_url' without adding meaningful clarification. It doesn't specify what 'events' refers to in this context or what kind of details are retrieved, nor does it differentiate from sibling tools like 'events_details_by_id' or 'search_events'.

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 no guidance on when to use this tool versus alternatives. With sibling tools like 'events_details_by_id' and 'search_events' available, there's no indication whether this tool is for retrieving events by URL specifically, what context it applies to, or any prerequisites for its use.

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