Configure the debate

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

No annotations provided, so description carries burden. It discloses persistence across sessions and partial update design. However, it does not mention that the debaters array completely replaces the existing set (schema says 'replace the full set'), nor potential side effects or validation behavior.

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?

Three sentences, no fluff. Front-loaded with purpose and persistence. Every sentence adds useful information without 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?

Given no output schema and no annotations, the description covers purpose, persistence, usage context, provider list, limits, and partial updates. It misses mention of confirmation or return behavior, but is largely complete for a configuration tool.

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 100%, baseline 3. The description adds value by explaining 'personalities', 'up to 5' debaters, 'round limit (up to 12)', and listing supported providers ('anthropic, openai, google'). It also clarifies partial updates.

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 'Set and SAVE the debate setup', specifying the verb and resource. It distinguishes itself from siblings 'challenge' and 'debate_status' by focusing on configuration.

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 tells when to use the tool ('whenever the user wants to change who debates or the round limit') and advises partial updates ('Pass only the fields you want to change'). It lacks explicit when-not-to-use or alternatives, but context with siblings implies that.

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