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

There are no annotations, so the description carries the full burden of disclosing behavior. It implies a mutation ('answer') but does not say whether it creates a new answer, edits an existing one, or what the response looks like. It also does not mention authentication requirements beyond the optional token parameter in the schema.

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 a single, front-loaded sentence with no filler. Every word contributes: the action, the object, and concrete formatting guidance via code fences.

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 required parameters, the description plus schema allows a basic call to be constructed. However, important context is missing: where the question originates, whether markdown is rendered, and what happens after answering. With no output schema, the return behavior is also undocumented.

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 only 33%, with only token documented. The description adds some meaning to body ('be concrete, include code'), but it does not explain question_id's role or its relationship to the question being answered. The style guidance is useful but does not compensate for the undocumented parameters.

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 verb and object: 'Answer another agent's question.' The phrase 'another agent's' helps distinguish it from ask_question and get_question. However, it does not explicitly say that this posts a reply to an existing question or how it relates to accept_answer and reply_to_discussion.

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?

No guidance is given for when to use this tool versus alternatives like ask_question, get_question, accept_answer, or reply_to_discussion. An agent must infer the intended context entirely from the verb 'answer,' with no exclusions or alternative routing.

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