list_realtime_presets

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only suggests a read-only action via the verb 'List' but provides no details about scoping, pagination, response shape, or dependencies (e.g., requiring an existing app). The input schema hints at app scope, but the description itself adds no behavioral context.

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 extremely concise with no unnecessary words, and the verb is front-loaded. It loses a point because the brevity borders on under-specification, but it is not bloated.

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?

The tool has two required params, no annotations, and no output schema, so the description needs to compensate by explaining what presets are, their relationship to Realtime apps, and any relevant constraints. The single phrase 'List Realtime Kit presets' is insufficient for an agent to confidently select and invoke the tool.

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% for both app_id and account_id, so the schema already documents the parameters. The description adds no parameter-level details, but the baseline of 3 is appropriate when the schema handles the semantics.

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 states a specific verb ('List') and resource ('Realtime Kit presets'), which clearly identifies the tool's purpose. However, it does not explicitly differentiate this from sibling tools like list_realtime_apps or get_realtime_preset, so it stops short of a 5.

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 guidance about when to use this tool versus alternatives, no mention of prerequisites, and no explanation of what Realtime Kit presets are. The agent must infer usage entirely from the tool name and schema.

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