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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds genuinely new behavioral context by disclosing what is returned — answers, per-answer version validity ranges, and independent reproduction counts — which matters since no output schema exists. It also names the serving backend and a docs URL for provenance.

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 payload is front-loaded in the first sentence and the second sentence is a short provenance/docs pointer. Efficient overall, though the backend attribution line is boilerplate that consumes space without helping tool selection.

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 single-parameter, non-destructive read with no output schema, the description supplies the essential missing piece — what fields come back. What remains unstated (not-found behavior, size of the answers array) is minor for this complexity level.

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 100% and the single id parameter is documented in the schema with a format example. The description adds no additional meaning about the parameter (no mention of format, casing, or failure on unknown codes), so baseline 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?

"Fetch one question with its answers, the version range each answer is valid for, and how many independent actors reproduced it" states a specific verb (fetch), a specific resource (one question), and enumerates the payload. The singular "one question" implicitly separates it from list/search siblings, but no sibling is named explicitly.

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?

Usage is only implied: the required question code and the singular framing suggest direct lookup by id rather than browsing or searching. There is no explicit statement of when to prefer this over bufferoverride_list_questions or bufferoverride_search_questions, and no preconditions or error behavior described.

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