Get clan member list

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

The description provides no behavioral details such as read-only status, permissions, or side effects. Since annotations are absent, the description should compensate but does not. An agent cannot infer whether this operation is safe or requires authentication.

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 extremely brief (5 words) but lacks substance. It is not front-loaded with critical information; instead, it omits details that could fit concisely. The brevity here sacrifices usefulness.

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 parameter and no output schema, the description should at least clarify what the roster contains (e.g., player tags, names). It does not, leaving the agent uncertain about the response format. Contextually incomplete for effective invocation.

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 has one required parameter 'tag' with zero description. The description adds no explanation (e.g., that tags are prefixed with '#'), leaving the agent without guidance on proper formatting or required values. Schema coverage is 0% and the description fails to compensate.

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 'Member roster for a clan.' indicates the tool retrieves a list of clan members, which is clear but vague. The title 'Get clan member list' reinforces the purpose. However, it does not explicitly state the game (Clash Royale) or distinguish from sibling tools like coc_get_clan_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 guidance is provided on when to use this tool versus alternatives. Sibling tools exist for different games (coc_, bs_), but the description lacks any selection criteria or context, leaving the agent to rely solely on the tool name.

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