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

With no annotations, the description carries the full behavioral burden and discloses almost nothing beyond the word 'upcoming' — no note on pagination, ordering, whether past events are excluded, or return shape. It does not contradict anything, but it adds little behavioral context for a read 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 six-word fragment with zero padding and the scope front-loaded. It is efficiently sized, though the terseness comes at the cost of completeness rather than being optimally balanced.

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 callable read tool with two parameters, no annotations, and no output schema, the description leaves too much unstated: it never links the 'id' parameter to the mentioned venue, says nothing about the 'limit' semantics, and gives no guidance on when to prefer it over the many event-related siblings.

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% (id and limit are documented in the schema), so the baseline is 3. The description adds no parameter meaning beyond the schema and does not clarify that the 'id' is the venue/listing identifier referenced by 'one venue'.

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 names the resource (events) and constrains scope to a single venue and to upcoming (future) occurrences, so an agent can tell it returns a venue-specific event list rather than a global feed. It stops short of naming the sibling it contrasts with (e.g. get_events), so it is clear but has no explicit sibling differentiation.

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, no statement of preconditions, and no reference to alternatives such as get_events, get_happening_today, or get_weekend. The agent must infer from the name alone when this tool is the right choice.

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