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

The description discloses substantial behavioral detail beyond the annotations: it runs a live exchange, privately hands on one speaker and one aim at a time, hides the other side from each speaker, controls turn order, and ensures neither position is predesigned to lose. It also names the return artifacts (matchup card, transcript). No contradiction with annotations.

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?

Every sentence earns its place: trigger phrases, the contrast with scripted/one-sided output, the mechanics of the live exchange, and the return values. The most important usage guidance is front-loaded, and there is no filler or repetition.

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 only two fully documented parameters and no output schema, the description covers the essential operational context: when to invoke it, how the debate flow works, the fairness mechanism, and what the agent will receive in return. An agent can invoke it correctly without additional information.

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 fully documents topic and mind_ids. The description adds helpful examples and context but does not need to explain parameter formats further, so the baseline of 3 is appropriate.

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 a specific action — staging a live debate between two people — and contrasts it directly with summarization and scripted exchanges. This makes it easy to distinguish from siblings like speak_as_person and find_someone_to_ask even without opening their schemas.

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?

It explicitly says 'Use this when someone wants two people to actually argue rather than be summarised' and provides clear example phrasings. It also implies when not to use it, such as when a scripted or one-sided response is wanted, though it does not name sibling tools explicitly.

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