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

No annotations are provided, so the description bears full responsibility for behavioral traits. It only states the action without disclosing effects (e.g., notifications to users, irreversibility, permission requirements, rate limits). For a mutation action, this is insufficient.

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 unnecessary words. It is concise but lacks structure (e.g., bullet points or sections). While efficient, it could be slightly more organized for clarity.

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 simple rejection tool with three required parameters and no output schema, the description covers the basic purpose. However, it omits details like the requirement of admin permissions or that only pending requests can be rejected. Completeness is adequate but has gaps.

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 covers 100% of parameters with descriptions (groupId, accountId, requestIds). The tool description does not add extra meaning beyond the schema. A baseline of 3 is appropriate as the schema already does the heavy lifting.

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 name and description clearly state the action: rejecting pending join requests for a WhatsApp Group. It distinguishes itself from sibling tools like 'approve' and 'list' join requests. The verb 'reject' and resource 'whatsapp_group_join_requests' are specific and unambiguous.

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 this tool vs. alternatives (e.g., approve or list). While siblings provide context, the description lacks when-not-to-use advice or prerequisites. It is adequate but leaves some ambiguity for agents.

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