event_set_name

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

No annotations are provided, so the description carries the full burden. It states the action 'Rename' but does not disclose potential side effects, permissions, or reversibility. Since renaming is a mutating operation, the description should at least hint at whether it modifies an existing event or has any constraints. It also doesn't mention output or error behavior.

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 concise: one line plus a parameter list. It is front-loaded with the main purpose. The parameter list is clear and efficient. No waste, but it could be slightly more informative without becoming verbose.

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 that there is no output schema and no annotations, the description is incomplete for a mutating tool. It lacks behavioral details, error conditions, or any note about validation. It also doesn't cover potential edge cases (e.g., renaming to an existing name). It is adequate for a trivial rename, but not sufficiently complete for a tool with no other structured info.

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% because the input schema only provides titles ('Name' and 'Target') without descriptions. The description adds minimal value by explaining 'target: event:// path or {guid}' and 'name: New name.' This clarifies the format of target, but it does not describe constraints, examples, or behavior for the name parameter. Since coverage is very low, the description must compensate, but it barely does.

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 clearly states the tool's function: 'Rename an event.' It specifies the resource type (event) and the action (rename). Although it doesn't explicitly distinguish from siblings like 'event_set_folder' or 'sound_set_name', the verb 'rename' is specific enough for an event-related tool.

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?

No guidance on when to use this tool versus alternatives. It does not mention any context, prerequisites, or alternatives. For a simple rename operation, the description implies usage, but there is no explicit 'when to use' or 'when not to use'.

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