dadjoke_by_id

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

Annotations already state readOnlyHint, idempotentHint, openWorldHint, and destructiveHint=false, so the safety profile is covered. The description adds no behavioral context beyond the basic operation, such as what happens when the ID is not found or whether the ID has a particular format.

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 no wasted words. It immediately communicates the action, resource, and lookup key.

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, single-parameter lookup with full schema coverage and rich annotations, the description is sufficient to invoke the tool correctly. It does not need to explain the safety profile, but it could be slightly more complete by noting how IDs are obtained or what happens for invalid IDs.

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%, and the single parameter is documented as 'Joke ID' in the schema. The description's phrase 'by its ID' restates that meaning without adding format, syntax, or validation details beyond the 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 gives a specific verb and resource: 'Get a specific dad joke by its ID.' The phrase 'by its ID' narrows the operation to a direct lookup, implicitly distinguishing it from sibling tools like dadjoke_random and dadjoke_search, though it does not explicitly name those alternatives.

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?

Usage is only implied: the caller should use this tool when they already have a joke ID. The description gives no explicit guidance on when to use dadjoke_search or dadjoke_random instead, nor does it explain how to obtain a valid ID.

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