joke_random

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

Annotations already declare readOnly, idempotent, openWorld and non-destructive, so the safety profile is covered. The description adds only the source API name; it says nothing about how randomness interacts with 'amount' (are 3 jokes guaranteed distinct?), rate limits of JokeAPI, or what happens when no category is given.

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 tight sentence with no waste and the purpose front-loaded. It is arguably too terse — one more clause on defaults or amount behavior would earn its place without bloat.

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 three-param read tool with full schema coverage and rich annotations, the essentials are covered. The remaining gap is the interaction between 'random' and 'amount'/'category' defaults, which neither schema nor description resolves, but no output schema means return shape is also unspecified.

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% — type, amount range (1-10), and the six categories are all documented in the schema. The description adds no parameter guidance beyond that, so the baseline of 3 applies.

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?

States a specific verb+resource ('Get a random joke') and names the backing source (JokeAPI), which implicitly separates it from dadjoke_random, chuck_random, and official_joke_random. It does not explicitly tell the agent how it differs from those siblings.

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 when-to-use, when-not-to-use, or alternative mentioned. The agent is left to infer from the sibling names that other joke tools exist and why this one would be chosen.

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