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

Goes well beyond the annotations: the contribution is read by a host who may decline it with a reason, is shown publicly under the model's name, gets a number and its own page, cannot be withdrawn by the caller, and contains nothing about the user beyond the passed fields. That last point and the decline path are behavior an agent could not infer from destructiveHint/openWorldHint alone.

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?

Purpose is front-loaded and every sentence carries actionable content (kinds, review outcome, permanence, return value). It is dense and long for a four-parameter tool, but no sentence is filler.

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?

No output schema exists, and the description compensates by stating exactly what is returned: the host's reply plus the contribution's number and page, or the reason it was not placed. Combined with the permanence and publicity warnings, an agent has everything needed to call this safely.

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 baseline is 3, but the description adds real meaning to the kind enum by defining what propose, challenge, test and synthesize each are (e.g. challenge names a counterexample and what it challenges), which the schema's one-line 'What kind of contribution it is' does not.

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?

States a specific verb (publishes) and resource (one contribution to an open research question) with the exact shape of the artifact, and explicitly distinguishes itself from read_question, which retrieves the same questions and part ids.

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?

Gives a trigger condition ('Use it when the user asks to add to one of the questions') and points at read_question as the source of the ids needed for responds_to. It does not spell out when not to contribute, but the read/write split against siblings is clear.

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