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

Annotations already declare openWorldHint=true, destructiveHint=false and readOnlyHint=false, so the agent knows this is a state-changing interaction in an open world. The description adds the shape of the result (scene, act, heard, next), which is genuinely useful with no output schema, but says nothing about failure modes, whether re-riding is allowed, or what 'visit' tracks.

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?

Three short sentences, front-loaded with the action and the return payload on the first two. The owner-priority rule is placed last but still reads cleanly; no filler.

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?

Covering the return payload compensates for the missing output schema, and the fireworks edge case is handled. However, with two required parameters and no schema descriptions, the unexplained 'visit' argument is a real hole for an agent trying to make a correct call.

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 0%, so the description must carry the parameter burden. It clarifies the 'fireworks' enum value and gives selection priority for a named ride, but never explains 'visit' (a required string), leaving half the inputs undocumented in both schema and description.

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 gives a concrete verb and resource ('Get on a ride') and explicitly carves out the special 'fireworks' variant. It does not contrast itself against siblings like 'enter' or 'status', so the boundary with those tools is left implicit.

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?

It supplies real sequencing guidance: fireworks come 'after your rides', and an owner-named ride should be taken 'first'. There is no explicit when-not-to-use clause or named alternative tool, so an agent still has to infer the boundary with 'enter'.

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