get_latest_friends

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

With no annotations and a minimal description, behavioral traits like pagination, rate limits, authentication needs, or default behavior for missing parameters are not disclosed. The description adds little beyond the bare action.

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 short sentence, which is concise but lacks any structure. It is minimally viable with no unnecessary words, but also no informative organization.

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?

Given four parameters and no annotations, the description is too sparse. It does not cover pagination, filtering, or output format context, even though an output schema exists. The agent lacks sufficient information to use the tool effectively.

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 0%, and the description does not explain any of the four parameters (count, cursor, user_id, screen_name). This is a critical gap, as the agent cannot understand parameter purpose or valid values.

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 states 'Retrieves the latest friends (following users)', which identifies the verb and resource. However, it does not differentiate from sibling tools like get_user_following or get_latest_followers, leaving ambiguity about what 'latest' means and how this tool is unique.

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?

No guidance is provided about when to use this tool versus alternatives, such as get_user_following or get_latest_followers. There is also no mention of prerequisites or context for effective use.

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