BetaSeries: persons

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

With no annotations, the description carries the burden. It discloses the HTTP methods (GET) and optional parameter defaults (with_user default 0), implying read-only behavior. However, it does not mention authentication, rate limits, or response format, leaving some transparency gaps.

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 well-structured with a clear lead sentence and a bulleted operation list. It is not overly verbose, but the operation list repeats some information that could be seen as slightly redundant with the schema's enum values.

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?

The description covers all operations and parameter details, which is sufficient for basic invocation. However, with no output schema, it does not describe the response structure or error behavior, and it omits any authentication or rate-limit notes. For a simple read-only API this is acceptable but not 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 schema only provides a generic params object, so the description is essential. It explicitly lists each operation's parameters, marks optional ones with '?', and explains their meaning (e.g., 'with_user? Adds the connected user progression...'). This adds significant 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 clearly states it calls the BetaSeries persons API and lists specific operations with verbs like 'Display news articles' and 'Display details of the actor.' It distinguishes from siblings by resource name, but does not explicitly compare to alternative tools.

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 tells the agent to pick an operation and pass params, implying it should be used for persons-related data, but it provides no explicit exclusions or named alternatives. Sibling tools are implicitly differentiated by resource only.

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