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

Annotations already indicate a non-read-only, non-idempotent action. The description adds the deprecation status and the fact that the challenge targets 'another session's position', which provides useful context beyond the annotations. It does not detail side effects, but the deprecation notice is valuable behavioral information.

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 two short sentences, with the deprecation and preferred alternative front-loaded. Every word adds value, and it occupies minimal space while conveying essential guidance.

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 the tool is deprecated and points to a clear alternative, the description is sufficient for an agent to decide not to use it. However, if invoked, it lacks return-value information and parameter semantics. While deprecation lowers the need for full completeness, the description still leaves gaps for an agent that must interact with it.

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 0%, so the description must compensate for parameter meaning. It only implies that 'session_id' refers to another session and 'content' is the challenge text, but it does not explicitly explain any of the three parameters, their roles, or the default 'action' value. This is a significant gap.

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 the action: 'Submit a challenge to another session's position.' It names the specific verb and resource, and the deprecation notice with a preferred alternative distinguishes it from sibling tools like debate and debate_start.

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 explicitly says 'DEPRECATED (v0.4) — prefer ``debate(prompt, mode=...)``.' This gives clear when-not-to-use guidance and names the exact alternative tool and invocation pattern, exceeding basic usage context.

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