Search about Star Wars Character

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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, so the agent knows this is a safe read operation. The description adds no extra behavioral context such as response format, error behavior, or rate limits. It does not contradict annotations, but also provides no additional transparency beyond them.

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 efficiently communicates the core purpose without 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?

For a simple one-parameter tool with annotations covering safety, the description is minimally adequate. However, it does not specify what 'information' is returned, and since there is no output schema, this gap is notable. An agent would not know if this returns a full bio, a summary, or just a reference to another resource.

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?

The input schema fully describes the 'name' parameter with 100% coverage, so the baseline is 3. The description mentions 'specific' character, which adds a slight nuance (singular vs plural) but does not meaningfully enhance understanding 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 clearly states it searches for information about a specific Star Wars character, using a specific verb and resource. However, it does not explicitly distinguish from sibling tools like get-information-of-star-wars-characters or get-list-of-star-wars-information, though 'specific' implies a single vs multiple distinction.

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 usage context is implied by 'specific character'—it's for single-character queries. However, there is no explicit guidance on when to use this tool versus the siblings, no exclusions, and no mention of alternatives. The agent must infer the differentiation from the tool name and description.

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