get_club_members

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

There are no annotations, so the description must carry the full burden of behavioral disclosure. It does not state whether this is a read-only operation, any authentication or rate-limit requirements, or what the response format looks like. The single sentence offers no behavioral context beyond the 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 sentence with no superfluous words; it is appropriately concise for a simple retrieval tool. However, it is so brief that it lacks helpful detail that could be included without adding much length, so it is efficient but not fully front-loaded with useful context.

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 tool with one required parameter and no annotations, output schema, or parameter descriptions, the definition is incomplete. It does not clarify what 'url_id' refers to or what the response contains. An agent cannot reliably invoke this tool correctly without additional information.

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 the sole required parameter 'url_id'. The agent has no clue what value to provide (e.g., the club's URL slug). The description adds no meaning beyond the parameter name, leaving the agent to guess.

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 a clear verb ('Get') and resource ('members of a club'), and the platform (Chess.com). It distinguishes from siblings like get_club_profile and get_club_matches by focusing on the member list. However, it does not elaborate on what 'members' includes (e.g., usernames, avatars, joined dates), so it is clear but not richly specific.

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 on when to use this tool versus alternatives. It does not mention any conditions, exclusions, or related tools. The usage is only implied by the name and description, which is minimal.

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