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

Annotations carry only a title, so the description does the heavy lifting and delivers: the change is a live link, prior sounds are removed from each event's list, and it neither generates nor spends credits. These are exactly the side effects an agent needs before mutating sound assignments. Only the response/confirmation behavior is left unstated.

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?

Dense and front-loaded, with the core action first and side effects after. The semicolon-chained clauses make it slightly run-on, but every sentence contributes a distinct behavioral fact rather than 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?

For a mutation tool with no annotations and no output schema, the description covers side effects well, but it omits what happens with an invalid or empty event_ids list and never explains generation_id or the scope boundary between event_ids and same_name. Adequate but with a real gap around the required parameter.

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 coverage is 0%, so the description must document all three parameters and it only covers two partially: same_name is explained well, event_ids is implied by 'several events' with no array/limit details, and the required generation_id is never mentioned at all. That leaves the most important required parameter unexplained 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?

States a specific verb and resource (make several events play one event's sound) and gives a concrete example ('the same Building on all buildings'). It never names a sibling to contrast with, so differentiation is left to inference, but the operation itself is unambiguous.

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 use case is implied rather than stated: you infer this is the tool for propagating a sound across events rather than picking one (choose_sound) or saving one (save_sound). There is no explicit when-not guidance, though the live-link warning implicitly steers agents away from using it as a throwaway copy.

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