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

No annotations are provided, so the description carries the full behavioral burden, yet it discloses almost nothing: it does not mention that results are paginated (limit/offset exist), how they are ordered, what the return shape is, or what the geography filter actually excludes. The one useful hint is the hard geographic constraint, but that is thin for a no-annotation tool.

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?

A single front-loaded sentence with no filler or redundancy. It is efficient, though the brevity borders on under-specification rather than true conciseness.

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?

For a 5-parameter tool with no annotations and no output schema, the definition is too sparse. It omits what 'marketing events' are, valid category values, pagination behavior, and any tie-break against the many sibling event 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?

Schema description coverage is 100%, so the schema already documents date, limit, offset, category, and neighborhood, and a baseline of 3 applies. The description only reinforces the neighborhood geography; it adds nothing about valid category values or pagination semantics beyond the schema.

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?

States the resource ('Events') and adds a geographic scope (San Francisco, Oakland, or Berkeley) plus a neighborhood dimension, so the agent grasps roughly what is returned. However, it never explains what 'marketing' means here or how it differs from the many event siblings (get_events, get_venue_events, get_happening_today, get_weekend), so the distinguishing purpose is left to inference.

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?

There is no when-to-use guidance at all. With roughly a dozen event-fetching siblings in the tool list, the description gives the agent no basis for choosing this tool over get_events, get_venue_events, or get_weekend, and no stated prerequisites or exclusions.

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