BetaSeries: friends

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

With no annotations, the description carries the burden of behavioral disclosure. It provides HTTP methods (GET vs POST/DELETE) that imply side-effect profiles, and it gives specific behavior for get-friends-list (defaults, optional id, blocked/summary flags). However, it omits auth requirements, rate limits, error handling, and response structure, so transparency is moderate.

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 introductory instruction followed by a line-per-operation list. It is somewhat lengthy due to repeated 'Params:' phrasing, but every included detail serves a purpose and adds practical information. It could be more compact, but is not wasteful.

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 multi-operation tool with no output schema and no annotations, the description covers all operations and parameters but lacks return value details and error behavior. The complexity is high (6 operations), and while the parameter information is thorough, an agent cannot fully anticipate what the API will return or what errors may occur, leaving a notable completeness gap.

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 only defines params as a generic object of string key-value pairs, making the description the sole source of parameter meaning. Each operation lists parameter names, optionality, and semantic purpose (e.g., 'id? (Member ID to unblock)'), adding essential context beyond the schema. This is excellent parameter documentation.

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 identifies this as the BetaSeries 'friends' API and enumerates all supported operations (delete, get, post) with specific resources and actions. It distinguishes itself from sibling tools by focusing exclusively on friends-related endpoints, leaving no ambiguity about what the tool does.

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 implies usage for friend management operations but does not explicitly state when to use this tool versus alternatives. There is no mention of exclusions or conditions where another BetaSeries tool might be more appropriate, though the 'friends' naming provides some contextual guidance.

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