remove_list_member

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

No annotations are provided, so the description carries the full burden. It merely restates the action without disclosing behavioral traits like side effects (e.g., irreversible removal), authorization requirements (e.g., must be list owner/editor), or error conditions (e.g., if user not in list). This is insufficient for a mutation tool.

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, clear sentence with no unnecessary words. It efficiently conveys the core functionality, earning its place.

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 tool is simple with two required parameters and an output schema (not provided). The description covers the basic action but lacks context like expected outcomes or usage hints. Given the simplicity, it is minimally adequate but not comprehensive.

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 coverage is 100%: both parameters (list_id, user_id) are described in the schema as integers. The description adds no additional meaning beyond the schema (e.g., where to find these IDs, constraints). Per rules, baseline is 3, so this score is adequate.

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 the action: 'Remove a user from an X/Twitter list.' It uses a specific verb ('Remove') and identifies the resource (user from list), effectively distinguishing it from siblings like 'add_list_member' and 'get_list_members'.

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 explicit guidance on when to use or not use this tool versus alternatives. The description does not mention prerequisites (e.g., the user must be a member, list ownership required) or provide context for potential errors, making it less helpful for an agent to decide when to invoke it.

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