MCP Agent Debate

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and idempotentHint=true, covering safety and idempotency. The description adds that the output is a 'multi-round transcript', which provides some behavioral context beyond annotations. However, no additional traits like response format or side effects are disclosed.

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 very short (two lines plus example), which is concise but at the cost of omitting important details. It front-loads the purpose, but the lack of structure (e.g., no bullet points or sections) reduces usability. It is not overly verbose but is insufficiently informative.

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 6 parameters, including a complex nested object (chart) and enum (language), the description is severely incomplete. It does not explain the chart parameter's role in a debate, the expected format of agent strings, the output transcript structure, or language support. Without an output schema, the description fails to convey what the tool returns.

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 coverage is only 17% (only 'chart' has a description). The overall description only repeats the parameter names in the example and does not explain what 'agentA' and 'agentB' represent (e.g., persona descriptions), nor the purpose of 'chart' or 'language'. The schema includes details for 'chart' but the description adds little beyond that.

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 clearly states '2 personas debate a topic, multi-round transcript' which specifies the verb (debate) and resource (personas). The example request body further clarifies the required parameters. While it doesn't explicitly differentiate from siblings, the tool name and purpose are distinct enough among the MCP tools (e.g., mcp_multi_agent_coordinate).

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?

The description provides no guidance on when to use this tool versus alternatives. It lacks context about prerequisites, when not to use, or comparisons with sibling tools like mcp_multi_agent_coordinate or mcp_multi_chart_context. The example is shown but without usage advice.

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