get_featured_categories

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

The description implies a read-only operation by describing what it returns (games, categories), but it does not explicitly state that no modifications occur, nor does it mention any authorization or rate limits. Since no annotations are provided, the description carries the burden but falls short of fully disclosing behaviors.

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 two sentences, no redundant information, and front-loaded with the core action and result. Every sentence earns its place.

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 the tool has no parameters and no output schema, the description adequately explains what the tool does and what is returned. However, it could be more complete by distinguishing it from the similar-sounding 'get_featured_games' sibling 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?

There are no parameters, so the schema covers all input requirements. The description adds value by explaining the output structure (categories with games, prices, discounts), which is helpful for understanding what the tool returns 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 clearly states it retrieves Steam store featured categories and lists examples of categories and included data (names, prices, discounts). However, it does not explicitly differentiate from the sibling tool 'get_featured_games', which might have a similar but distinct purpose.

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 is provided on when to use this tool versus alternatives, such as 'get_featured_games' or other game-listing tools. The context of use is entirely implied.

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