get_random_joke

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

There are no annotations, so the description must carry the full burden. It only states 'Retrieve a random cat joke' without disclosing the effect of the optional 'category' parameter, which is a key behavioral trait. It also does not mention any side effects, permissions, or rate limits, though as a read-only operation this may be less critical. The description adds no context beyond the schema.

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 a single, front-loaded sentence with zero filler. It states exactly what the tool does in the fewest possible words.

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 simple read tool with an output schema and full parameter documentation, the description is minimally sufficient. However, it does not mention the optional category filter or differentiate from sibling tools, leaving some context to be inferred. Given the low complexity, a score of 3 is appropriate.

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 the single optional 'category' parameter, so the baseline is 3. The description adds no additional meaning beyond what the schema already provides, but since the schema is fully descriptive, the agent has enough information to use the parameter correctly.

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 uses a specific verb ('Retrieve') and a clear resource ('a random cat joke'), which immediately distinguishes this tool from siblings like 'list_categories' and 'search_jokes'. The purpose is unambiguous and concise.

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 no guidance on when to use this tool compared to the siblings. It does not state that this is for retrieving a single random joke, whereas search_jokes would be for searching with criteria, or list_categories for browsing categories. No alternatives or exclusions are mentioned.

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