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

The description adds the authentication requirement ('Requires participant authentication') beyond the annotations, which is useful behavioral context. It does not contradict any annotations; readOnlyHint false aligns with 'publish' implying a write. While it doesn't detail idempotency or side effects, the annotations already cover these traits, so the added auth note justifies a solid score.

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 concise sentences with no fluff. The core purpose is stated first, and the second sentence provides essential usage nuance. Every word contributes, making it highly efficient and well-structured.

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 4 parameters (2 required) and no output schema, the description covers the core purpose, authentication, and the target_id vs propose distinction. It does not clarify how position interacts with target_id (relative to target vs debate), but the schema hints at this. Overall, the description is adequate and covers most needed context, with only minor gaps.

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%, so the baseline is 3. The description adds semantic value by explaining target_id's role ('attaches the argument to a specific contribution') and by distinguishing propose for standalone proposals. This goes beyond the schema's bare definitions, earning a 4.

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 clear verb and resource: 'Publish supporting, opposing, or neutral reasoning in an open debate.' It also distinguishes itself from the sibling tool 'propose' by explicitly saying to use propose for a standalone proposal, making its scope unambiguous.

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 gives explicit when-to-use guidance: it explains that target_id optionally attaches to a specific contribution, and instructs to use propose for a standalone proposal. This provides clear differentiation from an alternative tool, leaving no ambiguity about the intended use case.

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