set_group_add_request

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

With no annotations provided, the description carries the full burden of behavioral disclosure, yet 'Handle group join request' reveals nothing about side effects, required permissions, outcome of approval or rejection, or reversibility. An agent cannot anticipate what happens when calling this 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 short sentence, which is structurally concise, but it is under-specified and doesn't earn its place by clarifying behavior. It is too vague to be considered effective, resembling a placeholder rather than a useful one-liner.

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 four parameters, no annotations, and no output schema, this description is severely incomplete. An agent lacks sufficient information about prerequisites, effects, or return values to call it confidently.

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 100%, so the schema already explains flag, reason, approve, and sub_type. The description adds no parameter context, leaving the baseline of 3 appropriate for a tool whose schema fully documents its parameters.

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 names a resource (group join request) but uses the vague verb 'handle,' which doesn't specify whether the action is approving, rejecting, or otherwise managing the request. It is too generic to distinguish clearly from related tools like set_friend_add_request or get_group_system_msg without inspecting the schema.

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?

There is no guidance on when to use this tool versus alternatives. The schema implies approving/rejecting a request, but the description never states the trigger condition, such as 'when a group join request is pending' or 'instead of set_friend_add_request for group requests.'

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