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

With no annotations, the description fully discloses side effects: re-answering changes the answer and notes it in the thread, deadline-expired answers replace the prior outcome, the answer is written as an ordinary comment, and the asker is notified. This is rich, honest behavioral detail.

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?

Four sentences, each carrying meaningful information (action, permission, deadline behavior, thread/notification effect). No fluff, but slightly longer than necessary; still well-structured and front-loaded.

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 3 params and no output schema, the description covers the core behaviors: who can call, effects of re-answering, deadline handling, and how the result is recorded. It omits error cases (e.g., unauthorized attempts), but that is acceptable given the tool's simplicity.

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%, and each parameter already has clear descriptions (option counted from 0, questionId source, note as qualification). The description adds no new parameter-level meaning beyond what the schema provides, so the baseline of 3 applies.

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 (answer) and resource (a question on an issue) and distinguishes from siblings like ask_issue_question, withdraw_issue_question, and list_issue_questions by focusing on the answering action. The purpose is unmistakable.

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?

Provides clear context: only the addressee may answer, and a past deadline does not block answering. However, it does not explicitly name alternatives or state when not to use this tool, leaving some inference needed.

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