get_categories

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

With no annotations provided, the description carries the full burden and does well by disclosing key behaviors: it returns a CategoryMap object, includes both main and subcategories, and lists common category examples. It does not cover potential limitations like rate limits or auth needs, but provides useful context beyond basic functionality.

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 well-structured and front-loaded, starting with the core purpose and return value, followed by examples and usage scenarios. Every sentence adds value, such as explaining category organization and practical applications, with no wasted words or redundancy.

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's low complexity (0 parameters), high schema coverage (100%), and presence of an output schema (true), the description is complete. It explains what the tool does, what it returns, and how to use the output, covering all necessary context without needing to detail parameters or return values explicitly.

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 0 parameters, and schema description coverage is 100%, so the baseline is 4. The description appropriately does not discuss parameters, focusing instead on output and usage, which adds value without redundancy.

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 verb 'Get' and resource 'mapping of all forum categories', specifying it returns a CategoryMap object. It distinguishes from siblings by focusing on category mapping rather than topics, posts, users, or other forum entities, making the purpose specific and differentiated.

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 description provides clear context on when to use this tool, such as for filtering search results, understanding topic sections, and navigation. However, it does not explicitly state when not to use it or name alternatives among sibling tools, leaving some guidance implicit rather than explicit.

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