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

Annotations already declare readOnlyHint=false, idempotentHint=true, openWorldHint=true, and destructiveHint=false. The description adds one behavioral detail: the request avoids a plaintext introduction, but it does not explain permissions, side effects, or what a successful request triggers.

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 front-loaded sentence with no filler. It is concise, though its brevity contributes to ambiguity rather than precision.

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?

Although an output schema exists, the description does not compensate for undocumented required parameters, lacks usage guidance, and gives minimal behavioral context for a non-read-only tool. It is not sufficient for an agent to invoke confidently without opening the schema.

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% for two required parameters. The description only loosely hints at contextId ('in this context') and matchRequestId ('with a suggestion'), without explaining formats, constraints, or how the IDs are obtained.

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 an action ('Request a chat') and a context ('in this context'), but 'with a suggestion' is vague and it does not distinguish this from siblings such as start_chat or panel_chat. An agent can infer the general purpose but not the precise distinction.

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 explicit guidance on when to use this tool versus start_chat, panel_chat, or request_human_match. The phrase 'without sending a plaintext introduction' describes a constraint, not a routing condition.

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