get_available_filters

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

No annotations are provided, so the description carries the burden. The verb 'Get' clearly indicates a read-only, non-destructive operation. There are no side effects, rate limits, or other behavioral traits to disclose for such a simple tool, so the description adequately covers transparency.

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, efficient sentence that front-loads the verb and resource. Every word earns its place, with no unnecessary elaboration or repetition.

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 zero-parameter, no-output-schema tool, the description is complete enough. It identifies the returned data categories. It does not specify the exact format (e.g., array of objects, separate lists), but this is a minor gap for a simple list retrieval.

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?

The tool has zero parameters, so there is nothing to document beyond the schema. The description adds value by specifying exactly what data is returned (platforms and genres), which helps the agent understand the output without needing an output schema.

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 ('Get') and the resource ('available platforms and genres') with a clear purpose ('for filtering'). It is immediately distinct from the sibling tools, which all focus on recommendations, search, or content details.

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 tool is a simple lookup utility with no parameters. Its purpose is clear from the description, and it is not ambiguous when to use it compared to siblings. However, it does not explicitly mention alternatives or provide any contextual 'when to use' guidance, but the distinct nature makes that unnecessary.

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