Search character by ID Star Wars

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

No annotations are provided, so the description must cover behavioral traits. 'Search' implies a read-only operation, which is transparent. However, it does not disclose what happens if the ID is not found, the return format, or any potential side effects. For a simple lookup this may be sufficient, but more detail would improve clarity.

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, concise sentence that front-loads the verb and resource. It contains no filler, repetition, or unnecessary context, making it highly efficient.

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 one-parameter lookup tool with no output schema and no annotations, the description adequately conveys the tool's purpose and scope. It could mention not-found behavior or the expected response, but given the tool's simplicity, the current description is nearly complete.

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 single parameter 'id' as 'ID of the Star Wars character', giving 100% schema coverage. The description only adds the redundant word 'specific', which is already implied by fetching by ID, so it provides no additional semantic value 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 'Search a specific Star Wars character by ID' clearly states a verb ('search'), resource ('Star Wars character'), and scope ('by ID'), which is useful. However, it does not explicitly distinguish this from the sibling tool 'search_characters', which likely searches across characters generally.

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 versus alternatives. It does not mention that this should be used when you have a known ID, nor does it exclude it for other search scenarios. There is no explicit context or alternative naming.

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