get_list_members

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

Discloses pagination with cursor and default/max count, but no annotations exist. Does not cover potential behavioral traits like rate limits, permissions, or handling of private lists.

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?

Concise with an Args section; front-loaded main purpose. Could be slightly more compact but overall well-structured without wasted words.

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?

Adequate for a simple paginated list tool; output schema exists so return values are covered. Lacks error handling or authentication details. With no annotations, could be more 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?

Description explains each parameter with details (list_id, count with default/max, cursor usage) beyond the schema's type and default values, adding significant value.

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?

Clearly states 'Get members of a Twitter List (paginated)' with specific verb and resource, and pagination hint distinguishes it from siblings like add_list_member and remove_list_member.

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 on when to use this tool versus alternatives (e.g., get_list_tweets, get_lists) or when not to use it. Only describes functionality without context.

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